Answer:
x<25
Step-by-step explanation:
Let's solve your inequality step-by-step.
2.4x−9<1.8x+6
Step 1: Subtract 1.8x from both sides.
2.4x−9−1.8x<1.8x+6−1.8x
0.6x−9<6
Step 2: Add 9 to both sides.
0.6x−9+9<6+9
0.6x<15
Step 3: Divide both sides by 0.6
0.6x/0.6 < 15/0.6
x<25
D) 4.5 Standard Deviations Above the Mean
All you have to do is add .2 to 6.6 until you reach 7.5
6.8
7.0
7.2
7.4
Then you only need half of .2 to reach 7.5, so it's 4.5 standard deviations above the mean
Y=x+4
3x+Y=-8
3x+x+4=-8
X=-3. Substitute the value of x
Y=-3+4
Y=1
(X,Y)= (-3,1)
So the answer is C
Answer:
25/64
Step-by-step explanation:
do what's inside parentheses first
-3/8 - 2/8 = -5/8
-5/8(-5/8) = 25/64
