Answer:

Yes, Sierra is correct

Step-by-step explanation:

Given

4(y + 7) > -3 (4 + 5)

Required

Is she correct

The right parenthesis has 4 + 5.

This can be simplified as: 4 + 5 = 9

So, we have:

4(y + 7) > -3 (4 + 5)

4(y + 7) > -3 *9

The left parenthesis has y + 7.

This cannot be simplified because y is a variable and 7 is a number.

<em>Hence, Sierra is correct.</em>

One safe investment pays 8% per year, and a more risky investment pays 12% per year.
Mice21 [21]

Principal = 109,000

Return - 9,920

Return = (principal x rate x time)/100

X = the amount invested at 12%

Then 102000- x = the amount invested at 8%

9920 = (x*12)/100 + (109000-x*8)100

x = 30,000

a) 30,000 is invested at 12%

79,000 is invested at 8%

b) The 12% investment is riskier so if all the money was in that account the investor could lose all his money.
