Answer:

23 starfish, 7 octopi

Step-by-step explanation:

x=starfish

y=octopi

x+y=30

5x+8y=171

-5(x+y=30)

5x+8y=171

-5x-5y=-150

5x+8y=171

3y= 21

y=7

x+7=30

x=23

23 starfish, 7 octopi

Ackie got 3 wrong out of 20 questions on her social studies quiz.What percent did she answer correctly on the quiz

taurus [48]

Answer:

85%

Step-by-step explanation:

If she got 3 wrong then it means she got 20-3 right, so she got 17 questions right.

From there we get the fraction: 17/20

To make the a percentage we times both the top and bottom by 5 (because 20 x 5 = 100)

By doing that we get 17x5/20x5

= 85/100

That is equal to 85%

I need help on this math problem.

OLEGan [10]

B: (0, a)

C should have the same y value as B

D: (a,0)

C should have the same x value as D

So point C is (a,a)

Since point A is on the origin, its point is (0,0)

You use the slope formula and plug in point A and C:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{a-0}{a-0}$

$m=\frac{a}{a}$

m = 1

So the value that belongs in the green box is 1
