Answer:
1. 14
c. FD=ED
Step-by-step explanation:
1. 3x+28=5x -3 from both sides get:
25=2x Divide both sides by 2 and get
x=14
Step 1: Rewrite the equation
-14+6b+7-2B=1+5b
Step 2: Combine like terms
-14+6b+7-2b=1+5b
-7+4b=1+5b
Step 3: To isolate b, first add 7 on both sides
-7+4b=1+5b
+7 +7
_________
4b=8+5b
Step 4: Again, trying to isolate b, subtract 5b on both sides
4b=8+5b
-5b -5b
_______
-b=8
Step 5 (final step): Because the variable cannot be negative for a final answer, multiply each number by -1.
-1(-b=8)
b= -8
Final Answer: b=-8

100 = 10 * 10
It would be 10^2
Answer:
96 liters
Step-by-step explanation:
Two liters are in each bottle, so that means they sold 12 bottles of oil each day. Multiply that with 8 days to get the answer:
12 × 8 = 96
Ninety-six liters.
Answer:
-2.25
Step-by-step explanation:
We have that the mean (m) is equal to 500, the standard deviation (sd) 20
They ask us for P (x <455)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / sd
We have all these values, replacing we have:
z = (455 - 500) / (20)
z = -2.25
