Answer:
where is the rest of the questions
Step-by-step explanation:
I guess, it means every meter costs these amounts.
and the specified costs are not fit the whole bundle.
it is also unclear, if "half of it" means half of the original x meters, or half of the remaining meters (after selling 2/5 of the original meters). I assume the first.
so, we have
-5x
+ 2/5x × 5.5
+ 1/2x × 6.4
+ (10/10 - 4/10 - 5/10)x × 6 = + 1/10x × 6
= 120 ( a income minus costs is the profit, so balancing both sides in a "+" and "-" expression gives us the remaining profit).
about the line with the 1/10 :
the leftovers. 10/10 is the whole x at the beginning.
2/5 = 4/10.
1/2 = 5/10.
I brought all involved fractions to the same denominator of the smallest common multiple of 2 and 5 (10).
in full
-5x + (2/5)x×5.5 + (1/2)x×6.4 + (1/10)x×6 = 120
-5x + 2.2x + 3.2x + 0.6x = 120
-5x + 6x = 120
x = 120
so, he bought 120m in the first place.
it is a bracket used in maths
Hi there!
simplest ratio form: 2:1
<em><u>1.Find commonest denominator:</u></em>
<em><u /></em>
<em><u /></em>
<em><u>2.Divide both with the term:</u></em>
<em><u /></em>
<em><u /></em>
Therefore, simplest ratio form would be 2:1. This also means that 2 ounces would be 1 cup.
Answer:
The intersection is point is (1/2 , 3)
Step-by-step explanation:
y = 4x + 1
y = -2x + 4
Next, move the x's to the side of the y's and change the positive to negative and vice versa.
y - 4x = 1
y + 2x = 4
Then, multiply the top or bottom equation by -1
-y + 4x = -1
y + 2x = 4
Or
y - 4x = 1
-y - 2x = -4
Then, subtract the y or add them to erase the y's
4x = -1
2x = 4
Or
-4x = 1
-2x = -4
Next, add or subtract the x's and what they equal
6x = 3
Or
-6x = -3
Then, find x
3/6x = 1/2
Or
-3/-6x = 1/2
x = 1/2
Finally, substitute 1/2 into one of the 2 equation
y= 2+1
y = 3
Or
y = -1 +4
y = 3
and get the point of (1/2 , 3)
Thanks for the Question
