Answer:
The Number is 8.
Step-by-step explanation:
Let the number be x.
Given:
1/2 is subtracted from four times the reciprocal of a number, the result is 0.
Hence the equation will become like;
Now Solving the equation we get.
Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.
Hence the number is 8.
Answer:
The total cost of the dried fruit.
Step-by-step explanation:
$2.50 is the cost of the dried fruit per pound.
2.5x means the total cost of the dried fruit ( x is the number of pounds of dried fruit and total cost = 2.5 times x in dollars).
Answer:
67
Step-by-step explanation:
Complementary angles add to 90 degrees
<A + <B = 90
x+10 + 3x+28 = 90
Combine like terms
4x+38 =90
Subtract 38 from each side
4x+38-38 = 90-38
4x = 52
Divide by 4
4x/4 = 52/4
x = 13
We want to find <B
<B = 3x+28
= 3(13) +28
= 39+28
=67
2 1/2 because if u take away 4 from 2 u get 2 and a half left
Answer:
2.5 km/h
Step-by-step explanation:
Here we have a distance problem where we are given the distance the time time:
Rate = ?
Time = 2hrs
Distance = 5km
The simplest way to do this is to rearrange the formula to suit our need and plug in the numbers:
Now, plug in the numbers and solve:
