Answer:

20%

Step-by-step explanation:

An equation is 14=x/100*70 or 14=(x%)*70, either one works

solve for x:

14=x/100*70
14/70=x/100 (Divide each side by 70)
1/5=x/100 (Simplify 14/70)
100/5=x (Multiply each side by 100 to isolate x)
x=20 (Simplify 100/5)
20% (Rewrite as a percent)

hope this helps!!

Answer:

see explanation↓

Step-by-step explanation:

(a)

$(3x+2)-(x+5)=3x+2-x-5$

$(3x+2)-(x+5)=2x-3$

ANSWER: Linear binomial

(b)

$(3x+8)+(4x^{2}-x)=3x+8+4x^{2}-x$

$(3x+8)+(4x^{2}-x)=4x^{2} +2x+8$

ANSWER: Quadratic trinomial

(c)

$(x^{2}+7x)-(x^{2}+5)=x^{2}+7x-x^{2}-5$

$(x^2+7x)-(x^2+5)=7x-5$

ANSWER: Linear binomial

(d)

$(2x+8)+(3x^2-2)=2x+8+3x^2-2$

$(2x+8)+(3x^2-2)=3x^2+2x+6$

ANSWER: Quadratic trinomial

(e)

$(x^2+5x-2)+(8-5x)=x^2+5x-2+8-5x$

$(x^2+5x-2)+(8-5x)=x^2+6$

ANSWER: Quadratic binomial

mr Goodwill [35]

The answer for A is,

$a = 5 + \frac{ \sqrt{6} }{ \sqrt{5} } - \sqrt{6} - \sqrt{6b}$

And the answer for B is,

$b = - 1 + \frac{5 + \frac{ \sqrt{6} }{ \sqrt{5} } - a }{ \sqrt{6} }$

hope it helps.

= Number of video game rentals * rental price of video game

= 5 * 2.10

= $10.50

Total amount spent on DVD rentals:

= Number of DVD rentals * rental price of DVD

= 6 * 3.70

= $22.20

Total spent on both:
