Answer:
x = 6/5 = 1 
Step-by-step explanation:
3x + 1 = -2x + 7
+2x - 1 = + 2x - 1
5x = 6
x = 6/5 = 1 
Hope this helps:)
Answer:
D
Step-by-step explanation:
First, let's find <em>x</em>.
We know that one of the angles is 30. The side opposite to than angle is 11, and <em>x</em> is the adjacent side to it. Therefore, we can use the trig function tangent.
Recall that:

Plug in 30 for the angle, 11 for the opposite, and <em>x</em> for the adjacent. Solve for <em>x</em> by cross-multiplying:

From the unit circle, recall that tan(30) is equal to one over the square root of 3. Thus:

Now, we can use the Pythagorean Theorem to find <em>y</em>. <em>y</em> is the hypotenuse. Thus:

Answer:
t - 2 ≥ 7; t ≥ 9
Explanation:
“a number t” = t
“decreased by 2” = - 2
“Is at least 7” = ≥ 7
So, t - 2 ≥ 7
To solve for t - 2 ≥ 7, add 2 to both sides of the equation
t - 2 ≥ 7
t - 2 + 2 ≥ 7 + 2
t ≥ 9
So, t ≥ 9
Answer:
z
Step-by-step explanation:
coordinate should be put as (1,2). Plot it and you will get z as answer
Answer:
C 117
Step-by-step explanation:
<2 = 63 vertical angles
<2 = <4 alternate interior angles
<4 + <7 = 180 straight line
63 +<7 = 180
subtract 64 from each side
<7 = 180-63
<7 = 117
