$11.\\2p+5r=q\ \ \ \ |subtract\ 5r\ from\ both\ sides\\\\2p=q-5r\ \ \ \ |divide\ both\ sides\ by\ 2\\\\\boxed{p=\dfrac{q-5r}{2}}$

$17.\\\dfrac{2}{5}(z+1)=y\ \ \ \ |multiply\ both\ sides\ by\ \dfrac{5}{2}\\\\z+1=\dfrac{5}{2}y\ \ \ \ |subtract\ 1\ from\ both\ sides\\\\\boxed{z=\frac{5}{2}y-1}$

A rope to length 30m is divided in the ratio 2:3. calculate the length of the longest

Vlada [557]

longest part = 18 m

add the parts of the ratio 2 + 3 = 5

divide 30 by 5 to find the value of 1 part of the ratio

$\frac{30}{5}$ = 6 ← 1 part

2 parts = 2 × 6 = 12 m

3 parts = 3 × 6 = 18 m ← longest part

A hose dispenses 1,413 cm³ of water every minute into a cone with a radius of 60 cm and a height of 150 cm. How long will it tak

QveST [7]

I hope this helps you

Volume of cone =1/3.pi.r^2.h

Volume of cone =1/3.3,14.60^2.150

Volume of cone =565.200

if 1,413cm^3 in one minute

565.200 cm^3 in ? minutes

?.1,413=565.200

?=400 minutes

1 hour =60 minutes

? hour =400 minutes

?=400/60

?=20/3 hour

How do you solve this math problem-2(x+3y)=18

ss7ja [257]

Greetings!

Solve for <em>x</em>.
$-2(x+3y)=18$
Distribute the Parenthesis. <em>How?</em> Multiply all of the terms inside the parenthesis by the number outside the parenthesis.
$(-2)*x+(-2)*3y=18$
$-2x-6y=18$
Add 6y to both sides.
$(-2x-6y)+6y=(18)+6y$
$-2x=18+6y$
Divide both sides by -2.
$(-2x)/-2=(18+6y)/-2$
The Answer Is:
$x=-9-3y$
$x=-3y-9$

Hope this helps.
