It is 48 b/c you multiply 8*12 which you get 96. then divide it by 2 or you can multiply it by 1/2.
Have a good day,
Den :)
For #1. Step 1: Set the equations equal to one another: (3x + 20) = (2x + 40)
Step 2: Subtract 2x on both sides of the equal sign: (3x-2x + 20) = (2x-2x + 40)
x + 20=40
Step 3: Subtract 20 on both sides of the equal sign: x + 20-20= 40-20
x=20
Step 4: plug in 20 for x: 3(20) + 20= 80 & 2(20) + 40= 80
Answer:
<
Explanation:
Step 1 - Convert the mixed numbers into decimals
7 2/5
2/5 • 20/20 = 40/ 100
40/ 100 = 0.4
0.4 + 7.0 = 7.4
Therefore, 7 2/5 = 7.4
Step 2 - Convert the mixed numbers into decimals
7 3/8
3/ 8 = 0.375
0.375 + 7.0 = 7.375
Therefore, 7 3/8 = 7.375
Step 3 - Compare
7.4 < 7.375
So, 7 2/5 is less than 7 3/8
5 because 4x + 8x is 12x and then you add 13 to 47. Lastly, divide 60 by 12x which gives you 5 :)
