Answer:
a (-3,16)
Step-by-step explanation:
This type of question is typically done by a trail and error method.
Putting values in a part in the given equation
16= -2×(-3)+10
16= 6+10
16=16
LHS=RHS
Hence the correct answer is a (-3,16)

Carri is trying to run a certain number of miles by the end of this month. If Carrie is 55% of the way to achieving her goal and she has already run 11 miles, how many miles is she trying to run by the end of this month
Answer:
20 miles
Step-by-step explanation:
Let
x = total number of miles she wish to run the end of this month
If Carrie is 55% of the way to achieving her goal and she has already run 11 miles
55% of her total miles = 11 miles
55% of x = 11 miles
55/100 * x = 11 miles
0.55x = 11
Divide both sides by 0.55
x = 11 / 0.55
= 20
x = 20 miles
x = total number of miles she wish to run the end of this month = 20 miles
She is trying to run 20 miles by the end of this month

Answer:
∠ JKL = 32°
Step-by-step explanation:
Since KN bisects ∠ LKM , then
∠ LKN = ∠ NKM = 35°
Thus
∠ JKL = ∠ JKM - ∠ LKN - ∠ NKM
= 102° - 35° - 35°
= 102° - 70°
= 32°
Having to do with quantities greater than zero A)positive B)negative C)Debt
Answer:
A)positive
Step-by-step explanation:
All quantities greater than zero will be positive, although zero itself is not considered negative or positive. Also, debt means that something would be owed. This would mean the number is negative and therefore not correct.

Guys please help I'm being timed
Answer:
C
Step-by-step explanation:
Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently.
Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.
Salesman C does not earn any commission. His weekly salary is $900.
On any given week, if Salesman B earns $1,020, how many sales did he have for the week?
sales
I will give brainlest
Answer:
18
Step-by-step explanation:
So base of 300/week.
We subtract 300 from 1020, leaving 720.
Divide 720 by 40 (because that is the amount per sale), we get 18.

A photograph of sides 35cm by 22cm is mounted onto a
frame of external dimension 45cm by 30cm. Find the area
of the border surrounding the photograph.
===================================================
Work Shown:
A = area of smaller rectangle
A = length*width
A = 35*22
A = 770
B = area of larger rectangle
B = length*width
B = 45*30
B = 1350
C = area of the border only
C = B - A
C = 1350-770
C = 580 square cm
Step-by-step explanation:
Dimension of photograph is 35cm and 22cm.
And external dimension of photo frame is 45cm and 30cm
So, the area of the border surrounding the photograph=Area of photo frame−Area of photo.
So, The area of the border surrounding the photograph=45×30−35×22
=1350−770=580cm

Line t has an equation of y = -1/2 x + 7. Line u is parallel to line t and passes through
(4, -6). What is the equation of line u?
Answer:
y = -1/2x - 4
Step-by-step explanation:
Let equation of line u be y = mx + c
since line t and line u are parallel, slope/gradient of both lines are the same (aka m = -1/2)
sub (4, -6):
-6 = -1/2(4) + c
c = -4
therefore, equation of line u is y = -1/2x - 4

You are tasked with buying pizza for a party that has 100 guests. 40 guests are children, and 60 guests are adults. Half of the children want pizza, and two thirds of the adults want pizza. Children will eat one slice of pizza, and adults will eat two slices of pizza. A pizza pie can be cut into 8 slices and costs $9 dollars per pie.
Total slices required for children,
[tex]C = \dfrac{40}{2}\times 1\\\\C = 20\ slices[/tex] .
Total slices required for adults,
[tex]A=\dfrac{2}{3}\times 60\times 2\\\\A = 80\ slices[/tex]
So, total slices required are, 20 + 80 = 100 .
Number of pizza, n = 100/8 = 12.5
So, he has to order 13 pizza cause pizza cannot be purchased in fraction.
Total price, P = 13 × 9 = $117 .
Hence, this is the required solution.
What is the value of x?
Answer:
x=84
Step-by-step explanation:
the sum of the angles in a pentagon is always 540 so do
540-131-108-107-110=84
Answer:
84
Step-by-step explanation:
The picture shown is 5 sided polygon
By using the formula (n - 2) * 180
We would get (5 - 2) * 180
3 * 180 = 540
We first add
131 + 108 + 107 + 110 + x = 456 + x
With the angle of the entire polygon, we would subtract which would give us the value for x
540 - 456 = 84

Write the equation of the line that goes through the point (1,3) & is
PARALLEL to the line y=2x+8 *
Answer:
y = 2x + 1
Step-by-step explanation:
Let the equation of the line be y = mx + c
since it is parallel to y = 2x + 8, their slope/gradient is the same (aka m = 2)
sub (1, 3):
3 = 2(1) + c
c = 1
therefore, the equation is y = 2x + 1
