21 ounces to pounds as a mixed number

Answer:

Test A: 40 words per minute

Test B: 54 words per minute

Test C: 44 words per minute

Test B has the highest unit rate

Step-by-step explanation:

Test A divide 30 by [tex]\frac{3}{4}[/tex] (30/0.75=40)

Test B divide 78 by [tex]1\frac{1}{2}[/tex] (78/1.5=52)

Test C divide 99 by [tex]2\frac{1}{4}[/tex] (99/2.25=44)

Hope this helps :-)

Answer:

5/7 is grater than 2/8

Step-by-step explanation:

5/7 = 0.714

2/8 = 0.25

therefore 5/7 is grater than 2/8

Answer:

928

Step-by-step explanation:

Ratio of boys to girls is 9:7, so boys are 9/(9+7) = 9/16 of the total, and the girls are 7/16

the difference is 9/16-7/16 = 2/16 = 1/8, so

x * 1/8 = 116

x = 116*8 = 928

Answer:

Area = 40 cm²

Step-by-step explanation:

Area of triangle is derived by the formula,

Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

Length of Base = 8 cm

Height of the triangle = 10 cm

Therefore, area of the given triangle = [tex]\frac{1}{2}(8)(10)[/tex]

                                                             = 40 cm²

Answer:

3.75 hours

Step-by-step explanation:

Bob completes his homework in 2.5 hours.

In 1 hour, he completes 1/2.5 of his homework.

Joe completes his homework in x hours.

In 1 hour, he completes 1/x of his homework.

Together, they complete the homework in 1.5 hours.

In 1 hour, they do 1/1.5 of the homework.

1/2.5 + 1/x = 1/1.5

Convert the decimal numbers in the numerators into fractions.

1/(5/2) + 1/x = 1/(3/2)

2/5 + 1/x = 2/3

Multiply both sides by the LCD, 15x.

6x + 15 = 10x

-4x = -15

x = 3.75

Answer: 3.75 hours

Answer:

y= -x - 8

Step-by-step explanation:

To write an equation in slope-intercept form, we naturally need both the slope and the y-intercept. Here, our y-intercept is -8, and our slope is -1. The general form of a line in slope intercept form is y = mx + b, where m is the slope and b is the y intercept. Using our values of m = -1 and b = -8 then gives us the equation y = -x - 8.

Step-by-step explanation:

x= 9? sorry if that's wrong

Answer:

x =9

Step-by-step explanation:

take off the x

add 5+3=8

divide 72 by 8

answer is 9 so x=9

you can double check by multiplying 5×9 then 3×9 then adding your answers together to give you 72

Answer:

  $7.14

Step-by-step explanation:

Let p, d, q represent the numbers of pennies, dimes, and quarters in the collection, respectively.

  p + d + q = 45 . . . . . . . . there are 45 coins in the collection

  2p +5 = q . . . . . . . . . . . . 5 more than twice the number of pennies

  p + 4 = d . . . . . . . . . . . . . 4 more than the number of pennies

Substituting the last two equations into the first gives ...

  p +(p +4) +(2p +5) = 45

  4p = 36 . . . . . . . . . . . . . subtract 9

  p = 9 . . . . . . . . . . . divide by 4

  d = 9 +4 = 13

  q = 2(9) +5 = 23

The value of the collection is ...

  23(0.25) +13(0.10) +9(0.01) = 5.75 +1.30 +0.09 = 7.14

The coin collection is worth $7.14.

Answer & Step-by-step explanation:

number of Dave's coins = number of Zack's coins + 5

The question is asking to find the difference in prices paid (thus "more"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.

Answer:

5.34 pages/h

Step-by-step explanation:

4/45 = p/60

p ≈ 5.34

Answer:

Step-by-step explanation:

3/4 of an hour is the same as 0.75

Write a proportion.

4 (pages)/0.75 (hours)=p(pages)/1 hour

Cross multiply and divide

(4x1)÷0.75=5.33 (rounded to the nearest hundred)

p=5.33

Marcia can type 5.33 pages per hour.

Answer:

Answer:y=2x−3+5

Step-by-step explanation:

Answer:

n-5

Step-by-step explanation:

Answer:

2x-3x=24____eqn 1

3x+4y=2____eqn 2

solve eqn 1 and 2 simultaneously using elimination method

eliminate x use the coefficients of x in the two equations to multiply each other i.e

3(2x-3y=24)

2(3x+4y=2)

6x-9y=72

6x+8y=4

eliminate x using the subtraction sign(-)

6x-6x-9y-(+8y)=72-4

-9y-8y=68

-17y=68

divide both side by the coefficient of y

y=68/-17

y=-4

put y=-4 in eqn 2

3x+4y=2

3x+4(-4)=2

3x-16=2

collect like term

3x=2+16

3x=18

divide both side by the coefficient of x

x=18/3

x=6

since we're asked to find x-y

6-(-4)

6+4=10
