Answer:
First Question: x = -8
Step-by-step explanation:
-12x + 4 = 100
firstly we subtract 4 from 4 which will remove it from the equation and then we also subtract 4 from 100.
Now the equation will be -12x=96
Then we divide -12x by -12 to figure out the value of x and we also dive 96 by -12.
-12x/-12= 96/-12
Answer is x = -8
Hopefully that helped :)
Area of the whole circle = 3.14 * 7.5^2
area of the sector = (3.14 * 7.5^2 * 210) / 360
= 103 cn^2 to nearest whole number
The nearest tenth means 1 decimal place.
so the answer is 8.5

Answer:
y=1 x=1
Step-by-step explanation:
2x + y = 3
x = 2y - 1
.
It looks like I could substitute the x=2y-1. Into 2x+y=3
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1
x=1
