Mathematics
1 answer:

Answer: LCD = 40

Equivalent Fractions with the LCD

2/5 = 16/40

1/8 = 5/40

Step-by-step explanation: If necessary, rewrite input as fractions: 2 / 5, 1 / 8 The least common multiple (LCM) is 40. The lowest common denominator (LCD) is therefore 40. Rewriting the original inputs as fractions equivalent to the LCD: 16 / 40, 5 / 40

Hope I helped!!!! :):):)

serg [7]

Step-by-step explanation:

5x+52=9x+20

subtract 5x on both sides

subtract 20 on both sides

32=4x

divide by 4 on both sides

x=8

plug in x to the equations for A, D, and C

A and D are 92°

C is 56°

B and C will add up to 90, so

90-56=34°

13y-6=34

add 6 on both sides

13y=40

divide by 13

y=40/13 (I don't wanna calculate that)

Answer:

f(x) = 6x + 5

g(x) = 2x - 7

Step 2: Find f(g(x))

f(g(x)) = 6(2x - 7) + 5

f(g(x)) = 12x - 42 + 5

f(g(x)) = 12x - 37
