The sum of 2 numbers is 76. 1/3 of the first number plus 1/2 of the second number is 34. What are the two numbers? What is the d
ifference between the second number and first number?
2 answers:
Ok so we have 2 equations here...
x + y = 76
1/3x + 1/2y = 34
First solve for x in the 1st equation...
x + y = 76
x = 76 - y
Now substitute 76-y for x in the 2nd equation...
1/3x + 1/2y = 34
1/3(76-y) + 1/2y = 34
76/3 - 1/3y + 1/2y = 34
-1/3y + 1/2y = 34 - 76/3
-2/6y + 3/6y = 34 - 25 1/3
1/6y = 8 2/3
y = 8 2/3 ÷ 1/6
y = 8 2/3 × 6
y = 52
Now substitute 52 into the 1st equation for y
x + y = 76
x + 52 = 76
x = 76 - 52
x = 24
The 2 numbers are 24 and 52.
The difference between the numbers is
52 - 24 = 28
28 difference and the numbers are 13 and 12 121 21 212 12 55 65 545 46 54 6 5 6 6666666 777.0-0000000

Answer:
Step-by-step explanation:
m=p/3
t=(3/10)(1-1/3)
t=(3/10)(2/3)=p/5
p-p/3-p/5=35
(15p-5p-3p)/15=35
7p/15=35
7p=525
p=75
So the book has 75 pages.

I don't understand the language you used
You need to use the distributive property. So you take the -9 from outside the parentheses and multiply itself by the numbers inside.
