Step-by-step explanation:
When deciding where to put an ordered pair on a graph its important to understand how ordered pairs work.
An ordered pair is split up into to pieces
(x,y) or number example (3,5)
When graphing the x coordinate will fall on your horizontal line or the line that looks like the horizon.
When graphing the y coordinate it will fall on your vertical line or the line that goes right up into the sky like a rocket.
To graph (3,5)
Go to the right 3 and up 5
Sometimes helps to use both fingers to keep your spot. Slide both fingers until they collide and that's where you would plot your point!
Hope this helps if you have an questions just comment and ill try to explain further.
Answer:12.1
Step-by-step explanation:
Angle D=180-(82+52)
Angle D=180-134
Angle D=46
Using sine rule
e/sinE=d/sinD
e/sin52=11/sin46
e/0.7880=11/0.7193
e/0.7880=15.29
Cross multiply
e=15.29 x 0.7880
e=12.05
e=12.1 approximately
The main idea here is to "translate" the words into maths.
First we need to identify the unknowns and label these.
We need to know the number if dimes and the number of quarters. So lets say
x: number of dimes
y: number of quarters
Now lets write equations from the written problem.
We know that there are 36 coind total, thus:
x + y = 36
We also know that the coins total 5.85 dollars, but it is better to count in cents, that is 585 cents.
x are the number of dimes, their value is x*10
y are quarters with value of y*25
thus:
10x+25y=585
We have two equations and two unknowns now, that needs to be solved to get the answer.
x + y = 36
10x+25y=585
