Answer:
3x+y=8 and 3x+y=9
Step-by-step explanation:
Assume these two equations:
a1x+b1y+c1=0
a2x+b2y+c2=0
If (a1/a2) = (b1/b2) ≠ (c1/c2) than those two would have no solution.
In these case, take a look at the last option:
Re-write 'em as a standard form:
So (a1/a2) = (b1/b2) ≠ (c1/c2) is true here:
And they do not have any collision point
Answer:
15 ounces
Step-by-step explanation:
6/40 = 0.15
0.15 x 100 = 15
15 ounces
5/7 ÷ 1/3 = 5/7 × 3/1 = 15/7
Answer:
x = 7
Step-by-step explanation:
The property of a parallelogram is the opposite sides are congruent, hence
AD = BC ← substitute values
5x + 3 = 38 ( subtract 3 from both sides )
5x = 35 ( divide both sides by 5 )
x = 7
Answer:
211 / 41 = 5 hours
Step-by-step explanation:
the total was 211 dollars, so you can add 25 dollars and 16 dollars together. That gives us 41 dollars. 211 divided by 41 is approximately 5 hours.
Hope it helps!
