1. identity → distributive property on the right gives you 8x + 24 same as right

2. contradiction → left side simplified 4x + 18; right side simplified 4x + 16

3. neither → left side simplified 21x - 14; right side 20x - 13

4. identity → left side simplified 5x - 20; right side simplified 5x - 20

Identity equations have infinitely many solutions (any real number will work)
Contradiction equations have no solution (variable will cancel out and remaining statement is false)
Neither will have one solution for the equation (x coefficients are different)

the price for dinner in a resteraunt was $80. The customer paid an addition 7% meals tax and left a $15 tip. how much meals tax

Marrrta [24]

Multiply the price of the meal by the sales tax. Tips are added in after tax has been applied, so it would not be added in to calculate the tax.

Tax= Meal Cost * Tax %

=$80 * 7%
convert % to decimal (7% ÷ 100)

=80 * 0.07

=$5.60 sales tax paid

ANSWER: $5.60 was the sales tax the customer paid.

Lana71 [14]

Answer: 48 days

Step-by-step explanation:

Given

Ant takes 6 days to consume $\dfrac{3}{8}$ of an apple

Using unitary method

$6\ \text{days}\rightarrow \quad \frac{3}{8}\ \text{of an apple}\\\\1\ \text{apple takes}\rightarrow \quad \frac{8}{3}\times 6=16\ \text{days}\\\\3\ \text{apples take}\rightarrow\quad 16\times3=48\ \text{days}$
