There are 4 quarters in a dollar. If you divide 72 by 4 and you do not get a remainder then he can.

2x-1=3/4x+9<br> Help Me Brainilist to whoever explains the best
alexdok [17]

Answer:

x=8

Step-by-step explanation:

normally it would be 2x-1=\frac{3}{4}x+9 so now we have to combine the x into one fraction which will be 2x-1=\frac{3x}{4}+9 now for my way i will be taking the -1 to the other side and when that happens its going to become positive so now the answer will be 2x=\frac{3x}{4}+10 ok so now we have to have the x's to the same side so i have to drag the fraction to the other side and making it positive which will conclude into 1.25x=10 and now 10 divided by 1.25 is 8 so the answer is x=8 (sorry for the ok nows) hope this helped

Answer:

x = 9

Step-by-step explanation:

-5(1 + 1x) = -50

-5 + -5x = -50

-5 + -5x + 5 = -5x

-50 + 5 = -45

-5x = -45

-5x / -5 = x

-45 / -5 = 9

x = 9

What is the lateral area of a right cylinder if the radius of the base is 12 mm and the altitude of the cylinder is 5 times the
lakkis [162]
The lateral area of a cylinder is given by:
Area=πrl+2πr^2
radius,r=12 mm
length,l=5*12=60mm
therefore the lateral area will be:
Area=π*12*60
Area=2,261.95 mm^2
The area of the bases will be:
A=2*π*12^2=904.78 mm^s
The lateral area will be:
2,261.95+904.78
=3,166.73
=3167 mm^2
