Answer:

-8

Step-by-step explanation:

7-3(10:2):1

We always solve what's in parenthesies first.

7 - 3*5:1

Multiplication and division have equal priority, so we solve that part from left to right:

7 - 15:1 =

= 7 - 15 =

= -8

16,000 rolls of paper were purchased and 12,500 were sold at $1.79, what is the total ending inventory?
Maslowich
12,500 x 1.79 to find the price but 16,000 - 12,500 to get how many were left. 
12,500 x 1.79 = $22,375 that they made from selling. 16,000 - 12,500 = 3,500 rolls left in the inventory. This question confused me so I just gave both answers.

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

2(x + -5) + x = x + (-6)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Distributive Property] Distribute 2:                                                                 2x - 10 + x = x - 6
  2. [Addition] Combine like terms (x):                                                                   3x - 10 = x - 6
  3. [Subtraction Property of Equality] Subtract <em>x</em> on both sides:                         2x - 10 = -6
  4. [Addition Property of Equality] Add 10 on both sides:                                   2x = 4
  5. [Division Property of Equality] Divide 2 on both sides:                                  x = 2

Liono4ka [1.6K]

Answer:

\huge \frac{8}{45}

Step-by-step explanation:

\frac{9}{10}  -  \frac{13}{18}  \\  \\  = \frac{9 \times 9}{10 \times 9}  -  \frac{13 \times 5}{18 \times 5} \\   \\  = \frac{81}{90}  -  \frac{65}{90}  \\   \\ =  \frac{81 - 65}{90}\\  \\  =  \frac{16}{90}  \\  \\  =  \frac{8}{45}  \\
