Answer:

-2

Step-by-step explanation:

Simplify the following:

2 - 3 - 4 - 4 + 7

2 - 3 - 4 - 4 + 7 = (2 + 7) - (3 + 4 + 4):

(2 + 7) - (3 + 4 + 4)

2 + 7 = 9:

9 - (3 + 4 + 4)

3 + 4 = 7:

9 - (7 + 4)

7 + 4 = 11:

9 - 11

9 - 11 = -2:

Answer:  -2

Urgent! Please explain to me how to solve this. :)
igomit [66]

The population increases by 500 each year, so multiply the number of years that have passed since 1990 by 500.

1999 - 1990 = 9 years

9 years * 500 = 4,500

Add 4,500 to 22,317 inhabitants.

22,317 + 4,500 = 26,817

Your answer is B) 26,817 inhabitants.

Bx – 10 = f solve for x(z/2) - b = hSolve for z
Free_Kalibri [48]

1) To solve for x, is to let x on the left side and the other terms and variables on the right side.

bx -10=f <em>Add 10 to both sides</em>

bx = f+10 Divide by b on both sides

So that's the way we solve for x.

b) For this one we multiply the whole expression by 2 and then isolate z on the left side, and the rest on the right side.

z = 2h +2b

Three weeks ago John bought stock at 49 1/4; today the stock is valued at 49 7/8. We could say the stock is performing at which
Bad White [126]

Answer:

The correct option is D.

Step-by-step explanation:

John bought stock at 49\frac{1}{4}; today the stock is valued at 49\frac{7}{8}.

49\frac{1}{4}=49+\frac{1}{4}

49\frac{1}{4}=49+0.25

49\frac{1}{4}=49.25

The value of stock at the time of purchasing is 49.25.

49\frac{7}{8}=49+\frac{7}{8}

49\frac{7}{8}=49+0.875

49\frac{7}{8}=49.875

The value of stock at current time is 49.875.

49.875-49.25=0.625

The value of stock increased by 0.625.

Since the value of stock increases, therefore the correct option is D, i.e., Above par.
