Which choice shows the corresponding size as equal?

Answer:

C. 3n(6) + (6 – 2)

Step-by-step explanation:

C. 3n(6) + (6 – 2) has a coefficients, a product and a sum

Coefficients = 3

3 is the coefficients of n

Product means multiplication

3n(6) = product of 3n and 6

Sum means addition(+)

3n(6) + (6 – 2) = the addition of 3n(6) and (6 - 2)

3n(6) + (6 – 2)

= 18n + (4)

= 18n + 4

Answer:

Step-by-step explanation:

1. The expression for c in the first equation is (30m+50). Substituting that for c in the equation ...

  c = 20m +100

gives you ...

  30m +50 = 20m +100

__

2. Adding -50-20m to both sides gives ...

  10m = 50

  m = 5 . . . . . . . divide by 10

__

3. Doing the substitution in reverse, you would substitute (20m+100) for c in the equation ...

  c = 30m +50

to get ...

  20m +100 = 30m +50

This is the equation of part 1 with the expressions swapped to the other side of the equal sign. The symmetric property of equality tells you that changing sides of the equal sign does not change the value of the variable(s).

You get the same solution.

Step-by-step explanation:

For question 1 is a 50% chance on going on either heads or tails

for question 2 it will be green there is less of the blue buttons and more green

Answer:

Step-by-step explanation:

Ok so for question one we use the Pythagorean theorem, which is a^2+b^2=c^2

a is the shortest leg, b is the leg that is not the hypotenuse. and c is the hypotenuse which is the opposite leg to the right angle.

Question 1: a=9,b=12,c=x

(9)^2+(12)^2=(x)^2

81+144=(x)^2

225=(x)^2

x=15

Question 2: a=10,b=24,c=x

(10)^2+(24)^2=(x)^2

100+576=(x)^2

676=(x)^2

x=26

Question 3: a=3,b=7,c=x

(3)^2+(7)^2=(x)^2

9+49=(x)^2

58=(x)^2

x=root58, or 7.615773

Question 4: a=6,b=x, c=10

(6)^2+(x)^2=(10)^2

36+(x)^2=100

Subtract 36 from both sides

(x)^2=64

x=8

Question 5: a=6,b=x, c=24

(6)^2+(x)^2=(24)^2

36+(x)^2=576

Subtract 36 from both sides

(x)^2=540

x=6root15, or 23.2379

Question 6: a=1, b=1, c=x

(1)^2+(1)^2=(x)^2

1+1=(x)^2

2=(x)^2

x=root2, or 1.414213562

Question 7: a=8, b=x, c=21

(8)^2+(x)^2=(21)^2

64+(x)^2=441

Subtract 64 from both sides

(x)^2=377

x=root377, or 19.41648784

Question 8: a=24, b=x, c=30

(24)^2+(x)^2=(30)^2

576+(x)^2=900

Subtract 576 from both sides

(x)^2=324

x=18

Question 9: a=5,b=9, c=x

(5)^2+(9)^2=(x)^2

25+81=(x)^2

106=(x)^2

x=root106, or 10.29563014

Question 9 Part B: a=3, b=5, c=y

(3)^2+(5)^2=(y)^2

9+25=(y)^2

34=(y)^2

root34, or 5.830951895=y

Hence, second option is the true option.                            {Result of spin, card color}

{Green, Purple} {Yellow, Purple}  {Purple, Purple }

{Green, Green}  {Yellow, Green}  {Purple, Green}

Step-by-step explanation:

It is given that:

A spinner with 3 equal sectors is shown in the figure. The colors Green, Yellow, and Purple are marked on it.

Two cards are shown on the right side. Their colors are Purple and Green.

The table that identifies the sample space of spinning the spinner and then selecting  a card is:

     {Result of spin, card color}

{Green, Purple} {Yellow, Purple}  {Purple, Purple }

{Green, Green}  {Yellow, Green}  {Purple, Green}

( Since in rest of the options the red color in the sample space but there is no card or no such color in the spin which is red)

Each color on the wheel can match with each color of the cards:

Wheel has green, blue red

Cards are purple and green:

The combinations could be:

Green purple , green green, blue purple, blue green, red purple, red green

3x² - 2x² + y² + 2x - 3y + 2y + 4xy - 4xy

x² + y² + 2x - y

Answer:

5

Step-by-step explanation:

this can be solved using simultaneous equation

2a + 3b = 19  equation 1

1a + 4b = 17    equation 2

Multiply equation 2 by 2

2a + 8b = 34  equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

Answer:

Step-by-step explanation:

2a + 3b = 19 equation 1

1a + 4b = 17 equation 2

Multiply equation 2 by 2

2a + 8b = 34 equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

Step-by-step explanation:

Answer:

42

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary. We use that information and angles B and D to find the value of x. Then we use the value of x to find the measure of angle A.

m<B + m<D = 180

2x + 3x - 5 = 180

5x = 185

x = 37

m<A = x + 5

m<A = 37 + 5

m<A = 42

18.5= X

7×18.5= 129.5

129.5+159.12= 288.62

Answer:

figure it out

Step-by-step explanation:

Answer:

37

Step-by-step explanation:

x = 1st number

y = 2st number

z = 3rd number

x + y + z = 235

y = x + 15

z = 8x

x + x + 15 + 8x = 235

10x = 220

x = 22

y = 37

z = 176

The second number is 37.

Given that,

Based on the above information, the calculation is as follows:

x + y + z = 235  

y = x + 15  

z = 8x

Now  

x + x + 15 + 8x = 235

10x = 220

x = 22

So,

y = 22 + 15

= 37

StartFraction 1 Over 16 EndFraction of a pound

Step-by-step explanation:

Total pounds of sunflower seeds Jordan bought = 9/16 of a pound

Number of snack bags for his lunch = 9

What is the weight of sunflower seeds in each snack bag?

Weight of sunflower seeds in each snack bag = Total pounds of sunflower seeds Jordan bought / Number of snack bags for his lunch

= 9/16 ÷ 9

= 9/16 × 1/9

= (9*1) / (16*9)

= 9 / 144

= 1/16

Weight of sunflower seeds in each snack bag = 1/16 of a pound

Answer:

B

Step-by-step explanation:

So wiggly, remember that slope is change in y/change in x, or in simpler terms, y/x. Thinking of this, y/x must simplyfy to -3. Or, you can think of it as -3/1.

So know that we have rewrote this as a slope of -3/1, lets use it. Where do we start? Well, we must start at point A, which is at 2 x and 7 y.

Now, going to the  RIGHT(+1x) and going DOWN(-3y) we will go from 2x and 7y to 3x and 4y.

Are we on a point yet? Nope, lets do this again.

Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 13x and 4y to 4x and 1y.

Are we on a point yet? Still no, lets try this one more time.

Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 4x and 1y to 5x and -2y.

Are we on a point? YUP. We cna see that point B is at 5x and -2y.

Hope you get it right ;)

The division is one of the four fundamental arithmetic operations. The unit rate in meters per year is 0.10417.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given A tree in Aldo's backyard has been growing for 2 2/5 years. Also, the tree is 1/4 meters tall. Therefore,  the unit rate in meters per year can be written as,

[tex]{\rm Unit\ rate} = \dfrac{\frac14}{2\frac25} = \dfrac{1}{4} \times \dfrac{5}{12} = 0.10417[/tex]
