I believe the answer is c
9x + 8 = 2
Subtract 8 from both sides:
9x = -6
x = -6/9
Simplify:
x = -2/3
Answer: C. ∠SQP and ∠TQR
Step-by-step explanation:
Since, by the given diagram,
m∠TQR = m∠SQP (vertical angles)
And, m∠TQP < m∠TQR
By adding ∠TQR on both sides,
m∠TQP + m∠TQR < m∠TQR+m∠TQR
⇒m∠TQP + m∠TQR < 2 ∠TQR
⇒ 180° < 2 m∠TQR ( Because ∠TQP and ∠TQR are linear angles)
⇒ 90° < m∠TQR
Hence ∠TQR is a obtuse angle,
⇒ ∠SQP also is a obtuse angle.
Answer:
a = 3
Step-by-step explanation:
Here you can use the cross multiplication strategy or whatever it's called. That's where you multiply the diagonals together. Its kinda long to explain, but you can google it for details.
In either case, you get the following equation:
8(2a-1) = 4(a+7)
Open the parenthesis
16a - 8 = 4a + 28
Subtract 4a from both sides
12a - 8 = 28
Add 8 to both sides
12a = 36
Divide both sides by 12
a = 3
Sorry for weird formatting I'm on an ipad.
