Make "t" the subject of the formula s=2t+5.
Answers
Answer:
t = [tex]\frac{s-5}{2}[/tex]
Step-by-step explanation:
Given
s = 2t + 5 ( subtract 5 from both sides )
s - 5 = 2t ( divide both sides by 2 )
[tex]\frac{s-5}{2}[/tex] = t
Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.
Answers
Answer:
adult tickets 6.9
children tickets 3.9
Step-by-step explanation:
3x + y = 24.60 L1
5x + 4y = 50.10 L2
5L1 - 3L2
15x + 5y = 123
-15x - 12y = -150.3
-7y = -27,3
y = -27,3/-7
y = 3.9
3x + y = 24.60
3x + 3.9 = 24.60
3x = 24.60 - 3.9
3x = 20.7
x = 20.7 / 3
x = 6.9

Solve 5 (r +9) – 2 (1 - r) = 1.
The solution is r= ????
Answers
Step-by-step explanation:
5(r + 9) - 2(1 - r) = 1
5r + 45 - 2 + 2r = 1
7r + 43 = 1
7r = -42
r = -6.
Answer:
r = -6
Step-by-step explanation:
Given equation,
→ 5(r + 9) - 2(1 - r) = 1
Now the value of r will be,
→ 5(r + 9) - 2(1 - r) = 1
→ 5r + 45 - 2 + 2r = 1
→ 5r + 2r + 43 = 1
→ 7r = 1 - 43
→ 7r = -42
→ r = -42/7
→ [ r = -6 ]
Hence, the value of r is -6.

HELP Drag and drop the tiles with the coordinate points, so they match up with an equation that they satisfy (0,5) y = 13x + 5 y=-3x y = x - 10 (0,0) (8,-2) (-2,-21) (-5, -15) (-39)
Answers
Answer:
Step-by-step explanation:
1. y = 13x + 5
y = 13(0) + 5
y = 0 + 5
y = 5
(0,5)
y = 13(-2) + 5
y = -26 + 5
y = -21
(-2, -21)
2. y = -3x
y = -3(-3)
y = 9
y = -3(0)
y = 0
(0,0)
(-3,9)
3. y = x - 10
y = -5 - 10
y = -15
(-5, -15)
y = 8 - 10
y = -2
(8, -2)
The correct options are:
1. y = 13x + 5 ⇒ (0,5)
2. y = -3x ⇒ (0,0)
3. y = x - 10 ⇒ (8, -2)
