Answer:
The expression is half the value of (10 + 12)
Step-by-step explanation:
We see the top part is 10 + 12
The whole thing is a fraction and 2 is in the denominator
You divide your term by your denominator, and diving by 2 is the same as 1/2 if a term.
Answer:the first one is ten And the last one is the first one on top
Step-by-step explanation:
Answer:
The dependent variable = Number of homeruns
Independent variable = years played
The Independent variable is Number of characters per minute
Dependent variable is Texting speed
Step-by-step explanation:
The independent variable are the variables which are used to infer or being about changes to the dependent variable by supplying different values of them, they are also called predictor variables. By varying the number of years, a baseball players' number of homeruns' can be predicted in such basis, hence, the
predicted or dependent variable is the number of homeruns'.
Similarly, the Number of characters (independent) an individual is able to type within a particular period of time can be used determine the Texting speed (dependent) of such person.
1. 26.75 = 3s + 5(s - 2.50)
2. 3a - 0.3(a + 50) = 75
3a - 0.3a - 15 = 75
3a - 0.3a = 75 + 15
2.7a = 90
a = 90/2.7
a = 33.3 <===
It can be done.
You must take a few steps to set it up, but then you are able to count 7 minutes. The setup makes you be able to time 2 minutes on the 5-minute sandglass and then you do another 5 minutes on the same sandglass.
Setup:
Start both sandglasses at the same time. When the 5-minute sandglass runs out, the 8 minute sandglass has 3 minutes of sand left. At this moment, start the 5 minute sandglass again.
When the 8-minute sandglass finishes the remaining 3 minutes, the 5-minute sandglass has 2 minutes left.
Actual timing of 7 minutes:
Let the 2 minutes pass, and immediately turn over the 5-minute sandglass to count an addition 5 minutes. The last 2 minutes of the 5-minute sandglass plus an additional 5 minutes of the 5-minute sandglass add to 7 minutes.
