Provide the missing statements and reasons for the following proof.
Theorem opposite slides of parallelograms are congruent

Answer:

Step-by-step explanation:

Time needed to type 400 words is 13.3 minutes.

A unit rate means a rate for one of something.

Given that, you are taking a typing class and can now type 30 words per minute.

For 30 word, you need 1 minute.

Let you need x minutes for 400 words,

Therefore, the proportion will be,

1/30 = x/400

x = 400/30

x= 40/3

x = 13.33333 ≈ 13.3

Hence, you need 13.3 minutes to type 400 words.

Answer:

Yes, this equation is a system of equations because the two equations do intersect at the point, (0.323529411763, -1.23529411765), making them have a solution. *Work Below*

Step-by-step explanation:

Lets use the elimination method which is ...

4x-3y=5

2x+7y=-8

Multiply the bottom part by -2

(-2)2x+(-2)7y=(-2)-8

which equals...

-4x-14y=16

Rewrite the equations

4x-3y=5

-4x-14y=16

Add and the x's cancel making..

-17y=21

Divide by -17 to isolate y

y=-1.23529411765

Replace y with -1.23529411765 on one of the equations

4x-3(-1.23529411765) =5

x=0.323529411763

solution : (0.323529411763, -1.23529411765)

Answer:

(12, 1)

Step-by-step explanation:

Arbitrarily choose y = 1.  Then x - 6y = 6 becomes

x = 6(1) + 6, or x = 12.

Thus, one (of many) point on the graph is (12, 1).

Answer:

x=0, y=0

(0,0)

Step-by-step explanation:

First you see that y= -8x, so you would place that in the y variable for the question above, which means your question would now be 2x+4(-8x)=0. Now you would solve 4 time -8x which is -32x. The equation would then be 2x-32x=0. Then you would Combine Like Terms which would get you -30x=0. Then you divide -30 by 0 which gets you an x = 0. Then you would solve for y.   Lets make it easy. You can plug in the x to any of the substitution problems, but I prefer doing it to y= -8x since it is easier. You will see why. You would then do, -8(0) (0 is the x value) and your answer would be 0, because -8 times 0 is well 0. Once you got this, you know your x is 0 and y is 0, so your answer would be (0,0). The reason it is easier to substitute the bottom rather than the top is because for the top, you would do 2(0) + 4y = 0, then you would solve which gets you 0+4y=0, then subtract 0-0 which is 0, then you would divide 4y by 0 which gets you an answer of 0. This is much more complex than just substituting the problem for y = -8x. I really hope this helps you out. I know it is confusing, but if you keep on solving more of these and working them out, then it will become much easier for you.

the answer thats it 12,4

Answer:

  12.4 meters

Step-by-step explanation:

The area is the product of length and width. Fill in the given information in the formula and solve for length.

  A = LW

  198.4 = L×16

  198.4/16 = L = 12.4

The length of the patio is 12.4 meters.

Answer:

180, 145

Step-by-step explanation:

There are 60 minutes in an hour, so we do 3*60=180 for the first one.

For the second one, we first find the minutes in 2 hours, which is 2*60=120. We add 120+25 and get 45.

Step-by-step explanation:

1. 10x-7=5x+3; ⇒ 5x=10; ⇒ x=2. If x=2, then

2. QS=10*2-7=14;

3. SR=5*2+3=13;

4. m(∠PSR)=15*2+42=72°;

5. m(∠PSQ)=180-m∠(PSR)=180-72=108°.

Step-by-step explanation:

I am confused you basically solved your own question but here is the explanation.

Isaiah gets $12 per week in his allowance, every two weeks he gets $24, so in twenty weeks he would have save $240. Here is an equation.

2W*10 = $240

W = weeks

2 weeks = $24*10 = $240

Answer:

none

Step-by-step explanation:

Hello there, this is how we will solve your problem.\

here is the equation you gave us.

[tex]{\huge{\boxed{\mathbb{EQUATION}}}[/tex]

[tex]\begin{bmatrix}-5x+y=-3\\ 3x-8y=24\end{bmatrix}[/tex]

we can isolate [tex]x[/tex] and say [tex]x=\frac{-3-y}{5}[/tex]

Now here is our equation, [tex]\begin{bmatrix}3\left(-\frac{-3-y}{5}\right)-8y=24\end{bmatrix}[/tex] After we simplify it we get [tex]\begin{bmatrix}\frac{9-37y}{5}=24\end{bmatrix}[/tex], solve this and we get that [tex]y=-3[/tex], Before we said [tex]x[/tex] equals [tex]-\frac{-3-y}{5}[/tex], So now we can plug in our value that [tex]y[/tex] equaled, and now we have [tex]\frac{-3-(-3)}{5}[/tex]. Two negatives equal a positive and we get that [tex]x=0[/tex].

Answer:

1. 3/8 are female

2. 1/6 ton

3. 1 and 31/40 kg

Step-by-step explanation:

1. 5/8-male, 8/8 - 5/8 = 3/8

2. 2/15 + 3/15 = 5/15, 5/15 = 1/3, 1/3 = 10/30, (1/2 = 15/30) 15 - 10 = 5, 5/30 = 1/6

3. 7/8 + 9/10 = 71/40

Answer:

Step-by-step explanation:

1) 5/8 of the staff is male, 5/12 of the staff works part time

the question askes what fraction of the workforce is female

if 5/8ths is male than the other 3/8ths are female

3/8 of the staff is female

2) how much food was fed at night

2/15 + (2/15 + 1/15) + x = 1/2

2/15 + (3/15) + x = 1/2

5/15 + x = 1/2

1/3 + x = 1/2

x = 1/6

1/6th of a ton was fed at night

3)

just add them

7/8 + 9/10 = 71/40 or 1 31/40

Answer:

5,500 × 30%

Step-by-step explanation:

165.00 in intrest

If both Cody and Lisa play for t hours, then Cody pays a total of $(7 + t), while Lisa pays a total of $(1 + 3t). If they both pay the same amount P, then

7 + t = P

1 + 3t = P

Solve for t :

7 + t = 1 + 3t

t - 3t = 1 - 7

-2t = -6

t = 3

So Cody and Lisa each bowled for 3 hours, and they both ended up paying P = $10.

110<2x+10

Step 1: Flip the equation.

2x+10>110

Step 2: Subtract 10 from both sides.

2x+10−10>110−10

2x>100

Step 3: Divide both sides by 2.  

x>50

They used 4 buses and 4 cars

Step-by-step explanation:

136/30= 4.5 (which means we can full 4 buses)

If we fill 4 buses : 4x30=120

We have 4 vehicles left and 16 students left too.

4x4= 16

We can fit every studens in the cars.
