Answer:
Step-by-step explanation:
k = 2h+9
h+16=k
h+16=2h+9
-h = -7
h = 7
hannah is 7 and kayla is 23
jacob is wrong because if u do 16*2+7 it’s 39 and 39-16 does not equal 16
<u>Correct</u><u> </u><u>question</u><u>:</u><u>-</u>

Answer:
y = 0.3
Step-by-step explanation:
Solve for y:
(3.2y - 1.8) - (5.2 y + 3.4) = -5.8
-(5.2y + 3.4) = -5.2y - 3.4:
3.2y - 1.8 -5.2y - 3.4 = -5.8
Grouping like terms, 3.2y - 1.8 - 5.2y - 3.4 = (3.2y - 5.2y) + (-1.8 - 3.4):
(3.2y - 5.2y) + (-1.8 - 3.4) = -5.8
3.2y - 5.2y = -2 y:
-2y + (-1.8 - 3.4) = -5.8
-1.8 - 3.4 = -5.2:
-5.2 - 2y = -5.8
Add 5.2` to both sides:
(5.2 - 5.2) - 2y = 5.2 - 5.8
5.2 - 5.2 = 0:
-2y = 5.2 - 5.8
5.2 - 5.8 = -0.6:
-2y = -0.6
Divide both sides of -2y = -0.6 by -2:




y = 0.3
-2
Because -2(10x+3) is (-20x-6) when you distribute
