Found out g<br> 2(g - 15) = -26 <br> Please help
posledela

Answer: g=2

Step-by-step explanation:

To solve this exercise you need to remember the following properties:

1. The Distributive property states that:

a(b+c)=ab+ac\\\\a(b-c)=ab-ac

2. The Addition property of Equality statest that:

If a=b, then a+c=b+c

3. The Subtraction property of Equality statest that:

If a=b, then a-c=b-c

4. The Division property of Equality statest that:

If a=b, then \frac{a}{c}=\frac{b}{c}

5. The Multiplication property of Equality statest that:

If a=b, then a*c=b*c

Given the equation:

2(g - 15) = -26

You must solve for "g" in order to find its value:

- Apply the Distributive property:

2g - 30= -26

- Apply the Addition property of Equality adding 30 to both sides of the equation:

2g - 30+30= -26+30\\\\2g=4

- Apply the  Division property of Equality dividing both sides by 2:

\frac{2g}{2}=\frac{4}{2}\\\\g=2

Last year, the volleyball team paid $5 pair for socks and $17 per pair for shorts on a total purchase of $315. This year they sp
vivado [14]

Answer:

Option E is correct.

12 pairs of socks and 15 pairs of shorts did team buy each year.

Step-by-step explanation:

Let the number of pairs of socks be x and the number pairs of shorts be y.

As per the statement:

Last year, the volleyball team paid $5 pair for socks and $17 per pair for shorts on a total purchase of $315.

⇒5x+17y = 315                   .....[1]

It is also given that: This year they spent $342 to buy the same number of socks and shorts, because the socks now cost $6 a pair and the shorts cost $18.

⇒6x + 18y = 342                   .....[2]

Multiply equation [1] by 6 both sides we get;

30x+102y = 1890                 .......[3]

Multiply equation [2] by 5 both sides we get;

30x +90y = 1710                   .....[4]

Subtract equation [4] from [3] we get;

12y =180

Divide both sides by 168 we get;

y = 15

Substitute the given values of y =15 in [1] we get;

5x+17(15) = 315

5x + 255 = 315

Subtract 255 from both sides we get;

5x = 60

Divide both sides by 5 we get;

x = 12

Therefore, 12 pairs of socks and 15 pairs of shorts did team buy each year.
