Answer:
x=-32/29
Step-by-step explanation:
3x+4y=36 Equation 1
-5x+3y=35 Equation 2
Multiplying equation 1 with 3 (value before y in equation 2) and equation 2 with 4 (value before y in equation 1) we obtain equations 3 and 4 as follows
9x+12=108 equation 3
-20x+12y=140 equation 4
Subtracting equation 3 from equation 4 we obtain
-29x=32
x=-32/29
To find the value of y, we substitute the value of x into equation 2 as initially given in the equation
-5(-32/29)=35-3y
-5(-32/29)-35=-3y
55% of 125 is 68.75 because 55/100 or 0.55 times 125 equals 68.75.
Answer:
About $1.86
Step-by-step explanation:
It could be rounded to $1.90.
B is false. We know it can't be D, because that is a true statement. C is also true. Leaves A or B.
Well u could make a tree with the 2 numbers on top so one of the numbers on one tree and the other number on the other and then make a triangle so if the 2 numbers are 12 and 8 then you would put 8 on one and 12 on the other and then put a triangle under the 2 numbers and then lis the 2 numbers that multiply to get those answers so for 8 it would be 2 and 4 you would circle the 2 because it has nothing that can be multiplied to get it and keep going with 4 and get 2 and 2 and then circle the 2s then make a table and put the 2 2s in one column and then put the other 2 in another column then bring one number down from each column and multiply them together and you will get your answer if there are all different numbers then put them in all separate columns. Hope this helped!
