Answer:
Step-by-step explanation:
16in
Mr. Abbot mowed 1/4 of his lawn.
His son mowed 3/7 of the lawn.
The first thing to do is get a common denominator, in this case a good one to use is 28. it has to be a number divisible by 4 and 7.
1/4=7/28
3/7=12/28
so now we can see that the son mowed more. now add these two numbers together to get how much they mowed in total
(7+12)/28=19/28 of the lawn is mowed.
that means 9/28 of the lawn still has to be mowed.
Answer:
y = 3 + 2x
Step-by-step explanation:
Let y = Total number of food items
Let x = Number of guests
y = 3 + 2x
Example:
If there are 14 guests, we have:
y = 3 + 2(14)
y = 3 + 28
y = 31
So the equation gives us a total number of 31 food items from both you and the guests.
Answer:
z =2.76
