Use the percent proportion
21 x
—— = ——
100 300
to solve :
21 x 300 = 6300
6300 ÷ 100 = 63
Answer = 63 of Elmer’s shells are fossilized snail shells :)
Answer:

Step-by-step explanation:
1. AB:BC is 1:2
2. Add the 1 and the 2
(3)
3. Find the distance between -7 and 26
26-(-7) = 33
4. Divide the distance by 3
33/3 = 11
5. Find the distance from A---->B
-7 + 11 = 4
Answer:
The numbers are 36 and 42
Step-by-step explanation:
Represent the two numbers by m and n, m being the larger number and n the smaller. Then
m = n + 6. also, 7n = 6m
Substitute n + 6 for m in the second equation: 7n = 6(n + 6).
Performing the indicated multiplication, we get 7n = 6n + 36, or n = 36.
Then m = n + 6, which here is m = 36 + 6 = 42.
The numbers are 36 and 42.
Answer:
let's say the item bought costs £20
sales tax first
20/100 X 7.5 = 1.50. 20 + 1.50 = 21.50
21.50/100 X 20 = 4.30
21.50 - 4.30 = £17.20
discount first
20/100 X 20 = 4
20 - 4 = 16
16/100 X 7.5 = 1.20
16 + 1.20 = £17.20
it wouldn't matter
Answer:
yes
Step-by-step explanation:
you find the area by multiplying 38 X 112= 4,256
