Roman solved the equation 5a+2b=10 for a. His steps are shown below. 1. Subtract 2b: 5a+2b-2b=10-2b 2. Multiply by 5: 5a+10-2b W

VladimirAG [237]

Answer:

In step 2, he needed to divide both sides of the equation by 5

Step-by-step explanation:

we have

$5a+2b=10$

Solve for a------> That means isolate the variable "a"

step 1

Subtract 2b to both sides

$5a+2b-2b=10-2b$

$5a=10-2b$

step 2

Divide by 5 both sides

$5a/5=(10-2b)/5$

$a=(10-2b)/5$

3x^2+17x-9/x+4 what is the quotient

zvonat [6]

Answer:

The quotient of given expression is (3x+5).

Step-by-step explanation:

The given expression is

$\frac{3x^2+17x-9}{x+4}$

The coefficients of dividend are 3,17 and -9.

Use synthetic division to divide $3x^2+17x-9$ and $x+4$ .

The bottom row represents the coefficient of quotient and remainder.

The given expression can be written as

$\frac{3x^2+17x-9}{x+4}=3x+5-\frac{29}{x+4}$

Therefore the quotient of given expression is (3x+5).

A meal at a restaurant costs $49.28. If the customers leave $8.23 for a tip, determine the tip rate to the nearest whole percent

Ede4ka [16]

The cost for the total meal, I think, is $58. If you add 49.28 and 8.23, you get 57.51. I rounded to the nearest one and I got 58, so thats the answer I got. Hope this helps!
