Answer:
<h2>x = 7</h2>
Step-by-step explanation:
Simplifying
x + 20 = 5x + -8
Reorder the terms:
20 + x = 5x + -8
Reorder the terms:
20 + x = -8 + 5x
Solving
20 + x = -8 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
20 + x + -5x = -8 + 5x + -5x
Combine like terms: x + -5x = -4x
20 + -4x = -8 + 5x + -5x
Combine like terms: 5x + -5x = 0
20 + -4x = -8 + 0
20 + -4x = -8
Add '-20' to each side of the equation.
20 + -20 + -4x = -8 + -20
Combine like terms: 20 + -20 = 0
0 + -4x = -8 + -20
-4x = -8 + -20
Combine like terms: -8 + -20 = -28
-4x = -28
Divide each side by '-4'.
x = 7
Simplifying
x = 7
(9x 10^-3)^2=
, so d 8.1x10^-6
Evaluate 1/2a^-4b^2 for a =-2 and b=4
A number raised to a negative exponent is sometimes negative.

Answer:
6.67 yards
Step-by-step explanation:
20 feet. The builder asks him to give the measurements in yards. What will be the length in yards?
Please note that:
1 foot = 0.333 yard
20 feet = x yards
Cross Multiply
1 foot × x yards = 20 feet × 0.333 yards
x yards = 20 feet × 0.333 yards/1 foot
x yards = 6.66667 yards
Approximately = 6.67 yards
Therefore, the measurements in yards is 6.67 yards.
Answer:
Option 4

y = -5x + 2
-8 = -5(2) + 2
-8 = -10 + 2
Correct! :)
6 eggs= 7 days
