Answer:

17 - 42

18 - 50

Step-by-step explanation:

17)

You know the total measurement of both angles is 180.

So your formula is (2x+54) + x = 180. Now rearrange to get

180 - (2x+54) = x or 180-2x+54 =x

Simply to -2x+126 = x followed by moving x and moving 126 to get

-3x = -126 , now divide both sides by -3

18)

Your complete circle is 360 and you know one angle is 90.

Set your formula to 360=90+(3x)+(x-20)+(2x-10)

Rewrite to 360 = 90+3x+x-20+2x-10 and combine like terms

360 = 90 - 20 - 10 + 3x + x+2x

360 = 60 + 6x

360 - 60 = 6x

300 = 6x

300/6 = x

50 = x

Answer:

f(x) is the total cost and x is the number of peaches.

Step-by-step explanation:

We know that each peach costs $0.75. This means the expression 0.75x represents the total cost of peaches; this makes x represent the number of peaches.

We also know that $2.25 is the cost of juice. Adding it to the cost of peaches gives us the total cost; this means f(x) represents the total cost.

a tree casts a shadow 42 feet long.at the same time, a person 5 feet tall casts a shadow 7 feet long. what is the hight of the t

arlik [135]

Answer:

height of the tree is 30 feet

Step-by-step explanation:

a tree casts a shadow 42 feet long . at the same time, a person 5 feet tall casts a shadow 7 feet long.

shadow of a 5 feet tall person is 7 feet long

Let x be the height of the tree

shadow of a 42 feet tree is x feet long

Make a proportion

$\frac{x}{42} =\frac{5}{7}$

cross multiply

$7x=(42)(5)$

$7x=210$

divide by 7 on both sides

x=30

So height of the tree is 30 feet
