Answer - D

6 - 3(2x - 4) = 2(1 + x)
6 - 6x + 12 = 2 + 2x
18 - 6x = 2 + 2x
18 = 2 + 8x
16 = 8x
2 = x

6 - 3(2x - 4) = 2(1 + x)
6 - 3(2x) + 3(4) = 2(1) + 2(x)
 6 - 6x + 12 = 2 + 2x
 6 + 12 - 6x = 2 + 2x
 18 - 6x = 2 + 2x
 + 6x + 6x
 18 = 2 + 8x
 - 2 - 2 
 16 = 8x
 8 8
 2 = x
The answer is D.

ALGEBRA by bundling cellular land line high speed internet connection and cable service Joyce abbot was able to save 48.50 per m

andreyandreev [35.5K]

Answer: She should budget $672.89 monthly next year for this service.

Step-by-step explanation:

Since we have given that

Amount he was able to save per month = $48.50

Total amount he spent for the year = $1254.89

Amount he saved for the year would be

$48.50\times 12\\\\=\$582$

Amount left from total would be

$1254.89-582\\\\=\$672.89$

Hence, She should budget $672.89 monthly next year for this service.

WRITE DOWN THE FALUE OF 7

Maru [420]

Answer:

(I need to know where the seven is located/placed.) Please give a clear answer or attach a photo next time so everybody who sees your question will understand.

Step-by-step explanation:

Comparing the numbers 700, 70, and 7; the digit "7" has a different value depending on its place within the number.

7 - ones place

70 - tens place

700 - hundreds place

The place value of the 7 determines the value it holds for the number. As the place moves to the left, the value of the number becomes greater by 10 times

(3/5)^2+4X3-2 what is the value of the expression

Sliva [168]

Answer:

10.36

Step-by-step explanation:

So your solution would be:

$(\frac{3}{5})^{2} + 4 \times 3 - 2$

$=(\frac{3}{5})^{2} + 4 \times 3 - 2$

$=\dfrac{3^{2}}{5^{2}} + 4 \times 3 - 2$

$=\dfrac{9}{25} + 4 \times 3 - 2$

$=0.36 + 4 \times 3 - 2$

$=0.36 + 12 - 2$

$=12.36 - 2$

$=10.36$

Just try to remember PEMDAS.

Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.

This is the order we follow when going about expressions with many operations.

Let's start with the parenthesis part. Notice that there is an exponent beside the parenthesis enclosing the fraction. Here we use the quotient to a power rule. We distribute the exponent to the numerator and the denominator.

$=(\frac{3}{5})^{2} + 4 \times 3 - 2\\$

$=\dfrac{3^{2}}{5^{2}} + 4 \times 3 - 2$

$=\dfrac{9}{25} + 4 \times 3 - 2$

Now that we got the parenthesis and exponent out of the way, let's move on to the next. Multiplication/Division. Whichever comes first, you do it first.

We have a fraction so we do that first. Then we do the multiplication after.

$=0.36 + 4 \times 3 - 2$

$=0.36 + 12 - 2$

Next we do the addition/subtraction. Again, whichever comes first.

$=12.36 - 2$

$=10.36$
