The difference between two numbers is 40. Twice the first number plus three times the second number
is 100. Find the numbers. Provide a full solution.

Answers

Answer:

x = 44 and y = 4

Step-by-step explanation:

Given:

x - y = 40

2x + 3y = 100

Isolate for x in the first equation:

x = 40 + y

Sub x = 40 + y into the second equation and solve for y:

2(40 + y) + 3y = 100

80 + 2y + 3y = 100

5y = 20

y = 4

Sub y = 4 into the equation for x:

x = 40 + 4

x = 44

Therefore, x = 44 and y = 4

Answers

Answer:

47.43

Step-by-step explanation:

Please consider brainliest. Bye!

Answer:

Your answer is 47.43 or 46.54.

Step-by-step explanation:

First we will add the prices up it equals 63.75$.

The sale of 20% = 63.75 x 20% = 12.75

63.75 - 12.75 = 51

Now we calculate the tax

51 x 7% = 3.57

51 - 3.57 = 47.43

The total is 47.43.

Or you could at the percentages up and subtract.

63.75 - 27% = 17.21.

63.75 - 17.21 = 46.54

what is the answer? help please

Answers

Answer:

the answer for the fifth side would be 9 inches.

Step-by-step explanation:

if you know that two sides are 5 inches long and the other two sides are 4 inches long then add 5+5+4+4 which equals 18 so then subtract 27 from 18 and you get 9 which is the length of the last side. 9 inches. I hope this helps

Answer:

9 in

Step-by-step explanation:

The sum of the five sides = 27 in

We know that 2 sides are 5 in and 2 sides are 4 in

Let x be the length of the fifth (unknown) side

Therefore, 5 + 5 + 4 + 4 + x = 27

Combine like terms:  18 + x = 27

Subtract 18 from both sides:  x = 9

Therefore, the fifth (unknown) side is 9 in long

Given that PQRS≅WXYZ, find the corresponding parts.

Answers

Answer:

wz is the corresponding part

Step-by-step explanation:

The corresponding parts between PQRS and WXYZ are, PQ corresponds to WX, QR corresponds to XY, RS corresponds to YZ, SP correspond, ds to ZW.

If PQRS is congruent (≅) to WXYZ, it means that the two figures are identical in shape and size. Each letter represents a corresponding part between the two congruent figures.

To find the corresponding parts, we can match the corresponding vertices of the polygons. Let's match the vertices of the polygons:

P corresponds to W.

Q corresponds to X.

R corresponds to Y.

S corresponds to Z.

Therefore, the corresponding parts between PQRS and WXYZ are:

PQ corresponds to WX.

QR corresponds to XY.

RS corresponds to YZ.

SP corresponds to ZW.

6(2x – 4) = 10 – 8x Identify the number of solutions for each equation (one, none, or infinitely many)​

Answers

Answer:

one solution: x = 1.7

Step-by-step explanation:

6(2x - 4) = 10 - 8x

Multiply brackets:  12x - 24 = 10 - 8x

Add 8x from both sides:  20x - 24 = 10

Add 24 to both sides:   20x = 34

Divide both sides by 20:  x = 1.7

Therefore, one solution:  x = 1.7

Set B is the set of positive two-digit odd numbers greater than 49 that are divisible by 5.

Answers

Answer:

B = {55, 65, 75, 85, 95}

Step-by-step explanation:

A set is a list or group of numbers. We use these { } squiggly brackets to contain the list of numbers. Two-digit numbers are 10 to 99. But they said we're starting from 49. So our list will have only numbers between 49 and 99. BUT, they also said divisible by 5. Numbers divisible by five end with a 0 or 5...so, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95...BUT: they also said ODD numbers. So we only keep the numbers ending in 5.

Finally, we end up with B = {55, 65, 75, 85, 95}

The set B is  { 55, 60, 65, 70, 75, 80, 85, 90, 95}

What are sets?

A set is a collection of elements or numbers or objects, represented within the curly brackets { }.

For example: {1,2,3,4} is a set of numbers.

Given statement:

Set B is the set of positive two-digit odd numbers greater than 49 that are divisible by 5.

So, the two digit number that greater than 49 and divisible by 5 are

55, 60, 65, 70, 75, 80, 85, 90, 95.

Hence, set B= { 55, 60, 65, 70, 75, 80, 85, 90, 95}
