Answer:
1.) (11, -7/3), 2.) No solution. 3.) (1, 3)
Step-by-step explanation:
1.)
2x + 3y = 15
x - 3y = 18
Solve...use elimination method
2x + x + 3y - 3y = 15 + 18
3x = 33
x =11
11 - 3y = 18
-3y = 7
y = -7/3
(11, -7/3)
---------------------------------------
2.) y = 4x + 4
y = 4x - 4
Use substitution.
4x + 4 = 4x - 4
4 = -4 FALSE NO Solution
3.) y = 5- 2x
4x + 3y = 13
Can use elimination method
2y = 10 - 4x
add it to 4x + 3y = 13
10 + 3y = 2y + 13
y = 3
3 = 5 - 2x
x = 1
(1, 3)
Answer:
It is 0.873 but rounded to hundredth is 0.87
Step-by-step explanation:
expression: (3.24-3/8+7/9-0.15) divided by 4
Solve: (3.24+7/9-3/8-0.15) divided by 4
= (3.24+0.78-0.375-0.15) divided by 4
=3.49/4
-0.873 = 0.87 to the nearest hundred
