P of triangle = a + b = c = 90

<span>ratio 3:4:5
so a = 3x, b = 4x , c = 5x

3x + 4x + 5x = 90
12x = 90
x = 90/12 = 7.5

a = 3x = 3 * 7.5 = 22.5
b = 4x = 4 * 7.5 = 30
c = 5x = 5 * 7.5 = 37.5

Answer:
1st side = 22.5
2nd side = 30
3rd side = 37.5

Double check: 22.5 + 30 + 37.5 = 90 (perimeter)</span>

To make the sum or difference of 3/4+1/3
rusak2 [61]

Answer:

13/12 or 1 1/12

Step-by-step explanation:

First, I like to line up the fractions like this:

3/4

1/3

You can't add them yet because they have different denominators, so we have to get them to the same denominator first. What is a number 3 and 4 can be multiplied by? Let's use 12. So, we want both of their denominators to be 12. How do we do that? 4 times what equals 12? 3. However, whatever you multiply the denominator by, you have to do to the numerator as well. Here is what we have:

3/4 x 3

1/3

3x3 equals 9, so your first fraction is 9/12. Then, do the second fraction. 3 times what equals 12? 4. So, multiply the numerator, 1, by 4 to get 4. So, your second fraction is 4/12. Now, you have to add them together, 9+4 = 13. The denominator stays the same. So, your sum is 13/12. If you want to, you can also simplify it to a mixed number into 1 1/12.

Q19. Look at the image.
Neko [114]

Answer:

It's C

Step-by-step explanation:

Because if you look at the other numbers they all add up to the next number by 4. 4+4=<em>8  </em>8+4=<em>12  </em>12+4=<em>16</em>  16+4=<em>20</em>  20+4=<em>24 </em>

<em>Therefore, x intercept </em>is 24 and <em>y</em> intercept is 18. Hope this is correct if it's not  correct then I'm very sorry. Have a nice day. ;)
