The far left column represents the 10's place and the digits to the right represent the 1's place.

look at the "3" row. How many digits are greater than 2? → 4,4,4,5,7 = 5 digits

How many digits are in the "4" row (representing ages in their 40's)? → 6 digits

How many digits are in the "5" row (representing ages in their 50's)? → 5 digits

How many digits are in the "6" row (representing ages in their 60's)? → 4 digits

How many digits are in the "7" row (representing ages in their 70's)? → 1 digit

How many customers are older than 32? 5 + 6 + 5 + 4 + 1 = 21

I’m not sure where to begin

(a)

we are given

the price of apple suddenly up by $0.75

Let's assume original price be 'p'

we are given

Sam bought 3 pounds of apple at the new price total is $5.88

so, new price = old price +0.75

price of 3 apples $=3(p+0.75)$

we are given that price is 5.88

so, we get equation as

$5.88=3(p+0.75)$ .......Answer

(b)

Since, original price is p

so, we have to solve for p

$5.88=3p+2.25$

$5.88-2.25=3p+2.25-2.25$

$3.63=3p$

$p=1.21$

so, original price is $1.21 per pound........Answer

Simplify the following :

dlinn [17]

Answer:

1. 95/96

2. 27/7

3. -8/245

Explanation:

1. First add together the two fractions 3/4 + 5/6. Find the least common denominator. In this case we can use 12. The 3/4 changes to 9/12 and the 5/6 changes to 10/12. adding these together we get 19/12. Next we divide 8/5 by 19/12. We use the keep, change, flip method to change the divide to multiply. keep the first fraction, change divide into multiply, and then take the reciprocal of the second fraction. You will now do 5/8 x 19/12. We now get 95/96 (I made a mistake in the answers the first time because I was rushing)

2. Divide the 3/2 and the 8/9 first. I will use the KCF (keep, change, flip) method to divide. 3/2 x 9/8 = 27/16 Now we divide the 7/16. After using KCF we can simplify and cross cancel (simplfy after changing the fraction and signs) 27/16 x 16/7 --> 27/1 x 1/7 The answer will come out to be 27/7

3. since there are no parentheses divide first. Use KCF and after you get the answer multiply (it is the same using negative numbers just watch out for signs)

Step-by-step explanation:

You can find two kind of expressions in this property:

- Distributive property of multiplication over addition: When you mulitply a sum by a number. For example:
