Answer:

x=60

Step-by-step explanation:

3/5x + 1/4x=51

4(3/5x) +5 (1/4x)=51

12/20x+5/20x=51

17/20x=51

17x=51(20)

17x=1020

x= 1020/17

x= 60

Answer:

x=60

Step-by-step explanation:

3/5x + 1/4x=51

12/20x+5/20x=51

17/20x=51

17x=1020

x=60

Double-Check:

3/5(60)+1/4(60)=51

180/5+60/4=51

36+15=51

51=51

Hope it helped!

The container that holds the water for the football team is 7/10 full. after pouring out 3 gallons of water, it is 1/2 full. how
Andreyy89
Hello!

So you figure that 7/10-5/10=2/10 that leave you with 1/5 left over. So if you take that into effect, all you have to do it multiply those 3 gallons by 5. Which gives you 15. So, your answer would be 15 gallons. 

I hope this helped!

I am, yours most sincerely

Solve for x 9x-3-8x=7-x
Kipish [7]

Answer:

x = 5

Step-by-step explanation:

First, we move all variables to one side of the equation. (Don't forget to change signs.)    

9x - 8x + x = 7 + 3

Then, we simplify

x + x = 10

2x = 10

10 divided by 2 is equal to 5.

Therefore, x = 5

Hope this helps!

Write the equation of the line in slope intercept form that passes through the point (6,-2) and is parallel to the line y = -3x
harina [27]

Answer:

For a line to be parallel it must have the same slope. So the slope of the new equation is 6.

The slope intercept form is y=mx+b. And we have a point (3,-5). Plug in what we know....

-5=6(3)+b

Solve for b (the y-intercept)

b= -23

Therefore.... y=6x-23

??? does that help????

Which of the following best describes a cylinder?
alexandr1967 [171]
Hey there!

The shape being described in letter A is a prism. A prism has two polygonal shapes on either end that can be any shape consisting of three or more sides. This won't be your answer, since cylinders have circular bases on either side. 

The shape being described in letter B is a cylinder. Not sure why they needed to throw in the plane part, but this is the only answer that describes the bases as being circular (or, as they put it, discs). 

The shape being described in letter C is a pyramid. If a shape has a polygonal base and meets at a point at the other end, it will be a pyramid. Obviously, a pyramid only has one end, meaning that this isn't your answer. 

The shape being described in letter D is a cone. Again, if a shape has a base and meets at a point, it will be a pyramid. However, in the case of a cone, the base will be circular and the other side will meet at a point. The entire shape will be rounded where a pyramid would have edges. Again, not your answer. 

Your answer will be B. Hope this helped you out! :-)
