Part 2....lol....I cant draw a model.
5/6 + 1/4.
steps involved : find a common denominator. Make both fractions have that denominator by converting them. Add fractions. Turn to mixed numbers if necessary.
5/6 + 1/4....common denominator 12
10/12 + 3/12 =
13/12 or 1 1/12
I dont know what to put foe reasoning other then that you can't add/subtract fractions unless they have the same denominator.
================
3/4 - 2/3
steps involved: find the common denominator to both fractions. Convert both fractions so they have the same denominator. Subtract them.
3/4 - 2/3....common denominator is 12
9/12 - 8/12 =
1/12
====================
2/3 * 3/8......multiply straight across.....numerator with numerator, denominator with denominator. Reduce when needed.
2/3 * 3/8 = (2 * 3) / (3 * 8) = 6/26 reduces to 1/4
with multiplication / division of fractions, common denominators are not necessary
===================
(3/8) / (3/4) =
3/8 * 4/3 =
12/24 reduces to 1/2
when dividing with fractions, u flip what u r dividing by, then multiply
Answer: 36
Step-by-step explanation:
Answer: It want let me put the answer in
Step-by-step explanation:
Answer:
Expand the left side, group like terms on both sides, and get
(2a)x + 3a = 10x + 15
To be true for all x, equate like terms from both sides and get
2a = 10
3a = 15
Solution: a = 5
You can test the answer.

You can test the answer.
b + p = 14 and 0.80 b + 2 p = 20.80 are the system of equations.
Step-by-step explanation:
Step 1 :
Let b be the number of bananas
Let p be the number of peaches
Given that the total of bananas and peaches that Emily bought = 14
Hence we have,
b + p = 14
Step 2 :
Cost of one banana = $0.80
Cost of one peach = $2
Cost of all the bananas and peaches Emily bought = $20.80
So sum of b bananas costing $0.80 and sum of p peaches costing $2 each is $20.80
Hence we have
0.80 b +2 p = 20.80
Solving for the above 2 equations we can get the value for b and p which will give the number of bananas and peaches bought
Step 3 :
Answer :
The system of equations that could be used to find the number of the bananas and the number of the peaches that Emily bought is given by
b + p = 14
0.80 b +2 p = 20.80
