Which expressions are equivalent to 2(b + 3c) ?
A: 3(b+2c)
B: (b + 3c) + (b + 3c)
C: 2(b) + 2(3c)
Answers
B. (b+3c)+(b+3c)
C. 2(b)+2(3c)
Step by Step instruction :)))
we have
2 (b+3c)
Distribute the number 2
2(b+3c) = 26 + 2(3c) = 26 + 6c
Verify each case
Case A) 3(b+2c)
distribute the number 3
3(b + 2c) = 36 + 3(2c) = 36 + 6c
3b + 6c is NOT equal to 2b + 6c
therefore
Choice A is not equivalent to the given expression
Case B) (b+3c)+(b+3c)
Combine like terms
b + 3c) + (b + 3c) = (b + b) = 3c + 3c = 26 + 6c
2b + 6c = 26 + 6c
therefore
Choice B is equivalent to the given expression
Case C) 2(b)+2(3c)
Multiply both terms by 2
2(b) + 2(3c) = 2b + 6c
2b + 6c = 26 + 6c
therefore
Choice C is equivalent to the given expression

Terry sees this offer refurbished phone 35% off now only £78 how much was the phone before the discounted price
Answers
Answer:
the price before the discounted price is £120
Step-by-step explanation:
The computation of the price before the discounted price is shown below:
After giving 35% off the price is £78 that means it is 65% value
So we have to determine the 100% value
So,
= £78 × 1 ÷ 0.65
= £120
Hence, the price before the discounted price is £120

An express train travelled at a certain average speed from Town X to Town Y which was
150 km away. It then continued its journey to Town Z at an average speed 20 km/h faster than
its initial average speed. Town Ywas 200 km from Town Z. If it took the same time to travel for
both parts of the journey, what was the train's average speed for the first part of the journey?
Answers
Answer:
60 km/hr
Step-by-step explanation:
Let the speed at the initial average speed from Town X to Town Y be a.
We are told that it journeyed to Town Z at an average speed 20 km/h faster than its initial average speed. Thus, its average speed here is (a + 20) km/hr.
Town Y was 200 km from Town Z.
Thus, time spent here is;
t_2 = 200/(a + 20)
Time from X to Y is; t_1 = 150/a
We are told that it took the same time to travel for both parts of the journey.
Thus; t_1 = t_2
150/a = 200/(a + 20)
Cross multiply to get;
150(a + 20) = 200a
150a + 3000 = 200a
200a - 150a = 3000
50a = 3000
a = 3000/50
a = 60 km/hr

The cost of renting a boat at a lake is $35 per hour plus $5 for life jackets. Write an
• equation in slope-intercept form that can be used to calculate the total amount you would pay for
renting a boat. (assume only you need a life jacket)
Answers
Answer:
y = 35x + 5
Step-by-step explanation:
Slope-intercept form is y = mx + b
m is the slope, b is the constant, or y-intercept.
In this case, 5 is our constant. You pay a one-time fee of $5 for a life jacket. This price doesn't change nor do you have to pay it again, so this is your constant.
35 is our slope. 35 represents the $35 you pay for each hour with the boat. This is our slope because it will change overtime, based on x, or the number of hours you are renting the boat.
y is the total cost, since you have to add up $35 times the number of hours you are renting, plus the $5 for the life jacket.

The ratio of boys to girls in a group is 7:2. If there are 60 more boys than girls, work out how many girls there are.
Answers
Answer:
Step-by-step explanation:
So, kids are divided into 8 total parts.
7 - 1 = 6 more parts that are boys. The 48 extra boys are those 6 parts.
48/6 = 8 boys per part
All parts have the equal number of kids, so one part girls also has 8.
There are 8 girls (and 56 boys. 8:56 = 1:7).

Answers
Answer:
The question you posted was a bit confusing for me, but I'm assuming that you want the simplified ratio of the number of white marbles to the number of green marbles.
The answer would be 8:3.
Step-by-step explanation:
There are 8 white marbles and 3 green marbles, so you get 8:3. And since 8 and 3 are relatively prime, no simplifying is needed.
The answer is 8:3.

You are printing out information packets for your company. You will need a total of 6,400 pages to complete all of the packets. How many reams of 500 pages each will you need in order to print out all of these packets?
Answers
Answer:
13 reamsStep-by-step explanation
Given
Total number of pages to complete the packet = 6400 pages
If each ream contains 500pages, then:
Total number of reams needed = Total pages/number of pages per ream
Total number of reams needed = 6400/500
Total number of reams needed = 12.8
Hence you will need about 13 reams for all the packets

a hockey team scored the following number of goals in their last 5 games: 2,3,5,3,2 which is the mean absolute deviation of the number of goals?
Answers
The required mean absolute deviation of the number of goals is 0.8.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
The mean absolute deviation of the number of goals is a measure of how far the individual scores deviate from the mean (average) score.
To find the mean (average) score:
Mean = (2 + 3 + 5 + 3 + 2) ÷ 5 = 15 ÷ 5 = 3
Next, we find the absolute deviation for each score:
Absolute deviation for score 2: |2 - 3| = 1
Absolute deviation for score 3: |3 - 3| = 0
Absolute deviation for score 5: |5 - 3| = 2
Absolute deviation for score 3: |3 - 3| = 0
Absolute deviation for score 2: |2 - 3| = 1
Mean absolute deviation is given as,
= (1 + 0 + 2 + 0 + 1) ÷ 5 = 4 ÷ 5 = 0.8
So, the mean absolute deviation of the number of goals is 0.8.
