Are you supposed to estimate or get an exact answer? If you're estimating you can see if the number is close to any perfect squares. In this case 63 is very close to 64, and 48 is very close to 49. The answers can then be estimated to be approximately 8 and 7, respectively.
Answer:
D. Infinite solutions
Step-by-step explanation:
Any solution where a number equals itself represents infinite amount of solutions.
The best unit measurement to measure the distance across Lake Erie is kilometers in metric and miles in English.
Yes, you just times one of the equations by a numberr to make it cancel out with the other. For instance:
2x + 6 y = 10
4x + 2y = 16
If we multiply the equation 2x + 6 y = 10 by 2 we get the following
2x + 6 y = 10
-2(2x + 6 y) = -2(10)
-4x -12y = -20
Now we use this new equation.
-4x -12y = -20
4x + 2y = 16
As you can see, you can cancel out the x and solve for y now.
Answer:
The product of two numbers is negative. Which statement is true? Select TWO answers.
A. The quotient of the two numbers is positive.
B. The quotient of the two numbers is negative.
C. No conclusion can be drawn about the quotient.
D. The signs of both numbers are negative.
E. The sign of one number is positive and the sign of the other is negative.
Step-by-step explanation:
The correct two options are B (the quotient of the two number is negative) and E (the sign of one number is positive and the sign of the other is negative).
To validate Option B; quotient is the result we get when we divide two numbers. For instance: 
To validate Option E; multiplying two number of opposite sign will give us negative sign. For instance:
