Answer:

114

Step-by-step explanation:

9 + 7 = 16

24 - 16 = 8 students on inline skates

8 x 4 wheels per skate = 32

32 x 2 shoes per person = 64

7 x 2 wheels per bike = 14

9 x 4 wheels per skate board = 36

36 + 14 + 64 = 114

What is the solution to the system of equations?<br><br> 5x + 4y = 8 <br> x - 2y = 10
romanna [79]
Double the second equation (multiply by 2)...
2(x-2y=10)
2x-4y=20

Bring in the second equation and add the equations:
(2x-4y=20)
+ (5x+4y=8)

7x=28
x=4

Plug in x into one of the equations to get y...
(4)-2y=10
-2y=6
y=-3

(6,-3)

Mara carried water bottles to the field to share with her team at halftime. The water bottles weighed a total of 60x2 + 48x + 24
ludmilkaskok [199]

For this case we have the following polynomial:

60x ^ 2 + 48x + 24

What we must do for this case is to factor the polynomial, so that we have:

1) The number of bottles

2) the weight of each bottle.

We have then:

12 (5x ^ 2 + 4x + 2)

Answer:

A factorization that could represent the number of water bottles and weight of each water bottle is:

12 (5x ^ 2 + 4x + 2)

Sydney bought a 4-pound bag of brown rice at the grocery store. The nutritional information showed that the bag
FromTheMoon [43]

Answer:

1.72973 oz/serving.  Perhaps round to 1.73 oz, although there is only 1 sig fig in "4-pound bag."  But the problem states "exactly."

Step-by-step explanation:

We want oz/serving, so let's convert the pounds of rice to total ounces of rice:

We are told that 16 oz = 1 pound.  Make that a conversion factor:  (16 oz/1 pound)

(4 pounds)*((16 oz/1 pound) = 64 ounces

We are told that 4 pounds (64 ounces) makes 37 servings.  So:

(64 ounces)/(37 servings) = 1.72973 oz/serving
