Answer:
Step-by-step explanation:
5x+4<x-5
5x-x<-5-4
4x<-9
x<-9/4
x=(-∞,...,-4,-3]
Answer:2 years
Step-by-step explanation:
7+10+x=27
7 is how long her hair is and it grows 10cm every year, so
27-10=17
17-10=7
You subtracted 10 twice so it's 2 years:)
Answer:
Step-by-step explanation:
If AB and DE are equidistant from the center, that means that they are the same length. We set the equations equal to one another and solve for x:
3x - 7 = 5(x - 5) and
3x - 7 = 5x - 25 and
18 = 2x so
x = 9. Now we sub that into the expression for AB (or DE since they're the same length):
3(9) - 7 = 20
Both AB and DE measure 20 units.
Answer:
The total change in square yards will be 9 sq. yards.
Step-by-step explanation:
Nien has a flower farm. He cuts 4 square yards of flowers one day and 5 square yards of flowers the next.
We have to use the addition operation to find the total change in the square yards.
Therefore, the total change in square yards will be (4 + 5) = 9 sq. yards. (Answer)
