Answer:
x = 21
Step-by-step explanation:
We know that a triangle equals to 180 degrees.
Combine like terms. (x + 3x) and (-4 + 100)
x - 4 + 3x + 100 = 180
Subtract 96 on both sides.
4x + 96 = 180
-96 -96
Divide 4 on both sides.
4x = 84
--- -----
4 4
And you get a solution of 21.
x = 21
<u>Check:</u>
Substitute 21 into x.
Add/Subtract from left to right.
21 - 4 + 3(21) + 100 = 180
17 + 63 + 100 = 180
80 + 100 = 180
180 = 180
Answer:
592
Step-by-step explanation:
A=2(wl+hl+hw)
A=2(8*10+12*10+12*8)=592
Simple
scientific notation
8.009 × 10-3
So "one fourth of her number" basically means 1/4 of an unknown number, x. So 1/4x. then susan subtracts 11. So its 1/4x - 11 = 11 (because she gets 11)
Answer:
Slope is -1/4 or -.25
Step-by-step explanation:
y=mx+b
slope is "m" and always has to be infront of x.
