Hi there!

Let's solve this equation step by step!
|x|  - 7 = 6

First add 7 to both sides.
|x|  = 13



Next we need to take a look at the meaning of the stripes between our variable. Those stripes mean we are dealing with an absolute value function. The absolute value stripes make everything between the stripes positive; also when we plug in a number. In this particular question we can plug in both -13 and 13 at the position of n, because when -13 is made positive, it fulfils the equation.

Hence,
x= 13 or x = - 13

~ Hope this helps you!

Hi.

Initial Equation:

| x | - 7 = 6

Add 7 to both the sides of the eqn.

\implies | x | - \cancel{7} + \cancel{7} = 6 + 7

\implies | x | = 13

Hence,

Solution to the equation are \boxed{\sf x = 13} and \boxed{\sf x = -13}

Thanks.

I did the first one I need help on this that’s all
Alenkasestr [34]

Answer:

m<A = 70 deg

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180 deg. Add the three measures and set equal to 180. Solve for x. then use the value of x and the expression for m<A to find the measure of angle A.

m<A + m<B + m<C = 180

5x - 25 + 2x + 10 + 3x + 5 = 180

10x - 10 = 180

10x = 190

x = 19

m<A = 5x - 25 = 5(19) - 25 = 95 - 25 = 70

Answer: m<A = 70 deg
