Answer:

Tank A

Step-by-step explanation:

add it all up

4+8+12+16+20 = 60 5+10+15+20+25 = 75

60/75 = 4/5 = 0.8

2+4+6+8+10 = 30 3+6+9+12+15 = 45

30/45 = 2/3 = 0.667

0.8 is more than 0.667

Tank A has more fish.

Answer:

The number of students attended was 334 and the number of non students attended was 127

Step-by-step explanation:

Let

x ----> the number students attended

y ----> the number of non students attended

we know that

$x+y=461$ ----> equation A

$3.50x+5.50y=1,867.50$ ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (334,127)

see the attached figure

therefore

The number of students attended was 334 and the number of non students attended was 127

Step-by-step explanation:

Well, I used to do the math, but after using Acellus a while, I found Symbolab.

It's suuuper handy with Algebra. I highly recommend.

How I found this intercept was enter:

intercept -2x+8y=-32

and bam it lists you all intercepts!

Solve for x: 2(x + 3)2 − 4 = 0

Answer:

Option D) x = −4.41, −1.59

Step-by-step explanation:

We are given the following expression in the question:

$2(x + 3)^2 - 4 = 0$

Solving the above expression, we get:

$2(x + 3)^2 - 4 = 0\\2(x^2+9+6x)-4=0\\\text{Identity: }(a+b)^2 = a^2 + b^2 + 2ab\\2x^2+18+12x-4=0\\2x^2+12x+14=0\\\text{Using the quadratic formula:}\\ax^2 + bx +_ c = 0\\\\x = \displaystyle\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\text{Puting a = 2, b = 12, c = 14}\\\\x = \displaystyle\frac{-12\pm \sqrt{(12)^2-4(2)(14)}}{2(2)}\\\\x = \frac{-12 \pm 5.65}{4}\\\\x = \frac{-12 + 5.65}{4}, \frac{-12-5.65}{4} = -1.5875, -4.4125 \approx -1.59, -4.14$
