Yvonne used 5 tablespoons of butter for a recipe. For a second recipe she used 10% less butter than she did for the first recipe. The total amount of butter, in tablespoons, she used for both recipes can be found using the expression below:
5 + 5 – 5(10%)

Which other expression can be used to find the amount of butter, in tablespoons, she used for both recipes?

A. 10 – 5%
B. 10 – 50%
C. 5 + 5(0.9)
D. 5 + 5(1 – 10)

Answer:

No Solution

Step-by-step explanation:

Substituting y = -4x into the first equation, we get:

8x + 5(-4x) = 24(-4x)

Simplifying this equation, we get:

8x - 20x = -96x

Dividing both sides by -12x, we get:

-4/3 = -96

This equation has no solution, which means that the system of equations is inconsistent and does not have a unique solution.

Therefore, the system of equations cannot be solved to find the values of x and y.

Answer: B. Mantle

Step-by-step explanation:

I just couldn't pass up answering this question. I think the earth is very interesting.

The Earth's mantle is a thick layer of hot, flowing rock that lies beneath the crust. Convection currents within the mantle are responsible for the movement of the Earth's tectonic plates, which make up the continents and the ocean floor. As the mantle convects, it drags the plates along with it, causing them to move and interact with each other at their boundaries. This movement is responsible for many geological phenomena, including earthquakes, volcanoes, and the formation of mountain ranges.

Answer:

Simmons

Step-by-step explanation:

Simmons does 42 pushups in 360 seconds ,or 6 minutes. Magda does 24 pushups in 3 minutes. So by dividing by two you can find that Summons does 21 pushups in 3 minutes and 21<24

Answer: magda

Step-by-step explanation: a minute equals 60 seconds well to get to 360 you need five minute ( five sets of 60 )

Answer:

The value of Bettina's expression is 4 times greater than the value of Nikita's expression.

Step-by-step explanation:

expression = 72 + 26

Nikita is multiplying Bettina's expression by 4 [4x(72+26)]

Answer:

The second answer is correct.

Step-by-step explanation:

This is because its the same equation but just 4 times more.

Yes it is proportional because

3.5 x 3 = 10.5

4.2 x 2.5 = 10.5

Answer:

Yes, this is a proportional relationship

Step-by-step explanation:

When doing 3/2.5 = 1.2 and 4.2/3.5 = 1.2 so since both are the same answer itis equivalent

Answer:

A C and  D          

Step-by-step explanation:

Answer:The correct answer is A and C

Step-by-step explanation:

Answer:

step one combine like terms

step two through step 5 are are addition and subtraction property

step 6 division property

supplementary

[tex](3x + 25)^{0} + 2x^{0} = 180^{0}[/tex]

[tex]5x + 25 = 180[/tex]

[tex]5x = 180 - 25 \iff 5x = 155\\[/tex]

[tex]x = 155 : 5 \implies x = 31[/tex]

Answer: 8 months

Step-by-step explanation:

Answer:

x + y  and x - y are the simplest system of linear equations that has the ordered pair.

Example:

x + y = -2

x - y = 8

That's the answer to the ordered pair (3,-5)

Remember x = 3 and y = -5

Step-by-step explanation:

(-2, 2)

(-4, -2)

B

Answer:

B. 2

Step-by-step explanion

slope is caluclated by the change in y and change in x. so basiclly you would take one y value and subtract it from the other y value. -2-2=4.

then you would do the same with your x values. use the same coordinate that you got your y value from (i hope that made sense). -4-(-2)=-2.

after you find the change in y and change in x, you divide both those values. so we would do change in y divided by change in x. 4/2=2

so the slope equals 2. hope this helped!!

Answer:

25

Step-by-step explanation:

1) Find [tex]\frac{1}{6}[/tex] of 48

To find this we have to do 48 divided by then multiplied by one!

This means that the teacher graded 8 quizzes before school.

2) Add how many was graded after school

We know that the teacher also did 15 of how many quizzes were left over after school.

Previously he/she had done 8 so we have to subtract this by 48

15 more were done so we have to subtract this too...

25 are left!

Hope this helps, have a lovely day! :)

Answer:

25 quizzes

Step-by-step explanation:

48/6=8

8+15=23

48-23=25

Answer:

AC=3 in.

Step-by-step explanation:

It is given in the figure attached, in Δ ABC

∠ A = 90°

m∠B = 45°

AB = 3 in.

We have to find all sides of the triangle given

we will apply sine in Δ ABC to find the measure of AC

sinB =

Now by cross multiplication

BC = 3√2 in.

Now by Pythagoras theorem

BC²= AC² + AB²

(3√2)² = AC² + 3²

18 - 9 = AC²

AC = √9 = 3

Now we come to the options you have mentioned

AC = 3 in. is the correct answer.

Answer:

Surface area

Step-by-step explanation:

The surface area of a rectangular prism calculator gives us the answer: A = 2 × l × w + 2 × l × h + 2 × w × h = 2 × 8 ft × 6 ft + 2 × 8 ft × 5 ft + 2 × 6 ft × 5 ft = 236 ft²

Answer: 14:24  

Step-by-step explanation:

Answer:

1. 3 students

2. 1/10

Step-by-step explanation:

if there are 30 kids in the class, and 2/5 are in band that means 12 students are in band

30÷5 =6

6×2= 12

if 1/4 of those 12 play the saxophone, then 3 of those students play the saxophone.

12÷4= 3

3 is 1/10 of 30, which gives you the answer to the second question.

Answer: 280 shows.

Step-by-step explanation: The question stated that Circo the clown performs 5 shows a day, which means in a week (5x7 since there are 7 days in a week) he would perform 35 shows. Then you do 35x8, which will therefore give you your answer of 280 shows.

Answer:

Step-by-step explanation:

Solution

Distance between two points  =

(x 2−x 1) 2+(y 2 −y 1) 2

Given, one point =(2,−3)

Let, other point =(10,b)

absicca is x cordinate

(10−2) 2+(b+3) 2=108 2+(b 2+9+6b)=10

Squaring both sides, we get

64+b

2

+9+6b=100

(b+3)

2

=36

∴ b+3=6 and b+3=−6    

∴ b=3 and b=−9

Answer:

C

Step-by-step explanation:

There is 8 on one side and 2a + 2 on the other so we can eliminate answer D.
8=2a+2

We take away 2 from both sides getting a on one side. So 6=2a. To find a we do the inverse way to solve the equation. To get 6 we multiply "a" by 2. To get "a" we dp 6/2 = 3. boom a=3 so C is your answer

Answer:

3 seconds

Step-by-step explanation:

1 minute = 60 sec

fill rate = 20 pints/60 sec = 0.33 pints/sec      

t = time

(0.33 pints/sec)(t) = 1 pint    

t = (1 pint) / (0.33 pint/sec) = 3 sec
