What is the solution set for [-x]=10

1 answer:

6 0

X = -10

Because it is the "absolute value" of "10"

Here's why

-X - 10 = 0, right ?

So, now we have to add a positive 10 to each of our sides to get one step closer to our answer

-X + 10 = 0 ⬅️cancel this
0 + 10 = 10 ⬅️keep this

We can multiply by a negative 1 (-1 )

10(-1) = -10
0(-1) = -0

So that's how we found out that X = -10

Answer:

Sarah spent 45.76

Jack spent 38.16

Jack spent more on tax

Step-by-step explanation:

Sarahs game costs:

tax = 44 *.04 = 1.76

Total cost = game + tax

= 44 + 1.76

=45.76

Jacks game costs:

tax = 36 *.06 = 2.16

Total cost = game + tax

= 36 + 2.16

=38.16

Jack spent more on tax

Answer:

∠NQP = 74°

Step-by-step explanation:

NPQ is a triangle.

We know the sum of 3 angles of a triangle is 180 degrees. So we can write:

N + P + Q = 180

2x + 34 + 2x + 2 = 180

Now, we can solve for x:

$2x + 34 + 2x + 2 = 180\\4x+36=180\\4x=180-36\\4x=144\\x=\frac{144}{4}\\x=36$

The measure of NQP is "2x+2", we plug in x = 36, and find the measure of NQP:

∠NQP = 2(36) + 2 = 74°
