-(2x+5)=-10-2x plz help

Scilla [17]

−(2x+5)=−10−2x

Step 1: Simplify both sides of the equation.

−(2x+5)=−10−2x

−2x+−5=−10+−2x(Distribute)

−2x−5=−2x−10

Step 2: Add 2x to both sides.

−2x−5+2x=−2x−10+2x

−5=−10

Step 3: Add 5 to both sides.

−5+5=−10+5

0=−5

There are no solutions.

Bert earns $35,000 gross annual salary. In Bert's jurisdiction there is a progressive tax system with rules as follows: Any amou

Bogdan [553]

Answer:

7.5

Step-by-step explanation:

Given;

Bert earns $35,000 gross annual salary
Any amounts earned up to $20,000 are taxed at x%
Any amounts earned beyond $20,000 are taxed at 20%
Bert pays $4,500 per annum in income tax

To find x

Amount earned beyond $20,000

= $35,000 - $20,000

= $15,000

That is the amount to be taxed at 20%

Therefore,

x% × 20000 + 20% × 15000 = 4500

200x + 3000 = 4500

200x = 4500 - 3000

200x = 1500

x = 1500/200

x = 7.5

A diagonal of a cube measures StartRoot 294 EndRoot cm. The diagonal of a face measures 14 cm. What is the length of an edge of

hram777 [196]

The side of the edge of the cube is 9. 9cm

<h3>How to determine the length</h3>

Given that the diagonal of a cube measures the square root of 294cm and the diagonal of a face measures 14cm

To find the edge of the face, we know that the face of the cube is a square

Formula for diagonal of a square = $\sqrt{2a}$

Where is the side of the square

We then have,

$\sqrt{2a} = 14$

Make 'a' the subject

a = $\frac{14}{\sqrt{2} }$

Simplify the surd

a = $\frac{14}{\sqrt{2} }$ × $\frac{14}{\sqrt{2} }$

a = $\frac{14\sqrt{2} }{2}$

a = $7\sqrt{2}$

a = 9. 9cm

Therefore, the side of the edge of the cube is 9. 9cm
