Due to the lack of information I assume these are fractions so for 5/35 we times it by 21 and 21 by 35 so they have the same denominator so now we got 105/735 and for 21 we get x/735 so now You put 105/735 and divide by 35 so we get back down to 21 for
3/21 for part 1
Now for part 2 again 15 times 20 and 20 times 15 to equal out the denominators so now we have 240/300 and x/300 so now plug 240 into x and divide down by 15 and now we get
16/20 for part 2
LMK if I am wrong I highly doubt it
Because the distance a car travels is directly related to the time it travels, the distance varies directly with the time: d=a*t. "a" would be the constant of variation. Just substituted the given values(300 and 5) into the equation, and you would get 300=5a. Divide both sides by 5 and you get a=60. So, the constant of variation is 60
Answer:
6
Step-by-step explanation:
Answer:
h = -b/2a
Step-by-step explanation:
to find the vertex (h,k)
find h ushing h = -b/2a
then substitute x with h to find k
ie. k = -4h2 + 2h - 7
