30 POINTS!!! Kent won 25% of the games he played on Saturday. If he lost 12 games on Saturday, and no game ended in a tie, how m

Lana71 [14]

Answer:

He won 4 games

Step-by-step explanation:

Percentage of games he lost= 75%

Let the total number of games be $x$

75% of $x$ = 12

$\frac{75x}{100}$ = 12

75 $x$ = 12 x 100

$x$ = $\frac{1200}{75}$

=16

Number of games he won = 16-12

= 4

Answer:

The answer is: the second one

Step-by-step explanation:

(2x + 2)/y = 4w + 2

pass y to the right side 2x + 2 = y(4w + 2)

expand 2x +2 = 4wy + 2y

pass 2 to the right 2x = 4wy + 2y -2

pass 2 to the right x = (4wy + 2y - 2)/2

simplify x = 2wy + y - 1 or = 2yw + y -1

A pair of snow boots at an equipment store in Big Bear that originally cost $80 is on sale for $56. What is the rate of discount

8_murik_8 [283]

Divide the sale price by the original price:

56 / 89 = 0.7

Multiply by 100:

0.7 x 100 = 70%

The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)

How would I graph this inequality?<br> <img src="https://tex.z-dn.net/?f=7x%2B3y%5C%20%20%5Ctextless%20%5C%206-5x" id="TexFormul

Answer:

the graph in the attached figure

Step-by-step explanation:

we have

$7x+3y$

isolate the variable y

Subtract 7x both sides

$3y$

Divide by 3 both sides

$y$

The solution of the inequality is the shaded area below the dashed line

The equation of the shaded line is $y=-4x+2$

The slope of the dashed line is negative $m=-4$

The y-intercept of the dashed line is the point $(0,2)$

The x-intercept of the dashed line is the point $(0.5,0)$

To graph the inequality plot the intercepts and shade the area below the dashed line

using a graphing tool

Please help me with my math homework what is the answer!!!

Dmitry [639]

Answer:

Step-by-step explanation:

The letters are easy enough.

y^3 determines that 3 ys are needed. y^2 is taken in by the cubed.

x^4 determines that 4 xs are needed. x^3 is part of x^4 and you don't need any more xs

12 and 42 are the parts that will cause the problem. Factor them both into prime factors

12: 2 * 2 * 3

42: 2 * 3 * 7

You need two 2s.

You need one 3

You need one 7

LCD = 2 *2*3 * 7 = 84
