Victoria has $30 to spend at the fair. Admission cost $7. Ride tickets cost $0.75 each.
Write and solve an inequality that represents the number of ride tickets, she can purchase.

Answers

Step-by-step explanation:

30-7=23 dollars remained

let x be the tickets number

so 0.75*x=23

x=23/0.75

x=31 at least.

Find the error and explain what the correct step should be

Answers

Answer:

m = 12, the error was that the student did not divide both sides by -. so they got the incorrect answer

Step-by-step explanation:

okay, so you want to get m

because m is divided by 3, to counter it, you multiply both sides by three

-m/3 = -4

-m/3 times 3 =-4 times 3

because 1/3 times 3 =1, and -4 times 3 = -12, you get

-m = -12

then, divide both sides by - (because you want positive m)

and you get m = 12

the error was that the student did not divide by the negative, so in the end, their sign was wrong.

Step-by-step explanation:

Answer:

Step-by-step explanation:

After 5 minutes, the amount of water that has flowed is ...

Answers

Answer:

For the first section, you write the algebraic expression or equation that goes with the statement.

For example, 9 more than the product of 51 and number "i" would translate into 51i+9. More and sum refers to addition, difference is subtraction, and quotient is division.

For the second section, you just simplify each of the expressions. when a number has ^, that means it has the square root, so 9^2 would be nine squared, which is 81.

For the third section, replace the c values for 3 and the d values for 5.

For the fourth section, determine whether or not each number is rational by writing the number as a fraction where both numerator and denominator are whole numbers. Pi is irrational as it can't be written as the fraction of 2 integers

For the last section, combine like terms and explain each step.

Rena's grandfather opened a savings account as a college fund for her. His initial deposit and the yearly simple interest rate are shown. A college graduate is shown walking up stairs. The bottom step represents three thousand five hundred dollars. The value of the top step is unknown. The distance up the stairs is labeled four years. The simple interest rate is three point two five percent. How much will Rena have in this account after 4 years? Enter the correct answer in the box.

Answers

Answer:

$3,955

Step-by-step explanation:

Given that:

Initial deposit = $3500

Simple rate of interest = $3.25%

Number of years = 4

Simple interest = (principal * rate * time)

Principal = Initial deposit = $3500

Interest = $3500 * 3.25% * 4

Simple Interest = $455

Amount that will be in account after 4 years :

$3500 + $455 =$3955

Answers

Answer:

x = 3, y = 6, z = 4

Step-by-step explanation:

If lines s, t, and u are perpendicular bisectors of the sides of APGH and meet at J, then JG = JH = JF = HI

Given

JG - 2x+ 2

JH - 2y-4

JF-8 a

HI - 3z-3,

Hence 2x+2 = 2y-4 = 3z-3 = 8

This means that

2x+2 = 8

2x = 8-2

2x = 6

x = 3

Also, 2y-4 = 8

2y = 8+4

2y = 12

y = 6

And 3z-3 = 8

3z = 8+3

3z = 11

z = 11/3

z = 3.67 ≈ 4

Hence x = 3, y = 6,z = 4

Students surveyed boys and girls separately to determine which sport was enjoyed the most. After completing the boy survey, it was determined that for every 3 boys who enjoyed soccer, 5 boys enjoyed basketball. The girl survey had a ratio of the number of girls who enjoyed soccer to the number of girls who enjoyed basketball of 7: 1. If the same number of boys and girls were surveyed, and 90 boys enjoy soccer, how many girls enjoy each sport?

Answers

Ratio of boys who liked soccer to boys who liked basketball = 3:5

Given :-

Number of boys who enjoyed soccer :-

[tex]\color{hotpink} = \color{hotpink}90 \: \: \color{hotpink}boys[/tex]

Total number of boys who were surveyed were equal to the total number of girls who were surveyed .

Which means :-

Let the total number of boys who were surveyed be x .

Total number of boys =

[tex] = \frac{3}{8} \times x = 90[/tex]

[tex] = x = 90 \div \frac{3}{8} [/tex]

[tex] = x = 90 \times \frac{8}{3} [/tex]

[tex] = x = \frac{720}{3} [/tex]

[tex]\color{hotpink}x =\color{hotpink} 240[/tex]

Which means a total of 240 boys were surveyed .

Number of boys who liked basketball :-

[tex] = \frac{5}{8} \times 240[/tex]

[tex] = \frac{1200}{8} [/tex]

[tex]\color{hotpink} = 150 \: \: boys[/tex]

Which means a total of 150 boys liked basketball .

Number of girls who liked soccer :-

[tex] = \frac{7}{8} \times 240[/tex]

[tex] = \frac{1680}{8} [/tex]

[tex]\color{hotpink} = 210 \: \: girls[/tex]

A total of 210 girls enjoyed soccer .

Number of girls who enjoyed basketball :-

[tex] = \frac{1}{8} \times 240[/tex]

[tex] = \frac{240}{8} [/tex]

[tex]\color{hotpink} = 30 \: \: girls[/tex]

A total of 30 girls like basketball .

Therefore , 210 girls enjoyed soccer and 30 girls enjoyed basketball .

The third answer, y = 4x + 1

Step-by-step explanation:

Let's take the pair x = 2, and y = 9.

We know what x is, and what the result, y, is now.

Let's plug x into the third equation, y = 4x + 1

y = 4 * 2 + 1

y = 8 + 1

y = 9

We already know that y = 9, so this equation is correct.
