Answer:

I think these are the right answers. The answer to one is 32. The answer to two is 38.

1: 2[18-(5+3^2)/7]

2[18-(5+9)/7]

2[18-14/7]

2[18-2]

2 times 16 = 32

2: I used a calculator for this one.

Solve the rational equation. If an equation has no solution, so state.<br>x+6/x=-7​
kupik [55]

Answer:

x=−1 or x=−6

Step-by-step explanation:

Multiply all terms by x and cancel:

xx+6=−7x

x2+6=−7x(Simplify both sides of the equation)

x2+6−−7x=−7x−−7x(Subtract -7x from both sides)

x2+7x+6=0

(x+1)(x+6)=0(Factor left side of equation)

x+1=0 or x+6=0(Set factors equal to 0)

x=−1 or x=−6

Check answers. (Plug them in to make sure they work.)

x=−1(Works in original equation)

x=−6(Works in original equation)

a circuit overloads at 1800 watts of electricity you plug a microwave oven that uses 1100 watts into the circuit write and solve
Bogdan [553]
Let w be the additional watts you can add on the circuit.

1100 + w < 1800 (write the inequality)
-1100 -1100 ( - 1100 from each side)

w < 700 (simplify)


ANSWER:
You can add up to 700 watts to the circuit, which means that you can also plug in the clock radio and the blender.


LOOK BACK:
You can check that your answer is correct by adding the numbers of watts used by the microwave oven, clock radio and blender.

1100 + 50 + 300 = 1450

The circuit will not overload because the total wattage is less than 1800 watts.
