Multiply all terms by 6 to eliminate fractions
3x+24= -4x+3

Add 4x to both sides
7x+24=3

Subtract 24 from both sides
7x=-21

Divide both sides by 7
x=-3

Final answer: x=-3

Check:
1/2(-3)+4=-2/3(-3)+1/2
-1.5+4= 2+0.5
2.5=2.5

boyakko [2]

I'll go slow:

2\sqrt 7 - \sqrt{28}

=2 \sqrt 7 - \sqrt{4 \cdot 7}

=2 \sqrt 7 - \sqrt{4} \cdot \sqrt{7}

=2 \sqrt7 - 2 \sqrt 7

=0

Answer: B  rational and equal to 0.

Amlyah increased her bench press
NikAS [45]
<h3>Answer:  20% increase</h3>

======================================================

Explanation:

A = old value = 110

B = new value = 132

C = percent change

C = 100*(B-A)/A

C = 100*(132-110)/110

C = 20%

The positive C value means we have a percent increase, which corresponds to the fact that A = 110 increases to B = 132.

The B-A = 132-110 = 22 portion up top indicates that the increase is 22 pounds, which when divided over 110, gets us 22/110 = 0.20 = 20%

---------------

Checking the answer:

20% of 110 = 0.20*110 = 22

She's able to lift 22 extra pounds on top of the 110 pounds she can handle previously, so she can now lift 110+22 = 132 pounds. The answer is confirmed.

An oil tanker breaks apart and starts leaking. As time goes on, the rate at which the oil is leaking out will diminish. Suppose
Alborosie

Answer:

62.77 million gallons

Step-by-step explanation:

Given,

The function that shows rate of leaking oil per minute in after t hours,

R(t) = \frac{0.7}{1+t^2}

∵ 1 hour = 60 minutes ⇒ 3 hours = 180 minutes,

Hence, the quantity of oil leaked out in the first 3 hours,

V(t) = \int_{0}^{180} R(t) dt

=\int_{0}^{180} \frac{0.7}{1+t^2} dt

=0.7 \int_{0}^{180} \frac{dt}{1+t^2}

=0.7[tan^{-1}(t)]_{0}^{180}

=0.7(tan^{-1}(180) - tan^{-1} (0))

=0.7(89.68)

= 62.77 million gallons
