Step-by-step explanation:

The unit price for the strawberries is:

= 1.5 / 2

= $0.75 per pound

Graph B is the right graph as it uses a unit price of $0.75 per pound for strawberry price. This is why it has points of the graph that mirror the friends purchases such as (2, 1.5) , (3, 2.5) and (4, 3).

[tex]f( - 1) = - 1[/tex]

Step-by-step explanation:

[tex]f(x) = {x}^{2} + 2x[/tex]

Substitute x = -1 in the equation.

[tex]f( - 1) = {( - 1)}^{2} + 2( - 1) \\ f( - 1) = 1 - 2 \\ f( - 1) = - 1[/tex]

Answer:

88 at least

Step-by-step explanation:

So, if you need to give each student a slice remainders round up to the nearest whole number. So first you simply divide 700/8 (Students/Pieces of pizza per slice) and get 87.5. Then you round up to 88 since you cannot buy half a pizza (that's weird). You will have 4 extra slices to feed the teachers btw.

Answer:

$2

Step-by-step explanation:

First, we find the total he spent on the three pencils.

$24 - $18 = $6

He spent $6 on the 3 pencils.

Now we find how much each pencil cost.

$6/3 = $2

Answer: $2

Answer:

Each pencil cost 2$

First I did what he has to spend 24 then subtracted 18 from it what he had left that gave me 6. Next knew that he had bought three pencils so I did 6 divided by 3 and that left me with an answer of 2 so 2$

Step-by-step explanation:

Answer:

He can build 3 toys in 4 minutes.

Step-by-step explanation:

Divide 360 by 8 since you are dividing it first to get the number of toys he can build in an hour.  As a result, he can build 45 toys in an hour.  Divide that number by 15 since 4 times that number equals an hour.  You should get 3 toys as your final result.  

For easier explanation, multiply 8 and 15 together to get 120 for better understanding.  Divide that number from 360 to get the same answer.

The absolute value equation can be used to calculate Jack's maximum and minimum time to fold his laundry is, |x−30|=10. So, Option A is correct

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Given that,

On average, Jack can fold his laundry in 30 minutes

How much laundry he has, his time can vary from the average by 10 minutes

So, maximum time can be 40 minutes

And minimum time can be 20 minutes

Therefore, The result is  |x-30| =10

Step-by-step explanation:

Answer:

125 is 30% of the number 24, hope this helps

Step-by-step explanation:

We have, 125% × x = 30

or, 125/100 × x = 30

Multiplying both sides by 100 and dividing both sides by 125,

we have x = 30 × 100/125

So your answer is X=24
