Emily earns $0.30 for every 0.75 mile she bikes. How much does she earn for 15 miles?

Answer: 9

Step-by-step explanation:

First solve the system (using elimination):

x-y=7...(1)

3x+2y=26...(2)

Multiply equation 1 by -3

 -3x+3y=-21

+ 3x+2y=26

 -----------------

     5y=5

      y=1

Substitute y=1 into equation 1

x-y=7

x-(1)=7

x=8

Let a=8 (x=a) and y=1 (y=b)

a + b

= (8) + (1)

= 9

Information provided with us :

What we have to calculate :

Performing Calculations :

Here we have been given with two equations,

From the first equation we would be getting a value of x and that value of x we would substitute in the second equation.

⇒ x - y = 7

⇒ x = 7 + y

Now, substituting it in the second equation :

⇒ 3x + 2y = 26

⇒ 3 (7 + y) + 2y = 26

⇒ 3 × (7 + y) + 2y = 26

⇒ 21 + 3y + 2y = 26

⇒ 21 + 5y = 26

⇒ 5y = 26 - 21

⇒ 5y = 5

⇒ y = 5 / 5

⇒ y = 1

★ Therefore, value of y is 1.

Now, substituting this value of y as 1 in the first equation.

⇒ x - y = 7

⇒ x - 1 = 7

⇒ x = 7 + 1

⇒ x = 8

★ Therefore, value of x is 8.

Value of a + b :-

⇒ x = a = 8

⇒ y = b = 1

Now,

⇒ a + b

⇒ 8 + 1

⇒ 9

Henceforth, value of a + b is 9.

Answer:

Points A and B are the same distance from the x-axis

Step-by-step explanation:

(x, y)    (x, y)

(3, -3)  (1, -3)

They have the same number for the y-axis. When the coordinates are on a graph, they are the same distance from the x-axis.

Point B is the closest to the y-axis.

Answer:

13A + 1

Step-by-step explanation:

Combine like terms. Like terms are terms that have the same amount of the same variable:

Set the expression:

12A + A + 2 - 1

(12A + A) + (2 - 1)

13A + 1

13A + 1 is your answer.

~

Hey there!

12a + 2 + a - 1

COMBINE the LIKE TERMS

= (12a + 1a) + (2 - 1)

= 12a + 1a + 2 - 1

= 13a + 1

Therefore, your answer is: 13a + 1

Good luck on your assignment & enjoy your day!

Answer:

d. 1 21/64 inches

Step-by-step explanation:

Add the lengths of the two punches.

4 1/64 + 4 3/32 = 4 1/64 + 4 6/64 = 8 7/64

Subtract the sum from the length of the bar stock.

9 7/16 - 8 7/64 = 9 28/64 - 8 7/64 = 1 21/64

Answer: d. 1 21/64 inches

The 1 15/64  inches of stock are wasted (option c).

To find out how much stock is wasted, we need to subtract the sum of the lengths of the two punches from the original length of the steel bar.

Original length of the steel bar = 9 7/16 inches

Length of the first punch = 4 1/64 inches = 4 + 1/64 inches

Length of the second punch = 4 3/32 inches = 4 + 3/32 inches

Total length of the two punches = (4 + 1/64) + (4 + 3/32) inches

Now, add the lengths of the two punches:

Total length of punches = 8 + 1/64 + 3/32 inches

Convert the fractions to a common denominator (64):

Total length of punches = 8 + 1/64 + 6/64 inches

Total length of punches = 8 + 7/64 inches

Now, subtract the total length of punches from the original length of the steel bar:

Wasted stock = 9 7/16 - (8 + 7/64) inches

Convert 9 7/16 to an improper fraction:

Original length of the steel bar = 9 * 16/16 + 7/16 = 151/16

Now, subtract the total length of punches:

Wasted stock = 151/16 - (8 * 16/16 + 7/64)

Wasted stock = 151/16 - (128/16 + 7/64)

Wasted stock = 151/16 - 130/16 - 7/64

Wasted stock = 21/16 - 7/64

Wasted stock = (21 * 4)/(16 * 4) - 7/64

Wasted stock = 84/64 - 7/64

Wasted stock = 77/64 inches

Now, let's simplify 77/64:

77/64 = 64/64 + 13/64 = 1 + 15/64 inches

To identify which triangles are congruent measure the angles and sides of each of the triangles and compare them.

In mathematics, the word congruent is used if two figures have the same size and shape, although their orientation can be different.

In the case of triangles two factors should be considered:

This means that to determine if the triangles are congruent, you must measure each side and angle and make sure these are the same in each triangle.

Answer:

Step-by-step explanation:

The first step is to figure out what the % is on the right.

The total is 100%

The left side is 60%

The right side is 100% - 60% = 40%

Now the 40% represents 28 students

The total number of students is 100%

40%/100% = 28/x            Cross multiply

40% x = 28 * 100%          Divide both sides by 40%

x = 28 * 100 / 40

x = 70

So the total number of students is 70

60% of them are on the left. 60/100 * 70 = 42

There are 42 students on the left.
