in a survey of 100 cars,47 were white,23 were blue and 30 were red. express each of these numbers as a percentage of the total.

white- 47%   Blue-23% Red- 30%

Step-by-step explanation:

White cars- (47/100)*100= 47%

Blue cars- (23/100)*100=23%

Red cars- (30/100)*100=30%

White 47 percent, 23 percent blue 30 percent red.

47+23+30=100 percent

Step-by-step explanation:

So to get the percentages you first have to get the numbers that you need in this case it is 47,30,and 23.

After that we have to first multiply the numbers(47,30,23)by 100 because

100 hundred is our total percent so 47x100=4700 30x100=3000

and 23x100=2300.And 47x100=4700 30x100=3000

and lastly 23x100=2300.So after we multiply the numbers by 100 hundred we have to divide so we see there's 100 cars so we divide by that because that is the total amount of cars and if we divide all our numbers by 100 we will get the answer,

4700/100=47 percent 3000/100=30 percent 2300/100=23 percent

and to check our answer is right we have to add all our number percentages up to see if all the numbers add up to 100.(percentage)so 47+30+23=100

So that means our answer is right.

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
