First:
X = 15
Step-by-step explanation:
So the two angles are congruent, or they are the same angle. So you write the equation as 5x + 9 = 84.
5x + 9 = 84
-9 -9
5x = 75
(divide) 5 from both sides
x = 15
Second:
X = 27
Step-by-step explanation:
For this one I believe the answer is X = 27 because both equations should equal 180 degrees.
So you write the final equation:
(x + 72) + (3x) = 180
-72 -72
(combine X's):
4x = 108
Divide both sides by 4
X = 27
Third:
X = 40
Step-by-step explanation:
For this one, the angles match again, so you write it s:
4x - 50 = 2x + 30
+50 +50
4x = 2x +80
-2x -2x
2x = 80
Divide both sides by 2
X = 40
End

Ms. Reynold's sprinkler system has 4 stations that water all parts of her front and back lawn. Each station
runs for an equal amount of time. If it takes 36 minutes for the first 3 stations to water, how long does it
take to water all parts of her lawn?
It will take 46
minutes for Ms. Reynold to water her lawn.
Answer:
It will take 48 minutes to water all parts of her lawn.
Step-by-step explanation:
Each section runs for an equal amount of time
3 sections have run for 36 minutes
36 divided by 3 is 12, meaning each section runs for 12 minutes
12 times 4 is 48

Answer:
a) 1.70 L
b) 16 breaths per minute
Step-by-step explanation:
a) The maximum value of v(t) occurs when the sine function is at its maximum value of 1. In that case, the volume is ...
1.27 +0.43×1 = 1.70 . . . liters
__
b) One full breath cycle takes a period of time that makes the argument of the sine function be 2π. The that time period is ...
1.71t = 2π
t = 2π/1.71 ≈ 3.6744 . . . seconds
Then the number of breaths per minute is ...
(60 seconds/minute)/(3.6744 seconds/breath) ≈ 16.33 breaths/minute
The person takes about 16 breaths per minute while sleeping.

What is an equation of the line that passes through the point (−4,5) and is perpendicular to the line 4x+y=7
Answer:
[tex]y = \frac{1}{4} x + 6[/tex]
Step-by-step explanation:
rewrite the original equation
[tex]4x + y = 7 \\ y = - 4x + 7[/tex]
perpendicular line has a negative reciprocal slope. I will use this slope and substitute the points to find our y-intercept
[tex]5 = \frac{1}{4} ( - 4) + b \\ 5 = - 1 + b \\ b = 6[/tex]

x
.
9514 1404 393
Answer:
x = -19 or 72
Step-by-step explanation:
The range of the given numbers is 5 to 48. In order for x to make the range be 67, the value of x must be 67 less than 48, or must be 67 greater than 5.
x is 48 -67 = -19
or
x is 5 +67 = 72

Find the equation of the linear function represented by the table y 6 9 12 15 x 1 2 3 4
Answer: y = 3x + 3
Step-by-step explanation:
We know the linear function as following:
y = mx + b
m is the slope of the equation. b represents the y-intercept.
To find m, we divide the rate of change of y by the rate of change of x. We know that the rate of change y is +3 because we add three each time in order to find the next value. The rate of change of x is +1 because we add one each time to find the next value. So m would be:
m = 3/1
m = 3
Our linear equation is now as following:
y = 3x + b
In order to find b, we should first substitute a coordinate in the equation above.
y = 3x + b
6 = 3(1) + b
Then, we multiply 3 with 1
6 = 3 + b
Finally, we substract 3 on both sides. Now we've got our b value.
b = 3
Now our equation should look like this.
y = 3x + 3
To verify if the equation, we should substitute another coordinate, and verify if each side of the equation is equal.
y = 3x + 3
15 = 3(4) + 3
15 = 12 + 3
15 = 15
So we now know that the equation is indeed correct.
Answer:
y = 3x + 3Step-by-step explanation:
As per given table we have ordered pairs:
(1, 6), (2, 9), (3, 12), (4, 15)Find the slope and y- intercept to work out the equation.
y = mx + bThe slope:
m = (9 - 6)/(2 - 1) = 3/1 = 3The y -intercept:
6 = 3*1 + b6 = 3 + bb = 3The equation is:
y = 3x + 3The graph is attached

Holly buys a $22 shirt for 20% off. The tax rate in her city is 6.5%. What is the total amount she paid for the shirt? Round to the nearest cent.
Answer:
$18.74
Step-by-step explanation:
To find the sale price:
22 * 0.2 = 4.4
22 - 4.4 = 17.6
or, you can just multiply by 0.8, so you wont need to subtract later
22 * 0.8 = 17.6
Then, you need to find the tax amount:
17.6 * 6.5 = 1.144
17.6 + 1.144 = 18.744
Round
18.74

Paul is shopping for laundry detergent. At the grocery store, the liquid detergent is pricedat $14.99 for 64 loads of laundry and the same brand of powder detergent is priced at$15.99 for 80 loads. Which is the better buy, the liquid or the powder detergent?
Answer:
15.99 is better
Step-by-step explanation:
because when working with dividing decimals we need to make it a whole number so we would move it over to the right till it is a whole number (which is two spaces) but first we need to put our decimal in our quotient so two spots. and 1499 divided by 64 equals 23.421875 and 1599 divided by 80 equals 19.9875 so the 15.99 dollar one is a better deal.
