Answer:
No solutions
Step-by-step explanation:
4x + 2y = 2
2x + y = 4
we need to evaluate for y is "2x + y = 4" to be able to solve this.
2x + y = 4
2x - 2x + y = 4 - 2x
y = -2x + 4
4x + 2y = 2
4x + 2(-2x + 4) = 2
4x -4x + 8 = 2
8 = 2
NO solutions
Question 3: 3/8 you just need to multiply across in order to get your answer
Multiple 6 with numbers inside paranthesis:
12x - 66 + 15 = 21
add 66 fhen substrack 15 from both sides :
12x = 72 divide both sides with 12:
x = 6
D is the correct answer.
0.25 is rational because it can be represented as a ratio of integers (1/4).
0.45 is rational because it can also be represented as a ratio of integers (9/20).
When you multiply rational numbers, you always end up with a rational number.
0.25*0.45=0.1125 or 1125/10000
