Answer:
1 and 3
Step-by-step explanation:
since they both are equal shape with equal sizes.
$25 times 45 equals $1125. Twice as many students as adults so, 45x2=90 90x$12= $1080 $1125+1080=$2205
Answer:
B
Step-by-step explanation:
So, to figure this out, we must find the total miles Maria ran in a week.
We know that she ran 2.75 miles each day.
She did this for 7 days.
Her goal was 17.5 miles.
So first, multiply the amount of days by the amount of miles per day:
7*2.75
=
19.25
So now we know that she ran a total of 19.25 miles in a week.
Since she onlu needed to run 17.5 miles, we can instantly rule out:
A - Runs less 17.5 miles
C - Runs exactly 17.5 miles
This leaves:
B - She runs 1.75 miles more than 17.5 miles
D - She runs 2.75 miles more than 17.5 miles
To figure out which on is correct, subtract her total miles by her goal:
19.25-17.5
=
1.75
So we know it must be:
B - She runs 1.75 miles more than 17.5 miles
This is because we figured out she ran an extra 1.75 miles.
Hope this helps! :)
Simple....
we know the formula you need to use is y=mx+b....
plug 'n chug....
3=3(1)+b
3=3+b
-3 -3
b=0
Thus.....y=3x
Thus, your answer.
D. 8 mm by 10 mm by 4 mm
20 mm by 8 mm by 2 mm
8 x 10 x 4 = 320 mm
20 x 8 x 2 = 320 mm
