Answer:
y = -14, x = -17
Step-by-step explanation:
-2(y-3)+3y=-8
-2y+6+3y=-8
y+6=-8
-6. -6
y=-14
x = y-3
x = -14-3
x = -17
Answer:
The total answer is $14.16 because the tip would be $2.16 so add it with 12 and you get $14.16.
A. 2(x+14) = 42
(2x = 14
x = 7
2(7) + 2(14) = 14 + 28 = 42)
Answer:
5cm
Step-by-step explanation:
To find the missing side we use the hypotenuse theorem.
a^2 + b^2 = c^2
The longest side of the triangle would be c. So substitute the numbers into the variables.
a^2 + 12^2 = 13^2
a^2 = 13^2 - 12^2
a^2 = 169 - 144
a^2= 25
a = √25
a=5
The missing leg's length is 5cm
Add up the numbers of the sides you have then subtract it from the Magic total
