y= the total cost

x=the number of cases purchased

Since y is the total it is going to be our ending value so y=12x

Hope this helps!

A football team loses 3 yards on each of 4 consecutive plays. Find the total change in yards from where the team started.

Answers

Answer:

-12

Step-by-step explanation:

If you lose 3 yards for EACH of the 4 plays, than the equation is -3x4=-12

-12, If your loosing 3, it’ll be a negative number. If you loose 3 yard 4 times, it’ll be multiplying -3 • 4 and when multiplying two numbers that have different signs, the product will be negative. So, if you just multiply 3x4 it’ll equal 12. But they have different signs so it’ll be -12. :)

Step-by-step explanation:

Surface area is all the areas of the sides added up. in this case, it would be calculated as follows:

2×8×2.5 = 2 long sides of box = 40

2×6.75×2.5 = 2 short sides of box = 33.75

2×6.75×8 = 2 faces of box = 108

40 + 33.75 + 108 = 181.75

Answer:

Four siblings have a dog walking business. The table shows the hours worked by each sibling. Each sibling earns $25.50 per hour and the total number of hours worked is represented by 10h+15 , where h represents the number of hours Michael worked.

Martin 2.5h+3

Emilio 4(h−2)

Michael h

Mario 31

The algebraic expression is the combination of variable and constants with some mathematical operation between them. The Earning of the four siblings are $357, $244.8, $112.2 and  $790.5 respectively.

What is an Algebraic expression?

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

Given that,

The earning of the siblings per hour is $25.50.

Total number of hours worked is 10h + 15.

As per the problem the value of h can be found by equating the total number of hours to the sum of hours worked by each sibling as given in the table as follows,

2.5h + 3 + 4(h - 2) + h + 31 = 10h + 15

⇒  2.5h + 3 + 4h - 8 + h + 31 = 10h + 15

⇒  7.5h + 26 = 10h + 15

⇒  2.5h = 11

⇒  h = 11 / 2.5

⇒  h = 4.4

Thus, the earning of each sibling can be calculated by substituting h = 4.4 in their working hour and multiplying it by $25.50 as follows,

Earning of Martin is given as,

(2.5 × 4.4 + 3) × $25.50 = $357

Earning of Emilio is given as,

4(4.4 − 2) × $25.50 = $244.8

Earning of Michael is given as,

4.4 × $25.5 = $112.2

Earning of Mario is given as,

31 × $25.50 = $790.5

Hence, the earnings of the four siblings are as Martin :  $357, Emilio : $244.8, Michael : $112.2 and Mario : $790.5.
