OK. Great. Thanks for sharing. Do you have a question to ask ?
My hunch is that you want to know what the "number" is.
Here's how to set it up and solve it:
"a number" . . . . . . . . . . . . . . . Q
"The difference of
a number and 17" . . . . . . . . . . Q - 17
"eight times the difference" . . . 8 (Q - 17)
"is thirty" . . . . . . . . . . . . . . . . . . 8 (Q - 17) = 30
Eliminate parentheses on the left side:
8Q - 136 = 30
Add 136 to each side: 8Q = 166
Divide each side by 8 : Q = 20.75
Answer:
m<CAO = 56
Step-by-step explanation:
When two parallel lines are intersected by a transversal, the same-side interior angles are supplementary, meaning that their angle measures add up to (180) degrees. Using this information, substitute in the given values and solve for the unknown,
(m<DOA) + (m<CAO) = 180
Substitute,
3x + 40 + 2x = 180
Simplify,
5x + 40 = 180
Inverse operations,
5x + 40 = 180
-40 -40
5x = 140
/5 /5
x = 28
Now substitute the value of (x) back into the given expression for the value of (<CAO). Solve to find the numerical value.
<CAO = (2x)
= 2(28)
= 56
