Answer:

x=\frac{y+3w}{7}

Step-by-step explanation:

The given equation is

y=7x-3w

We need to solve this equation for x.

Isolate variable x to solve this equation for x.

Add 3w on both sides.

y+3w=7x-3w+3w

y+3w=7x

Divide both sides by 7.

\frac{y+3w}{7}=\frac{7x}{7}

Cancel out common factors.

\frac{y+3w}{7}=x

Interchange the sides.

x=\frac{y+3w}{7}

Therefore, the formula for x is x=\frac{y+3w}{7}.

What is the volume of a hemisphere with a radius of 2.3m round to the nearest tenth of a cubic meter
kodGreya [7K]

Answer: 25.5 m^{3}

Step-by-step explanation:

If the volume of a sphere is

V=\frac{4}{3} \pi r^{3}

Where r=2.3 m is the radius

The volume of a hemisphere is half the volume of the total sphere:

V_{hemisphere}=\frac{V}{2}=\frac{\frac{4}{3} \pi r^{3}}{2}

V_{hemisphere}=\frac{2}{3} \pi r^{3}

Solving this equation:

V_{hemisphere}=\frac{2}{3} \pi (2.3 m)^{3}

Finally:

V_{hemisphere}=25.48m^{3} \approx 25.5 m^{3}

On the Algebra test the number of students who got a grade A was three more than twice the number of students who got lower grad
svlad2 [7]
X= # students who got lower grades
2x+3= # students with grade A

STEP 1:
Add the two sets above equal to 24.

x + (2x + 3)= 24
combine like terms

3x + 3= 24
subtract 3 from both sides

3x= 21
divide both sides by 3

x= 7 (# students lower than A)


STEP 2:
substitute x value from step 1 to find # grade A students

=2x + 3
=2(7) + 3
=14 + 3
=17 (# grade A students)


CHECK:
x + (2x + 3)= 24
7 + 2(7) + 3= 24
7 + 14 + 3= 24
24= 24


ANSWER: There were 17 students with grade A.

Hope this helps! :)

2x - 6 = 0 and 2y = 10. Find 3^x/3^y.
pshichka [43]

Answer:

\dfrac{1}{9}

Step-by-step explanation:

2x - 6 = 0

\implies 2x = 6

\implies x=3

2y = 10

\implies y=5

\dfrac{3^x}{3^y}=\dfrac{3^3}{3^5}=\dfrac{1}{3^2}=\dfrac{1}{9}
