Answer:
130
Step-by-step explanation:
X is the alternate corresponding angle to 50. 50+y=180
y=130
x and y = the same thing so 130 is the value of x
1/3b+1/3c is the expression assuming bikes are counted as vehicles
Answer:
what do you mean it's not 7 it is 7
Step-by-step explanation:
The value of x is 7
The given parameters are:
\angle BAE = 9x + 2∠BAE=9x+2
\angle BAD = 130^o∠BAD=130
o
Line AE is the angle bisector of \angle BAD∠BAD
This means that:
\angle BAD = 2 \times \angle BAE∠BAD=2×∠BAE
So, we have:
130 = 2 \times (9x + 2)130=2×(9x+2)
Divide both sides by 2
65 = 9x + 265=9x+2
Subtract 2 from both sides
63 = 9x63=9x
Divide both sides by 9
7 = x7=x
Rewrite as:
x = 7x=7
Hence, the value of x is 7
Answer:
a) 
b) 
Step-by-step explanation:
We know that theres a <u><em>linear relationship</em></u> between the rate of the chirping of crickets and the air temperature.
<u><em>The equation of a line is</em></u>:

So, let's name our variables
x= Temperature
y=Rate of the chirping
First of all, we need to find the <u><em>slope</em></u> with the two given points
60ºF , 
80ºF, 
By,


<u>Now, the </u><em><u>equation</u></em><u> between the air temperature and the number of chirps is:</u>


Solving for y,
a) 
b) <u>To calculate the </u><u>rate</u><u> at which the crickets chirp when the </u><u>temperature is 102 ºF</u><u> we need to evaluate y(102)</u>
