So 2e:3t 3t+15=1e:3e so
2e:3t
3t+15
1e:3t
1e:3t=2e:6t
so 2e:6e
2e:3t+15=2e:6t
15=3t
t=5
2+3=5 units
5 times 5=25
he made 25 samiches in all
check
e:t=10:15=2:3
15+15=30
10:30=1:3
checks
he made 25 sammiches origonaly
Answer:
See below ~
Step-by-step explanation:
<u>(a) Mean of the data</u>
- 2.4 + 1.6 + 3.2 + 0.3 + 1.5 / 5
- 9/5
- <u>1.8</u>
<u></u>
<u>(b) New mean after each data point increased by 10</u>
- 12.4 + 11.6 + 13.2 + 10.3 + 11.5 / 5
- 59/5
- <u>11.8</u>
<u></u>
<u>(c) New mean after each data point doubled [from (b)]</u>
- 24.8 + 23.2 + 26.4 + 20.6 + 23 / 5
- 118/5
- <u>23.6</u>
Answer:
False
Step-by-step explanation:
Multiply 8 by 2 to create the common denominator (which is 16).
Now multiply 4 by 2 to keep the fraction even.
This gives you the fraction 8/16 which is not equivalent to 10/16.
Another way you could write this inequality:
8/16 < 10/16
It should be negative one (-1)
