Dave delivered 52 newspapers all together on Saturday and Sunday. He delivered 8 more newspapers on Sunday than on Saturday. How

Harman [31]

Let x=papers on Saturday and y=papers on Sunday

First make equations for the information given to you

x+y=52 (total papers) and y= x+8 (he sold 8 more on Sunday)

then since you know y=x+8 then substitute it in the other equation like so

x+(x+8)=52 which means 2x+8=52 which means 2x=44 and therefore x=22

the problem however asks for sunday and not saturday, so solve for y now

y=x+8 which means y=22+8 which means y=30

He sold 30 papers on Sunday

Stella [2.4K]

Answer:

166.72

Step-by-step explanation:

A= 2(wl+hl+hw)

A= 2(3.2×8.5+4.8×8.5+4.8×3.2)

A= 2(27.2+40.8+15.36)

A= 2(83.36)

A= 2×83.36

A= 166.72

Whats the distance between (-8,-7) (8,-4)

balandron [24]

To find the distance between points, use the distance formula.

Distance formula: $\sqrt{ (x_{2} - x_{1})^{2} + ( y_{2} - y_{1})^{2} }$

Plug in your values for $x_{2}, x_{1}, y_{2}, y_{1}$ using (-8, -7) and (8, -4) and solve.

$\sqrt{(8 - (-8))^{2}+(-4 - (-7))^{2}}$
$\sqrt{(8+8)^{2}+(-4+7)^{2}}$
$\sqrt{(16)^{2}+(3)^{2}}$
$\sqrt{256+9}$
$\sqrt{265}$ ≈ $16.28$

Answer:
Approximately 16.28 units.
