So we need to represent the problem using an equation
900 = the original pile of bricks (x) + 25% more - 40% (original + 25% extra)
900 = x + .25x - .4(x + x*.25)
900 = x + .25x - .4x - .1x
900 = .75x
x = 1200
Answer:
C. 6°C
Step-by-step explanation:
-3°C + 9°C = 6°C
Answer: x=20
Step-by-step explanation:
the following angles are supplementary so they will add up to equal 180
4x+21 +2x +39=180
step 1 combine like terms
6x+60=180
step 2 subtract 60 from each side
6x=120
step 3 divide each side by 6
x=20
50/100*10
ANSWER: 5
So basically you have to divide 50 (the original price) with 100 and then multiply it with the increased percentage which is 10.Then you get your answer.
Answer:
2 periods
Step-by-step explanation:
Simple interest is compounded one time, usually annually, although it could be less time or longer. Thus I answer 2 periods. If your choices include 2 years, that is most likely the answer.
To find the answer,
$10,000 x .03 = $300.
$600 / $300 = 2 periods.
Hope this helps.
Good luck
