Answer:
2x + 5y = -4
Step-by-step explanation:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
Answer: 62+63+64
Step-by-step explanation:
Divide 189 by 2. That gives you 63. Then go for a number 1 above it and 1 below it.
Answer:
3k^2 -k+5
reason:
when adding two equations together, you combine like terms.
First, add -2 to 7 to get 5
Then, add k, or 1k, to -2k, which gives you -1k, or just -k
3k^2 stays the same because there are no like terms in the other equation to combine it with
Answer:
The answer to your question is 5/4 or 1 1/4
Step-by-step explanation:
Data
distance traveled from home to the lake = 1 9/12
total distance = 4 9/12
distance traveled around the lake = ?
Process
1.- Convert the mixed fractions to improper fractions
a) 1 9/12 = (12 + 9)/12 = 21/12 = 7/4
b) 4 9/12 = (48 + 9)/ 12 = 57/12 = 19/4
2.- Multiply the distance from home to the lake by two
7/4 x 2 = 14/4 = 7/2
3.- Subtract the result of "2" from the total distance
19/4 - 7/2 = 19/4 - 14/4 = 5/4
5.- The distance around the lake is 5/4 or 1 1/4
