Answer:
? = 15a^2
Step-by-step explanation:
We assume you want

Answers
Answer:
x = -5
Step-by-step explanation:
4 – 2(x + 7) = 3(x + 5)
Distribute
4 - 2x-14 = 3x+15
Combine like terms
-2x-10 = 3x+15
Add 2x to each side
-2x-10 +2x= 3x+15+2x
-10 = 5x+15
Subtract 15 from each side
-10-15 = 5x+15-15
-25 = 5x
Divide by 5
-25/5 = 5x/5
-5 =x
Answer:
x = -5
Step-by-step explanation:
4 - 2(x + 7) = 3(x + 5)
so, let's do the multiplications. remember, when two terms are multiplied, then everything of the left is multiplied with everything on the right. and a "-" flips signs.
2(x + 7) = 2x + 14
3(x + 5) = 3x + 15
so, in total
4 - 2x - 14 = 3x + 15
now, we add combinable things together, and we can also move things from one side of the equation to the other (by adding our subtracting the same thing on both sides, so that the value of the expression remains unchanged).
-2x - 10 = 3x + 15
-25 = 5x
and now, what applied to adding and subtracting also aims to multiplication and division. again, it is important to do the same thing to both sides.
-5 = x
If there are 3.28 feet in a meter , how many are in the 110 meter dash?
Answers
360.8
Explanation:
3.28*110
In 110 meter dash, there are 360.8 feet.
What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given that, there are 3.28 feet in a meter
Since,
in 1 meter there are = 3.28 feet
Thus in 110 meters there are = 3.28 * 110 feet
In 110 meters, there are = 360.8 feet
Therefore, there are 360.8 feet in 110 meters dash.

If (x - 4) varies inversely as (y + 3) and x = 8 when y = 2, what is x when y = - 1?
Answers
Answer:
[tex]x=14[/tex]
Step-by-step explanation:
If two values are inversely proportional, their product must be maintained. That way, if one value goes up, the other goes down by the same extent.
Therefore, if [tex](x-4)[/tex] and [tex](y+3)[/tex] vary inversely, their product will be the same for all values of [tex]x-4[/tex] and [tex]y+3[/tex].
Let [tex]x=8[/tex] and [tex]y=2[/tex] as given in the problem. Substitute values:
[tex](8-4)(2+3)=(4)(5)=20[/tex]
Hence, the maintained product is [tex]20[/tex].
Thus, we have the following equation:
[tex](x-4)(y+3)=20[/tex]
Substitute [tex]y=-1[/tex] to find the value of [tex]x[/tex] when [tex]y=-1[/tex]:
[tex](x-4)(-1+3)=20,\\(x-4)(2)=20,\\x-4=10,\\x=10+4=\boxed{14}[/tex]

Step-by-step explanation:
I find the easiest way to draw a graph is to let a graphing calculator do it. That result is shown in the attachment.

If you're drawing this by hand, it can be easier if it is simplified a bit.
2(x +1) = 3(y -1) -4
2x +2 = 3y -3 -4 . . . . . . eliminate parentheses
2x +9 = 3y . . . . . . . . . . add 7
y = 2/3x +3 . . . . . . . . . divide by 3
This is the equation of the line in slope-intercept form. It tells you that the point (0, 3) on the y-axis is on the line, and that it has a slope of 2/3. That means it has a rise/run of 2/3, or a rise of 2 units for each 3 units to the right.
Starting from point (0, 3), another point on the line will be 3 over and 2 up, at (3, 5). Once you have a couple of points plotted, you can draw the line through them to make your graph.
