Which are the vertically opposite angles?

Which are the supplementary angles?

Which are the adjacent angles?

Answer:

y= 7 and -1

Step-by-step explanation:

Answer:

y= 2x

Step-by-step explanation:

Find the slope of the original line and use the point slope fromula y-y1=m(x-x1) to find the line parallel to 2x-y=-1

Original

y=mx+b

y=2x +1

Answer:78.4

Step-by-step explanation:

(74+44+74+100+98+86+72+76+66+94)/10 = 78.4

Answer:

The bicyclist rides 72 miles in 4 hours

Step-by-step explanation:

Answer:

if you know this or not but 5  points is not 50

Step-by-step explanation:

Answer:

$34.5

Step-by-step explanation:

Turning the 3/4 into a decimal would be .75, .75 can go into 7.5 10 times. You would multiply 10 by the cost $3.45 and you would get $34.5 for 7.5 lbs of walnuts.

Answer:

y=-17 x=10

Step-by-step explanation:

4x-3y=11

8x+2y=46

8x-6y-22                                                      8x+2(-17)=46

8x+2y=46                                                     8x-34=46

2y-6y        46-(-22)                                            8x=80

-4y=68

y=-17  x=10

Answer:

3([tex]\frac{1}{3}[/tex]x+8)=11

Step-by-step explanation:

It says 3 times the sum of one third of a number and 8, so we group that expression into the parentheses. Since there is a key word is, we need to put an equal sign.

Answer:

Answer:

Amount borrowed from friend = 4000

From Bank = 8000

From insurance = 3200

Step-by-step explanation:

Given that:

Amount borrowed = $15200

Let amount borrowed from friend = x

x at 5% = 0.05x

From Bank = 2x at 8% = 0.08*2x = 0.16x

From insurance = 15200 - (x + 2x) at 4%

From insurance = 15200 - 3x at 4% ; (15200 - 3x)* 0.04 = 608 - 0.12x

Interest paid in first year = $968

Simple interest = principal * rate * time

968 =

968 = (0.05x + 0.16x + 608 - 0.12x)

968 - 608 = 0.05x + 0.16x - 0.12x

360 = 0.09x

x = 360 / 0.09

x = 4000

Hence,

Amount borrowed from friend = 4000

From Bank = 2x = 4000 * 2 = 8000

From insurance = 15200 - (4000 + 8000) = 3200

Answer:

[tex]12[/tex] is the answer

Step-by-step explanation:

Given

[tex]x = 5[/tex]

Required

Evaluate

[tex]3(x + 4) + 2x - x^2[/tex]

To answer this question, we simply substitute 5 for x in [tex]3(x + 4) + 2x - x^2[/tex]

[tex]3(x + 4) + 2x - x^2[/tex] becomes

[tex]3(5 + 4) + 2*5 - 5^2[/tex]

[tex]3(9) + 10 - 25[/tex]

Open all brackets

[tex]3*9 + 10 - 25[/tex]

[tex]27 + 10 - 25[/tex]

[tex]12[/tex]

Step-by-step explanation:

2c+10=30

2c+10−10=30−10

2c=20

2c÷2=20÷2

Answer: c=10

Answer:

10

Step-by-step explanation:

2c + 10 = 30

so we take 10 to the other side to become - 10.

Therefore 2c = 30 - 10

= 20

Divide both sides by the coefficient of c that's 2

2c = 20

c = 10

Answer:

what language is that ??

Step-by-step explanation:

Answer: D. The percent is greater than 0 and less than 100, and the decimal is between 0 and 1.

Answer:

c+2

Step-by-step explanation:

Im not 100% sure I understand what you mean by this but anytime it says and in a statement it means + so c+2 would be the answer.

Answer:

x = 3 in

Step-by-step explanation:

Since it's a square, to find the area, all you have to do is multiply one side of the square by another. Since this is a square, all the sides are equal. so 3x3 = 9. 9 sq. in.

Answer:

106.33

Step-by-step explanation:

after decimal you have .3 tenths 2 hundredths 7 thousandths

to round to the nearest hundredths look at thousandths 7 becasuse is greater then 5 then you round up

106.327 is rounded to 106.33

Answer:

your answer is 106.3

Step-by-step explanation: so first you do this

[tex]106.327\\3 =tenths\\2= hundredths[/tex]

so when you round  if it is 5 or above you round up if it is 4 or below leave it alone

so the final answer is 106.3

when you round the 27 is removed and this is what you have left.

its either C or D :)

Answer:

richard is 22 and teo is 9

Step-by-step explanation:

Step-by-step explanation:

The given number is 3.5×10⁶. It is written in scientific form. We can first write it into standard form. There is exponent of 10 is 6.

3.5×10⁶ = 3.5×1000000

We can write 3.5 as 35/10

So,

3.5×10⁶ = (35/10)×1000000

= 3500000

One of the zero of 1000000 is divided by 10 at the denominator. Hence, the exponent in 3.5×10⁶ is 6 while there are 5 zeros in 3500000.

Answer:

Porportional

Step-by-step explanation:

-1 x = -15 y

-7 x -15 = -105, correct

-9 x -15 = -135, correct

Because all are correct, this is porportional. This means that there is a unit rate and if this were graphed, the line would be straight.

I Hope That This Helps! :)

Answer:

I would say 14 weeks.

Step-by-step explanation:

I solved it by subtracting what she already has from the price of the bike. $164-52= 112. Then I divided that by 8 cause she saving $8 a week and you get 14. So in 14 weeks she'll have enough money to buy the bike.
