I finished the test and here's the answer~!
3x+5y=25.75
8x+2y=29.00
So I first got what x is equal too.
8x+2y=29 8x+2y-2y=29-2y 8x=29-2y 8x/8=29/8-2y/8 x=3.625-0.25y
Next substitute x for the equation.
3(3.625-0.25y)+5y=25.75
10.875-0.75y+5y=25.75
10.875-10.875+4.25y=25.75-10.875
4.25y/4.25=14.875/4.25
y = 3.5
Now substitute y for 3.5.
8x+2(3.5)=29
8x+7-7=29-7
8x/8=22/8
x = 2.75
The price of a flower bouquet would be $2.75. Don't worry I got this question correct. :)
Hello,
it remainds 8 digits: 1,2,3,4,5,6,7,8
8*8*8=512 possibilities;
Answer: It is simple, if you look at the slope of the 2, if they have the same slope then it means it definitely is not intersecting, and if you look at which points that the equation begins at you can tell if it starts at the same points with the same slope then it is same line, if it starts at different points with same slope then it is parallel lines
Answer:
Step-by-step explanation:
1.5(x + 4) - 3 = 4.5(x - 2)
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
3 + 9 = 4.5x - 1.5x
12 = 3x
12/3 = x
4 = x <======
The number would be 12. If you substitute you will find that 12 is correct.
