Dmitriy789 [7]

Answer

Find out the how many games did the teams lose .

To prove

Formula

Percentage = \frac{Part\ value\times 100}{Total\ values}

As given

Salem High School's winter sports teams WON 72% of their games last season.

If the teams played 50 games .

Percentage = 72%

Total value = 50

Put in the formula

72 = \frac{Number\ of\ games\ win\times 100}{50}

Number\ of\ games\ win = \frac{72\times 50}{100}

Number of games win = 36

Number of  games teams loses = Total number of games - number of games win

                                                          = 50 - 36

                                                          = 14

Therefore the number of games  team loses are 14 .

Elena has 35 magazine subscriptions to sell. Each magazine subscription costs $8.50. Elena sold 17 magazine subscriptions on Fri
KengaRu [80]
Answer : The answer is $153.00 from selling magazine subscriptions on Saturday.

Explanation : We know that each magazine is equal to $8.50. At first she sold 17 of the 35 magazines. 17 x $8.50 = $144.50 from selling 17 magazines. Now we do 35-17 to get how many magazines are left. So there is 18 magazines left. We need to do the same thing we did before, 18 x $8.50 = $153.00. She got $153.00 from selling 18 magazines on Saturday.

How do I do this problem <br> -6(x+1)-18=26+4
pogonyaev

Answer:

x=-9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−6(x+1)−18=26+4

(−6)(x)+(−6)(1)+−18=26+4(Distribute)

−6x+−6+−18=26+4

(−6x)+(−6+−18)=(26+4)(Combine Like Terms)

−6x+−24=30

−6x−24=30

Step 2: Add 24 to both sides.

−6x−24+24=30+24

−6x=54

Step 3: Divide both sides by -6.

−6x

−6

=

54

−6

x=−9

Answer:

x=−9
