Solve the system of linear equations by elimination.

x+4y=1
3x+5y=10

Answers

Answer 1

Answer:

x = 5 , y = -1

Step-by-step explanation:

Solve the following system:

{4 y + x = 1 | (equation 1)

5 y + 3 x = 10 | (equation 2)

Swap equation 1 with equation 2:

{3 x + 5 y = 10 | (equation 1)

x + 4 y = 1 | (equation 2)

Subtract 1/3 × (equation 1) from equation 2:

{3 x + 5 y = 10 | (equation 1)

0 x+(7 y)/3 = -7/3 | (equation 2)

Multiply equation 2 by 3/7:

{3 x + 5 y = 10 | (equation 1)

0 x+y = -1 | (equation 2)

Subtract 5 × (equation 2) from equation 1:

{3 x+0 y = 15 | (equation 1)

0 x+y = -1 | (equation 2)

Divide equation 1 by 3:

{x+0 y = 5 | (equation 1)

0 x+y = -1 | (equation 2)

Collect results:

Answer: {x = 5 , y = -1

Answers

Answer:  0.40

Reason:

6 black out of 4+6+5 = 15 total

6/15 = 0.40 is the experimental probability of selecting black.

Side note: The term "empirical probability" is the same as "experimental probability".

The experimental probability of selecting a black marble will be 0.40. The correct option is C.

What is probability?

Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.

Probability = Number of favourable outcomes / Number of samples

Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.

Number of favourable outcomes = 6

Number of samples = 4+6+5 = 15

Probability = Number of favourable outcomes / Number of samples

Probability = 6 / 15

Probability = 0.40

Therefore, the probability will be 0.40.

How can I find the cube root of 64?

Answers

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Could any one say for me the volume and the surface for "Pyramid, Cone and Sphere"
Plz help!!
Who will answer will be the *"Brainliest"*

Thank u

Answers

Answer:

Pyramid: In fact, the volume of any pyramid is one-third the area of the base times the height. Finding the surface area of a pyramid is done by first finding the area of the base and the area of each lateral face. … Lastly, the surface area of a pyramid is the sum of the area of the base and the lateral area!

Cone: a volume of 4 3 π r 3 \frac{4}{3} \pi r^3 34πr3 and a surface area of 4 π r 2 4 \pi r^2 4πr2.

Sphere: A cone is essentially a pyramid with a circular base. The volume of a pyramid is given by Vpyramid=Abase⋅h3. Since the area of the base of a cone is πr2, the formula for the volume of a cone is Vcone=πr2h3.

15) x=29 ; (2x+1) = 59° ; (x+2) = 31°

16) x=17 ; (4+2x) = 38° ; (3x+1) = 52°

Step-by-step explanation:

So for each problem you follow the same steps.

1) See what the angles should measure up to. (#12 is 180°, and #15 & 16 is      90°

2) Write your equation. (I'm going to use #12 as an example). 4+5x+x+2=180

3) Simplify the equation. 6x+6=180

4) Solve the equation. x=29

5) Then replace each x with the 29, and solve.

6) To double-check the angles, add both angles together and they should be 180° (or whatever you decided you were solving for on step 1)

Skew

A skew segment is one that does not and cannot lie in the same plane as a given line segment. Here, segments AD, BC, EF are all parallel to segment GH, so could lie in the same plane with GH.

Segments AH and DG intersect GH, so also could lie in the same plane with GH.

Can I have brainlist pls?

if everyone only needs one parking space altogether, the equation would be 160=15.50x+5

to solve that, you would need to move the 5 to the left and then divide the equation by 15.50

so it would look like this: (155=15.50x)/15.50

155/15.50 equals 10, so your answer would be x=10
