Bobby's dad is 41 and is 6 more than 5 times Bobby's age. Bobby's little sister Emma is one less than half his age. How old are
34kurt
Bobby is 7 and his sister is 3.

Explanation : his dads age : 41
since his dads age is six more than, you would subtract 6 from 41 to get 35.
and since 35 is 5 times bobby’s age you would divide 35 by 5 to get 7
So bobby is 7.

bobby’s sister :
bobby’s age : 7
bobby’s little sisters age is one less than half of his age you subtract 1 from 7 and you would get 6
Now that it’s one less you have to find half so divide 6 by 2 and you’ll get 3
So bobby’s sister is 3.



bobby’s age : 41 - 6 = 35
35 (divided by) 5 = 7
bobby’s sister : 7 - 1 = 6
6 (divided by) 2 = 3

25 points if you answer. Martin Rode his bike 3 2/3 miles in 16 1/2 minutes. Assume he wrote the same speed the entire time. Ho
Illusion [34]

Answer:

The speed is 2/9 miles per minute

Step-by-step explanation:

Speed is defined as the distance covered per unit time.

The formula for speed is given by:

Speed = \frac{distance}{time}

Let s be the speed, d be the distance and t be the time then

s = \frac{d}{t}

Given

d = 3\frac{2}{3} = \frac{11}{3}\ miles\\t = 16\frac{1}{2} = \frac{33}{2}\ minutes

The speed will be calculated by dividing the number of miles by minutes

So putting the values in the formula

s = \frac{\frac{11}{3}}{\frac{33}{2}}\\= \frac{11}{3} * \frac{2}{33}\\=\frac{1}{3} * \frac{2}{3}\\=\frac{2}{9}

Hence,

The speed is 2/9 miles per minute

Peggy had three times as many quarters as nickels. She had $1.60 in all. How many nickels and how many quarters did she have?. .
Andru [333]

Let

n-------> the number of nickels

q------> the number of quarters

we know that

1\ quarter=\$0.25\\1\ nickel=\$0.05

so

0.05n+0.25q=1.60 ----> equation A

q=3n ----> equation B

substitute equation B in equation A

0.05n+0.25[3n]=1.60

0.05n+0.75n=1.60

0.80n=1.60

n=2

Find the value of q

q=3*2=6

therefore

<u>The answer part a) is</u>

the number of nickels are  2  and the number of quarters are 6

<u>the answer Part b) is</u>

The expressions that represents the number of quarters is

q=3n
