Answer:
x = 20
Step-by-step explanation:
The two angles are verticals angles and vertical angles are equal
7x -99 = 2x+1
Subtract 2x from each side
7x-99-2x =2x+1-2x
5x-99 =1
Add 99 to each side
5x-99+99 = 1+99
5x =100
Divide each side by 5
5x/5 =100/5
x = 20
Answer:
∠b = 90°
Step-by-step explanation:
If you wrote it correctly then ∠d will = 90°, right?
We have AB ║(which is parallel to) D => ∠b = ∠d = 90°
P/S: I think that you took the wrong photo, the right question should be above. I'm very please if you can take it again and I will write the right solution down below in the comment section (if u don't mind)
When two fractions have the same numerators, the one with the smaller denominator is the greater fraction.
![30 < 32 \Rightarrow \frac{22}{30} > \frac{22}{32}](https://tex.z-dn.net/?f=30%20%3C%2032%20%5CRightarrow%20%5Cfrac%7B22%7D%7B30%7D%20%3E%20%5Cfrac%7B22%7D%7B32%7D)
So Kelvin is right.
13 units... it's actually right triangle with sides 5 and 12, you just need to find hypotenuse
Answer: 4h - 3
<u>Step-by-step explanation:</u>
replace "x" with "h - 1" and simplify
f(x) = 3x + h
f(h - 1) = 3(h - 1) + h
= 3h - 3 + h
= 4h - 3
