Step-by-step explanation:
B/-7 = 4
Cross multiple
-7×4 = B
-28 = B
To figure out the degrees, you would create a ratio.
Since there are 360 degrees in your circle, that would be representative to 100 (because both are the total of what you want to find), and x would be representative to what degrees 65 is equal to.
your ratio should look like,
65/100=x/360
cross multiply and get
65(360)=100x
23400=100x
x=234
It looks hard to read like this, but if you write it out on your paper it should make more sense!
Answer:
15x^2-2x-8
Step-by-step explanation:
i did it on a paper just don't want to write cause its going to be to much to write hope this helps good luck
X = 0.6x + 384 |subtract 0.6x from both sides
0.4x = 384 |divide both sides by 0.4
x = 960
The slope would be 2/3 because that would leave pounds when multiplied by cups.
add 0.5 for the weight of the water jug
y = (2/3)x + 0.5
