Well, for solving system of equations, we can use either substitution where we plug one equation into the other, or elimination where we combine the equations.

- Using elimination, you would to eliminate one variable from both equations, so you automatically would get one equation with one variable!

Answer:

value if a =

$\frac{5}{4}$

Step-by-step explanation:

here's the solution :-

=》

$\frac{ 2(\sqrt{m}) {}^{3} }{ \sqrt[4]{m} }$

=》

$\frac{2(m {}^{ \frac{1}{2}} ) {}^{3} }{ {m}^{ \frac{1}{4} } }$

=》

$\frac{2 {m}^{ \frac{3}{2} }} { {m}^{ \frac{1}{4} } }$

=》

$2m {}^{ \frac{3}{2} - \frac{1}{4} }$

=》

$2m {}^{ \frac{6 - 1}{4} }$

=》

$2m {}^{ \frac{5}{4} }$

so, a = 5/4

In order to make a service for four 1 3/4 cups of chopped vegetables are needed. Based on this information, determine the amount

Mila [183]

For this case we propose a rule of three according to the data of the statement. To do this, we convert the mixed number into an improper fraction:

$1 \frac {3} {4} = \frac {4 * 1 + 3} {4} = \frac {7} {4}$ cups

4 ----------> $\frac {7} {4}$

10 ----------> x

Where the variable "x" represents the amount of chopped of vegetables needed for 10 people.

$x = \frac {10 * \frac {7} {4}} {4}\\x = \frac {\frac {70} {4}} {4}\\x = \frac {70} {16}\\x = \frac {35} {8}$

This is equivalent to $4 \frac {3} {8}$ cups.

Answer:

$4 \frac {3} {8}$ cups
