Answer:
(-1, 3)
Step-by-step explanation:
x - 5y = -16 [Equation 1]
-x + 3y = 10 [Equation 2]
<u>Adding both equations</u>
- x - x - 5y + 3y = -16 + 10
- -2y = -6
- y = 3
- x - 5(3) = -16
- x - 15 = -16
- x = -1
<u>Solution</u> : (-1, 3)
Answer:
72 People
Step-by-step explanation:
Find out what is 35% of 360 is (126)
Find out what is 45% of 360 is (162)
Add the two numbers (288)
Subtract from 360 (72)
Answer:
t= -4
Step-by-step explanation:
t/2-16= -18
first add 16 to both sides
t/2-16+16= -18+16
t/2= -2
now multiply both sides by 2
(t/2)2=-2(2)
t= -4
answer check:
substitute the variable for -4
-4/2-16= -18
-4/2= -2
-2-16= -18
-18= -18
Answer: The correct option is C
X value is between 2 and 7 on number line.
Step-by-step explanation:
Given compound inequality is -6<3x-12<9
To simplify the inequality:
Step1 : Add 12
-6+(12)<3x-12+(12)<9+(12)
6<3x<21
Step2: Divide by 3
2<x<7
Therefore, X value is between 2 and 7 on number line.
The correct answer is C
