For this answer it is:
12 inches = 36 feet
Its pretty simple
9x-7y = 22
x + 3y = -24
(9x-7y = 22)
-9(x + 3y = -24)
= -9x -27y = 216
+ 9x-7y = 22
= -34y = 238
= / -34 = 238/-34
y = -7
now plug -7 in one of the equation
x + 3(-7) = -24
x -21 = -24
+21. +21
x = -3
so answer is x = -3 and y = -7
Answer:
If it took the motorcycle 2 hours to cover 20km, then the average speed is 10km per hour.
Speed is equal to distance over time. So 20km divided by 2 hours is 10 km per hour.
Answer:
Hello! answer: 39
Step-by-step explanation:
Formula for triangles area: base × height ÷ 2
Formula for squares area: base × height
5 × 3 = 15 15 ÷ 2 = 7.5 since there are 4 triangles that are the exact same I will just multiply by 4 so I have all the triangles so 7.5 × 4 = 30 now the square is just 3 × 3 so... 3× 3 = 9 now we add these up 30 + 9 = 39 therefore the surface area is 39
