Given:

Selling price of a machine = 7000/-

Gross loss = 20%.

To find:

The cost and gross loss.

Solution:

Let x be the cost of machine.

According to the question,

x-20\%\text{ of }x=7000

x-\dfrac{20}{100}x=7000

x-0.2x=7000

0.8x=7000

Divide both sides by 0.8.

x=\dfrac{7000}{0.8}

x=8750

So, the cost of the machine is 8750/-.

Now,

\text{Gross Loss}=\text{Cost}-\text{Selling price}

\text{Gross Loss}=8750-7000

\text{Gross Loss}=1750

Therefore, the gross loss is 1750/-.

The only solution is x=7
Although the problem is solves correctly, always makes sure to check it by inputting it back into the equation. Putting -3 into the equation, one side turns negative and the other is positive. For this reason, it is impossible for one of the answers to be -3.

25x-2+3(x-4)

25x-2+3x-12
-3x on both sides

22x-2=-12
+2 on both sides

22x= -10
Divide by 22 both sides

-10/22

Then you simply giving you

- 22 - 7v = - 3(8V + 4)<br> Round to the nearest hundreth
Dmitriy789 [7]

Answer:

v = 0.58

Step-by-step explanation:

-22 - 7v = -3(8v + 4)

Expand -3(8v + 4)

3 * 8v - 3 * 4

Simplify -3 * 8v -3 * 4

= -24v - 12

-22 - 7v = -24v - 12

Add 22 to both sides

-7v = -24v +10

Add 24v to both sides

17v = 10

\frac{17v}{17} =\frac{10}{17}

v =\frac{10}{17}

v=0.58

How do you solve this? If you can answer on paper
ser-zykov [4K]

Answer:

∠?=40°

Step-by-step explanation:

Remember that in a line AND a triangle there are <u>180 degree</u>s.

You correctly found the third angle in the left triangle to be 69°, Now plug it into the equation for a line, including 71°:

<u>69°+71°+x=180°</u>

1) Combine the degrees:

140°+x=180°

2) Subtract 140° from both sides:

x=40°

We have now found the bottom left angle for the triangle on the right to be 40°

To find the angle labeled "?" You must plug in all of the known angles of the triangle to be equal to 180°:

40°+100°+x=180°

1) Combine the degrees:

140°+x=180°

2) Subtract 140 from both sides:

∠?=40°

The formula that is useful for solving both of these problems is ...

(v_2)^2-(v_1)^2=2ad\qquad\text{a=acceleration, d=distance}\\\\ \text{where $v_1$ and $v_2$ are initial and final velocities}

9. Given v₁=15, a=9.8, d=10, find v₂.

... (v₂)² = 15² + 2·9.8·10

... v₂ = √421 ≈ 20.5 . . . . m/s

10. Given d=12 m when a=-9.8 m/s² and v₂=0, find d when a=0.17·(-9.8 m/s²).

The formula tells us that d=(v₁)²/(2a), which is to say that the distance is inversely proportional to the acceleration. If acceleration is 0.17 times that on earth, distance will be 1/0.17 ≈ 5.88 times that on earth.

(12 m)/0.17 ≈ 70.6 m
