Answer:
1 13/24
Step-by-step explanation:
First we need to find the LCD (lowest common Denominator) which will be 24. When we multiply 8 x 3 = 24 we will also multiply 5 by 3 which equals 15. So 5/8 = 15/24. Then we multiply 12 x 2 = 24, and again we also multiply the numerator by the same number which is 11 x 2 = 22. So 11/12 = 22/24.
Now that we have the LCD then we can add up the two. So 15/24 + 22/24 = 37/24. Now we need to simplify that to 1 13/24. Thank you.

Answers
Answer:
x = 63
Step-by-step explanation:
Step 1: Multiply both sides by 7/5.
[tex]45 *\frac{7}{5}=\frac{5}{7}x*\frac{7}{5}[/tex] [tex]63 = x[/tex]Step 2: Check if solution is correct.
[tex]45 = \frac{5}{7}(63)[/tex] [tex]45 = 5 * 9[/tex] [tex]45 = 45[/tex]Therefore, x = 63.
x = 63
Step-by-step explanation:45 = 5/7x
=> 9 = x/7
=> x = 63.

the serving size for a toddlers daily vitamin c is 3/4 cup of orange juice. if there are 2 1/4
cups of orange juice how many servings of vitamin c are there for a toddler
Answers
To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .
2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4
9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings
Answer:
Three servings
To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .
2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4
9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings

A textbook company sells teacher editions
and student editions in package deals.
Each package includes 3 teacher editions
for every 65 student editions. Which
combination could a school order?
A.
9 teacher to 260 student editions
B. 12 teacher to 325 student editions
12 teacher to 260 student editions
Answers
Answer:
C. 12 teacher editions and 260 student editions
Step-by-step explanation:
We can use division to solve this problem
65 ÷ 3 = 21.66... we can round this to 22 student ones we get 1 teacher copy.
A. 260 ÷ 9 = 28.99... we can round to 29 students ones we get 1 teacher copy so this one isn't correct.
B. 325 ÷ 12= 27.083... we can round to 27 students ones we get 1 teacher copy so this one isn't correct.
C. 260 ÷ 12 = 65 ÷ 3 = 21.66... we can round this to 22 student ones we get 1 teacher copy so this option is correct
C

(2x+1)(x+5)
6x-4xy
16x^2-25
Answers
Step-by-step explanation:
i believe what you need help on is simplifying the equations. so let's start with the first one.
====================================================================
(2x+1)(x+5) original problem
(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.
2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.
2x2+11x+5 this is the most simplified equation.
====================================================================
6x−4xy original problem.
unlike the last problem, we can easily just... 6x + (−4xy).
−4xy+6x this is the most simplified equation.
====================================================================
ok, the last one. phew!
unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.
if we factored, we would get...
(4x+5)(4x−5)
===================================================================

Keith will run at most 26 miles this week. So far, he has run 14 miles. What are the possible numbers of additional miles he will run? Use t for the number of additional miles he will run. Write your answer as an inequality solved for t.
Answers
Answer:
[tex]t \leqslant 12[/tex]
Step-by-step explanation:
We know that Keith has ran 14 miles already, and he's aiming to reach no more than 26 miles, this week.
So we can put:
[tex]14 + t \leqslant 26[/tex]
Since, 14 is the number we know, t represents the number we have yet to find, and 26 is the product of this inequality. (We use the less-than-or-equal-to sign, because Keith is only aiming for 26 or less miles.)
Now we solve:
Subtract 14 on both sides to get
[tex]t \leqslant 12[/tex]
So t is less-than-or-equal-to 12, meaning Keith has 12 or less miles to run in order to reach 26 miles.
Hope this helps :)

Round 681,858 to the nearest hundred thousand
Answers
Answer:
700,000
Step-by-step explanation:
So really, in this question, all you care about is the 10,000ths place
The 10,000ths place in this number is 8. Since 8 is greater that four, round up to 700,000
Answer:
700,000
Step-by-step explanation:
Round off all the numbers after the first number
If rounded off and the number closest to the first no is 5 and above, it automatically approximates the next number to its left.
Example: 681,858
The last no is 8, it therfeore approximates 5, thereby changing it to a 6
After being changed to a 6, it approximates the next no to its left, 8, turning it into a 9, nine approximates 1, turns it to a 2, two can't approximate, it's below 5, move on to 8, eight approximates 6 turning it to a 7, that's how I got my 700,000.
