Answer:

D. 29

Step-by-step explanation:

First, let's make things a bit easier for ourselves and convert mixed numbers to improper fractions

-\frac{10}{3}* -\frac{87}{10}

Next, we check for numbers that can cancel out. In this case, we have 10.

-\frac{1}{3}*-\frac{87}{1}

Because negatives cancel out, we get

\frac{87}{3}

when we multiply.

Fractions just mean division, so we divide 87 by 3 and get

D. 29

Given that 2x + 1 =5, what is the value of (x+3)^3
Alla [95]

Answer: 125

Step-by-step explanation:

First, solve for x in the first equation.

1) Subtract 1 from both sides.

2x = 4

2) Divide by 2 on both sides.

x = 2

Next, substitute the value of x into the second expression.

(2 + 3)^3

= 5^3

4(y+8)=100 help me pls due today
Otrada [13]

Answer:

y=17

Step-by-step explanation:4(y+8)=100

We move all terms to the left:

4(y+8)-(100)=0

We multiply parentheses

4y+32-100=0

We add all the numbers together, and all the variables

4y-68=0

We move all terms containing y to the left, all other terms to the right

4y=68

y=68/4

y=17
