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.

Find the value of x
(8x-1) (4x+7)

Answers

Answer:

The value of x = 7

Step-by-step explanation:

Given the right triangle

Right angle = 90°α = (4x+7)°β =  (8x-1)°

We know that the sum of angles of a triangle is 180°.

so

Right angle + α + β =  180°

90° + 4x+7 + 8x-1 = 180

Group like terms

[tex]4x+8x+90+7-1=180[/tex]

Add similar elements: :4x+8x=12x

[tex]12x+90+7-1=180[/tex]

[tex]12x+96=180[/tex]

[tex]12x=84[/tex]

Divide both sides by 12

[tex]\frac{12x}{12}=\frac{84}{12}[/tex]

[tex]x = 7[/tex]

Therefore, the value of x = 7

Answers

Answer:

336

Step-by-step explanation:

Using arithmetic operation, the number of oak trees on the land which is of identical habitat would be 336.

Using the relation:

5 acres = 42 trees - - - - - (1)

40 acres = t - - - - - (2)

Cross multiply

5t = 42 × 40

5t = 1680

t = 1680 / 5

t = 336 oak trees

Therefore, the Number of oak trees would be 336

Write how u solved it

Answers

Answer:

0.3

Step-by-step explanation:

Answer:

3.0

Step-by-step explanation:

Here we have a rectangle split into ten parts with 7/10 shaded in blue. The question asks what decimal represents the portion, alright, let's go down the list.

0.003 is also known as 3 thousandths, meaning that we would need a thousand little squares as our figure. Clearly this isn't the case, so 0.003 is wrong.

0.03 is also known as 3 hundredths, meaning  that we would need a hundred little squares as our figure, this also isn't the case, so 0.03 is wrong.

0.3 is known as 3 tenths, yes this could represent our figure, but it doesn't represent the finished portion, which would be 1.0, this means that only one part will be shaded in the figure we have now, leaving it to be wrong.

This leaves us with 3.0

Answer:

It is clear from the graph,

The value of x=-6 at y=0.

Thus, x=-6 is the zero of g.

Step-by-step explanation:

A zero of the linear function 'g' on the graph of a linear function can be observed where the 'y-value' is zero.

In other words,

A point where the line tends to cross the x-axis is called the x-intercept.x-intercept can be observed by setting the y=0 and determining the value of x at y=0

It is clear from the graph,

The value of x=-6 at y=0.

Thus, x=-6 is the zero of g.

Answers

6x + 5 = 4x + 5
2x + 5 = 5
2x = 0, x = 0
Y = 6(0) + 5, y = 5
Solution: x = 0, y = 5

Answer:

y=6x+5  →equation 1

y=4x+5 → equation 2

you can either substitute equation 1 in 2 or equation 2 in 1

substituting equation 1 in 2,

y = 4x + 5

6x + 5 = 4x + 5

6x - 4x = 5 - 5

2x = 0

x = 0/2

x = 0

substituting x = 0 in equation 1, (to get y)

y = 6x + 5

y = 6(0) + 5

y = 0 + 5

y = 5
