Answer:
x=15
Step-by-step explanation:
Hey There!
So what we want to do is inverse operations from the formula of area of a triangle
The area is equivalent to
h=height
b=base
now we setup an equation with what we are given
we are given A (area) and h(height)
so the equation looks like...
now we solve for b (x)
step 1 multiply each side by 2
75x2=150
/2x2 cancels out
now we have
150=10b
step 2 divide each side by 10
150/10=15
10/10 cancels out
b=15
We can conclude that the base (aka x) is equal to 15
Answer:
The answer is x=2-(y/2)
Step-by-step explanation:
The correct answer is D/ $-282
In order to solve for the other binomial, it's a hit-and-miss game :) Kind of
We know that in order to get x^2 there has to be an x multiplied by an x
(x + 9) (x (+/-) __)
What multiplied by 9 equals - 36 but also when added to nine equals 5?
Answer:
The solution of the equation 9x=7(x+2) is:
Option D) 7
Step-by-step explanation:
9x=7(x+2)
Eliminating the parentheses applying distributive property:
9x=7(x)+7(2)
Multiplying:
9x=7x+14
Grouping the x's on the left side of the equation: Subtracting 7x both sides of the equation:
9x-7x=7x+14-7x
Subtracting:
2x=14
Solving for x: Dividing both sides of the equation by 2:
2x/2=14/2
Dividing:
x=7
Solution: x=7 (option D)
