If you estimate
7 times 7=49 so the square root of 46 is less than 7
6 times 6= 36 so the square root of 46 is more than 6
so if you do it on a calculator the answer is 6.78
The answer is D: 2x 15/4 y 17/4
Answer:
7/6 or 1 1/6
Step-by-step explanation:
First convert 2 1/3 into just a normal fraction
2 1/3 = 7/3
Next set up the equation and multiply from left to right on both the top and bottom.
1/2 x 7/3 = 7/6
1 x 7 = 7
2 x 3 = 6
Answer: 7/6 or 1 1/6
Answer:
There are 13 motorcycles and 22 cars
Step-by-step explanation:
Let x represent the number of motorcycles, and let y represent the number of cars. We can set up a system of equations to solve this...
x + y = 35 (there are a total of 35 vehicles)
2x + 4y = 114 (the total number of tires)
Solve the first equation for either variable...
y = 35 - x
Now substitute that value into the other equation and solve...
2x + 4(35 - x) = 114 (y becomes 35 - x)
Now solve...
2x + 140 - 4x = 114
-2x = -26
x = 13 (there are 13 motorcycles)
Now plug that value into either original equation to solve for y...
13 + y = 35
y = 22 (there are 22 cars(
