Answer:
1/2
Step-by-step explanation:
2 1/4 - 1 3/4 Because the denominator are already the same, all you have to do is make it a mixed number and subtract. To do that you multiply the whole number to the denominator and add that new number to the numerator. So you would then have.
9/4 - 7/4
Keep the denumerator the same and subtract the numerators.
2/4
Then simplify
1/2
Answer:
68.5
Step-by-step explanation:
Angles DEC and DAC are right angles, so their sum is 180°. DECA is a quadrilateral, which has a sum of interior angles equal to 360°. Then angle ACE is the supplement of angle D:
∠ACE = 180° -43° = 137°
Inscribed angle ABE has half the measure of central angle ACE, so we have ...
x° = 137°/2
x = 68.5

Answer:
-2a + 4b - 3c.
Step-by-step explanation:
(2a+3b-c) - (4a-b+2c)
Distribute the negative over the second parentheses.
= 2a + 3b - c - 4a + b - 2c
= -2a + 4b - 3c.
