Answer:
210
Step-by-step explanation:
Least common multiple can be found by multiplying the highest exponent prime factors of 30 and 42
GCF(30,42) = 6
LCM(30,42) = ( 30 × 42) / 6
LCM(30,42) = 1260 / 6
LCM(30,42) = 210
hope this helps :)
Since BE is 90 degrres
X +40 need to also equal 90
so x = 90-40 = 50 degrees
Answer:
8 units
Step-by-step explanation:
b(14)/2 = 56
14b = 112
b = 8 units
Answer:
x = 4
y = 1
Step-by-step explanation:
x = 3y + 1 (Multiply everything by -2)
2x + 4y = 12 (Transfer 4y to the right of the = sign)
2x = -4y + 12
-2x = -6y - 2
0 = -10y + 10
-10 = -10y
y = 1
x = 3y + 1
x = 3(1) + 1
x = 3 + 1
x = 4
