Answer:

$\Large \boxed{x=1}$

Step-by-step explanation:

Substitute m=(2x+1) and n=(6) in m+n=(9).

We are finding the value of the x variable.

$2x+1+6=9$

Add the numbers on the left side of the equation.

$2x+7=9$

Subtract 7 from both sides.

$2x+7-7=9-7$

$2x=2$

Divide both sides by 2.

$\displaystyle \frac{2x}{2}=\frac{2}{2}$

$x=1$

The value of the x variable is 1.

Answer:

x equals 3.00cm

Step-by-step explanation:

Use Pythagoras' Theorem.

a = (14x-45)

b = (16x+27)

c = (25x)

Plug in the variables above into Pythagoras' Theorem that is, a^2+b^2=c^2.

Solve the resulting quadratic equation and reject the negative answer as length is always positive.

$\\
\text{Michael distrinutes 2345 packages of screws into 5 equal groups for shipping.}\\
\\
\text{we need to find the number of packages of screws in each group.}\\
\\
\text{so for this we use the unitary method.}\\
\\
\text{The number of packages of screws in 5 groups}=2345\\
\\
\text{so the number of packages of screws in 1 group}=\frac{2345}{5}\\
