Answer:
infinitely many solutions
Step-by-step explanation:
1) distribute 9 to each term inside parenthesis on left side of equation
18x+90=2(9x+45)
2)now distribute 2
18x+90=18x+90
these equations are exactly the same! this means that this equation has infinitely many solutions
Hope this helps!
Well, to know right away whether or not a number is equal to 1, you need to know what 1 is in scientific notation. 1 * 10^0. Easy enough :) To know if the number is greater than one, any positive number multiplied by 10^a number higher than 0 is greater than one. As well as any number greater than one multiplied by 10^0 or a positive number. For numbers less than one, the way to know is if the number is being multiplied by 10 ^ a negative number. I hope this helps :)
Dividing a number by the ratio 3:2 means dividing into 3+2 = 5 parts
Let (0, 0) be (x₁, y₁) and (3, 6) be (x₂, y₂)
Find one part of the share for each axes, we do


Then multiplying the one part back into 3: 2, we have
for the x - axis ⇒ (3×0.6) : (2×0.6) = 1.8: 1.2
for the y - axis ⇒ (3×1.2) : (2×1.2) = 3.6: 2.4
The coordinate that divides the segment into 3 parts and 2 parts is (1.8, 3.6)
Correct answer: A

45+ 70x=150
the answer is 1.5 so an hour and a half
