A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The members of the choir decided to order from a printing company that charged $3 per shirt, plus a $50 flat fee for shipping. If the school orders 15 T-shirts how much will the total cost be?

Answer:

x = 1 and y = 1

Step-by-step explanation:

2x/y + y/x = 3

3x - y = 2

we first of all get the simple equation from the two equations and in this case we will use substitution method

3x - y = 2

then we make y the subject of the formula

y = 3x - 2

let's use y on the top equation to substitute

2x/y + y/x = 3

2x/3x - 2 + 3x - 2/x

like terms cancel

thus:

2x/1 + 1/x = 3

3x -2x = 1

x = 1

AND since we have x, we still use substitution method to find y

3x - 2 = y

3 (1) - 2 = y

3 - 2 = y

y = 1

Step-by-step explanation:

1) 2011 sum

(6+8)100

14(100) = 1400 coins collected

2) 2015 difference

(6-4)100

2(100) = 200 coin difference

3) Henry is red. just look at the points where red is ABOVE blue

2011, 2014, 2015

4) you can take your answer from one and add it to the coins collected in 2010

1400 + (4+8)100

1400 + (12)100

1400 + 1200

2600 coins

5) Chris is in blue. just look at the points where blue is ABOVE red

3 years

The reasonable probability that a white or red marble will be drawn all 180 times is; (3/10)¹⁸⁰.

Since the probability is with replacement;

Hence, the probability that a white or red ball is drawn each time is; 2+7 = 9 possible outcomes.

Hence, it follows that the probability for white or red each time is; 9/30 = 3/10

Hence, when drawn 180 times, the probability is;

Step-by-step explanation:

The numbers of new CDs is 30 and the old CDs is 21.

To solve this problem, we have to write a system of equations in which we would know the numbers of each types of CD she bought.

This is used to solve a series or complex of word problems in which we can represent in a mathematical statements;

The equations can be represented as

[tex]n + u = 51 ...equation(i)\\15n + 6u = 576 ... equation(ii)[/tex]

Let's take equation (i)

Making n the subject of formula

[tex]n + u = 51\\n = 51 - u...equation(iii)[/tex]

we can put equation (iii) into equation (ii)

[tex]15n + 6u =576\\n = 51 - u\\15(51 - u) + 6u = 576\\765-15u + 6u = 576\\collect like terms\\765-576=15u - 6u\\189=9u\\9u/9 = 189/9\\u = 21[/tex]

Let's put the value of u into equation (i)

[tex]n + u = 51\\u = 21\\n + 21 = 51\\n = 51 - 21\\n = 30[/tex]

From the calculations above, the numbers of new CDs is 30 and the old CDs is 21.

Answer:

Step-by-step explanation:

Figure is attached.

The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min.  The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).

What's the area under the graph?

The red outline forms a trapezoid.  The area of a trapezoid is  [tex]A=\frac{1}{2}h(b_1+b_2)[/tex]  where the b's are the lengths of the two parallel base and  h  is the height (the distance between the bases).

Reading the graph carefully (notice the scales!)...

Answer: 21

Step-by-step explanation:

Add 3 to both sides so then it would be -7/3x=-49

Then multiply the reciprocal of -7/3 which is -3/7 to both sides

It would then be x=-49 times -3/7 and if you simplify that it becomes 21

Answer:

5.1

Step-by-step explanation:

multiply the length value by 2.54

2x2.54=5.08, which rounds to 5.1

if the given length is 2 inches. The obtained length in the centimeter will be 5.1 cm to the nearest tenth.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that, the length is 2 inches.

We have to convert the given length is in centimeters,

As we know,1 inch consists of 2.54 cm.

1 inches = 2.54 cm

So for 2 inches, we have to multiply the obtained data by 2 as,

2 inches = 2.54 × 2

2 inches = 5.08 cm

The obtained value to the nearest tenth will be 5.1 cm.

Thus, if the given length is 2 inches. The obtained length in the centimeter will be 5.1 cm to the nearest tenth.
