Answer:
6
Step-by-step explanation:
So, to start answering this, lets recall the formula for a rectangles volume:
This formula is :
V=h*w*l
Lets plug in what we know, and solve for the missing variable.
We know that height(h) is 7.
We know that width(w) is 9.
We know that volume(V) is 378.
We are missing length(l)
So:
378=7*9*l
To find length(l), we must iscolate it.
To do this, we must get rid of the 7 and 9.
So lets start by dividing 378 by 9:
378/9=7*9/9*l
=
42=7*l
Now lets do the same thing with the 7 to iscolate l:
42/7=7/7*l
=
6=l
So our missing length(l) is 6.
Answer:
l = 6

<span>Round 287.9412 to the nearest tenth.
Lets solve this!
To round to the nearest tenth, you need to know the tenth place--------
In the number, 287.9412, nine is in the tenth place. You need also make sure whether the number next to 9 is greater than 5 or not.
</span><span>287.9412 =287.941=287.94=287.9=288=290
Thus, your answer is 290.
Hope I helped.

15+22(4+11)=x
4+11=15
22*15=330
15+330=345
x=345
Answer:
x=2/3
Step-by-step explanation:
(2x+1)/2 = 2 1/3/4
Multiply 4 on both sides:
2x+1=2 1/3
Rewrite:
2x+1=7/3
Subtract 1 on both sides:
2x=4/3
Divide 2 on both sides:
x=2/3
Thus x=2/3
Hope this helps!
To make it much easier, it should be converted to the slope-intercept form
y = mx + bTo do so, 14x + 34y = 1 turns to:
34y = -14x + 1Divide both sides by 34:
Simplified:
