Final answer:

By manipulating and then adding the given system of equations, we can eliminate the variable 'y', resulting in the equation 7x = 35.

Explanation:

To eliminate the variable y in the given system of equations, we need to manipulate the equations to cancel out the y term. The system of equations is:

x + y = 2

3x - 4y = 27

We can accomplish y-elimination by first multiplying the first equation by 4 to match the coefficient in front of y in the second equation. The equations now are:

4x + 4y = 8

3x - 4y = 27

Now, we can add the two equations together, effectively eliminating the y-variable:

4x + 3x = 8 + 27

7x = 35

Answer:

C

Step-by-step explanation:

x + y = 2

Subtract x from both sides;

y = -x + 2

3x - 4y = 27

Substitute y;

3x - 4(-x + 2) = 27

Distribute;

3x + 4x - 8 = 27

7x - 8 = 27

Add 8 to both sides;

7x = 35

Divide both sides by 7;

x = 5

In triangle ABC, the measure of angle B is 90 degrees, BC=16, and AC=20. triangle DEF is similar to triangle ABC, where vertices D, E, and F corresponds to vertices A, B, and C, respectively, and each side of triangle DEF is 1/3 the length of the corresponding side of triangle ABC. what is the value of sinF?(please show your work)

Answers

 The third side of triangle ABC is AB. Using the Pythagorean Theorem, its length is 12. 
12² + 16² = 20² 

∠F is congruent to ∠C and so the sin(∠F) = sin(∠C) 

The sin(∠C) = opposite/hypotenuse 
= |AB| / |AC| 
= 12/20 
= 3/5 
= 0.6 

So the answer is 0.6.

For two weeks, Mario recorded the color of the traffic light at the intersection of Main Street and North Avenue as his bus approached the intersection. He created this frequency table.

B. red, red, red, yellow, red, red, green, red, red, yellow
C.red, red, red, red, red, red, green, red, red, yellow
D.red, red, green, red, red, red, green, red, red, yellow

frequency table:
Red: 7
Green: 2
Yellow: 1
Total: 10

Answers

A. Because the data in the frequency table matches the data in A.
A because that's the only one with matching data.

The calculation of property tax is based on the A. homeowner's income.
B. sale price of the home.
C. amount of money borrowed for the mortgage.
D. assessed value of the home.

Answers

The answer is D. the assessed value of the home. In each jurisdiction that a home is at, there is a tax surveyor. This tax surveyor is in charge of finding the assessed values of all the homes in the area. Once this value is found, it is multiplied by another tax number called a mill levy. The resulting figure is the property taxed that is due on the home.

We already have 60\%60%60, percent of the items on our list, her father says. Anastasia sees 121212 items in the cart. How many grocery items are on the list?

Answers

If there were already 121212 items on the cart that only comprises of the 60 % of the list of the father, then there would be 202,020 items on his items in total. This is solve by dividing 121212 by 60% which will give us 202,020
