Sherrie invested some money at 6% interest. Sherrie also invested $249 more than 4 times that amount at 12%. How much is investe

Anon25 [30]

Answer:

6%: $1776
12%: $7353

Step-by-step explanation:

Let x represent the amount invested at 6%. Then the amount invested at 12% is 4x+249. Sherrie's interest is ...

0.06x +0.12(4x +249) = 988.92

0.54x + 29.88 = 988.92

0.54x = 959.04

x = 959.04/0.54 = 1776

4x+249 = 7353

Sherrie invested $1776 at 6% and $7353 at 12%.

Which factorization is equivalent to this expression?

grigory [225]

Answer:

$10(3x+7)$

Step-by-step explanation:

we have the expression:

$30x + 70$

To factor this expression we need to indentify the components that are common in both terms.

At first glance there is nothing in common, but we can notice that 30 and 70 are multiples of 10, that is:

$10*3=30\\10*7=70$

so we can substitute this into the expression:

$10*3x+10*7$

and now that we have the common term (the number 10) we can factorize it, that is, take out the common term and include a parentheses:

$10(3x+7)$
