84/7=12
The scale factor is 12 from triangle DCE to triangle BAC.

12(x)=156-x
12x=156-x
13x=156
x=12 (proving)

156-12=144

The answer is A) 144

out of a group of zebras 6/5 times the square root of the number of zebras are playing on the shore of the tank remaining six ar
MatroZZZ [7]

Answer:

Step-by-step explanation:

(6/5)√x = x - 6

(36/25)x = x² - 12x + 36

0 = x² - 13.44x + 36

x = (13.44 ± √(13.44² - 4(1)(36))) / (2(1))

x = (13.44 ± 6.052569702...) / 2

x = 3.69371... zebras

or

x = 9.74628... zebras

In either case we have some odd fractions of zebras hanging around. This makes me highly suspect that the question is misreported

ki77a [65]

Answer:

79 people can only be in this so we have 53 kids so 53 * 4 = 212

Step-by-step explanation:

However, there is 53 kids to find how many adults you will have to do 79 - 53 which that = 26 so 26 adults were there. so 26 * 8.50 = 221.

To fine how much money they earn you will just have to add them up so

$212 + $ 221 = $433 so they didn't really earn the amount of money they really want which is $ 460.

35 is what percent of 150? Enter your answer in decimal form to the nearest hundreth.
Sophie [7]

Answer:

23.33%

Step-by-step explanation:

Solution for 35 is what percent of 150:

35: 150*100 =

(35*100): 150 =

3500: 150 = 23.33

Now we have: 35 is what percent of 150 = 23.33

Question: 35 is what percent of 150?

Percentage solution with steps:

Step 1: We make the assumption that 150 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100%=150.

Step 4: In the same vein, x%=35.

Step 5: This gives us a pair of simple equations:

100%=150(1).

x%=35(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

\frac{100\%}{x\%}=\frac{150}{35}

Step 7: Taking the inverse (or reciprocal) of both sides yields

\frac{x\%}{100\%}=\frac{35}{150}

Therefore, 35 is 23.33% of 150.

Plz help me solve this question ASAP without using algebra, Thank u‼️

Let cost of 1 box of red pen = x

Let cost of 1 box of black pen = y

Gaga bought 5 red box and her sister 4 black box then total cost is given by

5x+4y

Given that total cost was $44

so equation will be 5x+4y=44...(i)

After exchange

Gaga= 4 red box + 1 Black box

Sister = 1 red box + 3 Black box

then cost for Gaga = 4x+1y

cost for sister = 1x+3y

Given that cost for both after exchange is same so we get

4x+1y = 1x+3y

or 4x-1x = 3y-1y

or 3x = 2y

or 3x/2=y ...(ii)

plug (ii) into (i)

5x+4y=44

5x+4(3x/2)=44

5x+12x/2=44

5x+6x=44

11x=44

x=4

Now plug value of x into (ii)

y=3x/2=3*4/2=12/2=6

Hence cost of 1 box of red pen = $4

And cost of 1 box of black pen = $6

---

If you want to get solution without solving both equations then just graph both equations and find the intersection point.

You will see that graph intersect at (4,6) which gives x=4, y=6

If f(x) =3x and g(x) =2x, what is (g*f)(x)
alekssr [168]

We are given f(x) =3x and g(x) =2x

Now we have to find (g*f)(x).

so (g*f)(x) means we multiply f(x) and g(x).

So multiplying 3x and 2x,

3x * 2x = 6x²

So (g*f)(x) =6x²
