Answer:
y=-3 x=4
Step-by-step explanation:
y=3x+3
y=3x+3 y=x-1
+<u>1</u><u> </u><u> </u><u> </u><u> </u><u>+</u><u>1</u>
y+1=x
y=3(y+1)+3
y=3y+3+3
y=3y+6
<u>-3y=-</u><u>3y</u>
-2y=6
-y=3
<u>y=</u><u>-</u><u>3</u>
3=x-1
<u>+1=+1</u>
<u>4</u><u>=</u><u>x</u>
Step-by-step explanation:
4 + n + 7m
constants are just the numbers with no variables (letters)
so the constant is 4
coefficients are numbers multiplied by variables (letters)
so the coefficients are : 7 and 1
the error sarah made is forgetting the coefficient of n......because even if it is not written, n is the same as 1n....so basically, there is a coefficient for EVERY variable, even if its not written.

Answer:
10^100 is larger than 100^10.
Step-by-step explanation:
10^100 compared to 100^10, we have 10^100 greater. 100^50 would equal to 10^100, as 10^2=100. 10^100 would be much more than 100^10.
Hope the explanation helps!
The distributive property:
a(b + c) = ab + ac
2(x - 8) = 68
(2)(x) - (2)(8) = 68
2x - 16 = 68 |+16
2x = 84 |:2
x = 42
Answer: D. 42
