Answer:
x < - 10
Step-by-step explanation:
Given
5 - 3x > 35 ( subtract 5 from both sides )
- 3x > 30
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x < - 10 Or - 10 > x

Answer:
(8.5, - 2 )
Step-by-step explanation:
Given the 2 equations
6x + 4y = 43 → (1)
2x - 3y = 23 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the term in x
- 6x + 9y = - 69 → (3)
Add (1) and (3) term by term to eliminate x, that is
13y = - 26 ( divide both sides by 13 )
y = - 2
Substitute y = - 2 in either of the 2 equations and solve for x
Substituting into (1)
6x + 4(- 2) = 43
6x - 8 = 43 ( add 8 to both sides )
6x = 51 ( divide both sides by 6 )
x = 8.5
Solution is (8.5, - 2 )
Answer:
32.8
Step-by-step explanation:
Since the angles given are 90 degrees and 57.2 you can add those together then subtract them from 180 to find the answer 32.8.
180 - 90 + 57.2 = 32.8
