I'm so confused can someone help me with number 4 - 1

Answers

Answer 1
Answer: Ok so first with a you have 
a=2 b=5 c=7
and the problems are 2a+10 and 2b+c
Well to do this we are going to right 2a+10 as 2*a+10
So now lets replace a.
and since a=2 we have 2*2+10
2*2=4+10=14
So A is 14
and now for be we have 2b+c
Lets re-write it as 2*b+c
and now replace
2*5+7
2*5=10+7=17
b is 17.
Now with the next (4)
For a it is x=7
Subtract 3x from both sides.
Subtract 5 from both sides.
x=7
and for B
x=3
Subtract 3x from both sides.
Add 10 to both sides.
Divide both sides by 4.
x=3
Hope this helps!

Answers

Hello!

You are finding the probability that you will roll a number greater than 10

You do this by doing the amount of favorable outcomes over the total amount of outcomes

There are 2 numbers greater than 10

There are 12 total numbers

This is a probability of 2/12

2/12 = 0.17

The answer is A)0.17

Hope this helps!
Total number of possible outcomes = 12
Total number of favourable outcomes (i.e. greater than 10) = 2

P(greater than 10) = 2/12 = 0.17

Answer: 0.17

a baseball team played 35 games and won 4/7 of them how many games were won and how many games are lost?

Answers

you need to make the denominator of the fraction equal 35, and 35/7 = 5

multiply 4/7 by 5 to get 20/35

they won 20 out of the 35 total games, and therefore lost 15 games

2. 300 mph or nautical miles or Knots
3. 77 miles
4. 150 minutes 
5. 270 miles
6. 20 yd per min.
7. 1200 miles
8. 14 ft. per min.
9. 2 hours.
10. 3 hours max. (unless u count traffic)
11. No, it will take 3 hours and 30 minutes.

easy, if you use your head and a shortcut

d=rt
d/r=t
d/t=r
basically if given 2 of the, you can find the rest with
d=rt
t=d/r
r=d/t


2. speed=r
d=3600m
t=12
r=d/t
r=3600m/12m
r=300m/min
rate=300m per minute


3.  the time is 7 hours
speed =11mph=r
d=rt
d=7h times 11mph
d=77miles



4. given
d=300cm
r=2cmpermin
t=d/r
t=300cm/2cmpermin
t=150min


5. r=45mph
t=6h
d=rt
d=45mph times 6h
d=270miles


6. d=400yd
t=20min
r=d/t
r=400yd/20min
r=20yd/min
r=20yards per minute


7. r=120mph
t=10h
d=rt
d=120mph times 10h
d=1200miles

8. d=700ft
t=50min
r=d/t
r=700ft/50min
r=14ft/min
r=14 feet per minute


9. d==1200mi
r=600mph
t=d/r
t=1200mi/600mph
t=2h
t=2 hours


10. speed limit is 65mph=r
d=195miles
t=?
t=d/r
t=195mi/65mph
t=3 hours

11. 2 ways
1. find how far it travels in 4 hours
2. find how long it will take
both easy, I willl do first

in 4 hours
d=rt
d=4h times 65mph
d=260 miles
260mi>230mi
yes
