Answer:
For x=7 and y=9 Caleb and Eva will meet again. That is, Caleb will have made 7 labs and Eva 9 labs.
Step-by-step explanation:
In order to find the number of labs that Caleb and Eva must complete, to meet again at the start, you can use the following equation:
(1)
where x is the number of labs made by Caleb and y the number of labs made by Eva. The equation (1) means that for the specific values of x and y, Caleb and Eva will spend the same amount of minutes on the labs.
Then, you need to find the least integers values of x and y.
First, you solve the equation (1) for y:
(2)
By inspection you can find that the least value of x that makes possible that y is an integer, is 7
In fact, you have:
Hence, for x=7 and y=9 Caleb and Eva will meet again. That is, Caleb will have made 7 labs and Eva 9 labs.
Answer:
0
Step-by-step explanation:
15(8)-10(12)
15*8=120
10*12=120
120-120=0
(5y^2 – 7y+6) + (-4y^2 + 3y+1)
y^2 - 4y + 7
Done.
The degree of an expression in more than one variable is the highest sum of the powers of the variables in the terms.
Expression:
An algebraic expression is a combination of constant and variables connected by the signs of fundamental operations.
ex: 2x+5
Degree of an expression:
The degree of an expression in one variable is the highest exponent of the variable in that expression.
Ex:
2x^6 + x^4 + 5
Highest exponent = 6
so degree = 6
The degree of an expression in more than one variable is the highest sum of the powers of the variables.
Ex:
3x^1y^2 + 5x^3y^2 + 5
Sum of powers of variables = 3+2 = 5
Degree = 5.
