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

Emilio 4(h−2)

Answers

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.

In order to find the solution, You would first line line the equation up. then, you would subtract -200 by 15. The answer would be -185. I know the answer will be negative because -200 is too big for 15 to make the solution positive. If you had a positive 201 plus -200 the answer would be equivalent to a positive one because the positive would cancel out the negative.

Included: Negative, positive, equivalent.

explanation/ statement:

"I think I should subtract -200 by 15. which one equal -185. I know the answer will be negative because -200 is too big for 15 to make the solution positive.

The government argued that the Commerce Clause, which gives Congress the power to regulate commerce with foreign nations, and among the several states, gave lawmakers appropriate constitutional power. The government said that guns in school zones led to violent crime which could affect commerce by causing insurance rates to rise and discouraging travel through unsafe areas. Contrary to the governments argument, however the power to establish and maintain schools is traditionally reserved for the states. Many states, in turn, pass this responsibility on to local governments. Although Congress has substantial experience in creating firearms legislation, it does not have knowledge about, or experience managing, any one particular school district. States also have the power to provide fire and police protection. Which expressed, concurrent and reserved powers apply to this issue?
