Answer:

see explanation below

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

but it asks months

so 3*12 and you get 36 months

Answer:

x = -1

Step-by-step explanation:

use the value of y and plug it in

2 = 2x + 4

-4. -4

-2 = 2x

divide each side by 2

-1 = x

you can plug it back in to see if it is right

Answer:

y=2x+4       y=2

2=2x+4

-4      -4

2x= -2

----   ----

2      2

x = -4

Step-by-step explanation:

CHECK:

step 1: Plug everything in.

2=2 correct   y=2x+4

                     2=2(-4)+4

                    2= -8+4

                    2= -4

                   divide 4 by 2

                     2= -2 correct      pls mark as brainliest!

Step-by-step explanation: First you make the 24 into a decimal,  you can put 2 0s to make it 24.00. Then you line up the 8.25 and the 24.00 like this   24.00

       x  8.25   then multiply away! don't bother with decimals for now. once you finish multiplying count  how many numbers are behind the decimal and move the decimal that many times.

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

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.

Answer:

240 m

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:

1. No, the shape has changed its size so it cannot be congruent.
2. Yes, shape was rotated but stayed the same shape and size so they are congruent.

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;

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.
