Answer:
x = 2/3
Step-by-step explanation:
x − 5(x − 1) = x − 2x + 3
−5 (x − 1) = −2x + 3
−5x + 5 = −2x + 3
5 = −2x + 3 + 5x
5 = 3x + 3
5 − 3 = 3x
2 = 3x
2/3 = x
x = 2/3
Answer:
5/4
Step-by-step explanation:
To divide 10/12 by 4/6, invert the divisor (4/6) and multiply the result:
10 6
------- * ------ = 10/8 = 5/4
12 4
Answer: 8 chess matches and 11 cribbage matches.
Step-by-step explanation:
60 people, 4 people play a match of cribbage, so if theres 3 more matched than chess we can subtract that from the total 60 to get the answer. 3x4=12 60-12=48, 2 people per chess game and 4 people per cribbage game add them 6, 48 divided by 6 since its an even amount now, 48/6=8 add 8 matched to the remaining 3 for the cribbage.
A triangles angles measure up to 180° so before finding x you must find the missing angle.
So lets make an equation:
180=22+23+a
(a is the missing angle)
So add 22+23=45
180=45+a
Subtract 45 from both sides to isolate A
180-45=45-45+a
135=a
135° is your missing angle
So now we have to find X
A straight line measures to 180° so now we subtract 135°(or a) from 180°
180-135=x
x=45
Therefore X is 45°
