10. b - 16.6 = -3.7.....add 16.6 to both sides
b - 16.6 + 16.6 = -3.7 + 16.6
b = -3.7 + 16.6
b = 12.9
14. 18.91 = -7.9 + x.....add 7.9 to both sides
18.91 + 7.9 = -7.9 + 7.9 + x
26.81 = x
16. 295.8997 = -10.1k....divide both sides by -10.1
295.8997 / -10.1 = (-10.1/-10.1)k
- 29.297 = k
18. -94.4724 = 3.3x....divide both sides by 3.3
- 94.4724 / 3.3 = (3.3 / 3.3)x
- 28.628 = x
20. -29.4x = -148.764...divide both sides by -29.4
(-29.4 / -29.4)x = - 148.764 / -29.4
x = 5.06
Let m be the distance (in miles) she runs in a month
and w be the distance (in miles) she runs in a week
since the total distance she run in a week is one third of what she run in a month, in equation form
w = m/3
to calculate the distance she run in a month,
m = 3w
m = 3(6 miles)
m = 18 miles in a month
Answer:
40k^2(3k - 2) + 48(3k - 2)
(40k^2 + 48)(3k - 2)
8(5k^2 + 6)(3k -2)
Step-by-step explanation:
P=28 in
l=3*w-2
p=2w+2l
p=2w+2*(3w-2)
p=2w+6w-2*2
p=8w-4
p=28 in
8w-4=28
8w=28+4
8w=32 in
w=32/8=4 in
l=3*4-2=12-2=10 in
Answer:
8530
Step-by-step explanation:
The remainder is 5⁵ + 2(5)⁴ + 9(5)³ - 6(5)² + 3(5) + 3165 = 8530
