1.8 -0.4y = 2(1.1 - Y)

y=0.25

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1.8−0.4y=2(1.1−y)

1.8+−0.4y=(2)(1.1)+(2)(−y)(Distribute)

1.8+−0.4y=2.2+−2y

−0.4y+1.8=−2y+2.2

Step 2: Add 2y to both sides.

−0.4y+1.8+2y=−2y+2.2+2y

1.6y+1.8=2.2

Step 3: Subtract 1.8 from both sides.

1.6y+1.8−1.8=2.2−1.8

1.6y=0.4

Step 4: Divide both sides by 1.6.

1.6y/1.6 = 0.4/1.6

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
