Step-by-step explanation:
Tax charge
80 × 6.75/100 = 5.4
Cost + tax charge
80 + 5.4 = 85.4
Tip (15% of cost and tax)
85.4 × 15/100 = 12.81
(Cost + tax charge + tip)
85.40 + 12.81 = 98.21
therefore, $95 is not enough.
Answer:
6(x-10)=5-2(1-x)
Step-by-step explanation:
I divided by 3 the parenthesis, and multiplied by 3 the first number, which makes an equivalent equation.
Answer:
4x-12
Step-by-step explanation:
use distributive property and distribute the 4 through
Answer:
d
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
f(x) - g(x)
= x³ - 2x + 6 - (2x³ + 3x² - 4x + 2) ← distribute parenthesis by - 1
= x³ - 2x + 6 - 2x³ - 3x² + 4x - 2 ← collect like terms
= - x³ - 3x² + 2x + 4 → d
Let
x-------------> <span>the length of a rectangle
y-------------> the </span>width of a rectangle
we know that
x+y=130-----------> equation 1
and
x=1.6y--------------> equation 2
<span>I substitute 2 in 1
(1.6y)+y=130-------------> 2.6y=130------------> y=130/2.6------> y=50 ft
x=1.6y--------> x=1.6*50---------> x=80 ft
the answer is
</span>the length is 80 ft
the width is 50ft
