Answer:
$5.65
Step-by-step explanation:
1.20x0.50=0.60
1.50x2.50=3.75
0.60+3.75=4.35
10.00-4.35
5.65
here, x = 2
putting the value of x in the equation we get:
6x-7y=-9
or, 6×2- 7×y=-9
or, 12- 7×y= -9
or, 7×y =-21
so, y = -3
If you would like to know how much rope do they need, you can calculate this using the following steps:
42 yards * 2 + 36 yards * 2 = 42 * 2 + 36 * 2 = 84 + 72 = 156 yards
They will need 156 yards long rope.
No, because if it was 2 gal. per min., then the first coordinates would be (1,2)
Answer:
v×w = -6i-12
Step-by-step explanation:
hello :
Let v=-3i and w=2 - 4i.
v×w = -3i(2-4i) = -6i+12i² = -6i-12 ... i² = -1
