The answer for that question is no you will need a ratio
To solve a problem like this, you will need to use substitution or elimination. For the sake of an example I will solve this using substitution.
First, solve one of the equations for x or y:
3x-5y=-39
3x=-39+5y
X=(-39+5y)/3
Then substitute for the value of x in the second equation:
6x+2y=-42
6((-39+5y)/3)+2y=-42
Solve for y:
-78+10y +2y=-42
-78+12y=-42
12y=36
Y=3
Once you've solved for y, you can plug in it's value to find x:
X=-39+5(3)/3
X=-24/3
X=-8
So, we can conclude that the correct answer is B. (-8,3)
Answer:
Step-by-step explanation:
A. The regular cost is 55 per person. Using the given variable definitions, that cost can be expressed as ...
y = 55x
__
B. The party special cost is 46 per person, with an added fee of 45. That cost can be expressed as ...
y = 46x +45
_____
As you know, the cost of a purchase is the product of the cost of an item and the number of items. Here, the cost of entry is the cost of the item of interest, and the number of persons needing entry is the number of items. The party special has the addition item of a private room, so its cost is added to the total for the party special.
All you would do is divide 9.99/15 to get how much one pound costs.
The answer would be around 66 or 67 cents.
9.99/15=.666
Answer with explanation:
To find the common multiple of 45 and 95,we will find HCF of 45 and 95.
45=3 × 3× 5
95=5 × 19
⇒H CF(45,95)
=3 × 3×5×19
=855
→Common multiple of 45 and 95 =855
→There are infinite number of multiple of 855 which are 855, 1710, 2565,.....
You have not written between which two numbers.So, you should write multiple of 855 such that it is smaller than the greater number.
