Answer:
see explanation
Step-by-step explanation:
(5)
Since ∠EBA = 90° then ∠ABD = 90° ( straight angle ) and
∠ABC + ∠CBD = ∠ABD, that is
2x + 3x - 10 = 90, simplifying
5x - 10 = 90 ( add 10 to both sides )
5x = 100 ( divide both sides by 5 )
x = 20, thus
∠ABC = 2x = 2 × 20 = 40°
∠CBD = 3x - 10 = (3 × 20) - 10 = 60 - 10 = 50°
(6)
4x - 18 = 3x + 7 ( vertical angles are congruent )
Subtract 3x from both sides
x - 18 = 7 ( add 18 to both sides )
x = 25
7y = 5y + 28 ( vertical angles are congruent )
Subtract 5y from both sides
2y = 28 ( divide both sides by 2 )
y = 14
I think u just connect the dots
Answer:
Step-by-step explanation:
we have
Distribute in both sides
Combine like terms in both sides
group terms that contain the same variable
Adds 9x both sides
Subtract 26 both sides
Divide by 4 both sides
The correct graph of these two inequalities is shown below.
Answer:
D.
Step-by-step explanation:
This will be D because the beaker already has 0.2 mL of water. If Jovita needs to add more water to the beaker, and<em> then </em>it is 0.8. In D, the diagram shows you 0.2 + x = 0.8, which makes it the right diagram.
Hope that helps!
