Answers

7a - 4b

Step-by-step explanation:

Add the numbers ending with 'a' together, and then add the numbers ending with 'b' together.

First of all, I will put the letters beside each other.

2a + 5a + 3b - 7b

2a + 5a = 7a

3b - 7b = - 4b

Therefore, the answer is 7a - 4b.

Joy has a ribbon that measures 16 yards. She cuts 9 pieces of ribbon to decorate gifts. Each piece of ribbon that Joy cuts measures 4 feet.

What is the length, in yards, of the remaining ribbon?

Answers

Answer:

4 yds

Step-by-step explanation:

So... 16 yards is 48 feet (because one yard is 3 feet so I just multiplied by 3)

and she cuts 9 pcs of ribbon each 4 feet

so it's 9 x 4 = 36

48 - 36 = 12

And 12 feet equals 4 yards

So, Joy has 4 yards of remaining ribbon

Answer:

9.3 yards

Step-by-step explanation: the exact answer is 9.3333333

A charity distributed 80 000 emergency packages during 2018. This number is
expected to increase by 15% each year.
Calculate how many emergency packages the charity expects to distribute in 2021.

Answers

Answer:

121670

Step-by-step explanation:

The number of packages can be defined with the function:

P(t) = P(t-1)*1.15 where t = the years and 1.15 represents the 15% increase.

Packages during 2018: P(2018) = 80000

Packages during 2019: P(2019) = P(2018)*1.15 = 92000

Packages during 2020: P(2020) = P(2019)*1.15 = 105800

Packages during 2021: P(2021) = P(2020)*1.15 = 121670
