14 - x = 16
Subtract 14 from both sides
-x = 2
Divide by -1 (since -x is equivalent to -1*x)
x = -2
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
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:

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

Given

The speed will be calculated by dividing the number of miles by minutes
So putting the values in the formula

Hence,
The speed is 2/9 miles per minute
Answer:
7^2
Step-by-step explanation:
there is one law of exponent, where if you're dividing 2, and the base is the same, you can just subtract the exponents so-
Let
n-------> the number of nickels
q------> the number of quarters
we know that

so
----> equation A
----> equation B
substitute equation B in equation A
![0.05n+0.25[3n]=1.60](https://tex.z-dn.net/?f=0.05n%2B0.25%5B3n%5D%3D1.60)



Find the value of q

therefore
<u>The answer part a) is</u>
the number of nickels are
and the number of quarters are 
<u>the answer Part b) is</u>
The expressions that represents the number of quarters is
