Mathematics
1 answer:
Harlamova29_29 [7]3 years ago
3 0

Answer:

DCB = 84

Step-by-step explanation:

Here, we want to calculate the value of the angle

To do this, we use an important parallelogram angle property

The adjacent sides are supplementary, meaning they add up to 180

We have this as;

180-96 = 84 degrees

I need to know how to solve these using the box method
Basile [38]

Answer:

5. (2x-3)(3x+2)

6.(x-8)(2x-5)

7.(5x-2)(2x+1)

8.(4x+3)(x+3)

Step-by-step explanation:

example on how to solve this in not how you solve your questions

2x times x = 2x2

2x times 2 = 4x

5 times x = 5x

5 times 2 = 10

The factors are (2x + 5)  and (x + 2), so 2x2 + 9x + 10 = (2x + 5) ×  (x + 2)

4x and 5x are interchangeable, so you could put 5x in the first row and 4x in the second row and still get the same answer.

1: What is Abby's total spent on transportation?
stealth61 [152]

Answer:

1. Total spent on transportation $222.2.

2. $ 192.5

3. She spends $30 over the guideline.

Step-by-step explanation:

As per the image attached:

Total monthly spent on transportation = Total monthly car payment + Spent on gas fuel

Total monthly spent on transportation = 120 + 37.9 + 28.4 + 35.9 = $222.2

So, Answer 1. Abby's total spent on transportation = $222.2

Calculating the percentage:

\Rightarrow \dfrac{\text{Spent on transportation}}{\text{Total monthly income}}

\Rightarrow \dfrac{222.2}{1750}\times 100 =12.69\%

Calculating 11% as per the guideline:

1750 \times \dfrac{11}{100}\\\Rightarrow \$192.5

Answer 2. As per the guideline, she should spend $192.5 on transportation.

Difference between spending and guideline = $222.2 - $192.5 = $29.7

Answer 3. She spends $29.7 over the guideline.

Dave has $3000 more in a passbook account than in a money market.
Goryan [66]

The amount in the passbook account is $11,000 and the money in the money market account is $8000

Let:

a represent the unknown amount in the passbook account

b represent the unknown amount in the money market account

From the question, the following information can be gathered:

  • The money in the passbook account exceeds the amount in the money market account.

This information can be represented with this equation : a - b = 3000

  • The interest paid on the passbook account exceeds the interest paid on the money market account.

This information can be represented with this equation : 0.08a - 0.10b = 80

The two equations gotten above would be solved using simultaneous equation and the elimination method

a - b = 3000 equation 1

0.08a - 0.10b = 80 equation 2

Multiply equation 1 by 0.08

0.08 - 0.08b = 240 equation 3

Subtract equation 2 from 3

0.02b = 160

Divide both sides of the equation by 0.02

b = 8000

Substitute for b in equation 1

a - 8000 = 3000

Add 8000 to both sides

a = 11,000
