Note that subtracting a negative number from another number is equivalent to adding the magnitude of the negative number to the other number. Thus,
subtracting -1 2/3 from 5 1/2 is equivalent to adding 1 2/3 to 5 1/2.
Here the LCD is 3(2) = 6. Let's add 1 4/6 to 5 3/6. We get 6 7/6, or more properly, 7 1/6 (answer).
12+5=x+8
add 12 and 5
17=x+8
subtract 8 from both sides
9=x
Answer:
A. 56
Step-by-step explanation:
Since a parallel line is 180 degrees, all we do is x + x+68 = 180.
2x = 112 or x = 56
Step-by-step explanation:
step 1. add the ratio part
1+2=3
step 2. use answer from step 1 and divide
54/3 is 18
step 3. use 18 into both of the mice
brown: 18*1 is 18 brown mice
. Gray: 18*2 is 56 gray mice
There fore there are 56 gray mice
