100 dm is greater than 100 km.
You need to substitute the x and y values into the original and subtract 15 from each side to get b. You should get a b value of -20
Answer:
acute
Step-by-step explanation:
Evaluate the angle C = (11x + 85)/3 at x = 13:
C(13) = (143 + 85)/3, or 76 degrees. This is an acute angle (more than 0 and less than 90 degrees).
The proportion that could be used to solve for the variable is:
; p = 12 ⇒ b
Step-by-step explanation:
Direct proportion means that two (or more) quantities increase or decrease in the same ratio
- y = k x is the equation of direct proportion, where k is the constant of proportionality
is the another way to write a proportion
The number of pencils and the cost of them is increased together or decreased together
∴ The number of the pencils and their costs are in direct proportion
- By using the 2nd rule above
∵ The cost of the 7 pencils is $1.68
∵ The cost of p pencils is $2.88
∴ 
The proportion that could be used to solve for the variable is: 
∵ 
- By using cross multiplication
∴ p × 1.68 = 7 × 2.88
∴ 1.68 p = 20.16
- Divide both sides by 1.68
∴ p = 12
The value of variable p is 12
