Answer:
a) x = 6° b) m∠B = 50°
Explanation:
(a) total angle measure of a triangle is 180°
8x + 2 + 70° + 60° = 180°
8x + 132° = 180°
8x = 180° - 132°
8x = 48°
x = 6°
(b)
m∠B = 8x + 2
m∠B = 8(6) + 2°
m∠B = 48° + 2°
m∠B = 50°
Hi there!
To solve this problem, we need to divide the total amount of tables by the amount of students:
40 / 10 = 4
So, we need 4 tables to seat 40 students.
Hope this helps!

Answer:
(2, 3 )
Step-by-step explanation:
Given the 2 equations
x - 2y = - 4 → (1)
2x + y = 7 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
4x + 2y = 14 → (3)
Add (1) and (3) term by term to eliminate y, that is
5x = 10 ( divide both sides by 5 )
x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (2)
2(2) + y = 7
4 + y = 7 ( subtract 4 from both sides )
y = 3
Solution is (2, 3 )
