solve 8p = 40 using mental math

A 32 B6 C 5 D 4

Answer:

Part 1;

10y + 4x ≤ 96

Part 2;

y = 8

x = 4

Step-by-step explanation:

1 - Write an equation

Let z equal the total price

10y + 4x = z

2 - Use that to answer the questions

"Write an inequality to represent the different possible combinations that Andy can buy if he has $96."

If Andy has $96 that means the amount the two add up two can equal 96 or be less than 96 however not any more. That means 10y + 4x must be less than or equal to 96. This is written as follows

10y + 4x ≤ 96

With this in mind we can answer the following question of what is one possible combination. To do this, lets assume

10y + 4x must equal 96

Lets make 96 divisible by 10 using our pounds of roast beef.

To do this we need to get rid of the 6; which we can do so by turning 4x into 16. 4 goes into 16 4 times.

Therefore;

10y + 4x = 96

10y + 4(4) = 96

10y + 16 = 96

      - 16   - 16

10y= 80

Divide both sides by 10

y = 8

And our x when y = 8 was 4

so

x = 4

Answer:

The probability that the next spin will land on blue is 0.12.

Step-by-step explanation:

The result of the several spins are as follows:

Color           Frequency

Red                  18

Blue                   9

Green               18

Yellow              19

Purple               12

TOTAL             76

Compute the probability that the next spin will land on blue as follows:

[tex]P(Blue)=\frac{n(Blue)}{N}\\\\=\frac{9}{76}\\\\=0.1184211\\\\\approx 0.12[/tex]

Thus, the probability that the next spin will land on blue is 0.12.

The probability that the next spin will land on blue as a decimal to the nearest hundredth is 0.12 and this can be determined by using the given data.

Given :

A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow, and purple.

The spinner is spun several times, and the results are recorded below:

Colour                               Frequency

Red                                         18

Blue                                         9

Green                                      18

Yellow                                     19

Purple                                      12

So, the total frequency is = 18 + 9 + 18 + 19 + 12

                                          =  76

Based on the above given results, the probability that the next spin will land on blue is given by:

[tex]\rm P = \dfrac{n}{N}[/tex]

[tex]\rm P = \dfrac{9}{76}[/tex]

P = 0.1184

P [tex]\approx[/tex] 0.12

So, the probability that the next spin will land on blue as a decimal to the nearest hundredth is 0.12.

Answer:

$25.44

Step-by-step explanation:

To find the markdown, multiply the initial cost of the jeans by the percentage of the initial price the new amount will be. If the jeans are getting a 25% markdown, then the new cost will be 75% of the initial cost. Convert 75% and then multiply it by 32:

32 * 0.75 = 24

Now that we know the price of the jeans, we can calculate the sales tax. Multiply 24 by 0.06 to find the sales tax:

24 * 0.06 = 1.44

Now add the sales tax to the new cost to get your final answer:

1.44 + 24 = 25.44

You will pay $25.44 for the jeans.

Answer:

En una hora, la máquina podría envasar 160 cajas de frascos grandes, o 96 cajas de frascos medianos.

Step-by-step explanation:

Si la maquina solo envasara frascos de un tipo, y pudiese envasar 1920 tarros por hora, para determinar cuantas cajas de frascos grandes envasaría cada hora hay que realizar el siguiente cálculo:

1920 / 12 = X

160 = X

Así, en una hora, la máquina envasaría 160 cajas de frascos grandes.

Por otra parte, en caso de envasar frascos medianos, el cálculo sería el siguiente:

1920 / 20 = X

96 = X

Por ello, la máquina envasaría 96 cajas de frascos medianos en una hora.

Answer:

The monetary choices for Ivy’s lunches is to spend less than $16.67 at restaurants and to spend less than $33.33 on groceries in order to to keep her weekly budget to less than $50.

Step-by-step explanation:

This can be determined as follows

x = the amount of dollars spent at restaurants

y = the amount of dollars spent on groceries

Since Ivy decides that she wants to spend at least twice as much on bagged lunches as at restaurants, we have

y = 2x .................. (1)

Since Ivy wants to keep her weekly budget to less than $50, using the x and y, we have:

x + 2x < 50 ............................ (2)

We can now solve for x as follows:

3x + < 50

x < 50 / 3

x < 16.67

Substituting the x < 17 into equation (1) noting that Ivy wants to keep her weekly budget to less than $50, we have:

y < 2 * 16.67

y < 33.33

Therefore, the monetary choices for Ivy’s lunches is to spend less than $16.67 at restaurants and to spend less than $33.33 on groceries in order to to keep her weekly budget to less than $50.

y = 5x - 6

Step-by-step explanation:

The equation is in the form

y = mx + c ( m is the rate of change and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (3, 9) ← ordered pairs from the table

m = [tex]\frac{9+6}{3-0}[/tex] = [tex]\frac{15}{3}[/tex] = 5

Step-by-step explanation:

Use the equation I=prt, where I is the interest and p is the percentage of simple interest, which is 6% or 0.06. T is the rate of time in years. R is the amount Felix deposited. Our equation would be:

I=(0.06)(1340)(3)

I=(0.18)(1340)

I=$241.20

The result we get when we divide the fractions, 5/8 ÷ 1/4 = D. 2 and one-half.

To divide a fraction by another fraction, simply change the division sign to multiplication sign and turn the fraction on the right of the sign upside down, such that what we have as the denominator of the fraction will now be the numerator while what we have as the numerator of the fraction will now be the denominator.

After doing this, multiply the denominators of the fractions and the numerators of the fractions.

Given the fractional expression, 5/8 ÷ 1/4, to divide, turn the fraction on your right upside down and change the sign to multiplication:

5/8 × 4/1

Multiply the denominators and also multiply the numerators of the fractions:

(5 × 4)/(8 × 1)

= 20/8

Simply further by dividing 20 by 4 and dividing 8 by 4:

4 into 20 is 5.

4 into 8 is: 2

Therefore:

20/8 = 5/2

= 2½

Therefore, 5/8 ÷ 1/4 is: D. 2 and one-half.
