please HELP MEEEEEE .A store owner wants to make a candy that sells for $1 per pound.he has 50 lb of sugar candies that cost $1.20 per pound.how many pounds of gummy candies that cost 80 cents per pound should he add.

Answers

Answer:

50 pounds

Step-by-step explanation:

we can use the equation           60+80/100x=1(x+50)

we get 80/100 x because the gummy candies are 80 cents or 80/100x

we get 60 from multiplying 1.20$ x 50 = 60

                                                    solve:

                        60+80/100x  =  x+50

                           60 = x-80/100x+50

                             60-50 = 20/100x

                              10 = 20/100x

                               x= 10 x 100/20 = 10x5= 50 pounds

Using proportions, it is found that he should add 50 pounds of gummy candies that cost 80 cents per pound.

What is a proportion?

A proportion is a fraction of a total amount.

This problem is organized as follows:

There is a total of 50 + x pounds.Of those, 50 cost $1.2 per pound.x cost $0.8 per pound.The selling price is of $1.

Hence:

[tex]\frac{50}{50 + x}1.2 + \frac{x}{50+x}0.8 = 1[/tex]

[tex]\frac{60 + 0.8x}{50 + x} = 1[/tex]

[tex]50 + x = 60 + 0.8x[/tex]

[tex]0.2x = 10[/tex]

[tex]x = \frac{10}{0.2}[/tex]

[tex]x = 50[/tex]

He should add 50 pounds of gummy candies that cost 80 cents per pound.

Answer:

x=12,  SV=30

Step-by-step explanation:

Since <S is congruent to <T, you know that line TV is equal to line SV

2x+6=3x-6

subtract 2x on both sides

6=x-6

add 6 to both sides

12=x

x=12

To find SV you need to plug in x

Boris rented a truck for one day. There was a base fee of $16.95, and there was an additional charge of 89 cents for each mile driven. Boris had to pay $131.76
when he returned the truck. For how many miles did he drive the truck?

Answers

Boris drove the truck 129 miles. You take how much the base fee (16.95) and subtract it from the total of how much he had to pay (131.79). The problem would look like $131.79 - $16.95 = $114.84. Then would would take 114.84 and divide it by the cost of one mile. This problem would look like $114.84 divided by $0.89 = 129. This means the driver drove 129 miles! I hope this helps!

snows 3 inches in 6 hours

i

Answer:

18

Step-by-step explanation:

3 inches for every 6 hours. There are 6 6-hour groups in 36, so to find the inches in 36 hours, we would multiply the 3 inches times the 6 groups of 6-hour increments (aka 3*6). 3*6 = 18, so after 36 hours of snowing, we'd end up with 18 inches of snow.
