Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard. Zach will get $25 to clean a garage and Y dol
lbvjy [14]

Answer:

Expression for Larry will be;

\$21 + \$Y\geq \$X

Expression for Zach will be;

\$25 + \$Y\geq \$X

Step-by-step explanation:

Given:

Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard.

Amount for each flower bed he weeds = $7

Number of flower bed he weeds = 3

Total amount he gets for 3 flower bed he weeds = \$7\times 3 =\$21

Amount earn to edge a yard = Y

Total amount Larry will earn = $21 + $Y

Now Zach will get $25 to clean a garage and Y dollars to wash a car.

Amount earned to clean garage = $25

Amount earned to wash as car = $Y

Total Amount Zach will earn = $25 + $Y

The Both have to make X dollars to meet their goals.

Expression for Larry will be;

\$21 + \$Y\geq \$X

Expression for Zach will be;

\$25 + \$Y\geq \$X

How to solve -13=5(1 4m)-2m?
Paladinen [302]
First, you would multiply: -13 = 70m - 2m. Then, you subtract the like terms, which would be 70m - 2m: -13 = 68m. You are looking for what m is, so you would divide 68 on both sides: m = - 13 / 68. In math, people would usually like fractions more than decimals, but if you are looking for the decimal number, it would be m ≈ - 0.19.

Tahmid has 96 G.I. Joe action figures and Sandeep has one-third as much as Tahmid does. How many figures must Tahmid give Sandee
Ann [662]
Tahmid has 96 figures, Sandeep has 1/3 of it so 
96(1/3) = 96/3 = 32
Sandeep has 32 figures

Tahmid 96 ; Sandeep 32

How many must tahmid give so they have the same figures?
First take the difference of the two so we know how many tahmid can give. 
96-32 = 64
now they each have 32 and 64 give or keep. for each one tahmid gives, he must keep one himself so to match the number they both own. so we divide the number of 2, one part to give, the other part to keep himself.
64/2 = 32
So, Tahmid must give Sandeep 32 figures to have equal number of figures of 64 each.
