Answer:
3x - 10 = -21
add 10 on both side
3x-10+10=-21+10
3x=-11
divide both side by 3
3x/3=-11/3
x=-11/3
Step-by-step explanation:
2. -22 - 4x = 12
add 22 on both side
-22+22-4x=12+22
-4x=36
divide both side by -4
-4x/-4=36/-4
c=-9 is your answer
Answer:
AE=22.4
Step-by-step explanation:
BE is 1/2 of BC
BC is 20 cm All sides of a square are equal
BE = 1/2 BC Property of a midpoint.
BE = 10
Now just use Pythagorus
AB^2 + BE^2 = AE^2
AE^2 = 20^2 + 10^2 Perform the sqrs
AE^2 = 400 + 100 Add the terms
AE^2 = 500 Take the square root of both sides
√AE^2 = √500
AE = 22.36
AE ≈ 22.4
Hello
1 km = 1000 m
12 km = 12,000 m
