If a+b=c and b+c+d and b+d=e
and if a=5
what is b,c,d,and e equal

Answers

Answer 1
Answer: so a+b=c
b+c=d?
b+d=e

a=5
subsitute
5+b=c
c=b+5
c-5=b

b=c-5 so
c-5+c=d
d=2c-5
b+d=e
c-5+2c-5=e






so
a=5
b=c-5
c=b+5
d=2c-5
e=3c-10

Answer:

Option A (89).

Step-by-step explanation:

Percentile is a statistic in which the an element at a certain percentage position is determined. To calculate the percentiles accurately, it is important that the data is present in the ascending order. Percentile is an important concept in data analysis. Interestingly, 50th percentile is the median of the data. The difference between the 75th and the 25th percentile is the interquartile range. To find the 85th percentile of the data, calculate 85% of 40, which is the number of elements in the data set. 40 * 85/100 = 34. The number on the 34th position is the 85th percentile of the data. It can be observed that 89 is on the 34th position. Therefore, Option A is the answer!!!

Answers

12) 8 liters in total. each glass holds 1/5 of a liter. 8 x 5 = 40 glasses.

13) 3bars/4people = 3/4 of a bar.

14) same concept as 13. .5quart/3people = (1/6) of a quart of milk.

15) 3 yards in total. divides it into pieces that are 1/4 yard long. so each 1 yard makes 4 pieces. that means 3 yards makes 12 pieces in total.
12) 5 glasses per liter. 5 * 8= 40 glasses

What is the sum of 3 1/10 and 1 3/4 . please help me with this .

Answers

the sum is 4 and 17/20.
first, you have to create a common denominator. the least common multiple of 4 and 10 is 20, so I used that.
since 10 is multiplied by 2 to achieve, twenty, we also multiply 1 by 2, which makes 3 and 2/10
4 on the other hand, is multiplied by 5 to achieve 20, so we multiply 3 by 5 also, which is 15.
from there, we have 3 2/20 + 1 15/20, which equals 4 17/20.
The sum or 3 1/10 and 1 3/4 is 5.

The residents of a city voted whether to raise property taxes. The ratio of yes votes was 7 to 4. if there were 5425 yes votes, what was the total numbers of votes?

Answers

Answer: 8525

Step-by-step explanation

Let the total number votes = x

Ratio of yes votes = 7

Ratio of no votes. = 4

Total vote. = 11

Total number that voted for yes

= 5425

Therefore total number of vote casted.

7/11 x X = 5425

7x/11 = 5425

7x = 5425 x 11

7x = 59675

To find x , divide through by 7

x = 59675/11

= 8525

Andre has 4 times as many model cars as Peter, and Peter has one-third as many model cars as Jade. Andre has 36 model cars. Write and solve an equation to find how many model cars Peter has. Using your answer from part a, write and solve an equation to find how many model car Jade has.

Answers

First solve what is probably 'part A.'
Peter has 36 ÷ 4; Peter has 9 model cars. Jade has 3 times as many as Peter; Peter has 1/3 as many as Jade, so 9 x 3 = 27, so Jade has 27 cars.

1st equation: 36 ÷ 4 = 9 -OR- 36 x 1/4 = 9
2nd equation: 9 x 3 = 27 -OR- (36 x 1/4) x 3 = 9
(36/4)3 = 9 would also work. I think the 1st equations would be best... just giving some choices...
