CosA = 12/20 which is 3/5
Answer:
13/4 - (13,4) - however your teacher wants you to write it out.
Step-by-step explanation:
Rise (y) over Run (x)
Equation:
y2 - y1
over
x2 - x1
Inputting the numbers, 6 - -7 (aka 6+7) over -3 - -7 (aka -3+7)
6+7 = 13
-3+7 = 4
13/4 - The line is rising moving towards the right.
Hope I helped!
Answer:
n=900
Step-by-step explanation:
the equation is:
197=125+0.08n
72=0.08n
n=900
To start off, you want to make the equations. first, we will make x = chocolate candy and y=caramel candy since thats the order they come in the problem. we know she bought 20 pieces of candy, so we now know our first equation, x+y=20. next, if each chocolate candy costs $.50, that now makes x in our second equation .5x. the y will then be .1y. they then total up to equal $6.80, so our second equation is .5x+.1y=6.8. to then find x, subtract the y from the first equation to get x=20-y. then in the second equation, replace x with y and solve. you then get y=8, so we know britney has 8 caramels. now in the first equation, replace the y to get x+8=20. and now x=12
