Answer:
1 : 4 : 2.
Step-by-step explanation:
Ratio is 14:56:528
Divide each number by 14 to get the answer:-
1 : 4 : 2.
Answer:
a)
x/25 = 7/2 --> x = 25 * 7/2 = 87.5 miles
b)
x = 45/75 = 0.6 = 60%
c)
x = 1/(1/24 + 1/30) = 13 1/3 minutes
d)
x/2 + x/6 = 12 --> x = 18
Area of circle B = 16pi
16*36/360 = 1.6 pi ~ 5.024 units^2
So, standard form basically takes the shape of Ax+By=C. You want all of your variables to be on the left side and your constant on the right. There can also be no fractions!
In your case, since you didn't mention a y value for y, your line is y=-3/2x+6
first we get rid of the fraction by multiplying both sides of the equation by 2:
(2)y= (-3/2x+6)(2) and get
2y=-3x+12
now all there is left to do is get x to the other side by adding it to both sides:
3x+2y=12 is your final answer
The equation is saying that -3x+10=5x-8. Once you get all the same terms on one side, you get 18=8x. That would end up being a decimal number, instead of a whole number. The x values would either have to be -4x or 6x in order to make the problem equal
