jerry bought 5 candy bars for $14.75. if the king size candy bar cost $3.75 and a regular size candy bar cost $1.75, how much of each candy bar did he buy?
one equation looks like:

3.75x+1.75y=14.75

Answers

Answer:

King size(x): 3

Regular size(y): 2

Steps:

System of Equations:

x+y = 5

3.75x+1.75y = 14.75

Multiply 3.75 on all sides.

3.75x+3.75y = 18.75

3.75x+1.75y = 14.75

Subtract top and bottom

            2y  = 4

            /2      /2

             y   =  2

After you know regular size amount, figure out king size ----3.

-3x - 4y = 5

Answers

Answer:

x = 1  ,y = -2

Step-by-step explanation:

Solve the following system:

{-4 y - 3 x = 5 | (equation 1)

3 y - 2 x = -8 | (equation 2)

Subtract 2/3 × (equation 1) from equation 2:

{-(3 x) - 4 y = 5 | (equation 1)

0 x+(17 y)/3 = -34/3 | (equation 2)

Multiply equation 2 by 3/17:

{-(3 x) - 4 y = 5 | (equation 1)

0 x+y = -2 | (equation 2)

Add 4 × (equation 2) to equation 1:

{-(3 x)+0 y = -3 | (equation 1)

0 x+y = -2 | (equation 2)

Divide equation 1 by -3:

{x+0 y = 1 | (equation 1)

0 x+y = -2 | (equation 2)

Collect results:

Answer: {x = 1  ,y = -2

In the figure below, points J, K, and L are the midpoints of the sides of AXYZ.

Suppose JK=38, X2=96, and YX=56.
Find the following lengths.

Answers

Answer:

28 ; 76 ; 38

Step-by-step explanation:

KL = [tex]\frac{XY}{2}[/tex] = [tex]\frac{56}{2}[/tex] = 28 units

YZ = 2 × JK = 38 × 2 = 76 units

LZ = 76/2 = 38 units

The lengths are: KL =  28 units, YZ = 76 units and LZ= 38 units.

What is Mid point theorem?

The line segment in a triangle connecting the midpoint of two sides of the triangle is said to be parallel to its third side and is also half the length of the third side, according to the midpoint theorem.

Given:

J, K, and L are the midpoints of the sides of ΔXYZ.

JK=38, X2=96, and YX=56.

Now, using Mid point theorem

JK= 1/2 YZ

38 = 1/2 YZ

YZ= 2 x 38

YZ = 76 units.

and, KL= 1/2 YX

KL = 1/2(56)

KL= 28

LZ = 1/2 (YZ)

LZ = 1/2(76)

LZ = 38 units

Decide whether the pair of lines is parallel, perpendicular, or neither.
Ly: 2x + 3y = 8
L2:3x + 2y = 7
Choose the correct answer below.
A. The lines are neither parallel nor perpendicular.
B. The lines are perpendicular.
C. The lines are parallel.

Answers

Answer:

A

Step-by-step explanation:

We can solve for y for both of the lines' equations to get the point-slope form.

L1: [tex]y=\frac{-2}{3} x+\frac{8}{3}[/tex]

L2:[tex]y=\frac{-3}{2}x+\frac{7}{2}[/tex]

So, the slopes of the two lines are [tex]\frac{-2}{3}[/tex] and [tex]\frac{-3}{2}[/tex].

Remember that parallel lines have the same slope, and perpendicular lines have opposite and reciprocal slopes. These slopes are reciprocal but not opposite.

Round 958.989730738 to the nearest hundred

Answers

Answer:

958.990

Step-by-step explanation:

958.990 is the Round off to the nearest hundred.

What is rounding a number to some specific place?

Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.

Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.

The digit 5 acts as a limit.

If the digit on right is 5, and after it there is only zeros or no value, then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)

WE have to Round 958.989730738 to the nearest hundred.

Hence, 958.990 is the Round off to the nearest hundred.

Working together, Candice and Ximena painted a fence in 8 hours. Last year, Ximena painted the fence by herself. The year before, Candice painted it by herself, but took 12 hours less than Ximena took. How long did Candice and Ximena take, when each was painting alone?

Answers

Answer: Time taken by Ximena to paint the fence alone  = 24 hours

Time taken by Candice to paint the fence alone = 12 hours

Step-by-step explanation:

Let x= Time taken by Ximena to paint the fence alone .

Time taken by Candice to paint the fence alone = x-12

As per given , we have

[tex]\dfrac{1}{x}+\dfrac{1}{x-12}=\dfrac{1}{8}\\\\\Rightarrow\ \dfrac{x-12+x}{x(x-12)}=\dfrac{1}{8}\\\\\Rightarrow\ 8(2x-12)=x^2-12x\\\\\Rightarrow\ 16x-96=x^2-12x\\\\\Rightarrow\ x^2-12x-16x+96=0\\\\\Rightarrow\ x^2-28x+96=0\\\\\Rightarrow\ x^2-4x-24x+96=0\\\\\Rightarrow\ x(x-4)-24(x-4)=0\\\\\Rightarrow\ (x-4)(x-24)=0\\\\\Rightarrow x=4, 24[/tex]

if x= 4

Time taken by Ximena = 4 hours

Time taken by Candice = 4-12 hours =-8 hours which is not possible. (time cannot be negative)

Therefore, x= 24

Such that

Time taken by Ximena to paint the fence alone  = 24 hours

Time taken by Candice to paint the fence alone = 24-12=12 hours

I am having trouble understanding this: Sam bought 86 pounds of flour for his bakery. Every day he used the same amount of flour to make bakery items. After 10 days, Sam was left with 25.2 pounds of flour. On average, how many pounds of flour did Sam use each day?

A. 3.01 Pounds
B. 5.65 Pounds
C. 6.08 Pounds
D. 11.12 Pounds

Please also include an explanation. Thanks!

Answers

Answer:

the average amount of flour used each day=6.08 pounds

Step-by-step explanation:

Sam bought 86 pounds of flour for his bakery.

Every day he used the same amount of flour to make bakery items.

After 10 days, Sam was left with 25.2 pounds of flour.

Now we are asked to find the average pounds of flour that Sam used each day.

Total amount of flour used=86-25.2=60.8 pounds.

As he used the flour equal amount each day for 10 days.

So, the average flour used each day=

amount of flour used/ number of days=60.8/10=6.08.

the average amount of flour used each day=6.08 pounds

Answer:

C

Step-by-step explanation:

So since Sam have 25.2 leftover pounds of flour, we can subtract that from 86, knowing that will be left over in the end. Next, we divide the number left. 86 - 25.2 = 60.8

Finally, divide that by 10, since there are 10 days.

We end up with 6.08 pounds.

A foreign country uses the stellar as its currency. Before a trip to that​ country, Mia wants to exchange ​$1700 to steller's. Which of Bank A and Bank B has the better exchange​ rate? How many more steller's would she get if she exchanged her ​$1700 at the better exchange rate instead of at the other​ rate?

Answers

Answer and explanation:

Stellar is a Brazilian cryptocurrency that is used to facilitate low cost and flexible payment. It was renamed lumens and is denoted XLM.

One stellar lumen is currently equal to $0.219096

For the purpose of the question and since it does not specify exchange rates for each bank, let's assume:

Bank A= 0.219097 to 1 US dollar

Bank B= 0.219099 to 1 US dollar

Using Bank A to exchange $1700 for stellars= $1700*0.219097= 372.464 stellars

Using Bank B to exchange $1700 for stellars= $1700*0.229042= 389.3714 stellars

From the above, we can see that Bank B has a better exchange rate as it is cheaper than Bank A(gives more stellar) . She should therefore use Bank B for her exchange.
