here ya go!!! I hope this helps <3
Answer:
<1 =33
<2 = 147
<4 = 147
Step-by-step explanation:
Angle 1 equals angle 3 because they are vertical angles. Vertical angles are opposite angles made by two intersecting lines.
<1 = <3
<1 = 33
Angle 2 and <3 are supplementary angles because they form a straight line. The add to 180 degrees
<2 + <3 = 180
<2 + 33 = 180
Subtract 33 from each side
<2 +33-33 = 180-33
<2 = 147
Angle 2 equals angle 4 because they are vertical angles
<2 = <4
<4 = 147
Exact form : 31/4
Decimal form: x=7.75
Mixed # form: x=7 3/4
The given equation is ,
→ y= 15 x+ 10, where y =total score on math quiz, and x= number of question answered
As this is the equation in two variables representing straight line.
As x> 0, ∴ number of questions attempted is always positive
So, as y, marks obtained will be also positive number.
By, taking positive integral values of x and y we can plot it's graph.
for example, if number of questions answered=2,4,6
then marks obtained=40, 70, 100
$200 x 12 = 2,400 (number of pencils they bought in 2006)
3/4 x 2,400 = 1,800 (number of pencils they used)
2,400 - 1,800 = 600 (number of pencils remaining)
1,800 - 600 = 1,200 (number of pencils needed)
They had to buy 1,200 more pencils in 2007.
