Answer:
D
Step-by-step explanation:
So here we have a line plot that shows lengths of insects and the quantity of insects that fits the description.
For instance, there are 4 Xs for 1/8. This means that there are four insects that are 1/8 inches long. Likewise, there is only 1 X for 7/8. This means that are is only one insect that is 7/8 inches long.
To find out how much longer is the longest insect than the shortest insect, we simply need to subtract the shortest into the longest.
The longest insect we have is the lone insect who is 7/8 inches long.
And the shortest insects we have are the four insects who each measure 1/8. However, we only need 1.
So, subtract:
Combine fractions with common denominators:
Subtract:
The answer is D.
Step 1:
Line up respective variables in column.
.................(1)
.................................(2)
Step 2:
We need to multiply first equation with -2 so that the coefficient of b becomes equal and opposite of -8.
*2
...................(3)
Step 3:
Add equation (2) and (3)
The b terms will cancel out and we are left with only a terms.
-11a = 22
dividing both sides by -11
a=-2
Step 4:
plug this value of a in equation (1) to find value of b,
b=-9
Answer : a=-2 and b =-9
