Answer:
Step-by-step explanation:
Simplifying
3.4 + 2(9.7 + -4.8x) = 61.2
3.4 + (9.7 * 2 + -4.8x * 2) = 61.2
3.4 + (19.4 + -9.6x) = 61.2
Combine like terms: 3.4 + 19.4 = 22.8
22.8 + -9.6x = 61.2
Solving
22.8 + -9.6x = 61.2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-22.8' to each side of the equation.
22.8 + -22.8 + -9.6x = 61.2 + -22.8
Combine like terms: 22.8 + -22.8 = 0.0
0.0 + -9.6x = 61.2 + -22.8
-9.6x = 61.2 + -22.8
Combine like terms: 61.2 + -22.8 = 38.4
-9.6x = 38.4
Divide each side by '-9.6'.
x = -4
Simplifying
x = -4
Answer:
x=3
Step-by-step explanation:
1. Simplify the expression
7x-\left(3\cdot\left(x-6\right)\right)=30
Solve by distributing:
7x-\left(3x+3\cdot-6\right)=30
Simplify the arithmetic:
7x-\left(3x-18\right)=30
Expand the parentheses:
7x-3x+18=30
Simplify the arithmetic:
4x+18=30
The greatest common factor of #14 is 8, and for #16 the answer is 19
Answer:
The total cost of the crown molding is <u>$23.43</u>.
Step-by-step explanation:
