Remember slope is
. In the graph we can just pick two points on the line to find the rise and run between. Let's say we choose (0,3) and (1,7). Between those points there is 7-3=4 rise and 1-0=1 run. So the slope is
Since (4y-42) and 2y are opposite angles, they equal to each other which looks like this:
4y-42 = 2y
From there you want to put the y onto one side:
4y-2y-42=0 -----> 2y-42=0
You want to balance the equation out and move the -42 onto the other side so you add it to both sides to get:
2y=42
Then divide both sides by 2 to get:
y= 21
From there you can plug 21 back into the original equation to find each angle.
4(21)-42 = 2(21) ---> 84-42 = 42 ---> 42 = 42
So y = 21 and each angle is 42 degrees
Answer:
The answer is 3
Step-by-step explanation:
0.7*3 = 2.1
Think of it this way
its basically 7 times what equals 21?
then you find out 7 timex 3 = 21
and then put the decimals
0.7 times 3 (0.7 + 0.7 + 0.7) = 2.1
It is b i think what i did is i multiplied the two and got 0.1925 exactly
