The answer to the equation is [tex]x=\frac{2}{7}[/tex]
First, you must add 12 on each side
[tex]14x=16-42x[/tex]
Then, you add 42x on each side
[tex]56x=16[/tex]
Finally, divide each side by 56
[tex]x=\frac{2}{7}[/tex]
The value of x = 2/7 which makes the equation 14x - 12 = 4 - 42x true.
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0.
14x - 12 = 4 - 42x
14x + 42x = 4 + 12
56x = 16
x = 2 / 7
Therefore, The value of x = 2/7 which makes the equation 14x - 12 = 4 - 42x true.

6(1+x)+x=-14
Answer:
X is equal to -10
Step-by-step explanation:
#1. Multiply 6 to (1+x). Doing this makes this equation: 6+6x+x=-14
#2. Then add 6x and x to get: 7x+6=-14
#3. Then move 6 to other side of equation, while at the same time, changing it's absolute value: 7x=-14-6
#4. now you have: 7x=-20, now just divide 7 by -20 WooHoo! You finished it! you have: -2.85714285714 or 2 and 43/50.

Step-by-step explanation:
Answer:
If you want to get the result like I did, Desmos is a great website that help you graph any kind of equation.
Step-by-step explanation:
I placed y=-5/2x +2 into desmos and it spat out this graph. If you want to do it algabreacly, I suggest making an x and y t-chart and start plugging in x numbers in terms of y. Lets say you plug in 1 as x, you would to 5/2(1) +2 giving you 2 5/2 or 4 1/2 as your y coordinate if x is 1. This makes your point (1, 4 1/2). I'd say do about 3 coordinates at least and then draw a line straight through those point giving you your graphed equation.

Anthony has a part-time job. He decides to save $10 for every $50 that he spends. Final question: If Anthony saved $60, how much money did he earn?
Answer:
300$
Step-by-step explanation:
If he save 10 for every 50, you just divide. 60/10 = 6. He saved 6 times, if each time he saves he has 50 extra dollars, 6 * 50 = 300 because 6*5 = 30 and there is a extra 0 so 30 and 0 is 300

Simon has a quarter, dime, nickel, and penny in his pocket. He wants to buy a snack at the canteen that costs 40¢. If he pulls out one coin at a time, what is the probability that the first 3 coins that are equal to $0.40?
The completed formula is ___c____3=____
There are___items. He will choose____
Answer:
It would be a 3/4 chance that he will pull the right 4 coins.
Step-by-step explanation:
The probability that the first 3 coins are equal to $0.40 will be 1/4
How to explain the probabaility?Q=event of pulling a quarter (25 cents)D=event of pulling a dime (10 cents)N=event of pulling a nickel (5 cents)P=event of pulling a penny (1 cent)Simon needs to pull out the penny last so that the first three coins add up to $0.40. We assume the coins are wrapped so it is a random choice.
For the first coin, the probability of not pulling a penny is 3/4, similarly, for the second coin, the probability of not pulling a penny is 2/3,
For the third coin, the probability of not pulling a penny is 1/2,
P(3 coins but no penny) = (3/4*2/3*1/2) = 1/4

What is true about the sign of the difference when a positive integer is subtracted from a negative integar
Answer:
negative
Step-by-step explanation:
Suppose we have positive integer x and negative integer -y.
Subtracting x from -y gives:
-y - x
Clearly, if -y is negative and we're subtracting even more (x) from it, the answer will still be negative.
So, the sign is negative.

Find the inverse, g−1(x), of the following function: g(x) = 4x - 11
Answer:
[tex]g^{-1}[/tex] (x) = [tex]\frac{x+11}{4}[/tex]
Step-by-step explanation:
let y = g(x) and rearrange making x the subject, that is
y = 4x - 11 ( add 11 to both sides )
y + 11 = 4x ( divide both sides by 4 )
[tex]\frac{y+11}{4}[/tex] = x
Change y back into terms of x , with x = [tex]g^{-1}[/tex] (x) , thus
[tex]g^{-1}[/tex](x) = [tex]\frac{x+11}{4}[/tex]

Please solve this question.
Ram started his journey at 6:00 AM with an average speed at 20km/hr.
Hari started his journey two hours later (at 8:00 AM) with an average speed of 30km/hr.
We have to find time at which they meet each other[tex].[/tex]
★ Let they meet each other after t hours wrt 6:00 AM.
At that time, distance covered by ram must be equal to the distance covered by hari.
We know that,
distance = speed × time➤ Distance covered by Ram :
⭆ d₁ = v₁ × t
⭆ d₁ = 20 × t
➤ Distance covered by Hari :
Since hari started his journey after 2 hours so will take time = (t - 2) hours
⭆ d₂ = v₂ × (t - 2)
⭆ d₂ = 30 × (t - 2)
⭆ d₂ = 30t - 60
Now,
➠ d₁ = d₂
➠ 20t = 30t - 60
➠ 30t - 20t = 60
➠ 10t = 60
➠ t = 6 hrs
∴ They will meet at (6 + t) = 12PM
Hope It Helps!Answer: 12:00 pm (Noon)
Step-by-step explanation:
Let t represent the time (in hours) from 6:00 am
Use distance (d) = rate (r) × time (t)
Ram: time = t, r = 20 → d = 20t
Hari: time = t - 2, r = 30 → d = 30(t - 2)
Use Substitution method to solve the system of equations:
20t = 30(t - 2)
20t = 30t - 60
-10t = -60
t = 6
They travel the same distance when Ram rides his bike for 6 hours
and Hari rides his bike for 4 hours.
Ram: 6:00 am + 6 hours = 12:00 pm (Noon)
Hari: 8:00 am + 4 hours = 12:00 pm (Noon) [tex]\checkmark[/tex]
