There are 12 more of white and blue cars than silver and red cars

Step-by-step explanation:

Step 1 :

Number of black cars counted by Ed = 23

Number of red cars counted by Ed = 9

Number of blue cars counted by Ed = 17

Number of white cars counted by Ed = 25

Number of silver cars counted by Ed = 21

We need to determine how many more white and blue cars are there than silver and red cars

Step 2  :

Total of white and blue cars = 25 + 17 = 42 cars

Total of sliver and red cars = 21 + 9 = 30 cars

Difference  = 42 - 30 = 12 cars

Hence there are 12 more of white and blue cars than silver and red cars

Step 3 :

Answer :

There are 12 more of blue and white cars than red and silver cars

bazaltina [42]

Answer:

Carl and Alex are wearing hats.

Step-by-step explanation:

If Bob doesn't isn't wearing a hat, then Carl is, so Carl clearly is wearing a hat.

Now let's look at Alex. If he wasn't wearing a hat, then Bob would be wearing one. (If Alex doesn't wear a hat, then Bob wears

a hat). The logical conclusion is that Alex must be wearing a hat as well.

The area of a rectangle is 99 ft^2, and the length of the rectangle is 7 more than double the width. Find the dimensions of the
Sergio039 [100]

Answer:

width =5.5ft

length =18

Step-by-step explanation:

w=x

L=2x+7

area=w*L

99 = x(2x+7)

99=2x^{2} +7x

2x^{2} +7x-99=0

2x^{2} +18x-11x-99=0

2x(x+9)-11(x+9)=0

(2x-11)(x+9)=0

2x-11=0

2x=11

x=11/2

x=5.5

L=2x+7=2*5.5+7=11+7=18

HELP DUE TODAY PLSSS
pashok25 [27]

Answer:

x=12

Step-by-step explanation:

32/2x = x/9; because the triangles are similar

32 = 2x^2/9

288 = 2x^2

144 = x^2

x = 12 or x = -12, but the latter is nonsensical.
