Answer:

y+2x=7 (1)

x=3+y (2)

Replace x = 3+y (2) into (1) => y+2(3+y) = 7

=> y = 1/3 and x = 3+1/3 =10/3

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation:

= y2-y1/x2-x1

3-2/1+2

1/3

Answer:

slope = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1,3) and (x₂, y₂ ) = (4, 4) ← 2 points on the line

m = [tex]\frac{4-3}{4-1}[/tex] = [tex]\frac{1}{3}[/tex]

Answer:

469.25

Step-by-step explanation:

peter=x

david=x+1.50

x+(x+1.50)=940

x=940-x-1.50

2x=940-1.50

2x=938.5

x=938.5/2

x=469.25

Answer:

the tringale has 3 lines of symmetry

Answer:

3/4

Step-by-step explanation:

you would get 6/8 but need to simplfiy to 3/4 since they both can divide by 2

Answer:

slope = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, - 2) and (x₂, y₂ ) = (4, 4) ← 2 points on the line

m = [tex]\frac{4-(-2)}{4-(-4)}[/tex] = [tex]\frac{4+2}{4+4}[/tex] = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]

Answer:

h=9.0991 ≈ 9.1

Step-by-step explanation:

V=π r²h

Answer:

c:7

Step-by-step explanation:

Answer:

7/10

Step-by-step explanation:

The ratio 10:7 represents the number of pink markers to the number of orange markers.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

Total number of pink Mrs. Andrews has = 10

Total number of orange Mrs. Andrews has = 7

The ratio of number of pink markers to the number of orange markers:

= 10:7

Thus, the ratio 10:7 represents the number of pink markers to the number of orange markers.

Answer:

B. 4

Step-by-step explanation:

Slope = (-2-6)/1-3) = = - 8/ - 2 = 4

Answer:

C.  4

Step-by-step explanation:

slope = (y2 - y1)/(x2 - x1)

slope = (-2 - 6)/(1 - 3)

slope = -8/(-2

slope = 4

Answer:

Let's define the variables:

x = yards of Organza ribbon that you buy.

y = yards of Satin ribbon that you buy.

We know that the price per yard of Organza ribbon is $0.07, this means tat if you buy x yards, the cost will be:

C = x*$0.07

And the cost of the Satin ribbon is $0.04, so if you buy y yards of that ribbon, the cost will be:

C = y*$0.04

Adding that together, the total cost is:

C = x*$0.07 + y*$0.04

Now we know that you pay $5, this means that the total cost is exactly $5, then we have the equation:

$5 = x*$0.07 + y*$0.04

Now we can isolate the variable y to get:

y = ($5/$0.04) - x*($0.07/$0.04)

y = 125 - x*1.75

Now we can just input different values of x to find the correspondent value of y.

This means that:

if x = 0 (0 yards of the Organza ribbon)

then:

y = 125 - 0*1.75 = 0

This combination is:

0 yards of organza, and 125 yards of satin.

Now, if x = 20, then:

y = 125 - 20*1.75  = 90

This combination is:

20 yards of organza, and 90 yards of satin.

if x = 40, then:

y = 125 - 40*1.75 = 55

This combination is:

40 yards of organza, and 55 yards of satin.

The 3 combinations that we found cost exactly $5.

Step-by-step explanation:

Answer:

56x + 34

Step-by-step explanation:

12(3 + 5x) + 1/4(16x - 8)

First, use the distributive property. You will get:

(12)(3) + (12)(5x) + (1/4)(16x) - (1/4)(8)

Next, multiply the numbers. You will then have:

36 + 60x + 4x - 2

Now, rearrange the numbers. The variables go in the front. This is what it should look like:

60x + 4x + 36 - 2

Add 60x and 4x, then subtract 36 and 2. This is your answer:

56x + 34

Answer:

28 would be the answer

Step-by-step explanation:

because 21+7= 28

Answer:

Only Integers are considered even or odd. So this is not possible to solve. But if you HAD to choose, I believe that it will be even because you round up then its 8 and there you have a even number
