butalik [34]

Answer:

mary=10 jack=15

Step-by-step explanation:

After 4 years Mary (x+4), Jack's age (x+5) + 4.

sum of the ages after 4 years :(x+4) + (x+5) +4=33 

Simplifying the equation:

2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age

10 + 5 = 15 which is Jack's age.

Melanies superhero costume for the school play requires 1 5/6 yards of green fabric and 1/3 yard of yellow fabric.How many total
Katen [24]

Answer:

2\frac{1}{6} yards of fabric.

Step-by-step explanation:

It is required 1\frac{5}{6} yards of green fabric and \frac{1}{3} yards of yellow fabric to make the costume for the school play.

We are asked to calculate the total yards of fabric required.

So, the total yards of fabric needed will be the sum of green fabric length and yellow fabric length.

So, the total yards of fabric are needed for costume will be (1\frac{5}{6} + \frac{1}{3}) = (\frac{11}{6} + \frac{1}{3}) = \frac{13}{6} = 2\frac{1}{6} yards. (Answer)
