Dillon pays x dollars to get a haircut. He gives the stylist a
25% tip. The expression representing his total cost is
x + 0.25x

Which expression is equivalent and why?

A. 1.025x because adding 25% to the cost of the haircut is the same
as multiplying the cost by 1.025.

B. 1.25x because adding 25% to the cost of the haircut is the same
as multiplying the cost by 1.25.

C. 1.25x because adding $25 to the haircut is the same as
multiplying the cost by 1.25.

D. x(0.25) because the cost of the haircut can be factored out.

Answers

Answer:

B

Step-by-step explanation:

the percentage of money to be paid is 125% which is equivalent to 1.25 in fraction

The equivalent expression is" 1.25x because adding 25% to the cost of the haircut is the same as multiplying the cost by 1.25. Option B is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that, Dillon pays x dollars to get a haircut. He gives the stylist a 25% tip. The expression representing his total cost is,x + 0.25x

Expressions that function identically while having distinct appearances are called equivalent expressions. If two algebraic expressions are equivalent, then they both have the same result when the same value of the variable is entered.

=x + 0.25x

=1.25x

Thus, the equivalent expression is" 1.25x because adding 25% to the cost of the haircut is the same as multiplying the cost by 1.25. Option B is correct.

blake is saving up on a new pair of headphones. He has $20 saved already, and he earns $10 for every lawn he mows. How many lawns will he have to mow to have at least $90 saved . What is the inequality and the solution?

Answers

Answer: 20× + 10 < 90

Step-by-step explanation:

Blake will have to mow at least 7 lawns to have at least $90 saved.

The inequality is: 20 + 10x ≥ 90

The solution is: x ≥ 7

What is inequality?

Inequality is a mathematical statement that compares two values, expressing that one value is less than, greater than, less than or equal to, greater than or equal to, or not equal to another value.

Inequalities are commonly represented using symbols such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).

Let's assume Blake has to mow x lawns to have at least $90 saved.

Since he earns $10 for every lawn he mows, the amount he will earn by mowing x lawns is 10x.

Adding his initial savings of $20 to the amount he will earn from mowing lawns gives us the following inequality:

20 + 10x ≥ 90

Subtracting 20 from both sides:

10x ≥ 70

Dividing both sides by 10:

x ≥ 7

Therefore, Blake will have to mow at least 7 lawns to have at least $90 saved.

The inequality is: 20 + 10x ≥ 90

The solution is: x ≥ 7

Solve the following equation for x give your answer in simplified form 1/4x +3y =8

Answers

x= 2 - 3/4y. if you do the equation, you would start by subtracting 3y from both sides. now you would have 1/4x= 8-3y. then you would divide both sides by 4, to get x= 2-3/4y.
