Please help!! Been trying for so long the way my teacher taught it, but cannot get right answer.
Rama09 [41]
River C : 200 + x
River D: x

200 + x + x = 5,540
combine like terms

200 + 2x = 5,540
subtract 200 from both sides

2x = 5,340
divide both sides by 2 to isolate the variable

x = 2, 670

River C: 200 + x = 200 + 2,670 = 2,870
River D: x = 2,670

2,870 + 2,670 = 5,540

2 to the Third power -(30÷5) +9
OLga [1]

Answer:

11

Step-by-step explanation:

2^3-(30/5)+9

First, you divide 30/5 because it is in parentheses and we are following this rule for order of operations:

P- parentheses

E- exponents

M- multiplication

D- division

A- addition

S- subtraction

so 30/5 = 6 and plugged in is:

2^3-(6)+9

Next, we do exponents:

2^3 = 2x2x2 = 8

plugged back in:

8-(6)+9

Now, we do the math from left to right so:

8-6=2

2+9=11

11 is your answer
