Let us pretend x is the number.
The equation will be 13-6x=11+4x.
Solve.......
X=2/10
Answer:
860
Step-by-step explanation:
Eight hundred and sixty.
<span>10x-5y=25 solve for y
so
10x - 5y = 25
5y = 10x - 25
y = 2x - 5

(4x-7y)(4x+7y)
4x times 4x= 16x^2
-7y times 7y= -49y^2
Answer:
25
Step-by-step explanation:
We can use the Pythagorean theorem to determine the length of the hypotenuse
a^2 + b^2 = c^2
15^2 + 20 ^2 = c^2
225 + 400 = c^2
625 = c^2
Take the square root of each side
sqrt(625) = sqrt(c^2)
25 = c
