The first number plus the second number equals 83, the first number
minus the second number equals 33. What are the two numbers?
Answer:
I hope this helps
Step-by-step explanation:
So the way to handle a problem like this is to rewrite the three numbers in terms of their relationship to one of the three numbers. Let's call the numbers x, y, and z, where x is the first number, y is the second, and z is the third.
We know x + y + z = 83.
Since the third number is twice the second, we say that z = 2y.
Since the second number is seven less than the first, we say that y = x - 7. We can rewrite this as x = y + 7.
Now all three can be written in terms of y.
x + y + z = 83
(y + 7) + y + 2y = 83
4y + 7 = 83
4y = 76
y = 19
The second number is 19. The first is 19 + 7 or 26, and the third is 2 times 19 or 38.
A check reveals that 26 + 19 + 38 = 83.
What is the measure of angle N?
=========================================================
Work Shown:
Apply the law of sines
sin(N)/MO = sin(O)/MN
sin(N)/18 = sin(17)/6
sin(N) = 18*sin(17)/6
sin(N) = 0.87711511416821 ................. which is approximate
N = arcsin(0.87711511416821)
N = 61.296295678111
N = 61 degrees approximately
----------------------
Notes:
Arcsine is the same as inverse sine. Your calculator is likely to have a button labeled [tex]\sin^{-1}[/tex] to indicate inverse sine.There are two solutions to sin(N) = 0.877; however, the other solution for N is larger than 90. This triangle your teacher is showing appears to be an acute triangle where every angle is less than 90 degrees. Technically two triangles are possible with these current given sides and angle.solve a variable source
x-7=15
Answer:
x = 22
Step-by-step explanation:
x = 7 + 15
x = 22
Answer:
x = 22
Step-by-step explanation:
1x - 7 = 15
1x = 15 + 7
1x = 22 (divide both sides by the first number/1 to get x)
1x/1 = 22/1
x = 22

Suzie drew the line of best fit on the scatter plot shown.
A graph is shown with scale along x axis from 0 to 10 at increments of 1 and scale along y axis from 0 to 15 at increments of 1. The ordered pairs 0, 3 and 1, 3 and 2, 4 and 3, 7 and 4, 6 and 5, 8 and 6, 10 and 7, 10 and 8, 12 and 9, 14 and 10, 15 are shown on the graph. A straight line joins the ordered pairs 0, 3 and 10, 15.
What is the approximate equation of this line of best fit in slope-intercept form?
