Answer:

38 1/2 meters

Step-by-step explanation:

You have to multiply 28× 1 3/8

You can convert yhe 1 3/8 to an improper fraction, then multiply, and convert back to a mixed number. See image.

OR,

you can distribute the 28 over the sum of 1 and 3/8. This just keeps the fraction a little bit smaller and you can practice distributive property see image

Answer:

see explanation and attachment

Step-by-step explanation:

(1) y = -x + 2

so slope is -1 and y-intercept is (0,2)

(2) 2x - y = 7

y = 2x - 7

so slope is 2 and y-intercept is (0,-7)

Answer:

-5(8) = -40-5(-2x) = -40+10x

The value of an equivalent expression is,

⇒ 10x - 40

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Expression is,

⇒ - 5 (8 - 2x)

Now, We can simplify as;

⇒ - 5 (8 - 2x)

⇒ - 5 × 8 - 5 × - 2x

⇒ - 40 + 10x

⇒ 10x - 40

Thus, The value of an equivalent expression is,

⇒ 10x - 40

Answer:

Answer 4, the bottom right answer

Step-by-step explanation:

Question was pretty blurry so I had to write it out:

The school Spanish Club is holding a car wash to raise $200 to attend a conference. After spending $10 on supplies, the club will was cars for donations of $4 each.

The situation can be modeled by the inequality 4z-10≥200, which has the solution z≥52.5. What is the best way to interpret this solution?

1. At least 53 members of the Spanish Club must volunteer to help at the car wash.

2. The Spanish Club should have spent at least $52.50 on supplies.

3. The Spanish Club needs $52.50 more to meet its goal.

4. The Spanish Club must wash at least 53 cars to meet its goal.

The answer would be 4, because the inequality is saying 4 dollars times the number of cars minus 10 dollars (for supplies) has to be greater than or equal to their goal of 200 dollars they want to raise.

Another way to explain: The 4z would represent how much money they would make for all the cars they wash, but they have to subtract 10 dollars for the supplies. This total has to be equal to or more than their goal of 200 dollars.

Since no equations were provided, the solution of the equation will depend on the values of p.

The solution of an equation is the value that makes that equation true.

Given the equation q = 60 - 4p

The solution of the equation will depend on the value of p

For example; if p = 1

q = 60 - 4(1)

q = 56

Therefore, the solution of the equation will depend on the values of p.

Answer:

3, 6, 11 and 102

Step-by-step explanation:

substitute n = 1, 2, 3, 10 into the nth term rule

a₁ = 1² + 2 = 1 + 2 = 3

a₂ = 2² + 2 = 4 + 2 = 6

a₃ = 3² + 2 = 9 + 2 = 11

a₁₀ = 10² + 2 = 100 + 2 = 102

Step-by-step explanation:

The statement which is true is

total job benefits - total job expenses = total employment compensation.

Costs, expenses, debts, liabilities, and duties related to or incurred in conjunction with work are referred to as job expenses, sometimes known as employment expenses.

The employment benefits provided to the Employee include wages, fees, incentive pay, gratuities, bonuses, vacation pay, holiday pay, other paid time off, overtime pay, standby pay, sick pay, and workers' compensation insurance.

When an employee performs well at work, he is entitled to receive these advantages.

Therefore, the total compensation of the employee is calculated through deducing the total employment benefits to the total job expenses.

Answer:

Alvin's Age is 81 and Elga's age is 27

Step-by-step explanation:

let A be Alvin's age and E be Elga's age

A = 3 E (alvin's age is three times elga's age)

A + E = 108 ( the sum of their ages is 108)

3E + E = 108

4 E = 108

E= 108/4 = 27

A = 3E = 27*3 = 81

⭐ Let the Alvin's age be "a" and the Elga's age be "e".

⭐ If we carefully identify the question, we can get two hints provided in the question which can be framed into equations. They are,

(Alvin's age is 3 times the age of Elga's age)

(The sum of Alvin's and Elga's age is 108)

Substituting value of A i.e (A = 3E) in eqn (2) so as to get same variable and solve the eqn.

[tex]\Rrightarrow\bf{a + e = 108}[/tex]

[tex]\Rrightarrow\bf{3e + e = 108}[/tex]

[tex]\Rrightarrow\bf{4e = 108}[/tex]

[tex]\Rrightarrow\bf{e = \frac{108}{4} }[/tex]

[tex]\Rrightarrow\bf{e = 27}[/tex]

Substituting value of (e = 27) in eqn (1),

[tex]\Rrightarrow\bf{a = 3e}[/tex]

[tex]\Rrightarrow\bf{a = 3 \times 27}[/tex]

[tex]\Rrightarrow\bf{a = 81}[/tex]
