Answer:
13.39285714285714
Step-by-step explanation:
Using the order of operations (P.E.M/D.A/S), we work from left to right starting with multiplication and division.
Start with the multiplication
2 x 123 = 246
Then the adjacent division
246/56 = 4.392857142857143
Last, we work any addition or subtraction
4.392857142857143 + 9 = 13.39285714285714

What is an equation of the line that is perpendicular to -x+3y=9 and passes through the point (-3,2)
Answer:
y=-3x-7
Step-by-step explanation:
the line is currently in standard form (ax+by=c). Let's put it into slope-intercept form (y=mx+b)
-x+3y=9
add x to both sides
3y=x+9
divide by 3
y=1/3x+3
perpendicular lines have slopes that when multiplied, equal -1.
to find the slope (m) of our new line:
1/3m=-1
multiply by 3
m=-3
the slope of the new line is -3
here's our equation so far:
y=-3x+b
we need to find b (y intecept)
since the line passes through the point (-3,2), it should be a solution in the equation (plug it in, and the result is a true statement). We can also use it to find b
so, substitute the pointt into the equation:
2=-3(-3)+b
multiply
2=9+b
subtract
-7=b
so the equation of the line is y=-3x-7
Hope this helps!

Find RS 2x+15 3x+5 6x-37
Answer:2x+15+6x-37/2=3x+5
We move all terms to the left:
2x+15+6x-37/2-(3x+5)=0
We add all the numbers together, and all the variables
8x-(3x+5)+15-37/2=0
We get rid of parentheses
8x-3x-5+15-37/2=0
We multiply all the terms by the denominator
8x*2-3x*2-37-5*2+15*2=0
We add all the numbers together, and all the variables
8x*2-3x*2-17=0
Wy multiply elements
16x-6x-17=0
We add all the numbers together, and all the variables
10x-17=0
We move all terms containing x to the left, all other terms to the right
10x=17
x=17/10
x=1+7/10
The value of RS is 31.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If RS and UT are parallel, then their corresponding sides are proportional. Thus,
RS/UT = (2x + 15)/(6x - 37)
Now,
RS/UT = (2x + 15)/(6x - 37)
Cross-multiplying.
(2x + 15)UT = RS(6x - 37)
Expanding and simplifying.
2xUT + 15UT = 6xRS - 37RS
Rearranging.
6xRS - 2xUT = 15UT + 37RS
Factorizing.
2x(3RS - UT) = 15UT + 37RS
Dividing both sides by (3RS - UT):
2x = (15UT + 37RS)/(3RS - UT)
Substituting RS = 2x + 15 and UT = 6x - 37:
2x = (15(6x - 37) + 37(2x + 15))/(3(2x + 15) - (6x - 37))
Simplifying
2x = (90x - 555 + 74x + 555)/(6x + 36)
2x = (164x)/(6x + 36)
Multiplying both sides by (6x + 36):
12x² + 72x = 164x
Simplifying
12x² - 92x = 0
Factoring out 4x.
4x(3x - 23) = 0
So,
x = 0 or x = 23/3.
Since x cannot be 0 (as it would make UT = -37, (which is not possible),
x = 23/3.
Substituting this value of x into RS = 2x + 15.
RS = 2(23/3) + 15 = 31
Thus,
The value of RS is 31.

The outlier would be 28 because it is much lower than the rest of the numbers in the group and removing it would make the mean increase.
how do I determine the lower quartile and the upper quartile
Step-by-step explanation:
the lower quartile is the value of the middle of the first set of numbers, the upper quartile is the middle of the second set.
for example: 2 2 5 (7 )2 0 9
the seven is the median.
upper quartile would be the zero.
and lower quartile would be the second two.

A circular garden has a diameter of 10 yards. What is the area of the garden?
Use 3.14 for T.
Answer:
78.5 yards
Step-by-step explanation:
Essentially, to find the area of a circle simply use the equation pi r^2 (r=radius, or half of diameter). They also make it really easy by saying we may use 3.14 for pi, so really, we simply have to solve:
(3.14)5^2=78.5 yards

A person invests $2,730 in an account that earns 4.2% annual interest. Find when the value of the investment reaches $5,000. If necessary, round to the nearest tenth.
Step-by-step explanation:
You want to calculate the interest on $2730 at 4.2% interest per year after 5,000 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:P is the principal amount, $2730.00.
r is the interest rate, 4.2% per year, or in decimal form, 4.2/100=0.042.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 2730 × 0.042 × 5 to get that:
The interest is: $573.30
