Answer:
20+16= 36
Step-by-step explanation:
Answer:
There are 40 problems on the test
Step-by-step explanation:
Let p = the number of problems on the test
The number of problems on the test times the percent correct is the number correct
p * 85% = 34
p * .85 = 34
Divide each side by .85
p * .85/.85 = 34/.85
p = 40
There are 40 problems on the test
If you would like to solve the equation b^2 + 9 * b + 18 = 0 for the variable b, you can do this using the following step:
b^2 + 9 * b + 18 = 0
(b + 3) * (b + 6) = 0
Result:
1. solution: b = - 3
2. solution: b = - 6
Answer:
y ∝ m and 1760 is a constant of proportionality.
Step-by-step explanation:
The relation between a distance in the yards (y) and the same distance in miles (m) is described by the equation y = 1760m.
So, the graph of the above equation passes through the origin(0,0) and it will be a straight line with a constant slope of 1760.
Therefore, a measurement in yards and a measurement in miles are in the relation of proportionality for the same distance.
Hence, y ∝ m and 1760 is a constant of proportionality. (Answer)
