We have the 2 equations
1- ) 5x-8y=6
2-) -6x-3y=18
multiplying the first equation by 3 and the second equation by 8 then subtracting
1-) 15x-24y=18
2-) -48x-24y=144
-48x-24y=144
(-) 15x-24y=18
-------------------------------------
-63x = 126
x=-2
substituting in equation 1
5(-2)-8y=6
-10-8y=6
-8y=16
y=-2
the soultion is (-2,-2)
Answer:
125600
Step-by-step explanation:
Please specify your answer better next time.
1. If you just want to replace all the "x" with 10, then it would be 403.140100
2. If x is a variable, then 4(10)(3.14)(10)(100)=125,600
This is equal tio the diameter of the circle formed:-
152 ins = circumference and this = pi * diameter
so the Answer is 152 / pi = 48.4 ins to nearest tenth
48 inches to nearest inch.
Each student gets 5 sheets of paper
First what you do is you divide 24 by 4 which equals 7
then you divide 35 by 7 which is 5.
Hope this helps
