Answer: 180, 185, & 190
<u>Step-by-step explanation:</u>
1st #: 5x
2nd #: 5(x + 1)
3rd #: 5(x + 2)
1st # + 2nd # + 3rd # = sum
5x + 5(x + 1) + 5(x + 2) = 555
15x + 15 = 555
15x = 540
x = 36
1st #: 5x = 5(36) = 180
2nd #: 5(x + 1) = 5(36 + 1) = 185
3rd #: 5(x + 2) = 5(36 + 2) = 190
Answer:
Step-by-step explanation:
volume of rectangular prism = length * breadth * height
=6m * 5.5m * 4.5m
=148.5 m^3
Answer:
First image: (6, -1)
2nd image: y = 63
Explanation:
1)
2x + y = 11
1/2x - 5y = 8
y = -2x + 11
1/2x - 5(-2x + 11) = 8
1/2x + 10x - 55 = 8
10.5x - 55 = 8
10.5x = 63
x = 6
2x + y = 11
2(6) + y = 11
12 + y = 11
y = -1
(x , y) = (6, -1)
2)
1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5
2y - 1.2 = 1.8y + 10.8 + 0.6
0.2y - 1.2 = 11.4
0.2y = 12.6
y = 63
