What is the problem, can you write it better pls?
Answer:
x = - 3 and x = 1
Step-by-step explanation:
4x - 2 - 2x = x - 5, that is
2x - 2 = x - 5 ( subtract x from both sides )
x - 2 = - 5 ( add 2 to both sides )
x = - 3
----------------------------------------
- (x + 3) = 2x - 6 ← distribute left side
- x - 3 = 2x - 6 ( subtract 2x from both sides )
- 3x - 3 = - 6 ( add 3 to both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1
Explain two different ways to find a new value after an original value is increased by 30%.
Answer:
Frequently, we know the new amount and the percent change and need to know the original amount. We found that a $600 TV on sale for 30% off, cost $420 on sale. We might think, that to find the original cost of the TV that has a sale price of $420 after a sale of 30% off, we could just take 30% of the $420 cost and add it back to the $420 to find the original cost.
30% of $420 is 0.30($420) = $126 and $420 + $126 = $546.
Or, 130% of $420 is 1.3($420) = $546.
Notice that this is not the $600 original list price with which we started.

Write an equation of the line that passes through the point (-12, 6) and is parallel to the graph of the equation y=-1/6x + 1. Explain your reasoning.
Answer:
y=-1/6x+4
Step-by-step explanation:
In order to pass that point, you have to move the line up 4 points. So you make the 1 at the end to 4.
Mario made 2 goals for every 5 shots on goal. What is the probability that Mario would make 2 goals on two shots?
Answer:
16%
Step-by-step explanation:
To calculate this we first need to calculate the probability of Mario scoring for every individual shot that he takes. Since he makes 2 goals for every 5 shots on average, we simply divide these numbers to get the probability of a goal per shot.
2 / 5 = 0.4 ...multiply by 100 to get percentage value
0.40 * 100 = 40%
We see that the probability of scoring a goal per shot is 40%. Now we need to multiply this probability twice to get the probability of scoring 2 consecutive goals in two shots.
0.40 * 0.40 = 0.16 ... multiply by 100 to get percentage value
0.16 * 100 = 16%
Answer:
16%
Step-by-step explanation:
I know that 2/5 = 0.4 or 40%
and 0.4 x 0.4 = 0.16
or 16%

Select the solution(s) of log2x=1−log(x+4).
Step-by-step explanation:
log2x = 1 - log(x+4)
log2x = log10 - log(x+4)
log2x = log[10/(x+4)]
2x = 10/(x+4)
2x(x+4) = 10
2x² + 8x - 10 = 0
÷2 both sides of equation
x² + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5, 1
x isn't be -5 because logA, A need to be > 0
So, x value is 1
A certain model car has a keypad with 5 numbers on the door. To open the door, 5 numbers must be entered in the correct
order and no number can be used more than once. What is the probability that someone could guess the correct code?
OA. Ito
OB.
OC.
OD.
Answer: A. [tex]\dfrac{1}{120}[/tex]
Step-by-step explanation:
Total digits on keypad = 5
According to permutation,
If repetition of digits is not allowed then the number of 5-digits passwords can be formed = 5!
= 5 x 4 x 3 x 2 x 1 [n!=n x (n-1) x (n-2)x ... x 1]
=120
The probability that someone guesses the correct code = [tex]\dfrac{\text{Number of correct codes}}{\text{Total possible codes}}[/tex]
[tex]=\dfrac{1}{120}[/tex]
Hence, the correct option is A.

Kenji drives 18.4 miles in 16 minutes. He passes a sign, which gives the speed limit as 60 mph. By how much, in mph, did Kenji's average speed exceed the speed limit?
The amount of speed by which kendri exceeded the speed limit is; 9 mph
We are given;
Distance; d = 18.4 miles
Time; t = 16 minutes = (16/60) hours
Now, the formula for speed is;
Speed = distance/time
Thus, let's Calculate kenji's speed;
Kenji's speed = 18.4/(16/60)
Kenji's speed = 69 mph
We are told that the speed limit is to be 60 mph, this means that kendri exceeded the speed limit by;
69 - 60 = 9 mph

If the expression
(3v+7) - (8v+6)
needs to be equivalent to
(-5+n)
What is the value of n?
Answer:
n = 1
Step-by-step explanation:
So the first step is to simplify the top equation:
(3v + 7) - (8v + 6)
distribute the negative sign to get rid of the second parentheses:
3v + 7 - 8v - 6
now, combine like terms
-5v + 1
Since it says it needs to be equivalent to (-5v + n), n is 1
what fraction is equivalent to 3/9
Answer:
the simplified version of 3/9 would be 1/3 but other equivalent fractions of 3/9 would include but are not exclusive to: 2/6, 4/12, 5/15, and etc.
The required fraction 3/9 is equivalent to 1/3.
Given that the fraction is 3/9.
Equivalent fractions are the fractions are same at their simplest form.
Let a/b be the fraction, then the equivalent fractions are
2a/2b, 3a/3b, 4a/4b, 5a/5b, etc
To find an equivalent fraction, we simplify the given fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).
In this case, the GCD of 3 and 9 is 3.
Dividing both 3 and 9 by 3, we get:
3 ÷ 3 = 1
9 ÷ 3 = 3
Therefore, the fraction 3/9 simplifies to 1/3, which is an equivalent fraction.

Which expression is equivalent to (-5/6) / (10/3)?
Answer:
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}[/tex]
Let us solve the expression
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=\frac{-\frac{5}{6}}{\frac{10}{3}}[/tex]
Apply fraction rule: [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]=-\frac{\frac{5}{6}}{\frac{10}{3}}[/tex]
Divide fractions: [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex]
[tex]=-\frac{5\cdot \:3}{6\cdot \:10}[/tex]
Multiply the numbers: [tex]6\cdot \:10=60[/tex]
[tex]=-\frac{5\cdot \:3}{60}[/tex]
Multiply the numbers: [tex]5\cdot \:3=15[/tex]
[tex]=-\frac{15}{60}[/tex]
Cancel the common factor: 15
[tex]=-\frac{1}{4}[/tex]
Therefore, we conclude that the equivalent expression is:
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]
