Mathematics
1 answer:
belka [17]3 years ago
7 0

Answer:

D

Step-by-step explanation:

First we need to figure out how many people are going on the field trip

if each class has 27 people going and there are 6 classes, 6*27=162

162 ppl are going. If 3 buses can hold 48 ppl then 3*48=144

3 buses are not enough, if we were to bring in one more bus 4*48=192

there would be enough place for everyone

Solve a=2b-c for b<br><br> Can someone help me
Sauron [17]

Answer:

b=\frac{a}{2} +\frac{c}{2}

Explanation:

While solving literal equations could be quite overwelhming, simply solve it by using normal equation solving methods.

For example, if you were to solve 2x + 3 = 9

You would add 3 on both sides and divide both sides by 2 to determine x.

Do the same thing for literal equations, and if in doubts, plug in numbers to check your work.

Step-by-step explanation:

For this problem, add c on both sides, we do this because we are aiming to eliminate the c from both sides.

a+c =2b

In order to find the value of b, divide both sides by 2, we do this because we want to get rid of the coefficient.

This should leave you with the answer of b=a/2 + c/2

What is the best estimate of the sum of the fraction? 31/4 +17/3 +8/18
Bogdan [553]

The best estimate of the sum of the expression given is \rm 13 \dfrac {31}{26}

What is a Fraction ?

A fraction is written as p/q , where q \rm \ne 0

It is asked to determine the sum of the fraction

31/4 + 17/3 + 8/18

Taking the LCM of 4 , 3 , 18

LCM of 4 , 3 ,18 is 36

Therefore

\rm \dfrac{ 31 *9 + 17 *12 + 8 *2}{36 }

(279+204+16) /36

499 / 36

\rm 13 \dfrac {31}{26}

Therefore the best estimate of the sum of the expression given is \rm 13 \dfrac {31}{26}.
