Answer:

125

Step-by-step explanation:

A.) We paid $400 on props for a school play. We have made a profit of $100 by charging $4 for one admission.

B.) Variable P for people

C.) -400 + (P*4)= 100

D.) -400+(P*4)=100

+400 +400

P*4=500

/4 /4

P=125

Solve the system by substitution -x-y-z=-8 -4x+4y+5z=7 2x+2z=4 show the work

Bezzdna [24]

ANSWER 

$x=3,y=6,z=-1$

EXPLANATION

We the have the equations,

$-x-y-z=-8$

Multiplying through by negative one gives,

$x+y+z=8---(1)$

Also

$-4x+4y+5z=7---(2)$

and

$2x+2z=4$

Dividing through by 2 gives

$x+z=2$

Making z the subject gives,

$z=2-x---(3)$

Now we substitute equation (3) into equation (1) and (2)

Equation (3) in to equation (1) gives,

$x+y+2-x=8$

This implies that;

$y=8-2$

$y=6$

We now put equation (3) in (2) to get,

$-4x+4y+5(2-x)=7$

This implies that

$-4x+4y+10-5x=7$

$-9x+4y=7-10$

$-9x+4y=-3$

But

$y=6$

So,

$-9x+4(6)=-3$

$-9x+24=-3$

$-9x=-3-24$

$-9x=-27$

Dividing through by negative 9 gives

$x=3$

and

$z=2-3$

$z=-1$

Therefore $x=3,y=6,z=-1$

Use the formula to find the value of the indicated variable for the values given.

Whitepunk [10]

Answer:

A = 3,649

Step-by-step explanation:

If the formula that we have to use is A = bh, then let's substitute the variables with the given values.

The completely substituted equation is A = (89)(41).

Multiply 89 by 41 to figure out what A is, which is 3,649.

The total source voltage in the circuit is 6-3i V. What is the voltage at the middle source

Bezzdna [24]

Answer:

The voltage at the middle source is $(2-4\mathbf{i})\ V$

Step-by-step explanation:

Voltage Sources in Series

When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.

The figure shown has three voltage sources of values:

$2 + 6\mathbf{i}$

$a + b\mathbf{i}$

$2 - 5\mathbf{i}$

The sum of these voltages is:

$V_t=4+a+(6+b-5)\mathbf{i}$

Operating:

$V_t=4+a+(1+b)\mathbf{i}$

We know the total voltage is $6-3\mathbf{i}$ , thus:

$4+a+(1+b)\mathbf{i}=6-3\mathbf{i}$

Equating the real parts and the imaginary parts independently:

4+a=6

1+b=-3

Solving each equation:

a = 2

b = -4

The voltage at the middle source is $(2-4\mathbf{i})\ V$
