3/4x + 3 - 2x = -1/4 + 1/2x + 5
Put in terms of 4 as denominator
3/4x + 12/4 - 8/4x = -1/4 + 2/4x + 20/4
Combine like terms
-5/4x + 12/4 = 2/4x + 19/4
Simplify
12/4 = 7/4x + 19/4
-7/4 = 7/4x
x = -1 :)
Check:
3/4(-1) + 3 - 2(-1) = -1/4 + 1/2(-1) + 5
-3/4 + 3 + 2 = -1/4 - 1/2 + 5
-3/4 + 5 = -3/4 + 5
-3/4 = -3/4 :)
40°
Step-by-step explanation:
∠ACB = ∠DCE ( vertically opposite angle )
Now...
a + 90° + 50° = 180° ( the sum of interior angle of triangle is 180° )
a + 140° = 180°
a = 180° - 140°
a = 40°
hence the value of a is 40°
48 feet
Divide 858 by 18 to get 47.6 > simplify > 48 feet
Answer:
Area=BH Answer is 242
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
If the line are parallel (those are the ones that dont cross) and a third line crosses both the parallel lines, you get the set up shown in your diagram. Which has EIGHT angles in it. But there's only two measures for all eight of these angles. Four of them are all equal to each other (and the other four all equal to each other) And the two numbers add up to 180°
Here 7x + 12 and 12x - 28 are a couple of the angles that are EQUAL TO each other.
7x + 12 = 12x - 28 Solve.
Subtract 7x from both sides.
12 = 5x - 28 add 28 to both sides.
40 = 5x divide by 5 on both sides.
40/5 = x
8 = x
