x+9=18+-2x
divide 2x from both sides
which makes it 3x+9=18
subtract 9 from the 18
which is 3x=9
divide 3 from both sides
which gives you x=3
x+9=18+(-2x) add the 2x to the x and you should get 3x+9=18. Then you would subtract the 9 from the 18 and should get 3x=9. Then just divide the 9 by the 3 and get x=3 which is your answer. Hope this helps!
How do you graph the inequality of 4x-2y≤6 ?
4x - 2y ≤ 6 subtract 4x from both sides
-2y ≤ -4x + 6 change the signs
2y ≥ 4x - 6 divide both sides by 2
y ≥ 2x - 3y = 2x - 3 - it's a linear function. We need only two points to plot the graph.
Choose any two values of x and calculate the values of y:
for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)
for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)

the number g devided by the number h is the same as seven more than twice the sum of g and h. translate into equation
Answer:
[tex]\frac{g}{h}=2(g+h)+7[/tex]
Step-by-step explanation:
1. You have that the number [tex]g[/tex] is divided by the number [tex]h[/tex]. Then:
[tex]\frac{g}{h}[/tex]
2. The words "is the same" indicates that you must write an equals sign after the division. Then, it says that it is seven more than twice the sum of [tex]g[/tex] and [tex]h[/tex]. This means that the sum of these two numbers are multiplied by 2 and then you must add 7:
[tex]\frac{g}{h}=2(g+h)+7[/tex]
A marching band 8-to- 5 step covers 5/8 yd per step.
How many yards does a band member move across the football field if he or she takes 30 1/2 steps?
5/8⋅30 1/2=
Express your answer as a fraction in simplest form.
After taking 30 1/2 steps, each covering 5/8 yard, a band member moves a total of 19 1/16 yards across the football field.
Explanation:The student asks how many yards a band member moves across the football field if he or she takes 30 1/2 steps where each step covers 5/8 yard. To find the total distance covered, we multiply the number of steps by the distance per step. Here's the calculation:
First, convert 30 1/2 to an improper fraction: (30 × 2) + 1 = 61/2.Now, multiply 61/2 by 5/8 to find the total yards covered: (61/2) × (5/8) = 305/16.To simplify, divide 305 by 16: the quotient is 19 with a remainder of 1, so the simplified fraction is 19 1/16 yards.The band member moves 19 1/16 yards across the football field after taking 30 1/2 steps at a 8-to-5 step interval.

VerZion sells the iPhone X for $899. If the monthly plan for service is $65 per month what is the linear equation for the cost of buying and using the new iPhone with Verizon. What is the total cost after 24 months ?
The linear equation for the total cost of buying and using the new iPhone with Verizon is total cost = $899 + ($65 * 24), which simplifies to $2459 for 24 months.
Explanation:To find the linear equation for the cost of buying and using the new iPhone with Verizon, we need to consider the initial cost of the iPhone and the monthly plan cost. Let's assume the initial cost of the iPhone X is $899 and the monthly plan is $65. We can represent the total cost after 24 months as a linear equation.
The equation can be written as:
total cost = initial cost + (monthly plan cost * number of months)
Since we want to find the total cost after 24 months, we substitute the values into the equation:
total cost = $899 + ($65 * 24)
Simplifying the equation:
total cost = $899 + $1560 = $2459
Therefore, the total cost after 24 months would be $2459.

A scuba diver descends 63 feet in 18 seconds. What integer represents the change in the divers position in feet per second?
Answer:
-3.5 feet/second
Step-by-step explanation:
A scuba driver descends 63 feet in 18 seconds.
The integer represents descends 63 feet = -63 feet
Rate of change per second = Distance divided by the number of second to reach the distance
= [tex]\frac{-63}{18}[/tex]

Help please, and thank you
Answer:
Refer below
Step-by-step explanation:
5) 9x+2 = 119 (alternate angles of a parallel line)
Hence 9x = 117: x=29 degrees.
6) 12x-8 and 108 are supplementary
Hence 12x+100 = 180 Or 12x= 80 :
x = 20/3
7) 5x+7 = 8x -71
(since vertically opposite angles equal and corresponding angles equal)
3x= 78 or x = 26
8) 7x-61 = 4x-7:3x= 54 orx = 18
9) 9x+25 = 13x-19
4x = 44: x=11: 17y+5 = 13(11)-19
y -7
10) 9x-36 =180 : x = 24: 8y+17 = 6(24)-7
8y =120: y =15
11) 7x-23 =49+3x(exterior angle of triangle)
Or 4x = 72: x=18 : 3x =11y-1
y =5
12) 5x-38 = 3x-4
2x = 34 or x =17
7y-20 = 5(17)-38

y = 67/7

3 hours 20 minutes + 1 hour 48 minutes = ___ days
A. .2278
B. .1951
C. .2417
D. .2139
The answer is C .2417 because you add them then divide by 7
To add 3 hours 20 minutes and 1 hour 48 minutes, you add the hours and minutes separately. Then convert the total to days.
Explanation:To add 3 hours 20 minutes and 1 hour 48 minutes, you can simply add the hours together and the minutes together separately. Start by adding the hours: 3 + 1 = 4 hours. Then add the minutes: 20 + 48 = 68 minutes. Since there are 60 minutes in an hour, you can convert the excess minutes to hours by dividing by 60: 68 ÷ 60 = 1 hour. This gives a total of 5 hours. Therefore, 3 hours 20 minutes + 1 hour 48 minutes = 5 hours 8 minutes.
To convert this to days, divide the total number of minutes (308) by 60 to get the number of hours (5) and then divide by 24 to get the number of days: 5 ÷ 24 ≈ 0.2083 days.

There are six different ways Alberto, Ben, and Chike can line up to form a wall defending against a penalty kick. This is a high school level Mathematical problem known as permutation. This kind of logic applies whenever the order of arrangement matters.
Explanation:The subject matter involves a combinatorial problem, specifically a permutation. In this situation, Alberto, Ben, and Chike can occupy any of the three positions in the lineup. As such, the number of permutations (P) can be calculated by multiplying the number of choices for each position. That is, there are three choices for the first position, two remaining for the second, and one for the third. Thus, the answer is P = 3*2*1 = 6 different ways.

Find the probability a random voltage is less than 124.2 volts
A. 0.40
B. 0.60
C. 0.10
D. 0.80
Answer:
its 0.60
Step-by-step explanation:
I did the quiz
The probability a random voltage is less than 124.2 volts is 0.60. Thus, option (C) is correct.
Explanation:To find the probability that a random voltage is less than 124.2 volts, we need to know the distribution of the voltages. Let's assume that the distribution follows a normal distribution.
The Z-score formula is
Z = (X - μ) / σ,
where X is the value we are interested in, μ is the mean of the distribution, and σ is the standard deviation.
We want to find the probability that a random voltage is less than 124.2 volts.
Since the voltage is uniformly distributed, we can find this probability by calculating the proportion of the range that is less than 124.2 volts.
The range of the voltage is 125 - 123 = 2 volts.
The proportion of the range that is less than 124.2 volts is
= 124.2 - 123
= 1.2 volts / 2 volts
= 0.60.
Therefore, the probability a random voltage is less than 124.2 volts is 0.60.

if the original price was $19 then the price now would be $12.35. we would solve this by turning 35% into a decimal.. we get .35
what we do next is multiply 19 by .35 and we get 6.65
next, we subtract 6.65 from 19
