Amber and her friend nathan are
saving to buy a video game that costs
$65. amber earns $12 per week for
babysitting and spends $4 of it. nathan
earns $15 per week for walking dogs
and spends $8 of it. which expression
can be used to find how many weeks it
will take to save for the video game?
a 65 = [(12 – 4) + (15 - 8)]
b 65 = [(12 + 4) – (15 + 8)]
© 65 = [(12 - 4) + (15 + 8)]
d 65 = [(12 + 4) - (15 - 8)]

{(12-4) + (15-8)}x  = 65

Step-by-step explanation:

The amount Amber earns per week

12-4

The amount Nathan earns per week

15 -8

The total amount per week they earn together

(12-4) + (15-8)

Multiply by x weeks

{(12-4) + (15-8)}x

Set this equal to 65 to be the amount they need to equal 65 dollars

{(12-4) + (15-8)}x  = 65

{(12-4) + (15-8)}x  = 65

Step-by-step explanation:

Because...

First, you need to know what Amber earns per week : which is,

12-4

Then, Nathan earns per week is :

15 -8

After, the in total that they earned altogether is :

(12-4) + (15-8)

Which you then, Multiply by x weeks

{(12-4) + (15-8)}x

Furthermore, your answer is going to be {(12-4) + (15-8)}x  = 65

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
