We can easily solve this by assuming a linear equation.
The general form is:
y = m x + b
where y is the price of gas, x is the year, m is the
slope or increase in price every year and b is the y-intercept
We can solve the slope by:
m = (3.25 – 1.75) / (2013 – 2003)
m = 0.15
y = 0.15 x + b
Using any pair data, we get the b:
3.25 = 0.15 (2013) + b
b = -298.7
y = 0.15 x – 298.7
Answer:
x= -8
Step-by-step explanation:
Let's solve your equation step-by-step.
(x+6)(3)=−6
Step 1: Simplify both sides of the equation.
(x+6)(3)=−6
(x)(3)+(6)(3)=−6(Distribute)
3x+18=−6
Step 2: Subtract 18 from both sides.
3x+18−18=−6−18
3x=−24
Step 3: Divide both sides by 3.
3x
3
=
−24

x=−8
For the product of the digits to be divisible by 10, it must have 10 as a factor, of course. Since 10 can't act as a digit, this means two of our digits must be 2 & 5.
No digit can be 0 because this would give a total product of 0.
Neither 2 nor 5 can be our largest because the lowest you can get is 1+2+3=6.
The lowest possible largest digit would have to be 1+2+5=8.
As for 9, this is not an option, and here's why: We need that 2 and 5, but to get 9 our other digit would have to be 2, which is a repeat.
So, our digits are 1, 2, 5, and 8.
It doesn't matter which order they are in. (take a look at the rules)
Therefore, we should put the highest digits in the highest value places.
The answer is
The answer is 60. the second answer choice. 180-60=120.
1.2 times 15 = 18 so your answer will be A
