**Answer:**

Option D. (120, 80, 40)

**Step-by-step explanation:**

Let the cost of 3 baseball cards bought by Andrew are $x, $y and $z.

Now we will form the equations to find the unknown values of x, y, and z.

**Statement 1** - Andrew bought 3 baseball cards for $240

Equation will be **(x + y + z) = 240 --------(1)**

**Statement 2** - Jack offered a deal to buy the first card for the double of its original value along with the second card for $320.

Equation will be **2x + y = 320 --------(2)**

**Statement 3** - Jack offered another deal to buy first card for the double of its original value along with third card for $280

Equation formed** 2x + z = 280 ------(3)**

Now we can solve these equations to get the values of x, y and z.

**From equation 2**

y = 320 - 2x

**From equation 3**

z = 280 - 2x

Now we can replace the values of y and z in equation number 1.

Equation 1 becomes after substitution of y and z values

x + (320 - 2x) + (280 - 2x) = 240

Now we will group the similar terms

(x - 2x - 2x) + (320 + 280) = 240

-3x + 600 = 240

-3x = 240 - 600

-3x = - 360

x =

x = 120

Now we put x = 120 in the value of y

y = 320 - 2x

y = 320 - 2×120

= 320 - 240

= 80

Similarly we put the value x = 120 in value of z

z = 280 - 2x

= 280 - 2×120

= 280 - 240

= 40

So the original values of 3 baseball cards are (120, 80, 40)

**Option D**. will be the answer.

__Answer__

40%

__Explanation__

A parentage value is a value that has been compared to 100.

Percentage = (change in the value)/(the original value) × 100%

= (35-25)/25 × 100%

= 10/25 × 100%

= **40%**

35 Percent of 70 is 24.5

We assume, that the number 70 is 100% - because it's the output value of the task. We assume, that x is the value we are looking for. If 70 is 100%, so we can write it down as 70=100%. We know, that x is 35% of the output value, so we can write it down as x=35%. Now we have two simple equations: 1.)70=100% 2.)x=35%where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that: 70/x=100%/35% Now we just have to solve the simple equation, and we will get the solution we are looking for.

**Answer:**

105%.

**Step-by-step explanation:**

We are asked to convert 1.05 to a percent.

To convert a decimal to percent, we simply multiply the decimal number by 100 and add a percentage sign.

Let us multiply 1.05 by 100.

**Therefore, 1.05 as a percent would be 105%.**

**Option B, 39.62%**

**Step-by-step explanation:**

We have to find 84 is what percent of 212.

For this we will put 84 in the numerator and 212 in the denominator to find the fraction first.

Then we will multiply this fraction by 100 to get the percentage.

Fraction of 84 to 212 =

=

Now the percentage will be

= 39.62%

**Option B, 39.62%** is the correct answer.

Hi there!

First, for any of the five cards being drawn, there is a **1/5 **chance, or 20%. So, the probability of a red card being drawn is **1/5. **Then, since the card is not replaced, it becomes a **1/4, or 25%**, chance of any card being drawn (besides red). So, the probability of a blue card being drawn is **1/4. **So in order to find what the question is asking, we'll need to multiply the two fractions together.

1/5 x 1/4 = 1/20

1/20 = 5%

Therefore, the correct answer is **5%**, or the second option.

Hope this helps!! :)

**Answer:**

C. The college spread is best described by the IQR. The high school spread is best described by the standard deviation.

**Step-by-step explanation:**

If data is normally distributed we use Standard deviation otherwise we use Interquartile Range (IQR) for measuring the spread.

Further, data is said to be normally distributed if Mean = Median = Mode.

So, High School data is normally distributed but College data is not.

So, We measure the spread of College data by IQR and High School data by Standard Deviation.

**Thus, Option C is the only correct option.**

QUESTION POSTED AT 18/01/2020 - 11:47 AM

The *correct answer* is:

The first equation should be multiplied by 7 and the second equation by −6.

**Explanation**:

We are told we want to eliminate the x-terms. This means the coefficients should be the same.

It will also be easier if one is positive and one is negative.

The x-coefficient of the first equation is 6 and the x-coefficient of the second equation is 7. In order to have the same coefficients, we should try to make both of them equal 42 (this is the least common multiple, or LCM, of 6 and 7). To do this, multiply the first equation by 7 (6*7 = 42) and the second one by 6 (7*6 = 42). Additionally, to make the second equation negative, we will multiply it by a negative, so -6.

x1 , y1 = 38 , 30

x2 , y2 = 14 , 20

Distance S = [ (20-30)^2 + (14-38)^2 ] ^0.5

An identity is obtained when you substitute any value of x to an equation, both sides will give out the same answer. A trial-and-error method is best used for questions like these. The method is shown below:

Let: 1 = m = y = v = w

A. 7m – 2 = 8m + 4 – m

7(1) – 2 = 8(1) + 4 – (1)

5 =/= 11

B. 8y + 9 = 8y – 3

8(1) + 9 = 8(1) - 3

17 =/= 5

C. 11 – (2v + 3) = –2v – 8

11 - (2(1) + 3) = -2(1) - 8

6 =/= -10

D. 5w + 8 – w = 6w – 2(w – 4)

5(1) + 8 -1 = 6(1) - 2(1 - 4)

12 = 12

Therefore, the choice D is the identity.

Let: 1 = m = y = v = w

A. 7m – 2 = 8m + 4 – m

7(1) – 2 = 8(1) + 4 – (1)

5 =/= 11

B. 8y + 9 = 8y – 3

8(1) + 9 = 8(1) - 3

17 =/= 5

C. 11 – (2v + 3) = –2v – 8

11 - (2(1) + 3) = -2(1) - 8

6 =/= -10

D. 5w + 8 – w = 6w – 2(w – 4)

5(1) + 8 -1 = 6(1) - 2(1 - 4)

12 = 12

Therefore, the choice D is the identity.
