Answer:
1 whole mile
Step-by-step explanation:
the LCD is 15. 5x3=15. what we do to the denominator we do to the top so 1x3=3 now we have 3/15.
now do that with the other fraction
3x5=15
2x5=12
12/15+3/15= 15/15= 1 whole
We are given a polynomial representing the area of a barnyard that is <span> 4x2 + 8x - 21. A rectangle's area is equal to length multiplied by the width which means we can use factoring.
</span><span> 4x2 + 8x - 21
(2x - 3 ) (2x + 7)
we can countercheck this to verify the polynomial.
In this case, the dimensions are </span> 2x - 3 and 2x + 7.
Answer:
The required null and alternative hypotheses are and respectively.
Step-by-step explanation:
Consider the provided information.
If there is no statistical significance in the test then it is know as the null which is denoted by , otherwise it is known as alternative hypothesis which denoted by .
The claim is: The proportion of crimes committed after dusk will fall below the current level of 0.84
The null hypothesis is The proportion of crimes committed after dusk will same as the current level of 0.84.
Therefore,
Hence, the required null and alternative hypotheses are and respectively.
Answer:
a) v = 0
b) b = 7 / 6
c) a = any number
Step-by-step explanation:
a) 7(2+5v)=3v+14
7 x 2 + 7 x 5v = 3v + 14 .... distributive
14 + 35v = 3v + 14
35v - 3v = 14 - 14
32v = 0
v = 0 ...... only v value can fit
b) -3 (3-6b)=6b+5
-9 + 18b = 6b + 5
18b - 6b = 5 + 9
12b = 14
b = 14 / 12 = 7 / 6
c) 2 (a-2)=2a-4
2a - 4 = 2a - 4
2a -4 + 4 = 2a -4 + 4
2a = 2a
a = a ........ a cab be any number
