Answer:

12a

12a = 96

Step-by-step explanation:

12a + (6a + 8) + (10a - 4) + (6a + 8) = 204

Combine like terms.

34a + 12 = 284

34a + 12 - 12 = 284 - 12

34a = 272

34a ÷ 34 = 272 ÷ 34

a = 8

Let's replace a and see.

6a + 8

6(8) + 8

48 + 8

12a

12(8)

10a - 4

10(8) - 4

80 - 4

An investment of $4000 earns 2% interest compounded annually. What will be the value of the investment in 7 years?

Answers

$4594

a=p(1+r)^t
a=final number
p=principal balance (initial)**without interest**
r=interest rate
t=the amount of time
p=$4000
t= 7yrs
r=2%=0.02
we need to turn 2% into a decimal, to do that you divide 2 by 100 which is 0.02
now we rewrite the equation-
a=4000(1+0.02)^7
a=4000*1.1486

The temperature at 5 p.m. was −4 ∘F. The temperature rose 7 ∘F once the sun came up at 8 a.m. the next morning.

What was the temperature at 8 a.m. that morning?

Answers

Answer:

3 degrees F

Step-by-step explanation:

-4 + 7 = 3

The temperature at 5:00pm was -4°F. The temperature rose (it means adding) 7°F once the sun came up at 8:00am.

Write an addition expression.

(-4)+(+7)

-4+7

(The answer is positive because it matches the sign of 7, the numerically larger number)

Therefore, the temperature was 3°F.

Jada has a monthly budget for her cell phone bill. Last month she spent 120% of her budget, and the bill was $60. What is Jada’s monthly budget? Explain or show your reasoning.

Answers

Assume that the budget is n.
Now we are given that 120% of the budget is equal to $60.
This means that:
60 = 1.2n

Solve the equation for n to know the budget:
60 = 1.2n
n = 60 / 1.2 = 50

Based on the above calculations, Jada's budget is 50$

Jadas budget is 50$ hope this helped

Area of a triangle = 1/2(b)(h)

*b means base and h means height*

Since there are four separate triangles here, we have to find the area for each and add each area together.

1/2(8)(16)

1/2(128)

We can multiple 64 by 2, because there are two triangles of this same size in the kite.

64(2) = 128

1/2(8)(6)

1/2(48)

We can also multiply 24 by two since the kite includes two triangles of this same size.

24(2) = 48

48 + 128 =

If the perimeter is 20 what must be the length of the missing side length? (Answer with Number Only) *

Answers

Answer:

Step-by-step explanation:

Perimeter = Sum of all side lengths

If perimeter = 20, then 5 + 3 + 4 + x = 20

( where x = missing side length )

5 + 3 + 4 = 12

12 + x = 20

20 - 12 = 8

Hence, x = 8

The answer would be 8
Step by step
5+3= 8
8+4=12
20-12=8
