Answer:

x = 55

Step-by-step explanation:

To find the value of x

3x - 35 = 130 (vertically opposite angles are equal)

3x = 130 +35

3x = 165

x = 165/3

x = 55

Answer:

x= 55

Step-by-step explanation:

3x-35=130

3x=130+35

3x= 165

x=165/3

x=55

Step-by-step explanation:

-9 + 7 = -2

7 - n = ?

Well the letter "N" could be of any value ( number ) therefore, no they are not the same.

Example:

IF -9 + 7 = -2 IS...

IF N = 1.

IS 7 - 1 equal to -9 + 7? No, because 7-1 = 6 and -9 + 7 = -2

IF N = 2.

IS 7 - 2 equal to -9 + 7? No, because 7 - 2 = 5 and -9 + 7 = -2

and so on...

However:

-9 + 7 and 7 - 9 are the same. I'm pretty sure it's the commutative property.

Average rate of change (Speed) is 8.8 miles per hour

Given:

Distance cover by bike = 22 miles

Time taken to cover distance = 2 hours and 30 minutes

Find:

Average rate of change (Speed)

Computation:

Time taken to cover distance = 2 + 30/60

Time taken to cover distance = 2 + 0.5

Time taken to cover distance = 2.5 hours

Average rate of change (Speed) = Distance cover by bike / Time taken to cover distance

Average rate of change (Speed) = [tex]\frac{22}{2.5}[/tex]

Average rate of change (Speed) = 8.8 miles per hour

Answer:

  2.5 years

  $736 in interest

Step-by-step explanation:

The relationship between the values in an amortization is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

Here, we have A = 140, P = 3400, r = 0.16 and we want to find t

  140 = 3400(0.16/12)/(1 -(1 +0.16/12)^(-12t))

  1 -(1 +0.16/12)^(-12t) = 1/3.0882353

  (1 +0.16/12)^(-12t) = 0.67619048

Taking logarithms gives ...

  -12t·log(1 +0.16/12) = log(0.67619048)

  t = log(0.67619048)/(-12·log(1+0.16/12)) ≈ 2.46177

It will take about 2.5 years to pay off the loan.

__

The total of payments is ...

  (2.46177)(12)($140) = $4135.77

so, the interest paid is ...

  $4135.77 -3400 = $735.77

You will pay about $736 in interest over the life of the loan.

_____

Additional comment

The number of payments is calculated to be about 29.54. You would probably make 30 payments, with the last payment being a different amount than $140. The actual amount will depend on when the payment is made, and the amount of it that is finance charge. We believe the remaining balance after 29 payments will be $75. After a full month, the finance charge due on that amount is $1.00, bringing the total amount of interest paid to $736.

If the loan is paid off in the middle of the month, the interest due is reduced. Above, we have calculated interest based on a last payment made part way through the month. We rounded up, partly because of the ambiguity in the final payment.

Answer:

Im pretty sure its 1. Not 100% sure but im 99.99% sure

Step-by-step explanation:

Answer:

BC = 35in.

Step-by-step explanation:

AD says the entire line is 53in.

AB says it is equal to CD.

CD says it equals 9in so AB + CD = 18in.

BC says it equals 5x.

AB+BC+CD = AD

(9) + (5x) + (9) = 53

5x + 18 = 53

Subtract 18 from both sides

5x = 35

We can stop here because we know that BC = 5x and 5x = 35in.

Answer:

They are similar.

Step-by-step explanation:

123 + 36 + x = 180

159 + x = 180

(159 - 159) + x = 180 - 159

x = 21

36 + 21 + x = 180

57 + x = 180

(57 - 57) + x = 180 - 57

x = 123

CDE = 123 + 36 + 21

ABC = 123 + 36 + 21

Answer:

  t = 4

Step-by-step explanation:

It can be useful to convert the numbers to ratios of integers.

  0.0625 = (0.5)^t

  1/16 = (1/2)^t

  1/2^4 = 1/2^t

  4 = t . . . . . . . match exponents

__

If you like, you can solve this using logarithms.

  0.0625 = 0.5^t

  log(0.0625) = t×log(0.5)

  t = log(0.0625)/log(0.5)

  t = 4
