Answer 1

Answer:

300 + r = 217

Step-by-step explanation:

300 -> 300

added to r -> +

is the same as -> =

217 -> 217

Put this in one equation and you get:

300 + r = 217

If you need to solve for r (need to isolate r to solve for r):

300 + r = 217

r = 217 / (-300)

r = -0.723333333

Answer 2

You are right 300+r=217

Hello there!

Linear functions have a continuous pattern in their x and y values.

Let's see the first table.

0, 1, 2, 3

We add 1 every time.

-3, -2, 0, 3

We add 1, add 2, add 3.

That's not a linear function, because it doesn't have a continuous pattern in its y values.

Let's look at the next table.

0, 1, 2, 3

We add 1 every time.

1, 4, 3, 7

We add 3, subtract 1, add 3

That's not a linear function as well.

Now, let's look at the third table:

0, 1, 2, 3

We still add 1.

2, 0, -2, -4

We subtract 2 every time.

So this is a linear function. Hope this helps!

Answers

Answer:

-10.6 or 53/5

Step-by-step explanation:

go ogle math

Answer: (3) 73/230

Step-by-step explanation:

You times whats in the brackets with 23 then remove the brackets which makes it = -71.3 - 23x = 5

Then i would swap the 23x and 5 around which makes it = 71.3 - 5 = 23x

subtract 71.3 - 5

-76.3 = 23x

Divide -76.3 by 23 (Use a calculator) =

(3) 73/230

Thats how simplified it can go. (fraction cant be simplified more)

(3) is the leftover whole number that is next to the mixed number

help me please i need to find out what the sum is and what the product is and the remaining qotient

Answers

Answer:

Quotient 5/6

Product 8b

Sum 5/6+8b

Step-by-step explanation:

Sum is addition and there is only one expression of the three that has addition. So sum goes with 5/6+8b.

Quotient is division or fraction so 5/6 is the expression to go with quotient.

Product is times so 8b is the expression that goes with that because 8b means 8 times b.

Answer:

Quotient 5/6

Product 8b

Sum 5/6+8b

What additional information is required to prove the triangles are congruent using ASA?
Since vertical angles are congruent assume:

Answers

Answer:

Step-by-step explanation:

We already have one angle form the question that leaves us with one other angle and one side that we need to find, since we are required to use ASA or angle-side-angle.

the diagram gives us 2 congruent sides UB and AB since they have a similar slash on both of them, finally we need one more angle, so we look at the choices we have:

a) it gives us congruent sides not angles, so we move to the next

b) same thing as A

c) gives us 2 congruent angles, and since these are 2 new angles not given in the question, they can work

d) these 2 angels are the same 2 given in the question, so we can't use them.

Will give 20 points to whoever can answer all of the questions.

Solve for x.
4 (x + 1 1/3) = 9 2/3
Enter your answer as a mixed number in simplest form.

Answers

Answer:

x = 13/12

x = 1 1/12

Step-by-step:

4 (x + 1 1/3) = 9 2/3

4x + 5 1/3 = 9 2/3

subtract 5 1/3 from each side

4x = 4 1/3

divided by 4 on each side

x = 13/12

x = 1 1/2

X = 1 1/4

Drag each angle measure to the correct location on the image. Each angle measure can be used more than once.

In the figure, two parallel lines are cut by two other parallel lines. The measures of one of the angles is labeled. Find the measures of the other angles and label them.

137° 52° 128° 38°

*then it’s the picture*

Answers

Answer:

In front of the 52, it'll be 52°, that's all I know.

Vertical angles are always congruent. Since the lines are parallel, we can use the Alternate Interior Angle Theorem.

The way I got 128 was by using the fact that the angles would add up to 360 and the Vertical Angle Congruence Theorem. Basically, the formula is x + x + y + y = 360°. If you replace x with 52°, we can deduce that y is equal to 360 - (52 + 52)/2. That gives us 128°.

For this linear equation, give the number by which you would multiply the terms in each equation in order to eliminate one of the variables. Then solve this system:

The solution to this system of linear equations 3x – 2y = 14 and 5x + y = 32 is (x, y) is (6, 2).

Answer:

Step-by-step explanation:

If we choose to eliminate x, multiply the first equation by -3: -15x - 6y = 3

and multiply the second by 5: -15x - 35y = 55

Note that this allows us to eliminate x. We get:

-6y = 3

-35y = 55

which sum up to -41y = 58. Thus, y = -58/4.
