HELP ME PLEASEEE!!!!!!! I am stuck

Mathematics
1 answer:
NISA [10]3 years ago

Answer:

X = 62

Step-by-step explanation:

The inside of a triangle is always equal to 180º therefore, you need to add everything up to equal 180. It should look like

(x + 1) + 55 + x = 180

Now you just solve.

Since there are 2 x's you can combine the like terms making them equal 2x

Now the equation should look like 2x + 1 + 55 = 180

Simplify the other like terms: 2x + 56 = 180

Now you want to get x by itself so you subtract 56 from both sides:

2x + 56 = 180

    -56      -56

------------------------

2x = 124

Now to finish getting x by itself, divide both sides by 2.

2x = 124

-----   ------

2         2

x = 62

FINALLY you plug in x to see if it worked.

(62 + 1) + 55 + 62 = 180

Gracie earns $7 for each car she washes. she always saves $25 of her weekly earnings. this week, she wants to have at least $65
nata0808 [166]
65 divided by 7 is approximently 9, and 25 divided by 7 is approximently 3, so 9 plus 3 is 12, so Gracie must wash 12 cars to earn enough money to save 25 and spend 65!

A house was valued at $100,000 in the year 1987. The value appreciated to $165,000 by the year 2002.
iris [78.8K]

Answer:

  A) The annual multiplier was 1.0339; the annual increase was 0.0339 of the value.

  B) 3.39% per year

  C) $182,000

Step-by-step explanation:

A) Let's let t represent years since 1987. Then we can fill in the numbers and solve for r.

  165000 = 100000(1 +r)^15

  1.65^(1/15) = 1 +r . . . . . divide by 100,000; take the 15th root

  1.03394855265 -1 = r ≈ 0.0339

The value was multiplied by about 1.0339 each year.

__

B) The value increased by about 3.39% per year.

__

C) S = $100,000(1.03394855265)^18 ≈ $182,000
