Answer:
125
Step-by-step explanation:
1.25=125/100=125%
Answer:
a unit means that we have one of something the unit rate means we have a rate for one or something we write the rate as a ratio with a denominator of 1
so false
Answer:
b+1/3
Step-by-step explanation:
You don't know what "b" is so its just b +1/3
Suppose the time taken for the repairman to fix one pair of shoes is x, time taken by the assistant will be 1.5x.
The number of shoes repaired by shoe man in an hour will be:
1/x
the number of shoes prepared by assistant in 1 hour will be:
1/1.5x
the number of shoes repaired by both of them in 1 hour will be:
8/20
hence;
1/1.5x+1/x=8/20
2.5/(1.5x)=2/5
cross-multiplying our equation we get:
2.5*5=1.5x*2
7.5=3x
x=7.5/3
x=2.5 hours
therefore we conclude that it takes the repairman 2.5 hours to fix one pair of shoes.
Answer:
<h2>- 2</h2>
Step-by-step explanation:
The slope intercept form of an equation of a line:
m - slope
b - y-intercept
We have the equation of a line in the standard form
Convert to the slope-intercept form:
<em>subtract 4x from both sides</em>
<em>divide both sides by 2</em>
Therefore the slope is equal to -2.
Other method:
If we have the equation of a line in standard form Ax + By = C
or in general form Ax + By + C = 0, then the formula of a slope is
We have A = 4 and B = 2. Substitute:
