Answer:
$30
Step-by-step explanation:
Dollars : Pesos
250 : 4250
X : 510
250/4250 = X/510
X = 30
Answer: Rounded to the nearest tenths place, it is 3.7 meters.
Step-by-step explanation:
Using the above formula, let's multiply 2.5 times 2.5 and 4.5 times 4.5.
2.5 times 2.5, or 2.5 squared, equals 6.25
4.5 times 4.5, or 4.5 squared, equals 20.25
Now, let's subtract 20.25 minus 6.25. The difference is 14.00.
What is the square root of 14? It is 3.74165739. Let's round that number to the nearest tenths place.
What is the number in the tenths place? It is 7. And--what is the number that comes after it? Well, it is 4. Therefore, the 7 should stay a seven. If the number next to the tenths place was five or greater, then we should add one.
Answer: tables cost $8 each and chairs cost $2.5 each.
Step-by-step explanation: Let c be for chairs and t be for tables...
2c + 5t = 45
8c + 3t = 44
To find t, multiply the first equation by -4 so that we can use the process of elimination:
-8c - 20t = -180
+ 8c + 3t = 44
-17t = -136 or t = 8
To find c, plug t into the original equation:
2c + 5(8) = 45
2c + 40 = 45
2c = 5
c = 2.5
how to solve this problem the answer is -555498
The perpendicular line of x=4 should be whatever the value of y is in the given point, that means y=5
