in this, the blank is 'y'. I filled the x with -8
)(−8)−(−8−40)=(2)(−8)−(y−8)
Step 1: Simplify both sides of the equation.
(10)(−8)−(−8−40)=(2)(−8)−(y−8)
(10)(−8)+−1(−8−40)=(2)(−8)+−1(y−8)(Distribute the Negative Sign)
(10)(−8)+(−1)(−8)+(−1)(−40)=(2)(−8)+−1y+(−1)(−8)
(10)(−8)+8+40=(2)(−8)+−y+8
−80+8+40=−16+−y+8
(−80+8+40)=(−y)+(−16+8)(Combine Like Terms)

Shen the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the other (not both). On Friday there were 3 clients who did Plan A and 5 who did Plan B. On Saturday there were 6 clients who did Plan A and 2 who did Plan B. Shen trained his Friday clients for a total of 10 hours and his Saturday clients for a total of 10hours. How long does each of the workout plans last?
Answers
To find the duration of workout plans A and B offered by Shen, we set up a system of linear equations and solved them. Both plans last 1.25 hours each.
Explanation:Let us denote the duration of workout Plan A as A hours and Plan B as B hours. We can use the provided information to set up a system of linear equations representing the total training time on each day. On Friday, 3 clients did Plan A and 5 did Plan B for a total of 10 hours, leading to the equation 3A + 5B = 10. On Saturday, 6 clients did Plan A and 2 did Plan B for a total of 10 hours, resulting in the equation 6A + 2B = 10.
To solve this system of equations, we can use substitution or elimination. Multiplying the first equation by 2 gives us 6A + 10B = 20. Then we can subtract the Saturday equation from this to find the value of B:
(6A + 10B) - (6A + 2B) = 20 - 108B = 10B = 1.25 hoursNow that we know the duration of Plan B, we can plug this into either of our original equations to find the duration of Plan A. Let's use the Friday equation for this purpose:
3A + 5(1.25) = 103A + 6.25 = 103A = 3.75A = 1.25 hoursAs it turns out, both workout plans last the same amount of time, 1.25 hours each.
Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary of $650 per week. How much did she earn last week if she sold $4,400 in electronics merchandise? Round your intermediate calculations and answer to the nearest cent.
Answers
Danielle earned $969 last week if she sold $4,400 in electronics merchandise
Solution:Given that, Danielle earns a 7.25% commission on everything she sells at the electronics store where she works.
She also earns a base salary of $650 per week.
We have to find how much did she earn last week if she sold $4,400 in electronics merchandise?
Now, we know that, earned amount = base salary + commission
Given that she earns a 7.25% commission on everything she sells
So commission earned for selling $ 4400 is given as:
commission earned = 7.25 % of 4400
[tex]\text { commission earned }=\frac{7.25}{100} \times 4400=7.25 \times 44=319[/tex]
Earned amount = base salary + commission = 650 + 319 = 969
Hence, she earned $969 last week
The diagonal of a square measured 7 square root of 2 cm. Find the length of a side of the square
Answers
The diagonal of a square measured 7 square root of 2 cm. Then the length of side of square is 7 cm
Solution:
Given that,
The length of diagonal of a square is [tex]7 \sqrt{2}[/tex] cm
The figure is attached below
So length of diagonal = AC = [tex]7 \sqrt{2}[/tex] cm
Let the length of sides of the square be ‘a’
Since, the diagonal and the sides are forming a right angled triangle
So, we can use Pythagoras theorem,
Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
In triangle ABC, AC forms the hypotenuse and BC is the perpendicular and AB is the base
So above Pythagoras theorem definition,
[tex](\mathrm{BC})^{2}+(\mathrm{AB})^{2}=(\mathrm{AC})^{2}[/tex]
[tex]\begin{array}{l}{(a)^{2}+(a)^{2}=(7 \sqrt{2})^{2}} \\\\ {2 a^{2}=98} \\\\ {a^{2}=98 \div 2=49} \\\\ {a=\sqrt{49}=7}\end{array}[/tex]
Hence, the length of the square is 7 cm

A number line from negative 5 to 5 in increments of 1. An open circle is at 2 and a bold line starts at 4 and is pointing to the right.
Answers
The number line which represents the solution of 2.5 -1.2 x < 6.5 - 3.2 x is " A number line from negative 5 to 5 in increments of 1. An open circle is at 2 and a bold line starts at 2 and is pointing to the left "
Step-by-step explanation:
On the number line, when we represent the solution of an inequality:
If the sign of inequality is ≥ or ≤ we draw a black circle to represent the numberIf the sign of inequality is > or < we draw an open circle to represent the numberIf the sign of inequality is > or ≥, then the line starts from a point and is pointing to the rightIf the sign of inequality is < or ≤, then the line starts from a point and is pointing to the left∵ 2.5 -1.2 x < 6.5 - 3.2 x
- Add 3.2 x to both sides
∴ 2.5 + 2 x < 6.5
- Subtract 2.5 from both sides
∴ 2 x < 4
- Divide both sides by 2
∵ x < 2
∴ The solution of the inequality is x < 2 ⇒ all numbers less than 2
∵ The sign of inequality is <
- By using the points above
∴ The solution represented on the number line by an open circle
is at 2 and the line starts at 2 and pointing to the left
The number line which represents the solution of 2.5 -1.2 x < 6.5 - 3.2 x is " A number line from negative 5 to 5 in increments of 1. An open circle is at 2 and a bold line starts at 2 and is pointing to the left "

use two unit multipliers to convert 628 kilometers to centimeters
Answers
Using two unit multiplier 628 km is equal to 62800000 cm
Solution:
628 kilometer to centimeter
We will go from kilometers to meters to centimeters.
Start by putting 628 km over 1:
[tex]\frac{628 km}{1}[/tex]
We want to get rid of km and bring in m.
We know that 1000 m = 1 km.
Since km is in the numerator, we will make the first unit multiplier by putting 1 km in the denominator and 1000 m in the numerator, so the km will cancel. So we multiply by the unit multiplier,
[tex]\frac{628 km}{1} \times \frac{1000m}{1km}[/tex]
Now the km's will cancel:
[tex]\frac{628}{1} \times \frac{1000m}{1}[/tex]
Now we want to get rid of m and bring in cm.
We know that 100 cm = 1 m.
Since meter is in the numerator, we will make the first unit multiplier by putting 1 meter in the denominator and 100 cm in the numerator, so the meter's will cancel. So we multiply by the unit multiplier
[tex]\frac{100cm}{1m}[/tex]
[tex]\frac{628}{1} \times \frac{1000m}{1} \times \frac{100cm}{1m}[/tex]
We cancel the m's and we end up with:
[tex]628 \times 1000 \times 100 cm[/tex]
= 62800000 cm
Thus 628 km is equal to 62800000 cm
Final answer:
To convert 628 kilometers to centimeters, multiply by the conversion factors for kilometers to meters and then meters to centimeters, leading to 62,800,000 centimeters.
Explanation:
To convert 628 kilometers to centimeters, we need to apply two unit multipliers. The first conversion factor is 1 kilometer = 1000 meters, and the second conversion factor is 1 meter = 100 centimeters.
First, we convert kilometers to meters:
628 km × 1000 m/km = 628,000 meters
Then, we convert meters to centimeters:
628,000 m × 100 cm/m = 62,800,000 centimeters
Therefore, 628 kilometers is equal to 62,800,000 centimeters.

describe a situation that can be modeled by the integer -15 explain what zero represents in the situation
Answers
Answer:
Step-by-step explanation:
The current weather in a strange place is known to be 0 degrees, after a couple of hours, the weather has dropped 15 degrees, making the day much more colder than usual. What's the degree after the weather has dropped?
Solution:
0-15=-15
The integer -15 can be used to describe a situation of temperature falling below freezing point or owing someone money. In these situations, zero represents the freezing point or balanced position (no debt) respectively.
Explanation:A situation that can be modeled by the integer -15 could be the temperature outside on a very cold day in winter. If we are expressing the temperature in degrees Fahrenheit, for instance, a temperature of -15 could represent a day that is 15 degrees below the freezing point, which is 32 degrees Fahrenheit. In this situation, the integer zero represents the freezing point. So, if the temperature is -15, it means the temperature is 15 degrees below the freezing point.
Another example could be a debt. If you owe someone $15, then your balance can be represented by -15. In this case, zero represents the point where you do not owe any money, it is the neutrally balanced point of your financial situation.

roberto has 200$ to spend on tickets to the hockey game . since each ticket costs $30, that means he could purchase 6.67 tickets with his $200. how many tickets can he buy ?
Answers
Answer:
6 tickets
Step-by-step explanation:
you can't round it so just says 6 tickets with left over money
The number of tickets Roberto can buy with his $200 is 6 tickets.
The total amount Roberto has to spend on tickets = $200.
The cost of each ticket = $30.
We need to find the number of tickets Roberts can buy for the hockey game.
Total amount to spend on ticket = $200.
Cost of each ticket = $30.
The number of tickets possible to buy with $200 :
= 200 / 30
= 6.67 tickets.
We can not have 6.67 tickets so we can say 6 tickets.
Since each ticket cost $30, the total cost for the ticket is :
= 6 x $30
= $180
So after buying 6 tickets Roberto will be left with $20.
The number of tickets Roberto can buy with his $200 is 6 tickets.

Mara's family is driving to her grandmothers' house. The family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m. Write an equation that Mara can use to determine their average rate of travel, R, rounded to the nearest mile per hour.
Use the given numbers and operations to complete an equation.
Answers
Mara's family's average rate of travel, R, is calculated by dividing the total distance of 239.4 miles by the total time of 4.5 hours and then rounding to the nearest mile per hour.
To determine Mara's family's average rate of travel, R, you should start by calculating the total travel time. They started at 9:10 a.m and ended at 1:40 p.m, which is a span of 4 hours and 30 minutes, or 4.5 hours when converted to decimals to match the units of the distance traveled. Now use the formula for average speed, which is distance divided by time.
So, R = total distance / total time.
Substitute the given values into this formula to arrive at R = 239.4 miles / 4.5 hours. To find the average rate of travel, rounded to the nearest mile per hour, you would complete the division and then round the result.
Example Equation:
R = 239.4 miles / 4.5 hours
