Answer:
find fist the lcm and gcf for each data
Answer:
It has more than one equal sign but set up like this:
Step-by-step explanation:
Let's solve for x.
y+x−1+
3
2
=−y
Step 1: Add -y to both sides.
x+y+
1
2
+−y=−y+−y
x+
1
2
=−2y
Step 2: Add (-1)/2 to both sides.
x+
1
2
+
−1
2
=−2y+
−1
2
x=−2y+
−1
2
Answer:
x=−2y+
-1/2
Answer:
3(x + 8y)
Step-by-step explanation:
Find the GCF:
Factors of 3: 3, 1
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Since 3 is the greatest common factor, it is the GCF.
Factor using this number:
3x + 24y
(divide by 3 to see what numbers + variables will be in the parentheses)
3x + 24y
/3 /3
x + 8y
Factor:
3(x + 8y)
Answer:
The correct statement is
The null hypothesis is 
The alternative hypothesis is 
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.18
The sample size is n = 1240 airplane
The number of airplane is k = 310
Generally the sample proportion is
=> 
=> 
The null hypothesis is
The alternative hypothesis is
Answer:
Step-by-step explanation:
-7x-2y=-13
x-2y=11
(subtract the first inequality from the second)
-7x-x = -8x
-2y-(-2y) = 0
-13-11= -24
-8x=-24
x=3
(now place the x value into the second inequality)
3-2y=11
-2y=11-3
-2y=8
y=-4
x=3
y=-4
