Multiply both numerator and denominator by 2.
4*2 = 8 & 5*2 = 10
4/5 is thus equal to 8/10 or eight-tenths.
With a bar duagram, just divide/split it up evenly into 5 parts then colour in 4 of the pieces. Then, divide as a whole now make it so there's 10 parts - do this by splitting each 5 parts into 2 (put line through middle) to make 10 parts. Now you will see that there is 8 parts that are coloured in for 10 pieces compared to 4 coloured parts when there was 5 pieces.
Answer:
the value of output is 29
Step-by-step explanation:
the output variable y is 12 less then the input variable x.
Input variable is x, output variable is y
output values = input variable - 12
now plug in the variable in the equation
output values = input variable - 12
Given the input value is 41
Substitute 41 for x
the value of output is 29
Answer:
Nina must drive 32.55 more miles.
To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is 5x.
Since 10 is being added to 5x, we subtract 10 from both sides of the equation to isolate the 5x.
On the left, the +10 and -10 cancel out and on the right, 20 - 10 is 10 and we have 5x = 10.
Now we can finish things off by just dividing both sides of the equation by 5. On the left the 5's cancel and on the right, 10 divided by 5 is 2 so <em>x = 2</em>.
Step-by-step explanation:
Well, if 1 gallon of gas = 1 hour then
2 hours would be 2 gallons so only 11 gallons of gas would be left in the tank and
13 hours would be 13 gallons, so 0 gallons of gas would be left in the tank
