A food pantry distributes 10-ounce bags of flour. A supermarket donates nine 5-pound bags to the pantry. How many 10-ounce bags

DanielleElmas [232]

Given:
nine 5 pound bags
distributed into 10-ounce bags

1 pound = 16 ounces

9 x 5 pounds = 45 pounds

45 pounds * 16 ounces/lbs = 45 * 16 oz = 720 ounces

720 ounces / 10 ounce bags = 720/10 = 72 bags.

The workers at the food pantry will be able to make 72 bags.

F(x)=ax+b/2 then f^-1 (x-1) =2x-5/2 find a and b

krok68 [10]

From the given inverse function, we have

$f^{-1}(x-1) = 2x - \dfrac52 \\\\ \implies f^{-1}(x) = f^{-1}((x+1)-1) = 2(x+1) - \dfrac52 = 2x-\dfrac12$

By definition of inverse function,

$f\left(f^{-1}(x)\right) = x$

so that

$f\left(2x-\dfrac12\right) = x$

$a\left(2x-\dfrac12\right) + \dfrac b2 = x$

$2ax - \dfrac a2 + \dfrac b2 = x$

$\implies\begin{cases}2a=1 \\\\ -\dfrac a2+\dfrac b2 = 0\end{cases}$

$\implies \boxed{a=\dfrac12}$

$\implies \dfrac b2 = \dfrac a2 \implies \boxed{b=\dfrac12}$

Write the expression 10 + 25 in a different way,

Harman [31]

25+10 is the answer

In the Commutative law of addition, it says that a+b and b+a are the same which makes ab and ba equal to one another.

To prove just add 10+25 and 25+10to show that both results in 35 (aka the same answer)
