1) The larger number is 33.
2) Joan weighs 47.5 kg, and Annie weighs 44.5 kg.
3) Ronnie walks at a rate of 4 km/h, while Margie walks at a rate of 2 km/h.
4) It takes 3 hours for Lea to do the same task working alone.
5) Katie is 5 years old and Rico is 1 year old.
To solve each problem, the following calculations must be done:
1)
(54 - 12) / 2 = X
42 / 2 = X
21 = X
21 + 12 = 33
33 + 21 = 54
2)
(92 - 3) / 2 = X
89 / 2 = X
44.5 = X
44.5 + 3 = 47.5
44.5 + 47.5 = 92
3)
1000 / 3 x 2 = 666.666
0.666 x 6 = 3.999
0.333 x 6 = 1.999
4)
1/5 + 1/X = 1/2
10/5 + 10/X = 10/2
2 + X = 5
X = 5 - 2
X = 3
5)
5 /// 1
8 /// 4

Answer:
1a - reduction
2a- enlargement
3a- reduction
4a- enlargement
Step-by-step explanation:
when the scale factor is greater than 100% it is making it larger, when less than 100% size it is making it smaller. for every answer do the original number (ex #1 would be 48 inches) and multiply it by the scale factor in decimal form, by moving the decimal over two places (ex #1 the 25% would become .25 or 1/4). therefore #1 would be an equation like 48 x 0.25= 12
Answer:
P ($1 or $5) = 5/6
Step-by-step explanation:
There are 6 $1
There are 4 $5
There are 2 $10
There are a total of 12 spaces
P ($1 or $5) = ($1 or $5)/ total
There are 6 ones and 4 fives
= (6+4)/ 12
= 10/12
Divide the top and bottom by 2
=5/6
