Answer:
Step-by-step explanation:
12.5z - 6.4 =-8z + 3(1.5z - 0.5)
12.5z - 6.4 = - 8z + 4.5z - 1.5
12.5z - 6.4 = - 3.5z - 1.5
Bringing like terms on one side
12.5z + 3.5z = - 1.5 + 6.4
16z = 4.9
z = 4.9/16
Answer:
Step-by-step explanation:
In order to make a specific shade of green paint, a painter mixes 1 1/2 quarts of blue paint. Converting 1.5 quarts to cup,
1 quart = 4 cups
1.5 quarts = 1.5 × 4 = 6 cups
She also used 1/2 gallon of white paint. Converting 0.5 gallons to cup,
0.0625 gallons = 1 cup
0.5 gallons = 0.5/0.0625 = 8 cups
This means that the ratio of cups of blue paint to green paint to white paint is 6: 2 :8
Total ratio = 6 +2 + 8 = 16
To make 100 cups of this shade of green,
Cups of blue paint needed = 6/16 × 100 = 37.5 cups
Cups of green paint needed = 2/16 × 100 = 12.5 cups
Cups of white paint needed = 8/16 × 100 = 50 cups
Answer:
x-1
Step-by-step explanation:
it is x-1 because 1 is subtracted from a number and the number is x. when it says subtracted from you flip the equation and put the first number last and put a minus sign.
