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

What is the solution of an equation?

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

Alvin's age is three times Elga's age. The sum of their ages is 108. What is Elga's age?

Answers

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,

A = 3E ... (1)

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

A + E = 108 ... (2)

(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]

Thus, the age of Alvin is 81 years and that if Elga is 27 years

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.
