Answer and Step-by-step explanation:

<em>116 b.</em>

2^{10} = 1024\\2^8 = 256\\\\1024 + 256 = 1280\\\\\\2^5 = 32\\2^3 = 8\\\\32 - 8 = 24

1280 × 24 = 30720

<u>30720 ÷ 60 = 512. 512 is the solution; the expression is divisible by 60.</u>

<em>116 c.</em>

16^3 = 4096\\8^3 = 512\\\\4096 - 512 = 3584\\\\\\4^3 = 64\\2^3 = 8\\\\64 + 8 = 72

3584 × 72 = 258048

<u>258048 ÷ 60 = 4096. 4096 is the solution; the expression is divisible by 63.</u>

<em>116 d.</em>

125^2 = 15625\\25^2 = 625\\\\15625 + 625 = 16250\\\\\\5^2 = 25\\\\25 - 1 = 24

16250 × 24 = 390000

<u>390,000 ÷ 39 = 10,000. 10,000 is the solution; the expression is divisible by 39.</u>

The product of a number and five is eight
artcher [175]

Answer:

Assuming x is the number, then x=1.6

Step-by-step explanation:

If the product of a number and 5 is 8, the equation becomes:

5x=8 (assuming x is the unknown number).

We can isolate the variable x by dividing both sides by 5.

5x\div5 = 8\div5\\x = 1.6

In bulk, jelly beans cost 18 cents per ounce. What is the cost of the jelly beans in dollars per pound?
Diano4ka-milaya [45]

So we know that there are 16 ounces in one pound, so let's multiply to find how many cents one pound of jelly beans cost:

16*8=128cents

And we know that there are 100 cents in one dollar, so let's divide this by 100:

\frac{128}{100}=1.28

So the jelly beans cost $1.28 per pound.

A chemist mixes a 10% hydrogen peroxide solution with a 25% hydrogen peroxide solution to create 30 liters of a 15% hydrogen per
iris [78.8K]
Let x represent the amount of 10% solution used.
Let y represent the amount of 25% solution used.

Since 30 liters of 15% solution are being made, our first equation is
x + y = 30

Now we deal with the actual peroxide in each solution.
x liters of 10% peroxide contain 0.1x liters of peroxide.
y liters of 25% peroxide contain 0.25y liters of peroxide.
30 liters of 15% peroxide contain 0.15 * 30 = 4.5 liters of peroxide.
From this information, we can write our second equation.

0.1x + 0.25y = 4.5

We have a system of equations:

x + y = 30
0.1x + 0.25y = 4.5

Multiply the first equation by -0.25 and add to the second equation.

-0.25x - 0.25y = -7.5
   0.1x + 0.25y = 4.5
---------------------------
-0.15x              = -3

x = 20

Answer: 20 liters
