Do u mean 6x = x squared? if so x is 6
Answer:
Front end estimation is a way of rounding numbers to estimate sums and differences.
Step-by-step explanation:
also if you don't mind giving me brainliest i'm just trying to rank up. only if u dont mind.
We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).
79-74 = 5. So the mean has increased by 5 points. (C)

The total cost of the items was $298.20
We find this by taking the cost of 1 thing like the curtains, then we see how many were brought, which was 3. So we do the cost which is $24.50 and multiply that by 3 to get $73.50. And we keep doing this with the other items and add them up.
Answer:
x = 20°
Step-by-step explanation:
The angle opposite to 3x + 20 is also 3x + 20 (opposite interior angles)
The angle opposite to 5x is also 5x (opposite interior angles)
Solve:
Set up the equation by adding all the angles. The sum of these angles should equal 360.
- (3x + 20) + (3x + 20) + (5x) + (5x) = 360
- 16x + 40 = 360
- 16x = 320
- x = 20
x = 20°
