Answer: -28
7/2=3.5
3.5x-8=-28
The answer is a. you can see this because 1/3+1/3 gives you 2/3 and 1+1 gives you 2. when you add these two numbers together, it gives you mikayla’s total number of miles at 2 2/3.
bearing in mind that 1Kg ≈ 2.2lbs.
so, if a baby is say 2.2lbs, and then it doubles in weight, to 4.4lbs.
well, we know when the baby was 2.2lbs it was exactly 1Kg, but when it went up to 4.4lbs, is it 2Kgs? well, yes, 2Kgs = 2.2 + 2.2 or 2(2.2).
so, multiplying the lbs value by some factor, will retain the Kg:lbs ratio.
Using the y=mx+b method and y1-y2/x1-x2
it would look like this
6-10=-4
divide
2-4=-2
and m=2 (slope)
then using y=mx+b
plug n chug
6=2(2)+b
6=4+b
b=2
thus, your equation is
y=2x+2
Answer:
42
Step-by-step explanation:
The correct choice is marked.
If you follow instructions, you will compute the quotient for each value in the set:
2520 ÷ 30 = 84
2520 ÷ 42 = 60 . . . . . the value we're looking for (we need go no further)
2520 ÷ 84 = 30
__
The easier way to solve the problem is to multiply the equation by x/60, so you have ...
2520 ÷ 60 = x
Then, you're doing one division instead of two or three.
2520 ÷ 60 = 42 = x
