Step-by-step explanation:
0.1 + 0.2x +0.3 + 0.05x = -2.4
Answer:
x = -11.2
Step-by-step explanation:
0.1 + 0.2x + 0.3 + 0.05x = -2.4
Combine like terms on the left side.
0.25x + 0.4 = -2.4
Subtract 0.4 from both sides.
0.25x = -2.8
Divide both sides by 0.25.
x = -11.2

1. A movie theater sells tickets for $9.00 each. Senior citizens receive a discount of $3.00. One evening the theater
sold 636 tickets and took in $4974 in revenue. How many tickets were sold to senior citizens?
Answer:
250
Step-by-step explanation:
x is adult tix, y is senior tix
9x + 6y = $4974
x+y= 636
x=636-y
9(636-y) +6y = 4974
5724 - 9y + 6y = 4974
-3y = 4974-5724
-3y=-750
y=250

Polynomials are not always closed under which operation?
A)Addition
B)Subtraction
C)Multiplication
D)Division
Answer:
D
Step-by-step explanation:
Polynomials are always closed with addition, subtraction, and multiplication. Division cannot be used to close a polynomial because when you divide two polynomials, its not going to come out as polynomial. All the other operations after completed will create another polynomial.

Weatherman Glenn Burns predicts there to be 4.25 inches of rain on Saturday. On Saturday, it actually rains 6.5 inches. How much percent error was Glenn Burns from being accurate?
Answer:
the prediction was about 35% too low
Step-by-step explanation:
We generally define percent error as the difference between a measurement and an actual value, as a fraction of the actual value. Here, the actual value is 6.5 inches, so we can compute the error to be ...
(4.25 -6.5)/6.5 × 100% = -34.6%
Burns' prediction was about 35% too low.

Explain whether the points (-13,4), (-7,3), (-1,2), (5,1). (11,0), (17, -1) represent the set of all the solutions for the
equation y = -x + (1 point)
Yes, because all the solutions of y x + need to be integer values for an and y,
No, because the point (17, -1) is not on the line that represents the equation y = a +
O Yes, because all of the points that are listed are on the line y = - +
O No, because the set of all solutions of y = -x+ His represented by the line of the equation.

Step-by-step explanation: im pretty sure im wrong, goodnight
calculate E, the amount of euros that has the same value as D U.S. dollars, using the equation E=17/20D=
The given equation is: E=17/20 D , where E=amount of Euros and D= amount of U.S dollar.
Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get.........
E=17/20(1)
E=1/20=0.85
0.85 Euros have the same amount as 1 U.S dollar.

Answer:
4. 120
5. 20
6. 55
Step-by-step explanation:
All straight lines have a degree of 180, so the angle measures all have to add up to 180 degrees.
Answer:
4) 120°
5) 20°
6) 55°
Step-by-step explanation:
4) 180°-60°=120°
5) 180°-160°=20°
6) 90°+35 = 125°
180°-125°=55°

Two angles are supplementary. If one angle measures twice the other, and the number of degrees in the smaller angle.
Answer:
60 Degrees
Step-by-step explanation:
Supplementary means it equals 180 together, so you divide it by 3 because the one is twice as big and you take the smaller answer
[tex]\frac{180}{3} =60[/tex]
Small and large angle are 60° and 120°.
Given that;
Angles are supplementary
Computation:
Assume;
Smaller angle = a
So,
Large angle = 2a
So,
In supplementary
a + b = 180
a + 2a = 180
3a = 180
a = 60
Smaller angle = 60°
Large angle = 2(60)
Large angle = 180°

Find the equation of the linear function represented by the table below in slope-
intercept form.
y=Mx+B
Answer:
y = x + 4
Step-by-step explanation:
Let the equation of the linear function represented by the table is,
[tex]y-y_1=m(x-x_1)[/tex]
where m = slope of the line
And this line passes through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Slope of the given line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the given table two points lying on the function are (-4, 0) and (1, 5).
Slope 'm' = [tex]\frac{5-0}{1+4}[/tex] = 1
Therefore, equation of the linear function passing through (1, 5) and slope 1 will be,
y - 5 = (x - 1)
y = x + 5 - 1
y = x + 4
