4.
The equation we have is:
To solve for "a", we want to isolate it in one side.
For this. we can start by multiplying each side by 5. This will make the denominator to cancel out:
Now, we can divide both sides by 8, which will cancel the coefficient 8 multiplying "a":
And that is the answer to 4.
The area of the trapezoid is given by the formula A= (a+b)/ 2 * h
in this question a= 8, b= 10, A= 108 inches², and h is what we have to find, substitute what we have got into the formula and you will have:
108= (8+10) /2 *h
108= 9 *h
h= 108/9
h= 12 inches
Answer:
10
Step-by-step explanation:
7x+5 = 9x -15
5 = 2x -15
2x = 20
x = 10
Answer: 875
Step-by-step explanation:
You can set up proportions so it’s like: 1/350=2.5/x and then solve for x
