Azim wants to order school spirit t-shirts for the fundraising club. Company R charges a $70 screen setup fee plus $11.25 per t-shirt. Company S charges a $35 screen setup fee plus $14.75 per t-shirt. What equation can determine the number of t-shirts, x, that need to be ordered for the total cost of Company R to equal the total cost of Company S?

Answers

Answer:

10 t shirts

Step-by-step explanation:

70 + 11.25x = 35 + 14.75x

35 + 11.25x = 14.75x

35 = 3.5x

×/2=y/3; y/4=z/4 và x+2y-z=10

Answers

Answer:

Step-by-step explanation:

[tex]\dfrac{x}{2}=\dfrac{y}{3}\\\\[/tex]

Cross multiply,

3x = 2y    ------------(I)

[tex]\dfrac{y}{4}=\dfrac{z}{4}\\\\4*\dfrac{y}{4}=\dfrac{z}{4}*4\\\\y=z[/tex]

y = z --------------(II)

Plugin y =z in (I)

3x = 2z

3x/2 = z  ----------------(III)

x + 2y - z = 10

From (I) and (III)

[tex]x + 3x - \dfrac{3x}{2}=10\\\\4x - \dfrac{3x}{2}=10\\\\Multiply \ the \ entire \ equation \ by \ 2\\\\2*4x - 2*\dfrac{3x}{2}=10*2\\\\8x - 3x = 20\\\\5x = 20[/tex]

Divide both sides by 5

x = 20/5

x = 4

Plugin x = 4 in (I)

3*4=2y

12 = 2y

2y = 12

y = 12/2

y  = 6

z = y

z = 6

Answers

Answer:

you solve its better for yourself

Answer:

Angle A = 30 degrees

Step-by-step explanation:

Using the right triangle angle sum theorem(basically, if a triangle is right, the angle measurements have to be 90, 60, and 30 degrees), we can see that angle A can only be either 60 or 30 degrees.  Angle A is narrower than angle B, so we can infer that angle A = 30 degrees.

How much longer did Sarah practice than Eloise?

Answers

Answer:

21 min longer

Step-by-step explanation:

For Eloise, we need to know how much 1/5 of an hour is in min. So divide 60 by 5 and we get 12min. So 2/5 of an hour is 2x12, giving us 24 min.

For Sahrah, we need to know how much 1/4 of an hour is in min. So divide 60 by 4 and we get 15min. So 3/4 of an hour is 3x15, giving is 45 min.

now that we know how long they practiced, we find the difference by subtracting. 45-24 = 21
