rewrite the equation in standard form y - 6 = -1/2 (x-5)

Answers

Standard Form: Ax + By = C

---A cannot be negative, nor can it be a decimal or fraction

y - 6 = -1/2(x - 5)

Distribute the -1/2

y - 6 = -1/2x + 5/2

Add -1/2x to both sides

1/2x + y - 6 = 5/2

Add 6 to both sides

1/2x + y = 17/2

Multiply everything by 2 to get rid of the fractions

x + 2y = 17

The number of seconds varies directly as the number of minutes. When 240 seconds have passed. 4 minutes have passed. If 420 seconds have passed , how many minutes have passed? ( help pls >.< )

Answers

Answer:

7 minutes.

Step-by-step explanation:

You can simply apply the well known rule if time: 60mins makes 1 hour,

or use proportion;

where x is the value you seek,

4=240

x=420

The relationship between 4 and 249 is 60 so,

420 divided by 60 equals 7 minutes.

There are 6 yellow, 4 orange, 2 green, and five blue plastic building blocks all the same
size in a bag. What is the probability of selecting an orange, putting it back, then
а
selecting a block that is not orange.

Answers

We want to get the probability of selecting an orange, putting it back, then selecting a block that is not orange.

We will see that the probability is P = 0.1799

In the bag we have:

6 yellow blocks4 orange blocks2 green blocks5 blue blocks.

For a total of 6 + 4 + 2 + 5 = 17 blocks.

First we want to find the probability of getting an orange block, as all the blocks have the same probability of being randomly drawn, the probability of randomly drawing an orange block is equal to the quotient between the number of orange blocks and the total number of blocks.

We get:

p = 4/17

Now we put the orange block back and we want to take a block that is not orange, the probability is computed in the same way:

q = (6 + 2 + 5)/17 = 13/17

The joint probability (this is, the probability of these two events happening together) is just the product of the individual probabilities.

We get:

P = p*q = (4/17)*(13/17) = 52/289 = 0.1799

Angela plays soccer and golf for a total of 125 minutes every day. She plays soccer 45 minutes more than she plays golf.

Part A: Write a pair of linear equations to show the relationship between the number of minutes Angela plays soccer (x) and the number of minutes she plays golf (y) every day. (5 points)

Part B: How much time does Angela spend playing golf every day? (3 points)

Part C: Is it possible for Angela to have spent 80 minutes playing soccer every day? Explain your reasoning. (2 points)

(10 points)

will give brainliest if u do all parts!!!

Answers

Part A

Answers:

x+y = 125

x = y+45

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

Explanation:

The first equation represents Angela playing both sports a combined 125 minutes. We simply add the variables x and y to represent adding the times for soccer (x) and golf (y).

Because she plays soccer 45 minutes more compared to golf, we also have the equation x = y+45.

==========================================================

Part B

Answer: 40 minutes

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

Explanation:

The second equation from part A says x = y+45

Because of this, we'll replace the 'x' in the first equation with y+45 and solve for y. I'm using the substitution rule.

So,

x+y = 125

y+45+y = 125 .... replace x with y+45

2y+45 = 125

2y = 125-45

2y = 80

y = 80/2

y = 40 minutes is the amount of time playing golf per day.

==========================================================

Part C

Answer: No it's not possible.

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

Explanation:

We found that y = 40 earlier. Let's used this to find x

x = y+45

x = 40+45

x = 85

Therefore, Angela spends 85 minutes playing soccer everyday. It's close to 80 minutes, but not quite there. So it's not possible that she spent 80 minutes playing soccer everyday.

Another way to show this is to say x+y = 80+40 = 120 which is five minutes short of the 125 minute goal.

Answers

Answer:

x° = 50° 2x°= 100°

Step-by-step explanation:

sum of all angle of triangle = 180° therefore

Step-by-step explanation:

Put it in an equation

x + 5 = x − 13

Let's solve your equation step-by-step.

x + 5 = x − 13

Step 1: Subtract x from both sides.

x + 5 − x = x − 13 − x

5 = − 13

Step 2: Subtract 5 from both sides.

5 − 5 = − 13 − 5

0 = − 18

y = 50, x = 74

Step-by-step explanation:

the total degrees must equal 180. In the left triangle, we are given 80 as in of them. 180-80=100 degrees left in the triangle there are two equal angles left, so we divide 100/2 and get 50, so y=50. In the triangle on the right, there are two equal angles of 53 degrees. So 53x2=106. 180-106= 74 degrees left. x is the only angle left, so x=72

Step-by-step explanation:

AS = AC + CS

6x -4 = (4x-1) + 7

6x - 4 = 4x + 6

6x - 4x = 6+ 4

2x = 10

x = 10/2

x = 5

AC = 4x -1 = 4(5) - 1 = 20 - 1 = 19

I hope I helped you^_^

Answer:

Step-by-step explanation:

AS = AC + CS

6x - 4 = 4x -1 +7

6x - 4 = 4x + 6

Add 4 to both sides,

6x = 4x + 6 + 4

6x = 4x + 10

Subtract 4x from both sides

6x- 4x = 10

2x = 10

Divide both sides by 2

x = 10/2

x = 5

AC= 4x - 1

= 4*5 - 1

= 20 - 1

= 19
