Step-by-step explanation:
let the cost of the bench = x
the cost of the garden table = x + 82
x + (x + 82) = 668
2x + 82 = 668
2x = 586
x = 293
The bench costs $293 and the garden table costs 293 + 82 = $375
can you mark me as brainliest, it will help me a lot. thank you in advance
X is the number of tasks shelly acomplished and the whole explression (90x) is the total number of points she earned.
Answer:
Hope it helped,
Happy homework/ study/ exam!
Answer:
c.10x90
Step-by-step explanation:
if you multiply 10 by 90 it will give you 900. i learned math a weird way. i think this only works with 10's. if you take 1 and 9 and multiply them you will get 9. then there are two zeros in total out of 10 and 90 then you add them to the 9 to get 900
Answer:
multiply all the numbers

Answer:
314 cm²
Step-by-step explanation:
It's not the point O, but the circle O, a point has no area.
The area of a circle is given by the formula A = π r²
We don't have r (radius), but we have the diameter, which is double the radius. So, r = d / 2 = 20 cm / 2 = 10 cm
Now, we can plug r directly into the equation:
A = π r² = π 10² = 100π = 314 cm²
