Answer:

x = 11

Step-by-step explanation:

3x - 7 = x + 15 ( subtract x from both sides )

2x - 7 = 15 ( add 7 to both sides )

2x = 22 ( divide both sides by 2 )

x = 11

What is mZCAD?<br> O 80°<br> O 20°<br> O 80°<br> O 100°<br> O 110°

denis23 [38]

Answer:

The angle of CAD is 100°.

Step-by-step explanation:

Given that total angles in a triangle is 180° so you will have to find the angle of CAB :

∠CAB + ∠ACB + ∠ABC = 180°

∠CAB + 80° + 20° = 180°

∠CAB + 100° = 180°

∠CAB = 180° - 100°

∠CAB = 80°

Next, you have to subtract it from 180° because straight line have a degree of 180°

∠CAD = 180° - 80°

∠CAD = 100°

What is the solution to the problem expressed to the correct number of significant figures? 15. 11 (142 × 16. 5) = ? A. 2,358 B.

olchik [2.2K]

The solution to the problem expressed 2358.

<h3>What is the meaning of significant figure?</h3>

Significant figure It is defined as the minimum number of digit us needed to express a number in scientific notation.

Therefore we get,

$15.11+(142\times16.5)$

First we have to multiply the given digits as per rule.

$=15.11+2343$

Now we will add both the digits, we get

$=2358.11$

As per given expression, we conclude that the number of significant figure is 4.

So, the answer will be, 2358.

Therefore, the correct option is, 2358.
