Hello!
Ok so we have given values of angle 4 and angle 2. Sum of interior angles of a triangle equal 180deg. So if angle 4 is 120deg that makes the measure of angle 3 the supplement angle, equal to 180-120=60deg. So then we have angle 1 equal to 180 - 60 - 35= 85deg. Then from that we can conclude the measure of angle 5 is equal to 95deg.
Hope this helps! Any questions please ask! Thank you!
20/100= x/0.4 then cross multiply 20/250=x which 0.08 the answer is 0.08

It's not a typo that both answers are 24
======================================================
Explanation:
Each time the weight goes up by 1 ounce, the cost goes up by 24 cents. So the unit cost is 24 cents per ounce. This is exactly the slope of the line because the slope is the rate of change. It tells us how fast something is changing.
You can use the slope formula to answer this question, but I think it's easier to simply locate the point (1,24) and then note that slope = rise/run = y/x = 24/1 = 24. This shortcut only works because the line goes through the origin.
The equation of this line is y = 24x
x = number of ounces
y = cost in cents
First line because 4(2a+1)=8a+4 and 9a+4-(8a+4)= a
Second line because a times 2 =2a and 2a+1-2a=1
<span>Although the second equality is more or less obvious since 2a+1 leaves a remainder of 1 when divided by a.</span>
