Just flip them around: -2 -2 -5 3 8
Answer:
35 degrees
Step-by-step explanation:
The angles in a triangle and a straight line add up to 180 degrees.
So adding the angles together:
BCD + BCA = 180
75 + BCA = 180
BCA = 115
Then,
BCA + BAC + ABC = 180
115 + 40 + ABC = 180
Therefore,
ABC = 35 degrees
Answer:
-10.2n - 1
Step-by-step explanation:
−2.4n − 3 + (−7.8n + 2) =
= -2.4n - 7.8n - 3 + 2
= -10.2n - 1
Answer:
15
Step-by-step explanation:
let r represent red marbles then white = 2r + 5 and total is 20, thus
r + 2r + 5 = 20 ( subtract 5 from both sides )
3r = 15 ( divide both sides by 3 )
r = 5 ← number of red marbles
Thus number of white = 20 - 5 = 15
Answer:
73155
Step-by-step explanation:
Step 1: Add the first 2 digits in the number
Step 2: Subtract digit 3 from Digit 2
Step 3: Multiply Digit 3 and 4
Step 4: Divide Digit 4 by 3
The next number is:
1 + 6 = 7
6 – 3 = 3
3 * 5 = 15
5 / 1 = 5
Thus; the number is 73155
