Answer:
The most simple method for solving systems of equations is to transform one of the equations so it allows for the canceling out of a variable. In this case, we can multiply \displaystyle 3x + y = 8 by to get . Then, we can add \displaystyle 2x + 4y = 12 to this equation to yield , so .
Step-by-step explanation:
Answer:
10x^2 (x+2) (x+6)
Step-by-step explanation:
assuming you meant 120 not 1120
10x^4+ 80x^3 + 120x^2
factor out 10 x^2
10x^2 (x^2 +8x+12)
what numbers multiply together to get 12 and add together to get 8
2*6 = 12 2+6 = 8
10x^2 (x+2) (x+6)
B and D are the same answer?????
0.3km=300m
300m:500m
(/100)
3:5
3+5=8
0.3km= 3/8
500m= 5/8
1.) set up a w_k_u chart
2.) in the w column write in on top and mi in the bottom like this
w_K_U
in_
mi_
then in the k column write 2 for in and 15 for mi
W_K_U
in_2_
mi_15_
then in the U column, you write 7 for in and x for mi
W_K_U
in_2_7
mi_15_x
then cross multiply: 2x = 15(7)
multiply 15 times 7 which is 105
2x=105
divide 2x by 2
x=105
answer 105
