Answers

Answer 1
Answer: Given:
recipe: 2 tsp of butter
Melinda wants to make 40% more servings than the recipe.

2 tsp is equal to 100%
additional of 40% makes it 100% + 40% = 140%

140% * 2 tsp = 2.8 tsp.

The expression that shows the number of teaspoons needed is:
D. 1.4 x 2

Given AB || CD, what is the m

Answers

The value of x is 130° and that of y is 130° as AB and CD are parallel lines.

What is parallel lines?

Parallel lines in geometry are two lines in the same plane that are at equal distance from each other but never intersect. They can be both horizontal and vertical in orientation. Parallel lines can be found in everyday life, such as zebra crossings, notepad lines, and railway tracks. Two lines (in the same plane) are said to be parallel if they never collide, regardless matter how far they are extended on either side. Parallel lines travel parallel to each other, like train tracks.

Here,

x=180-50

x=130°

x=y

y=130°

Because AB and CD are parallel lines, the value of x is 130° and the value of y is 130°.

What is is 15% of 32.50 and how did u get your answer

Answers

15%=15/100=0.15
'of' means multiply
15% of 32.50=
0.15 times 32.50=4.875
or you can take 32.5 divide it by 100 and multiply it by 15. either way it is 4.875

Solve the system of equations2x+6y=-6, 4x-3y=-12
what is the solution to the system of equations

Answers

2x + 6y = -6   ...(1)

4x - 3y = -12  ...(2)

We can use the method of substitution or elimination to find the solution. I will use the method of substitution.

From equation (1), we can solve for x in terms of y:

2x = -6 - 6y

x = (-6 - 6y)/2

x = -3 - 3y

Now, substitute this value of x into equation (2):

4(-3 - 3y) - 3y = -12

-12 - 12y - 3y = -12

-15y = 0

y = 0

Substitute this value of y back into equation (1) to find x:

2x + 6(0) = -6

2x = -6

x = -3

Therefore, the solution to the system of equations is x = -3 and y = 0.

hope this helps

Answer:

x = -3, y = 0

Step-by-step explanation:

2x+6y=-6       equation1

4x-3y=-12      equation2

multiply equation2 by 2

2[ 4x-3y=-12]  

8x - 6y = -24      equation3

add equations 1 & 3

2x+6y=-6

8x - 6y = -24

--------------------

10x = -30

x = -3

substitute x = -3 to any of the equations

I will use equation1

2x+6y=-6

2(-3) + 6y = -6

-6 + 6y = -6

6y = 0

y = 0
