Answer:

Step-by-step explanation:

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

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).

Answer:

x = 17

Step-by-step explanation:

Since its a right triangle, you can use Pythagorean Theorem.

8² + 15² = x² (Given)

64 + 225 = x² (Simplify)

289 = x² (Add like terms)

17 = x (Square root both sides)

Answer:

6/3 is 2. That's the total cost of each pencil.

Step-by-step explanation:  

The required mean absolute deviation of the number of goals is 0.8.

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.

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.

Answer:

Step-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

Answer:

Step-by-step explanation:

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.

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

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 solution of the equation 2(4-3x)+5(2x-3) = 20-5x+9 is 3.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 2(4-3x)+5(2x-3) = 20-5x+9

x is the variable in the equation.

Plus and minus are the operators

Apply distributive property.

8-12x+10x-15=20-5x+9

Take the variable terms on one side and constants on other side

5x-12x+10x=20-8-15+9

3x=6

Divide both sides by 3

x=2

Hence, the solution of the equation 2(4-3x)+5(2x-3) = 20-5x+9 is 3.
