Answer:

QR = 5.

Step-by-step explanation:

Because the parallelograms are similar then the corresponding sides are in the same ratio.

So AB / PQ = BC / QR

9/3 = 15 / QR

15 / QR = 3

QR = 15/3

= 5. (answer)

Answer: $y=8x-25$

Step-by-step explanation:

Given

Line passes through $(3,-1)\ \text{ and}\ (4,7)$

Equation of line when it passes through two points $(x_1,y_1),(x_2,y_2)$

$\Rightarrow \dfrac{y_2-y_1}{x_2-x_1}=\dfrac{y-y_1}{x-x_1}$

Insert the values

$\Rightarrow \dfrac{7+1}{4-3}=\dfrac{y+1}{x-3}\\\\\Rightarrow \dfrac{8}{1}=\dfrac{y+1}{x-3}\\\\\Rightarrow 8x-24=y+1\\\Rightarrow y=8x-25$

Please help me answer this question.

$\bf \textit{hmm how much is 0.25 of the pizzas?}\quad 0.25\cdot 40\implies \boxed{10}\leftarrow Ronnie
\\\\\\
\textit{we know Mack stacked only \boxed{9}}
\\\\\\
\textit{what is the 35\% of 40?}\quad \left(\frac{35}{100} \right)\cdot 40\implies \boxed{14}\leftarrow Kim
\\\\\\
\textit{how many remain?}\quad 40-(10+9+14)\implies \boxed{7}\leftarrow Ada$

so.. that's how many each did, surely you'd know who did the most pizzas.
