Answer:
The answer to your question is below
Step-by-step explanation:
Question 1
x = 5 Equation l
2x + y = 10 Equation ll
- Substitute Equation l in equation ll
2(5) + y = 10
y = 10 - 10
y = 0
- Solution (5, 0)
Question 2
x + 16y = 20 Equation l
x = 4y Equation ll
Substitute equation ll in equation l
4y + 16y = 20
20y = 20
y = 20/20
y = 1
-Find x
x = 4(1)
x = 4
-Solution
(4, 1)
Question 3
2x + 8y = 20 Equation l
x = 2 Equation ll
-Substitute equation ll in equation l
2(2) + 8y = 20
4 + 8y = 20
8y = 20 - 4
8y = 16
y = 16/8
y = 2
- Solution
(2, 2)
The plane starts at 202 m.
All altitudes are in meters.
After 1 second, it is at 202 - 1.8
After 2 seconds, it is at 202 - 1.8 * 2
After 3 seconds, it is at 202 - 1.8 * 3
etc.
After x seconds, it is at 202 - 1.8 * x
202 - 1.8 * x is the same as 202 - 1.8x
Answer: F. t(x) = 202 - 1.8x
Answer:
A. 2
Step-by-step explanation:
Its successive multiples and it increases:
+2, +4, +6, +8
it increases by 2 every time which is successive multiples so the answer is A, 2.
Answer:
The width of the yard is approximately 6 feet.
Step-by-step explanation:
1 cubic yard = 27 cubic feet. Then we must find the number of cubic yards.
So we know for 1 cubic yard = $98
And for "x" cubic yard = $58.07
1/x =98/58.07
x = 0.5925
After we figure this out we need to convert this into cubic feet
1 cubic yard = 27 cubic feet
0.5925 cubic yard = x cubic feet
1/0.5925= 27/x
x = 15 .99 cubic feet
So,
width x height x length = 16 cubic feet
w x 8 x (1/3) = 16
w = 48/8 = 6 feet
So:
The answer is:
The width of the yard is approximately 6 feet.
Hope this helps, have a good day. c;
