I believe the answer is d
X + (2 + x) + (4 + x) = 60
3x + 6 = 60
3x = 54
x = 18
x + 2 = 20
x + 4 = 22
Their ages are 18, 20, 22
Answer:
The correct answer is A.
Step-by-step explanation:
We are given:
The measure of two complementary angles are in the ratio 1 : 5
We know that the sum of complementary angles is 90 degree
Let the first angle be x
Let the other angle be 5x
Thus the equation we get:
x+5x = 90 degree
6x=90 degree
Divide both sides by 6
6x/6= 90/6
x= 15 degree
Now put the value of x in 5x
5x = 5(15)
= 75 degree
Thus the correct option is 15 degree, 75 degree....

c = 13
Step-by-step explanation:
substitute c for 26 and do 26 divided by 2, which will then give u the answer
Answer: ![\bold{(2)\ \dfrac{5}{2}}](https://tex.z-dn.net/?f=%5Cbold%7B%282%29%5C%20%5Cdfrac%7B5%7D%7B2%7D%7D)
<u>Step-by-step explanation:</u>
In order for the equations to have no points of intersection, they must be parallel lines. This means they have the same slope but different y-intercepts.
So, need an equation that has the same slope as (3, -7) and (9, 8). Use the slope formula: ![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![m=\dfrac{8-(-7)}{9-3}=\dfrac{15}{6}=\dfrac{5}{2}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B8-%28-7%29%7D%7B9-3%7D%3D%5Cdfrac%7B15%7D%7B6%7D%3D%5Cdfrac%7B5%7D%7B2%7D)
