Once we find what x and y is, that's where they intercept and we can write that as an ordered pair as (x,y)
Now we need to find what y is. So let's put x into the original first equation
3x+4y=16
3(4)+4y=16
12+4y=16 ---Subtract 12 from both sides
4y=4 ---Divide both sides by 4
y=1
Alright, so our ordered pair is (4,1)
Answer:
42.5 Cubic Yards
Step-by-step explanation:
To find volume of a rectangle you do length*width*height to get the volume, so 17*15*0.5(because 6 inches is half of a foot) you get 127.5, but they're asking for it in yards not feet so you need to divide 127.5 by 3 and that will give you 42.5.
Answer: The jet will fly 4400miles in 8 hours.
Step-by-step explanation:
Let the missing value be represented by x
2 hours = 1100 miles
8 hours = x
We cross multiply:
2x = 1100 x 8
2x = 8800
Divide both sides by 2 to get the value of x
x = 8800/2
x = 4400
Therefore, the jet will fly 4400miles in 8 hours.
Answer:
x=58
Step-by-step explanation:
1) You have to remember all triangles have to equal 180 degrees
2) You have to know that the box on the left-hand corner of the triangle means it's angle measure is 90 degrees
3) After knowing this you can already add 32+90 and get 122 degrees (32+90=122)
4)Now remember step 1; so you subtract 122 from 180 like so (180-122)
5) After doing so you will get the answer of 58 degrees (180-122=58)
6) So now you solution is x=58
