Use a unit rate to find the unknown value 16/32= /14

1 answer:

7 0

Okay. So this is already set up as a proportion. Cross multiply the values in order to get 224 = 32x. Now, divide each side by 32 to isolate the variable. 224/32 is 7. x = 7. There. The unknown value is 7.

Answer:

64/49

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)^c = a^(bc)

(a^b)(a^c) = a^(b+c)

a^-b = 1/a^b

a^0 = 1

_____

Using these rules, we can simplify the given expression to ...

$\left(\dfrac{8\cdot 4\cdot 2}{8\cdot 7}\right)^2\times\left(\dfrac{8^0}{7^{-3}}\right)^3\times 7^{-9}\\\\=\dfrac{8^2}{7^2}\times(8^{0\cdot 3}\cdot 7^{3\cdot 3})\times 7^{-9}\\\\=\dfrac{64}{49}\times(8^07^{9-9})=\boxed{\dfrac{64}{49}}$

Answer:

Here's what I get

Step-by-step explanation:

a. Write an equation

(8x + 12y)² + (6x + 9y)²= (10x + 15y)²

b. Transform the equation

(i) Remove parentheses

64x² +192xy + 144y² + 36x² + 108xy + 81 y² = 100x² +300xy + 225y²

(ii) Combine like terms.

100 x² + 300xy + 225y² = 100x² +300xy + 225y²

The two sides are the same.

The equation is an identity.

Question of the day.

matrenka [14]

$\lambda = _0^{200}\sum (i)^f = 1+50(i-1-i+1) = 1 + 0i$
From this we know that $\lambda$ lies on the x-axis.
If z = 0, then k = $\lambda$ and point lies on curve L.

I believe the answer is C. It definitely not A or B.
