Find the measure of the missing angle.
a
20°
Answer:
160 degrees
Step-by-step explanation:
That is a straight line, meaning that the sum of a and 20 has to equal 180.
a + 20 = 180
a = 180-20
a = 160

Answer:
6 hours
Step-by-step explanation:
( 7h + 5h)/2 =6h
ANSWER:
It would take them about 3 hours to paint the room together.

Which graph represents a linear function?
Answer:
Please check the explanation below.
Step-by-step explanation:
Note: As you forgot to mention the graphs of a linear function. But, let me clear your concept with an example of a linear function.
We know that linear function is of the form
y = mx+b
where
m is the slopeb is the y-interceptWe know that the graph of a linear function is a straight line because the highest power of the exponent of the x variable is 1.
Thus, y = mx+b represents a straight line.
For example,
Let the linear function
y = 2x+3
comparing with the linear function of the form y = mx+b
The slope = m = 2The y-intercept b = 3As the highest power of the exponent of a variable is 1, therefore y = 2x+3 represents a straight line.
The graph of the linear function y = 2x+3 is also attached below.

Step-by-step explanation:
1) Number of white chocolate bars = x
Number of dark chocolate bars = y
Total bars = 15
x + y = 15 --------------(I)
Total cost = Php. 340
20x + 25y = 340 ----------------(II)
2) We can use elimination method to solve this equations.
Multiply equation (I) by (-20) and then add the equations.
(I)* (-20) -20x -20y = - 300
(II) 20x + 25y = 340 {Now add and x will be eliminated}
5y = 40
y = 40/5
y = 8
Substitute y = 8 in equation (I)
x + 8 = 15
x = 15 - 8
x = 7
3) Number of dark chocolate bars = 8

The distance in miles in the distance in inches vary directly on a map. The legend on the map shows that 16 miles are represented by 0.5 inches. What is the actual distance between the two cities if they are 3 inches apart on the map? In the situation distance in =x.
A) 96 miles
B)72miles
C)80miles
D)104miles
The actual distance between the two cities is 96 miles.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that the map shows that 16 miles are represented by 0.5 inches.
Let x miles would be the actual distance between the two cities
When they are 3 inches apart on the map
According to the given situation, we can write the ratio would be as:
16 miles : 0.5 inches = x miles : 3 inches
⇒ 16/0.5 = x/3
Apply the cross-multiplication operation,
⇒ 0.5x = 48
⇒ x = 48/0.5
⇒ x = 96
Therefore, the actual distance between the two cities is 96 miles.

3. Given the function f(x)=x^2+4x-12:
a. Identify the zeros using factorization.
Answer:
x = -6, 2
Step-by-step explanation:
A zero is the x-value of a point on the x-axis that the graph intersects. Knowing this, we can set the function itself to 0 to find the zeros.
1) Set the function to 0.
[tex]x^2+4x-12 = 0[/tex]
2) Factor out the polynomial. Ask yourself, what are two numbers that have a product of -12 and add up to 4? (In this case, it's 6 and -2.)
[tex]x^2+4x-12 = 0\\(x+6)(x-2) = 0[/tex]
3) Look at the answer from the last step. What do the x's have to equal in order for equation to equal 0? They have to be -6 and 2. Therefore, those are the zeros.

What is the solution to the equation 6- t = 2t
Answer:
t=2
Step-by-step explanation:
Literally just move all the common like terms onto one side.
6=3t
It is usually prefered to have the variables on the left and the coefficients on the right so you would flip your equation.
3t=6
Then you get t by itself by dividing by 3. Your final answer should be 2.

I need help with this
ahhh please help i don’t understand thissss
Answer:
24y^3/x^5
Step-by-step explanation:
Since 6x and 4x are not in a parentheses, they are not being powered by anything. Therefore, those stay on the numerator side.
Anything to the power of something times another to the power of something is always added together. Since -1 + (-4) is -5, x would end up having a power of -5, which would just make it go on the denominator side with just a power of 5.
Same rule with y follows. This would make it 5+ (-2) = 3. Since this is a positive power, it stays at the numerator side.
