24 yrs, might not be the answer

3%=0.03 you have to get to 6%=0.06

So you find the value of each month in 3%

So 3% divided by 12 months = 0.0025

Now you have the value of each month MULTIPLY until you get 0.06
So: 0.0025 x 1, 2, 3, 4,…….. and so forth

So the your result will be

0.0025per months x 24yrs = 0.06 = 6%

How do you solve 1/3+1/4?
Otrada [13]

Answer:

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(1/3×4/4)+(1/4×3/3)=?

Complete the multiplication and the equation becomes

4/12+3/12=?

The two fractions now have like denominators so you can add the numerators.

Then:

4+3

12= 7/12

This fraction cannot be reduced.

Therefore:

1/3+1/4=7/12

DH = x + 2, HF = 2y, GH = 3x – 3, and HE = 5y + 1. Find the values of x and y.
nikitadnepr [17]
<span>DH = x + 2, HF = 2y, GH = 3x – 3, and HE = 5y + 1

DH = HF
</span>x + 2 = 2y
and
GH = HE
3x – 3 = 5y + 1

so now you have
x + 2 = 2y
3x – 3 = 5y + 1

re-write and simply
x = 2y - 2
3x = 5y + 4

substitute x = 2y - 2 into 3x = 5y + 4
3x = 5y + 4
3(2y - 2) = 5y + 4
6y - 6 = 5y + 4
y = 10

x = 2y - 2
x = 2(10) - 2
x = 20 - 2
x = 18

answer
x = 18 and y = 10

Vaselesa [24]

Answer:

Step-by-step explanation:

1). 3x + 10

3(2) + 10

= 16

2). 14 - 2y

14 - 2(-3)

= 20

3). 7x - 5y

7(2) - 5(-3)

= 29

4). 5x + 7

5(2) + 7

= 17

5). 2x + 3y

2(2) + 3(-3)

= -5

6). 6y - 5x

6(-3) - 5(2)

= -28
