Answer:

$1.34

Step-by-step explanation:

He bought a bag of popcorn for $1.68 and a 15-pack of juice bottles.

The total cost before tax was $21.78.

Let the number of juice bottles = x

Hence, our Equation is given as:

$1.68 + 15 × x = $21.78

$1.68 + 15x = $21.78

Collect like terms

15x = $21.78 - $1.68

15x = $20.1

x = $20.1/15

x = $1.34

Therefore, the cost for each bottle of juice = $1.34

The solution to the system of equations is:

[tex]x=10,\:y=4[/tex]

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}5x-4y=34\\ -x+8y=22\end{bmatrix}[/tex]

Multiply -x+8y=22 by 5:  -5x+40y=110

[tex]\begin{bmatrix}5x-4y=34\\ -5x+40y=110\end{bmatrix}[/tex]

so adding the equations

[tex]-5x+40y=110[/tex]

[tex]+[/tex]

[tex]\underline{5x-4y=34}[/tex]

[tex]36y=144[/tex]

solve 36y = 144 for y:

[tex]36y=144[/tex]

divide both sides by 36

[tex]\frac{36y}{36}=\frac{144}{36}[/tex]

Simplify

[tex]y=4[/tex]

For 5x-4y=34 plug in y=4

[tex]5x-4\cdot \:4=34[/tex]

[tex]5x-16=34[/tex]

Add 16 to both sides

[tex]5x-16+16=34+16[/tex]

Simplify

[tex]5x=50[/tex]

Divide both sides by 5

[tex]\frac{5x}{5}=\frac{50}{5}[/tex]

Simplify

[tex]x=10[/tex]

Therefore, the solution to the system of equations is:

[tex]x=10,\:y=4[/tex]

Answer:

Step-by-step explanation:

1.24 * 0.15 = 0.0186

As you can see, the numbers are the same, but the order of the decimal is different.

Since the order of the decimal is different, so will the answer.

1,860 and 0.0186 do have the same numbers in them, but since the decimal is located in different spots, then the answer will be different with different values.

You might not see the decimal in 1,860, but it is after the 0.....

1,860.0 ( same thing just added a decimal, but it is the same value)

Step-by-step explanation:

0 is greater than -18

Answer:

$70

Step-by-step explanation:

According to the problem, calculation of given data are as follows:

Spending money at rate = $5 per day

After 9 days money left = $25

We can calculate the money on day 0 by using following formula,

y = mx + b

Here, y = money left after 9 days

m = rate of spending money

x = number of days

b = money on day 0

So, by putting value, we get

$25 = (-5 × 9 ) + b

b = $25 + $45

= $70

Answer:

[tex]\mathbf{ \dfrac{1}{8} \ box}[/tex]

Step-by-step explanation:

Given that:

Steve divided 5/8 of a box evenly among 5 bottles. To determine the amount of baking soda added;

Then, mathematically:

[tex]=\dfrac{5}{8} \ box \div 5[/tex]

[tex]= \dfrac{5}{8} \ box \times \dfrac{1}{5}[/tex]

[tex]\mathbf{= \dfrac{1}{8} \ box}[/tex]

Answer:

The area of this rectangle is 10cm2, find the value of x and use it to find the length and the width of the rectangle.

If the length of a rectangle is three time the width and it’s perimeter is 24 cm, what is its area?

Length and width of the rectangle are 4 cm and 2.5 cm respectively.

Given in the picture,

        (4x + 2) cm and (10x - 1) cm

By the property of a rectangle, measure of opposite sides of a rectangle are always equal,

(4x + 2) = (10x - 1)

(4x + 2) - 4x = (10x - 1) - 4x

2 = 6x - 1

2 + 1 = (6x - 1) + 1

3 = 6x

[tex]x=\frac{3}{6}=\frac{1}{2}[/tex]

Now we can get the length of the given rectangle by substituting the value of 'x' in (10x - 1) or (4x + 2).

(10x - 1) = [tex]\frac{10}{2}-1[/tex]

            = 4 cm

Since, area of a rectangle is given by the expression,

Area = Length × width

By substituting the values in the expression,

10 = 4 × width

Width = [tex]\frac{10}{4}[/tex]

           = 2.5 cm

        Therefore, length and width of the rectangle are 4 cm and 2.5 cm respectively.

Answer:

18 oranges

Step-by-step explanation:

To find this, we have to calculate 2/5 * 45, which is equal to 45 * 2 and then divided by 5 (Or you could cross cancel). 45 * 2 is equal to 90 and 90/5 is equal to 18. That means that 18 oranges fell out of the tree.
