I want to know how to solve multi step equation

When solving multi-step equation you should start by combining like terms.

4x + 10 = 7x + 16

With this equation you can subtract 4x from each side. -4x = -4x

10 = 3x + 16

Then you can combine 16 and 10 by subtracting 16 from each side. -16 = -16

-6 = 3x

After that you try and isolate the variable. You can do this by dividing both sides by 3 which also isolates the variable. *1/3 = *1/3

-2 = x

So the final answer would be x = -2

We are given:

4x+10=7x+16

Our goal in solving for any variable, in this case is x, we need to isolate x on one side of the variable. Let's start by subtracting 7x from both sides, which will cancel the +7x on the right side. We are then left with:

-3x+10=16

Now, we want to move that +10 to the other side so our x is all by itself. Let's subtract 10 from both sides, which will cancel the +10 on the right leaving us with:

-3x=6

Since we cannot have a coefficient when solving for x, we need to divide both sides by -3.

\frac{-3x}{-3}={\frac{6}{-3}

When we divide, our answer is:

x=-2

I really need help with number 4. Please help me out!

So " the line of best fit " would be 5(h) to 200(m) .
Which would also be 5:200 .
So after you can divide, so 5/5 would be 1 and 200/5 would be 40.
So it would be 1 to 40 (1:40).
The equation would be 40x. 
If I helped please mark as brainliest . Thanks .

Answer: 32.52  

Step-by-step explanation :if I’m correct this is supposed to be a decimal ( here we use the dot not the comma ) but if so then 32.52 a good way to remember is 5 or more let it sore (meaning round up) four or less let it rest (meaning it stays the same)

suppose you have ab on a coordinate plane located at a(-3,-4) and b(5,-4). under a dilation centered at (9,0), ab becomes a'b' w
Galina-37 [17]
The distace between the center of dilation and point a is diven by:

d=\sqrt{(9-(-3))^2+(0-(-4))^2} \\  \\ =\sqrt{(9+3)^2+(0+4)^2}=\sqrt{12^2+4^2} \\  \\ =\sqrt{144+16}=\sqrt{160}=\sqrt{16\times10}=4\sqrt{10}

The distance between the center of dilation and point a' is given by:

d=\sqrt{(9-6)^2+(0-(-1))^2} \\ \\ =\sqrt{3^2+(0+1)^2}=\sqrt{3^2+1^2} \\ \\ =\sqrt{9+1}=\sqrt{10}

It can be seen that the distance from the center of dilation to the image is 1/4 times the distance from the centre of dilation to the preimage.

Therefore, the scale factor is 1/4.

Can someone please help me. And explain it please
Semmy [17]
We know the area of a small square is 24 in².

Assuming the small rectangles are all equal in area, the total area of the window is equal to 6 x 24 = 144 in².

Now looking at the big window, the total area = width x length so:
144 = 18 x width
width = 144 ÷ 18 = 8 in

Write an equation for the line that passes through coordinates ( 2,5) and (6,7)
Tema [17]

answer: y = 1/2x + 4

work:

let's use slope-intercept form to help model this equation:

y = mx + b

in slope intercept form, m = slope, b = y-intercept, and using those, any x and y values along the line should make an accurate equation using the form.

okay, so start by finding the slope. to do this, subtract the y values over the x values.

7 - 5 / 6 - 2

2 / 4

1 / 2

so, the slope is 1/2. let's plug this into our equation.

y = 1/2x + b.

next, we need to isolate b, so plug in x and y values and solve for b.

5 = 1/2(2) + b

5 = 1 + b

4 = b


so, b = 4. add that into the equation.

y = 1/2x + 4

so, we have the values we need, your equation is complete! i hope this helps, and have a great day! don't hesitate to ask if you need more help with this specific question! ♥ - eviezoom
