Only add 1 and 5 first, then your denominator would be 32 because 8 times 4 is 32.

The answer is 7/8. First, I found common denominators of 32. Then I multiplied 1*8 and got 8 so 1/4 is equal to 8/32. Then I multiplied 5*4 and got 20 so 5/8 is equal to 20/32. Then I added 20 and 8 and got 28. So 1/4+5/8 equals 28/32 but then you simplify by finding the common factor of 4 so u divide 28 by 4 which is 7 and then you divide 32 by 4 which is 8 so your answer is 7/8.

Ann, Chang, and Kareem sent a total of

Gnoma [55]

It is given in the question that

Ann, Chang, and Kareem sent a total of 89 text messages over their cell phones during the weekend. Ann sent 9 fewer messages than Chang. Kareem sent 3 times as many messages as Ann.

Let number of messages Chang sent be x. And Ann sent 9 fewer than Chang, so Ann sent (x-9) messages. And Kareem sent 3 times as many messages as Ann, so Kareem sent 3(x-9) messages.

And the total messages are 89. That is

$x+x-9+3(x-9)=89$

Combining like terms

$x + x - 9 + 3x-27 =89
\\
5x -36=89
\\
5x = 125
\\
x =25$

So Chang sent 25 messages, Ann sent

$25-9=16 messages$

And Kareem sent

$3*16 = 48 messages$

4+2(7)= 62+8×3= 3(2+5)−5(3)+8= 24−6+12÷2×3=

Temka [501]

4+2(7)= 18

62+8x3= 86

3(2+5)-5(3)+8= 14

24-6+12÷2x3= 36

Hope this helps you! :D

7 2\3+ (5 1\6-1 5\9)

lorasvet [3.4K]

Start off with: 5 1/6 - 1 5/9
turn it into an entire fraction: 31/6 - 14/9
make a common denominator (which is 18): 93/18 - 28/18 = 93 - 28 = 65/18
65/18 + 7 2/3 is the new equation
7 2/3 = 23/3
23/3 = 138/18
65/18 + 138/18 = 203/18
Simplify: 203/18 = 11 5/18
Answer: 11 5/18
