Answer:
x = 110
Step-by-step explanation:
all angles of the triangle MUST add up to 180 degrees.
45 + 65 = 110
180 - 110 = 70
since x is sittling on a 180 degree angle, the sum of 70 and x must equal 180 too
180 - 70 = 110
<span>So, (72)(3/8) = 27, and 72-27 = 45 must go in the second group.</span>
Answer:
Step-by-step explanation:
Given linear inequality:
Solving for
Subtracting both sides by 5.
Dividing both sides by 2.
∴
The graph of the inequality is shown below.
The line is represented by dotted line because the inequality sign is only greater than which means 22.5 is not included in the solution.
Answer:
Below in bold.
Step-by-step explanation:
Let x be George's age and y be Genemy's age.
x/y = 5/7
(x + 4)/ (y + 4) = 3/4
From equation 1, y = 7x/5 = 1.4x so substituting in equation 2 :
(x + 4)/ (1.4x + 4) = 3/4
3(1.4x + 4) = 4(x + 4)
4.2x + 12 = 4x + 16
0.2x = 16 -12 = 4
x = 4/0.2 = 20 = George's age.
So y = 1.4x = 1.4 * 20 = 28 = Genemy's age.
Your answer will be B: 9/7
