Let Joy be x years old
<span>Joy's brother's age is 3 years older than twice joy's age.
</span>Joy's Brother = 2x + 3
<span>The sum of Joy's age and her brother's age is 24.
x + 2x + 3 = 24
3x + 3 = 24
3x = 24 - 3
3x = 21
x = 21 </span>÷ 3
x = 7
Joy:
x = 7
Brother:
2x + 3 = 2(7) + 3 = 17
Difference in their age = 17 - 7 = 10 years
They are 10 years apart.
Answer:
angle i, which is D)
Notice that X and I are both in the middle of the triangles.
Answer:
Step-by-step explanation:
additive property of length
Corresponding Part of Congruent Triangle
L+L+(L-4)+(L-4)=72
4L-8=72
4L=80
L= 20
so W= 20-4 or 16
