Answer:
x = -5
Step-by-step explanation:
Start by adding the 5x to each side of the equation to the left to get...
-25 = 5x + 25 + 5x
Then you would add 25 to each side of the equation to get...
0 = 10x + 25 + 25
Adding on, you would simplify this step to get...
0 = 10x +50
You would now have to make the x variable on one side alone so you would subtract 50 from both sides of the equation again to get...
-50 = 10x
Finally you would divide both sides of the equation by 10 to get x alone...
-50/10 = 10x/10
And simplify that to get...
x = -5

Answer:
36 ft
Step-by-step explanation:
So the proportion of the big triangle is 48:4 or 12:1. So if the small triangle’s height is 3 feet, then 3*12 is 36 feet.
Answer:
x≈ 100
Step-by-step explanation:
Given the equation
5x-496=1.34...
We are to find the value of x to the nearest whole number
Add 496 to both sides
5x-496+496 = 1.34+496
5x = 497.34
x = 497.34/5
x = 99.468
x ≈ 100
Hence the value of x to nearest whole number is 100
Answer:
the constant proportionality means the ratio between two directly proportional quantities.
so the constant proportionality will be 7.5÷6=1.25 or 10÷8=1.25 or 12.5÷10=1.25
constant proportionality should be same all through because it's a constant
