Turn both examples to Slope intercept form (Y=MX+B) Make the questions where one part, X or Y cancel each other out. Then, with Y=X/Y+b, solve the equation to get X/Y. Let's say you found X. Substitute that number for the X in the other equation and solve to get the Y. And there you have it, your coordinates

timama [110]
One pound= 16 ounces 

2 x 16 = 32 ounces = 2 pounds

2/5 can also be expressed in decimal form as .4

so 32 x .4 = 12.8

and then 3/10 also is .3 

so 32 x .3 = 9.6 

add the two 12.8 + 9.6 = 22.4

If the perimeter of a rectangular picture frame must be less that 200 in, and the width is 36 in. what must the height H of the
fgiga [73]

Answer:

w = width

h = height

2(w+h) < 200

w + h < 100

since w = 36, then

36 + h < 100

h < 100 - 36

h < 64

Step-by-step explanation:

The perimeter of the rectangular picture frame can be calculated by the equation,

                                 2h + 2w = P

where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,

                                2h + 2(36 in) < 200

The inequality gives h as,

                                          h < 64

Thus, the answer is letter A.

I dont understand this at all. I really need help! ​
Westkost [7]

Hello!

\large\boxed{x^{4}}

Recall that:

\sqrt[z]{x^{y} } is equal to x^{\frac{y}{z} }.  Therefore:

\sqrt[3]{x^{2} } = x^{\frac{2}{3} }

There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:

(x^{\frac{2}{3} })^{6}  = x^{\frac{2}{3}* 6 }  = x^{\frac{12}{3} } = x^{4}
