Step-by-step explanation:
Find the diameter.
D=9.2-2.5-2.5=4.2
Radius = d/2
r=4.2/2=2.1
Area = πr^2
A=π(2.1)^2=13.8
Answer:
No, this equation cannot be solved.
Step-by-step explanation:
Let's try to solve it.
12x + 10 = 4( 3x + 3 ) Use distributive property
12x + 10 = 12x + 12 Isolate variables from constants (have no variables)
12x + 10 - 10 = 12x + 12 - 10 Subtract 10 form both sides
12x = 12x + 2 Subtract 12x from both sides
12x - 12x = 12x - 12x + 2
0 = 2 Impossible
This statement is false. Therefore, this equation cannot be solved.
*If you've learned linear graphs, this idea may help you:
The expressions on each side are 12x + 10 and 12x + 12 (after expanded).
A linear graph is y = mx + b, where "m" represents the slope. If two lines have the same slope, they will never meet, and cannot be solved. In this case, "m" is 12 for both of them.
The number is 157, because it's 100-200, 10-5=5 (ones place) & 5+2=7 (tenths place)
