Elis [28]

Answer:

$148

Step-by-step explanation:

We are given the expression:

48+25h

We are also given h=4. Since we know what h is equal to, we can substitute 4 in for h.

48 + 25h (h=4)

48 + 25(4)

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

First, multiply 25 and 4.

48+ (25*4)

48+100

Next, add 48 and 100

48+100

148

The customer will have to pay $148

Super ez im just slow plz help<br> -3x+15-6x=30+32x
strojnjashka [21]

Answer:

-15/41

Step-by-step explanation:

-3x + 15 - 6x = 30 + 32x

~Combine like terms

-9x + 15 = 30 + 32x

~Subtract 15 to both sides

-9x = 15 + 32x

~Subtract 32x to both sides

-41x = 15

~Divide -41 to both sides

x = -15/41

Best of Luck!
