Answer: x = 11, y = 9
Step-by-step explanation:
To solve for x, set the sides equal to each other:
7x + 27 = 10x - 6
Add 6 to both sides:
7x + 33 = 10x
Subtract 7x from both sides:
33 = 3x
Divide both sides by 3:
11 = x
(Which is the same as x = 11)
Now, to solve for y, since they don’t give you the other side, you know that the straight line is 180° so:
7x + 27 + 9y - 5 = 180
Plug in your x:
7(11) + 27 + 9y - 5 = 180
77 + 27 + 9y - 5 = 180
Add like terms:
99 + 9y = 180
Subtract 99 from both sides:
9y = 81
Divide both sides by 9:
y = 9
Hope this helps!
Step-by-step explanation:
it is a line (as the variable x is only occurring with the exponent 1, this makes this a linear equation or simply a line).
all we need to do is find 2 points, mark them in the graph, and the draw a line through both points (and beyond these points).
the first point for me is always for x = 0.
f(0) = 4×0 - 4 = -4
so, the first point is (0, -4)
and for a second point let's pick e.g. x = 2
f(2) = 4×2 - 4 = 4
so, this second point is (2, 4).
Answer:
52,53,54
Step-by-step explanation:
x, x+1, x+2
2x+1=x+53
x+1=53
x=52
x+1=53
x+2=54
Answer:
1 / 5
Step-by-step explanation:
Given that:
Number of white marbles = 5
Number of blue marbles = 3
Number of green marbles = 7
Required is the approximate probability of drawing 2 green marbles, Note that drawing is done without replacement :
Probability = required outcome / Total possible outcomes
Total possible outcomes = sum of all marbles = (5 + 3 + 7) = 15 marbles
First draw:
P(Green) = 7 / 15
Second draw:
Required outcome = 7 - 1 = 6
Possible outcomes = 15 - 1 = 14
P(green) = 6 / 14
Probability of drawing out two green marbles :
(7/15 * 6/14) = 42 / 210 = 1 / 5
Answer:
3x-3=18
Step-by-step explanation:
3(x-3)=18
3x-9=18
x=9
3.34=3x-1
3x=35
x=35/3
