Answer:
The answer to your question is (3, 0)
Step-by-step explanation:
Data
4x + 2y = 12 Equation l
x - y = 3 Equation ll
Process
To solve this problem use the elimination method
1.- Multiply equation ll by 2
4x + 2y = 12
2x - 2y = 6
6x 0 = 18
2.- Solve for x
6x = 18
x = 18/6
x = 3
3.- Substitute x in equation ll to find y
3 - y = 3
-Solve for y
-y = 3 - 3
y = 0
4.- Write the solution
(3, 0)
Answer:
676
Step-by-step explanation:
d1×d2/2
42×56/2
1352/2=676
please check it by doing again
2*5 = 10
2*2 = 4
4(10) + 2(4) = 40 + 8 = 48
ans) 48cm
Answer:can you give me more detail
Step-by-step explanation:
Harry can rake the leaves in the yard 8 hours faster than his little brother Jimmy can.
<span>If they join to work together they can complete the job in 3 hours. </span>
<span>1/x + 1/(x - 8) = 1/3 </span>
<span>3(x - 8) + 3x = x(x - 8) </span>
<span>x^2 - 14x + 24 = 0 </span>
<span>(x - 12)(x - 2) = 0 </span>
<span>Solutions: </span>
<span>x = 2 </span>
<span>x = 12 </span>
<span>Jimmy can complete the job on his own in 12 hours.</span>
