Answer: 52

Step-by-step explanation:

The two angles on the base in the triangle is 17 and 111 as the angles of straight line have to be 180 so 2x = 180 - 111 - 17 as the sum of all the angles in the triangle have to be 180

x = 52

Help? 5/12 + 5/8 (spam cause i need 20 characters)

Jobisdone [24]

Answer:

1 1/24

Step-by-step explanation:

5/12 + 5/8

We need a common denominator of 24

Convert the first number to have a denominator of 24

5/12 *2/2 = 10/24

Convert the second number to have a denominator of 24

5/8*3/3 = 15/24

Add the two converted numbers together

10/24 + 15/24

25/24

Change from an improper fraction to a mixed number

24/24 + 1/24

1 1/24

The equation 3x + 6 = 12 involves two operations performed on x: multiplication by 3 followed by addition of 6. What operations

BlackZzzverrR [31]

3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)

3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6

$\frac{3x}{3}$ = $\frac{6}{3}$
3 and 3 cancels out
x = 2
