Answer:
The missing addend is 1/20
Step-by-step explanation:
Variable x: missing addend
4/10 + x = 45/100
When adding or subtracting fractions, the denominators must be the same number.
To convert 10 to 100, we must multiply 10 by 10.
If we multiply 10 to the denominator, we must do the same to the numerator (multiply by 10).
4 × 10 / 10 × 10
40/100
Use this fraction in the equation now
40/100 + x = 45/100
Now isolate the variable, x, by subtracting 40/100 from both sides
40/100 - 40/100 + x = 45/100 - 40/100
When subtracting fractions, only subtract the numerators. The denominators remain the same
x = 5/100
Simplify 5/100
Both numbers can be divided by 5
5 ÷ 5 / 100 ÷ 5
1/20
The answer is B and I am certain
Because 2x5 is 10 and 2xr is 2r
So it’s 10+2r
Answer:
1.8 hours ( 108 minutes)
Step-by-step explanation:
10% of 2 hours is 12 minutes
120 minutes - 12 minutes = 108 minutes
First, you would subtract 4.25 from 6.25 and that would be equal to 2.
Then, you would take 2.25z and subtract it from 3.5z and it would equal 1.25z.
Next, you would separate the z by dividing 1.25 on both sides. Z=1.6
Answer: B
There is only one solution.
