Hey there!!
Given equation :
... 4x +3(x+2) = 5(2x-3)
Using the distributive property :
... 4x + 3(x) + 3 (2) = 5(2x) + 5(-3)
... 4x + 3x + 6 = 10x - 15
Combining the like terms :
... 7x + 6 = 10x - 15
Subtracting 7x on both sides :
... 6 = 3x - 15
Adding 15 on both sides :
... 21 = 3x
Dividing by 3 on both sides :
... x = 7
This is the solved equation. The first step we have done to solve the equation was using the distributive property.
Hope my answer helps!
Select and place the symbol that will make the statement true -|y| ? |-y|
It's [tex]\leq[/tex]
The correct symbol to make the statement -|y|? |-y| true is '=', because the absolute value of 'y' and '-y' are always equal, regardless of whether 'y' is positive or negative.
Explanation:The correct symbol to make the statement true is '='. This is because the absolute value of any number, positive or negative, is always positive, or zero in the case of zero itself. So no matter what value 'y' takes on, |-y| and |y| will always be equal.
For example, let's consider that y = -5. Then |-5| = 5 and |5| = 5. Here |-y| and |y| are equal.
If y = 5, then |-5| = 5 and |5| = 5. Here too, |-y| and |y| are equal. Therefore, no matter if 'y' is positive or negative, the absolute value of 'y' and '-y' are always equal.

[tex] \pi x^{2} [/tex] = a
The formule is about area of a circle.
[tex]\pi x^{2} = a[/tex]
We need to solve the equation for x. Where x is the radius of the circle.
In order to solve it for x, we need isolate it for x on left side.
So, first we need to get rid pi from left side.
On dividing both sides by pi, we get
[tex]\frac{\pi x^2}\pi}=\frac{a}{\pi}[/tex]
[tex]x^2=\frac{a}{\pi}[/tex]
Taking square root on both sides, we get

You are remodeling your kitchen. You’ve contacted two tiling companies who gladly told you how long it took their workers to tile a floor of a similar size. Jim completed half the floor in 12 hours . Pete completed the other half in 10 hours. If Pete can lay 25 more tiles per hour than Jim, what equation would you use to find the rate that Jim can lay tiles. Let x represent Jim’s rate
As given, let Jim's rate = x
Let Pete's rate =y
Jim completed half the floor in 12 hours so it's [tex]12\times rate[/tex]= 12x
Pete completed the other half of the floor in 10 hours so its [tex]10\times rate[/tex]=10y
As floor area is equal so,
[tex]12x=10y[/tex] .............(1)
Now, given is that Pete can lay 25 more tiles per hour than Jim, this gives=
[tex]y=x+25[/tex] ...... (2)
Putting the value of y from equation (2) in equation (1) , we get
[tex]12x=10(x+25)[/tex]
So, the equation is : [tex]12x=10(x+25)[/tex]
If you want to solve it, it becomes:
[tex]12x=10x+250[/tex]
[tex]2x=250[/tex]
[tex]x=125[/tex]
Hence, Jim can lay 125 tiles and Pete can lay 25 more so 125+25=150 tiles.

The population of a city can be modeled with a linear equation, y = –80x + 3,450, where x is the number of years after 2000 and y is the city’s population. Write a description of the city’s population based on the equation.
Answer:
Initial population is 3450 in the year 2000 and it decreases 80 every year.
Step-by-step explanation:
We are given with y=-80x+3450 where y is city's population and x is the number of years after 2000.
That is x=0 means the year 2000.
Hence y-intercept will represent the initial population which is nothing but 3450.
Since our equation slope =-80 which is negative means y is decreasing as x increases.
For x raises by 1, y decreases by 80.
That means population decreases by 80 for every year.
Answer:
The y-intercept indicates the population in the year 2000, so 3,450 people lived in the city in 2000. The negative slope indicates that the city is losing population. It loses 80 people each year.

which algebraic rule describes the 270° counter-clockwise rotation about the origin?
a) (x, y) → (−x, y)
b) (x, y) → (x, −y)
c) (x, y) → (y, −x)
d) (x, y) → (−y, x)
270 degree counter clockwise is the same as 90 degrees clockwise.
If you imagine the (x,y) axes rotating 90 clockwise, you will see that what x becomes y, and what was y becomes negative x (after the rotation).
So x-->y, and y-->-x
So the answer (c) is the correct one.
Answer:
option C
Step-by-step explanation:
the correct answer is option C
when a point (x, y ) means point lies in the first quadrant is rotated counter-clockwise to 270° means now the point will be in the fourth quadrant.
hence, in algebraic notation we interchange x by negative x
and y remains the same and their value interchanges so,
the best-suited answer will be (x, y) → (y, -x)
hence, the answer will be option C

22.48 rounded to the nearest whole number
ANSWER
22
EXPLANATION
22.48 rounded to the nearest whole number is 22.
The reason is that the 4 after the decimal point is less than 5 so we won't round up.
Answer:
The round off number is 22.
Step-by-step explanation:
The number = 22.48
Nearest whole number = 22
Explanation:
A whole number is any number which is without any decimal or fraction.The question was to round off the nearest of 22.48.Now the rule is that if the number left to decimal is 5 or more than 5, round of the number by adding 1 to the number right to the decimal. If the number left to decimal is 4 or less than 4 then round off number simply by removing all left to decimal.Now in our question there was 4 left to decimal. So we apply the second rule and the rounded off number will be 22.this afternoon,sara noticed that the number of the page assigned for homework is divisble by both 12 and 2.what is the smallest possible page number tha

liquid A has a density of 1.4 g/mL , liquid B has a density of 5.9 g/mL and liquid c has a density of 3.2 g/ mL. arrange the three liquids ina density column ( explain your answer)
Liquid B
Liquid C
Liquid A
Because the denser layers sink and the less dense layers float to the top, just like oil and water, the water is more dense than the oil, that is why the oil floats to the top and the water remains at the bottom:))
At the bottom of the density column there is liquid B with a density of 5.9 g/ml, in the middle liquid C with a density of 3.2 g/ml and in the middle liquid A with a density of 1.4 g/ml be at the top.
Explanation:
To arrange liquids A, B, and C in a density column, you must consider their respective densities, since the highest density liquid stays at the bottom and the lowest density liquid floats at the top. Liquid B has the highest density (5.9 g/ml), then liquid C with a density of 3.2 g/ml, then liquid A with the lowest density, 1.4 g/ml. Therefore, when arranging these liquids in a density column, place liquid B at the bottom, liquid C in the middle, and liquid A at the top.

.0825×30=2.475
now add 2.475+25.50+30= 57.975 round to 57.98
The final answer is 36.975. The expression simplifies to 36.975 when all calculations are completed.
1. 30 + (.0825 x 30):
To calculate this part, we first multiply 0.0825 (which is 8.25% written as a decimal) by 30. This gives us:
0.0825 x 30 = 2.475
Next, we add 30 to the result:
30 + 2.475 = 32.475
2. (15% x 30):
To calculate this part, we first convert 15% to a decimal by dividing it by 100:
15% = 15/100 = 0.15
Next, we multiply 0.15 by 30:
0.15 x 30 = 4.5
Now that we have the results from both parts, we add them together:

Determine the x- and y-intercepts of the graph of y=−13x+3 . Then plot the intercepts to graph the equation.
To find the x-intercept of the equation y = -13x + 3, set y to zero and solve for x to get (3/13, 0). For the y-intercept, set x to zero and solve for y, resulting in (0, 3). These intercepts are then plotted and connected to graph the equation.
Determining X and Y Intercepts
To determine the x-intercept of the linear equation y = -13x + 3, we need to set y to zero and solve for x:
0 = -13x + 3
13x = 3
x = 3/13
So, the x-intercept is (3/13, 0).
To determine the y-intercept, we set x to zero and solve for y:
y = -13(0) + 3
y = 3
Thus, the y-intercept is (0, 3).
Plotting the Intercepts
On graph paper, mark the x-intercept at (3/13, 0) and the y-intercept at (0, 3). Then use a ruler to draw a straight line that passes through these points; this line represents the equation y = -13x + 3.
The slope is the rate of change along a line. However, in this scenario, the slope is not required to plot the line since we already have the intercepts. Nonetheless, for your reference, the slope (m) in the equation y = mx + b corresponds to -13, indicating a decline of 13 units in the y-direction for each single unit increase in the x-direction.
