Answer/Step-by-step explanation:
17. Slope = rise/run
rise = 5
run = 7
Slope = -⁵/7
18. Slope = rise/run
rise = 4
run = 4
Slope = -⁴/4 = -1
19. Slope = rise/run
rise = 3
run = 5
Slope = -⅗
20. Slope = rise/run
rise = 4
run = 1
Slope = -⁴/1 = -4
Answer:
$21
Step-by-step explanation:
70%=0.7
30*0.7=21
Answer:
1
Step-by-step explanation:
These numbers have no common factors. The only comon factor they have is one. Therefore, the GCF of 117, 19, and 110 is one.
22.5 (shower) = X (variable used in place of the amount of water she uses to wash clothes) - 7.5 (the amount she used in the shower is 7.5 gallons less than she uses for washing clothes)
22.5 = X - 7.5 《 This is the equation.
Solve is by adding 7.5 to both sides to cancel out the negative 7.5 and you get (X = 30).
The pattern is dividing by 2.
512, 256, 128, 64
512/2 = 256, 256/2 = 128, 128/2 = 64
64/2 = 32, 32/2 = 16, 16/2 = 8, 8/2 = 4, 4/2 = 2, ...
