5x + 12 + 3x = 6(x + 4)
5x+3x+12=6(x+4)
Multiply the bracket by 6
(6)(x)(6)(+4)=6x+24
5x+3x+12=6x+24
8x+12=6x+24
Move 6x to the other side. Sign changes from +6x to -6x.
8x-6x+12=6x-6x+24
8x-6x+12=24
2x+12=24
Move 12 to the other side. Sign changes from +12 to -12.
2x+12-12=24-12
2x=12
Divide by 2 for both sides.
2x/2=12/2
x=6
Answer: x=6

Step-by-step explanation:
Answer:
96°
Step-by-step explanation:
The measure of arc EC is twice the measure of ∠DEC, so is ...
arc EC = 2×68° = 136°
The measure of arc BC is found from the sum of arcs around a circle.
BC +CE +EB = 360° = BC +136° +128°
BC = 96° . . . . . subtract 264°
Answer:
The lcm (least common multiple) of 4 and 12 is 12.
Step-by-step explanation:
Find the prime factorization of 4
4 = 2 × 2
Find the prime factorization of 12
12 = 2 × 2 × 3
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:
LCM = 2 × 2 × 3
LCM = 12
