expand and simplify 3(8x - 2) +2 ( 4x - 1 )
Answer: 32x-8
Step-by-step explanation: 8x times 3 is 24x and 4x times 2 is 8x
24x +8x is 32x
3 times-2 is -6 2 times-1 is -2
-6-2 is -8
so therefore the answer is 32x-8
Share 120 hours in the ratio 5:7.
When 120 hours shared in the ratio it gives 50 hours : 70 hours
Lets add up the ratio= 5 + 7 =12
Now for 5/12 of the time = 5/12 × 120
= 50 hours
And for 7/12 of the time = 7/12 × 120
= 70 hours
What is ratio?A ratio in mathematics describes the amount of times one number is present in another. For instance, the proportion of oranges to lemons in a bowl of fruit is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3). The proportions of oranges to the overall amount of fruit are 8:14 for oranges and 6:8 (or 3:4) for lemons (or 4:7).
The quantities in a ratio can be of any form, including counts of people or things, measures of lengths, weights, or times, etc. Both numbers must be positive in the vast majority of situations.

The water level of a river was measured each day during a two-week period. The graph models the linear relationship between the water level of the river in feet and the number of days the water level was measured. Which statement best describes the y-intercept of the graph?
Answer:
c
Step-by-step explanation:
The y-intercept of a graph is the point where the graph touches the y-axis.
The best describes the y-intercept of the graph is (a) the initial water level of the river is 16 ft
From the attached graph, we observe that the graph crosses the y-axis at y = 16
This value represents the initial value of the graph.
In other words, the initial water level of the river
So, the y-intercept means that:
The initial water level of the river is 16 ft
Hence, the true statement is (a)

7x = 9x-2
2 = 2x
x = 1
y = 7
Answer:
(1,7)
Step-by-step explanation:
okay, since the equations are both equal to y we can set the equations to be equal to each other and solve for x
9x - 2 = 7x
subtract 9x from both sides
-2 = -2x
divide both sides by -2
x = 1
now that we have the x-value we can plug it back in to get a y-value
y = 7x
y = 7(1)
y = 7

If the total price for two cars at a dealership is $91,000, where one car's price is
$11,000 less than twice the other, what is the price of the cheaper vehicle?
The price of the cheaper vehicle is $34000. And the price of the other vehicle is $ 57000. The total becomes $91000.
The total price for two cars at a dealership is $91,000, where one car's price is $11,000 less than twice the other.
There are numerous ways in which one may define an equation. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math.
Let the price of one car be 'X' and other be 'Y' such that:
X+Y = $91000.
According to the question,
X = 2Y - $11000
Manipulating and calculating both the equations we get,
X = $57000 and Y = $34000.
So the cheaper car is of $34000.

1.) To find the opposite of 10−x, find the opposite of each term:[tex]10[/tex] × [tex]-1=-10[/tex][tex]-x[/tex] × [tex]-1=-x[/tex]- This is another way of saying multiply each side by -1.
2.) Find the opposite of −x:[tex]-x=x[/tex]
- Since we have 2 negatives next to each other, one must be turned into a positive, in this case it's the x.
3.) Combine −7x and x:[tex]-7x+x=-6x[/tex]
- Combine them because you can only have one variable (x) in the end.
4.) Add 10 to both sides:[tex]-10+10=[/tex][tex]-58+10=-48[/tex]

5.) Divide both sides by −6:[tex]-6x[/tex] ÷ [tex]-6=x[/tex][tex]-48[/tex] ÷ [tex]-6=8[/tex]- We do this to get x alone with one number left over, and the only way to do so is to cancel everything out by dividing.

Step-by-step explanation:
Step 1: Define Equation
6(x - 1) = -72
Step 2: Solve for x
Divide 6 on both sides: x - 1 = -12Add 1 to both sides: x = -11Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 6(-11 - 1) = -72Subtract: 6(-12) = -72Multiply: -72 = -72Here we see that -72 does indeed equal -72.
∴ x = -11 is a solution to the equation.
Answer:
x = - 11
Step-by-step explanation:
Given
6(x - 1) = - 72 ← divide both sides by 6
x - 1 = - 12 ( add 1 to both sides )
x = - 11
