suppose a and b give the population of two states where a > b. compare expressions and tell which of the given pair is greater or if the expressions are equal. 1. b/a+b and 0.52. a+13c and b+13c is the population of a third state3. a-b/2 and a-b/24. a+b and 2b5. 5(a+b) and (a+b)5

Answers

Answer 1

Answer:

Answer:

We are given that a>b.

1) $(b)/(a+b)$ and 0.5

we know that a>b

⇒ a+b>b+b

⇒a+b>2b

⇒ $(b)/(a+b)<(1)/(2)=0.5$

2) a+13c and b+13c is the population of a third state.

so, a+13c>b+13c

3) both the given expressions are same i.e.

$(a-b)/(2)$

4) a+b and 2b

we know that a>b

⇒ a+b>b+b

⇒a+b>2b.

5) both the given expressions are same i.e. 5(a+b) or (a+b)5 since we have to multiply (a+b) and 5.

Jude has seven times as many dimes as nickels their value is $5.25 how many nickels does he have.49
15
7

Answers

Let dimes be represented by d and n for nickels;
1 dime= 0.1 dollars
1 nickel=0.05 dollars
0.1d+0.05n=5.25
d=7n
so,
0.1(7n)+0.05n=5.25
0.7n+0.05n=5.25
0.75n=5.25
n=7
There are 7 nickels and 49 dimes

1 nickel = $0.05
1 dime = $0.10

n - number of nickels
7n - number of dimes

A equation:

0.05n + 0.1 · 7n = 5.25
0.05n + 0.7n = 5.25
0.75n = 5.25 |divide both sides by 0.75
n = 7

Answer: He have 7 nickels.

You are visiting baltimore, MD and a taxi company charges a flat fee of 3.00 for using the taxi and 0.75 per mile. How much woks a taxi ride for 8 miles cost

Answers

Answer: the cost of riding the taxi for 8 miles is $9

Step-by-step explanation:

The taxi company charges a flat fee of 3.00 for using the taxi and 0.75 per mile. This means that the total cost of using the taxi and travelling x miles would be

3 + 0.75x

This is the equation representing the situation.

To find the cost of riding the taxi for 8 miles, we would substitute x = 8 in our equation. It becomes

Therefore, the total cost of riding the taxi for 8 miles would be

3 + 0.75 × 8

= 3 + 6 = $9
