16x+3y=251 and 8x+4y=148 then you set them up to each other and cancel one coefficient through elimination or find out what X or Y equals and substitute into either equation
X= 14
2(X+4) = 2x+8
3x-6 = 2x+8
-6=2x-3x+8
-14 = -1x
X=14
Answer:
13.27 cm
Step-by-step explanation:
The hypotenuse is always the longest side so:
a^2 + 20^2 = 24^2
a^2 + 400 = 576
a^2 = 176
a = 13.27
Answer: Sup. it's 16
Step-by-step explanation: Hope dis helps
if x = 2 and our equation is 10 +3(12 ÷ 3x), then u use substitution
So, the equation would become 10 + 3(12 ÷ 3(2)), which is 10 + 3(12 ÷ 6)
12÷6= 2, so the equation becomes 10 + 3(2).
3(2) = 6, so the equation would be 10 + 6 = 16
if you don't have a Unit Circle, this is a good time to get one, you'd need it, you can find many online.
