2m=p-q/r solve for r

Mathematics
1 answer:
Oduvanchick [21]4 years ago
6 0

To solve for r, you would start by subtracting p from both sides.

2m - p = -q/r

Multiply everything by r.

2mr - pr = -q

Factor r out of the left side of the equation.

r(2m - p) = -q

Divide both sides by (2m - p).

r = \frac{-q}{2m-p} = \frac{q}{2m + p}.

Solve the formula for x<br>Gx +Hy=J​
ra1l [238]

Answer:

x = \frac{J-Hy}{G}

Step-by-step explanation:

This question is from the topic subject of formula. It implies expressing x in terms of G, H y and J.

Given that: Gx + Hy = J

Subtract Hy from both sides to have;

Gx + Hy - Hy = J - Hy

⇒  Gx = J - Hy

Then divide both sides by G, so that we have;

x = \frac{J-Hy}{G}

Therefore,

x = \frac{J-Hy}{G}

Write an Equation using the following arithmetic sequence: 5, _____, ______, 32
Shalnov [3]

Answer:

The sequence is:

5, 14, 23, 32

Step-by-step explanation:

We know that an Arithmetic sequence with a₁ and the commo difference 'd' has the nth term such as:

aₙ = a₁ + (n-1)d

Given the arithmetic sequence

5, _____, ______, 32

here:

a₁ = 5

n = 4

aₙ

so substituting a₁ = 5, n = 4 and aₙ = 32 in the nth term

aₙ = a₁ + (n-1)d

32 = 5 + (4-1)d

32 = 5 + 3d

3d = 32-5

3d = 27

divide both sides by 3

3d/3 = 27/3

d = 9

Therefore, the common difference: d = 9

Determining the 2nd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 2, a₁ = 5, d = 9

a₂ = 5 + (2-1)9

a₂ = 5 + 1(9)

a₂ = 5 + 9

a₂ = 14

Determining the 3rd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 3, a₁ = 5, d = 9

a₃ = 5 + (3-1)9

a₃ = 5 + 2(9)

a₃ = 5 + 18

a₃ = 23

Thus, the sequence becomes:

5, 14, 23, 32
