Step-by-step explanation:
The total amount that Lantana town needs for a new playground is 14,000 dollars.
Lantana Elementary School raised 5,358 dollars, Lantana Middle School raised 2,834 dollars and Lantana High School raised 4,132 dollars. The total amount that was raised by each school is
5358 + 2834 + 4132 = $12324
Therefore, the remaining amount of money that the town needs to raise is
14000 - 12324 = $1676
-- pick a small number.
-- write it in the equation in place of x
-- solve the equation for y
-- now you have one x and one y; together they make one point on the graph; take your pencil and make a little dot at that point.
-- pick another small number
-- go through this whole procedure again; then you have another x and y; together they make another point on the graph; mark the new point with your pencil.
-- with your pencil and your ruler, draw a straight line between the two points, and KEEP IT GOING in both directions, as far as you want to.
-- your line will cross the y-axis at 3, and every time it goes 1 box across, it'll go 2 boxes up.
THAT'S the graph of this equation.
Answer:
First angle: 60°
Second angle: 30°
Step-by-step explanation:
Let the two angles be signified by the variables x & y.
Let the first angle = x, and the second angle = y.
It is given that:
"The measure[ments] of the complementary angles...": x + y = 90°
"The measure of the first angle is 30 greater than the measure of the second angle": x = y + 30°
Use the system of equations. Plug in y + 30 for x in the first equation:
(y + 30) + y = 90
Combine like terms:
(y + y) + 30 = 90
2y + 30 = 90
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 30 from both sides of the equation:
2y + 30 (-30) = 90 (-30)
2y = 90 - 30
2y = 60
Next, divide 2 from both sides of the equation:
(2y)/2 = (60)/2
y = 60/2
y = 30°
Plug in 30 for y in one of the equations:
x = y + 30
x = (30) + 30
x = 60°
Your answers:
First angle: 60°
Second angle: 30°
