Answers
Answer: 8 1/4 miles
Step-by-step explanation:
I think your question isn't well written and should be:
Nathan jogged 2 1/4 miles on Monday. On Wednesday, he jogged 3 1/3 miles and on Friday, he jogged 2 2/3 miles. How far did Nathan jog altogether?
This will be:
= 2 1/4 + 3 1/3 + 2 2/3
= 2 3/12 + 3 4/12 + 2 8/12
= 7 15/12
= 7 + 1 3/12
= 8 3/12
= 8 1/4 miles

In two weeks, your class collected more than 380 cans of food for the annual food drive. In the first week, 145 cans were collected. How many cans c of food were collected in the second week? Write and solve an inequality.
145 + c < 380; c < 235
c + 145 > 380; c > 525
c − 145 ≥ 380; c ≥ 525
145 + c > 380; c > 235
Answers
Answer:
Step-by-step explanation:
145+c>380 subtract 145 from each side
c>235 so the answer is
145+c>380; c>235

A bag contains 7 red marbles, 3 blue marbles and 6 green marbles. If two
marbles are drawn out of the bag, what is the probability, to the nearest ioth
of a percent, that both marbles drawn will be red?
Answers
Answer:
42%
Step-by-step explanation:
figure probability of the first:
7+6+3=16
7/16=0.44
figure probability of the second:
6/15=0.40
find the average:
0.44+0.4=0.84
0.84/2=0.42
convert from decimal to fraction:
42%!
The solution is , 42% is the probability, to the nearest 10 th of a percent, that both marbles drawn will be red.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
A bag contains 7 red marbles, 3 blue marbles and 6 green marbles. If two marbles are drawn out of the bag.
we have,
figure probability of the first:
7+6+3=16
7/16=0.44
figure probability of the second:
6/15=0.40
find the average:
0.44+0.4=0.84
0.84/2=0.42
convert from decimal to fraction:
42%
Hence, The solution is , 42% is the probability, to the nearest 10 th of a percent, that both marbles drawn will be red.

A line that is parallel to the line y=3x-8 and passes through the point (-1,6)
The equation of the parallel line is...
Answers
Answer:
y = 3x + 9
Step-by-step explanation:
If the line is parallel, that means it will have the same slope. So, the line will also have a slope of 3.
Using y = mx + b, plug in the slope and given point, and solve for b:
y = mx + b
6 = 3(-1) + b
6 = -3 + b
9 = b
Plug in the slope and b into y = mx + b
y = 3x + 9
So, the equation of the parallel line is y = 3x + 9
