Answer:
1). 24
2). 8
Explanation:
1).
285$ - 45$ = 240$
240$/10 = 24$
Therefore, he pays 24$ a month.
2).
Let x be the number than triple:
3x - 5 = 19
3x = 19 + 5
3x = 24
x = 24/3
x = 8
Step-by-step explanation:
The scientific notation:

<em>1 ≤ a < 10</em> and <em>k -</em><em> any integer number</em>

Answer:
0
Step-by-step explanation:
To calculate the slope or gradient we use this formula:
Slope = y2-y1/x2-x1
(-3,2) = (x1, y1)
(4,2) = (x2, y2)
Slope = 2-2/4-(-3) = 0

Answer:
m∠Q = 121°
m∠R = 58°
m∠S = 123°
m∠T = 58°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Create an expression for the sum of all the angles and equate it to 360, then solve for x:
∠Q + ∠T + ∠S + ∠R = 360
⇒ 2x + 5 + x + 2x + 7 + x = 360
⇒ 6x + 12 = 360
⇒ 6x = 360 - 12 = 348
⇒ x = 348 ÷ 6 = 58
So now we know that x = 58, we can calculate all the angles:
m∠Q = 2x + 5 = (2 x 58) + 5 = 121°
m∠R = x = 58°
m∠S = 2x + 7 = (2 x 58) + 7 = 123°
m∠T = x = 58°
