Answer:
6x + 1
Step-by-step explanation:
1. (10x + 3) + (-4x -2) --> sum means to add.
2. Combine like terms --> 10x - 4x = 6x; 3 - 2 = 1.
3. 6x + 1
Answer:
x = 71
Step-by-step explanation:
The chord- chord angle is half the sum of the arcs intercepted by the angle and its vertical angle, that is
x = 
(92 + 50) = 0.5 × 142 = 71
Answer:
2x-y=-1
Step-by-step explanation:
y + 9 = 2(x + 5)
y + 9 = 2x + 10 [distribute]
y = 2x + 1 [subtract 9 from both sides]
y - 2x = 1 [subtract 2x from both sides]
-2x + y = 1 [put x first]
2x - y = -1 [multiply by -1 to make x coefficient positive]
The missing dimension, x, is 7.5.
if you take 45 and divide it by 6 you can get the next dimension needed to get the full number, 45. You can also find it by dividing 35 and 4. I hope this helps.
45.
12/18 = 8/x <=> 2/3 = 8/x <=> x = (3*8)/2 = 12;
