The question does not seem complete, but I'll represent the statement mathematically and look for their ages each. This is because the worst they can ask for is their ages.
Let C stand for Courtney's age, A for Andrei's age, N for Natalie's age and S for Shari's age. From the question we can deduce the following:
C = 2A
C = N + 3
C = S/2
S - N = C + A
S = 2C, N = C - 3 and A = C/2, therefore we have
2C - (C - 3) = C + C/2
C + 3 = C + C/2
C/2 = 3 and C = 6
A = C/2
A= 6/2
A = 3
N = C - 3
N = 6 - 3
N = 3
S = 2C
S = 2 x 6
S = 12.
C = 6, A = 3, N = 3 and S = 12
Answer:
1. 12
2. 32
3. 8
4. 1
5. 14
Step-by-step explanation:
The above numbers represent the empty boxes from top to bottom.
1. (.4 +1.6) = 2 x 6 = 12
2. (24 ÷ 3 x 4) = 8 x 4 = 32
3. 8 ÷ (9-5) + 3 x 2. You have to remember Order of Operations on this one.
8 ÷ 4 + 3 x 2
2 + 6 = 8
4. 28 ÷ 7 x 1/4
4 x 1/4 = 1
5. (6 x 5) - (4 x 4)
30 - 16 = 14
hope this helps, brainliest is always appreciated.
Answer:
200 m
-15 m
215 m
Step-by-step explanation:
Given :
Top of hill = 200 m above sea level ; height of hill top is positive 200m = 200 m
Bottom of lagoon = 15m *below sea level ; bottom of lagoon = - 15m
We have related the height of the two points with respect to sea level ; points above sea level are represented as positive ; points below are represented as negative.
Difference between the two heights :
Hill top - bottom of lagoon :
200 m - (-15) m
200 m + 15 m
215 m
Difference between the heights is 215 m
First ne is 3x then 2x then 26x
