Solution:

The expression "a(b-c)" is an example of distributive property. To simplify it, simply multiply a by the terms inside the bracket.

<u>Simplifying the distributive property.</u>

  • => a(b - c)
  • => (a x b) + (a x -c)
  • => ab - ac

Hence, the simplified expression is ab - ac.

We can use the distributive law to simplify it or factor it but more

\\ \tt\hookrightarrow a(b-c)

\\ \tt\hookrightarrow a(b)-a(c)

\\ \tt\hookrightarrow ab-ac

WHUR Radio uses 1/5 of its of its 10 hours of daytime broadcast for commercial and 1/2 for music. How much is left for news?
Nataly [62]

Answer: 3 hours

Step-by-step explanation:

From the question, we are informed that WHUR Radio uses 1/5 of its of its 10 hours of daytime broadcast for commercial and 1/2 for music.

Hours used for commercial:

= 1/5 × 10

= 2 hours

Hours used for music:

= 1/2 × 10

= 5 hours

Hours left for news will be:

= 10 hours - 2 hours - 5 hours

= 3 hours

What interest is needed to earn $137.50 on a deposit of $500 for five years if it earns simple interest?
sineoko [7]

Answer:

5.5%

Step-by-step explanation:

Given data

Simple interest =  $137.50

Principal= $500

time = 5 years

We want to find the rate  R

Simple interest= PRT/100

137.50 = 500*R*5/100

137.50=2500R/100

cross multiply

137.5*100= 2500R

13750= 2500R

divide both sides by 2500

R= 13750/2500

R=5.5%

Hence the rate is 5.5%
