Answers
Answer:
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
To solve, move all the x’s to one side and all the numbers. Remember when moving numbers to the other side of an equation, the sign changes from either a positive to a negative or vise versa.
9 + 3 = 4/3x + 2/3x
Next, add the like terms.
9+3=12
When adding fractions, add the numerator (top number), but first change denominator (bottom number) if not the same. Here, we don’t need to.
4/3x+2/3x=6/3x
So,
12 = 6/3x
Then, we have to divide each side by 6/3 to make the x alone.
12/6/3 = 6/3x/6/3
To divide with fractions, multiply the reciprocal (opposite number on number line):
12/1·3/6 = x
36/6 = x
6 = x

3) Car A and B travel in opposite directions. Both cars leave the same location at the same time. Car A is traveling west at a speed of 10 mph more than Car B, which is headed east. Find the speed of Car A if the two cars are 300 miles apart after traveling 3 hours. Chart is optional. Include units in your answer. *
Answers
Let, speed of car B is -x.
So, speed of car A is x + 10.
Relative speed of A w.r.t B is ,
[tex]v_{ab}=(x+10)-(-x)\\\\v_{ab}=2x+10\ mph[/tex]
So, time taken by A to travel 300 miles relative to B given by 3 hours .
[tex]v_{ab}=2x+10\\\\\dfrac{300}{3}=2x+10\\\\x = 45 \ mph[/tex]
Therefore, speed of car A is 45 + 10 = 55 mph.
Hence, this is the required solution.
7x^2– 19x – 6
How do I factorize this expression?
Answers
I am not sure so sorry if it is wrong
Answer:
x = 3 and x = -2/7
Step-by-step explanation:
you can multiple -6 by 7 = -42
and then find what adds into -19 but can multiply together to get -42.
In this case (x-21)(x+2) would work
then you have to divide out your 7 from both numbers,
(x-21/7)(x+2/7)
then you have to make them equal to zero
x-21/7 = 0 = x = 21/7 = 3
x+2/7 = 0 = x = -2/7
so your final answer is x = 3 and x = -2/7

Answers
Given :
Fresh Farm: $4.50 for 5 lbs
Fruit Garden: $1/5 for 1/3 lb
Mother Nature: $4 for 5 lbs
Country Market: $0.85 per pound
To Find :
Which store offers the lowest unit rate for cantaloupes, in dollars per pound.

Dollar per pound of each store :
Fresh Farm : 4.50/5 = $0.9 per pound
Fruit Garden: (1/5)/(1/3) = $0.6 per pound
Mother Nature: 4/5 = $0.8 per pound
Country Market: $0.85 per pound
From above we can see that Fruit Garden offers lowest unit rate.
Hence, this is the required solution.
How many quarts of water must be added to 7 qts of a 19% saline solution to obtain a 5% saline solution?
Answers
Answer: quantity of water added = 19.6 quarts
Step-by-step explanation:
Let x= quantity of water added
Then, Quantity of saline in 7 quarts solution = 19% of 7 = 0.19 (7)=1.33 quarts [to remove % divide number by 100]
When x quarts water is added , the quantity of solution becomes = x+7
Quantity of saline in it= 5% of (x+7)= 0.05(x+7)
Now, quantity of saline remains same, so
[tex]1.33= 0.05(x+7)\\\\\Rightarrow\ 1.33x=0.05x+0.35\\\\\Rightarrow\ 1.33-0.35=0.05x\\\\\Rightarrow\ x=\dfrac{0.98}{0.05}=19.6[/tex]
Hence, quantity of water added = 19.6 quarts

Answer:
9 I think
Step-by-step explanation:
I wanted to simplify 12 out of 15 and I did by dividing 3 out of both of them which would now equal 4 out of 5. I know that 4 out of 5 is 80%. so, I did 80 % of 45 which equals 36 which means 36 people were in band. So now you minus 36 from 45 which is 9
9 people did not play in band
