Solving for x would look like
rewrite: -4(2-1.2x)=40
distribute: -8+4.8x=40
add 8 to both sides of the equation: 4.8x=48
isolate x: x=10
So x = 10
This is the answer, attached below. :)
Scale factor is used as multiplier or divider
If one size is 1.266, the next large size will be 1.125 larger than 1.266
1.266×1.125=1.424
The real answer for this question is 3
Answer:
Step-by-step explanation: write the equation in the form of a proportion
2 1/2 is to 4 as something is to 3
2 1/2 / 4 = x/3
Then, cross multiply 2 1/2 x 3 or
5/2 x 3/1 = 15/2
Next cross multiply 4•X= 4X
Write as 4X = 15/2
Divide both sides by 4.
4X/ 4 = 15/2 /4
x = 15/2÷ 4/1
Divide by changing the sign to multiplication and inverting 4/1 to 1/4 like this:. 15/2. × 1/4= 15/8
Finally, 15/8 simplifies to 1 7/8 cups
