Answer:
$5 per hour
Step-by-step explanation:
25/5 = 5
10*5 = 50
Correct answer is A. For example 50/2= 25 which is odd
Answer:
A) x = 3 or -1
B) x = -7
C)x = -7
Step-by-step explanation:
A) x² + 2x + 1 = 2x² - 2
Rearranging, we have;
2x² - x² - 2x - 2 - 1 = 0
x² - 2x - 3 = 0
Using quadratic formula, we have;
x = [-(-2) ± √((-2)² - 4(1 × -3))]/(2 × 1)
x = (2 ± √16)/2
x = (2 + 4)/2 or (2 - 4)/2
x = 6/2 or -2/2
x = 3 or -1
B) ((x + 2)/3) - 2/15 = (x - 2)/5
Multiply through by 15 to get;
5(x + 2) - 2 = 3(x - 2)
5x + 10 - 2 = 3x - 6
5x - 3x = -6 - 10 + 2
2x = -14
x = -14/2
x = -7
C) log(2x + 3) = 2log x
From log derivations, 2 log x is same as log x²
Thus;
log(2x + 3) = logx²
Log will cancel out to give;
2x + 3 = x²
x² - 2x - 3 = 0
Using quadratic formula, we have;
x = [-(-2) ± √((-2)² - 4(1 × -3))]/(2 × 1)
x = (2 ± √16)/2
x = (2 + 4)/2 or (2 - 4)/2
x = 6/2 or -2/2
x = 3 or -1
Answer:
each box has 52 in it
Step-by-step explanation:
first you subtract 288 from 548 =260
this is the total number of nails minus the total 1 inch nails
then you divide 260 by 5 because he has five boxes of 2 inch names which means that you have to account for the even number of nails in each box
Answer:
It can cover a distance of 100m.
Step-by-step explanation:
Given that:
Speed = v = 10m/s
Time = t = 10s
We know that:
Distance = Speed * Time
d = v*t
d = (10m/s)*(10s)
d = 100m
