In a fraction, the numerator is the number on the top.
Answer:
<h3>
Jake is 13 years old</h3>
Step-by-step explanation:
D - age of Dani
J = D+2 - age of Jake
E = 2J = 2(D+2) = 2D+4 - age od Ethan
Z = 2E = 2(2D+4) = 4D+8 - age of Zoe
The sum of their ages is 102:
D + J + E + Z = 102
D + D+2 + 2D+4 + 4D+8 = 102
8D + 14 = 102
-14 -14
8D = 88
÷8 ÷8
D = 11
J = 11+2 = 13
Answer:
g = 3.5
f = 78°
<u>Finding</u><u> </u><u>g</u><u>:</u>
25 is parallel to 8g - 3, so they are equal to each other.
25 = 8g - 3
28 = 8g
g = 3.5
<u>Finding</u><u> </u><u>f</u><u>:</u>
72° create a sum of 180° when adding to (f + 30) because they are supplementary.
72 + f + 30 = 180°
102 + f = 180°
f = 78°
Hope this helps!
