Step-by-step explanation:
Head opposite angles.
b=60°
a=180-60=120°
Which of the following is NOT an arithmetic sequence?
a
1, 2, 3, 4,...
b
0.25, 0.5, 0.75, 1, ...
c
2, 2.5, 3, 3.5,...
d
-2, 4, -6, 8,...
Answer:
D
Step-by-step explanation:
To be an arithmetic sequence, the numbers have to be added or subtracted by a constant number. D is not the answer because -2+6 equals 4, but 4+6 doesn't equal -6, so D cannot be a arithmetic sequence.

Solve the system by substitution.
y=-x
-2x+5y=-28
Answer:
(4,-4)
x=4
y= -4
Step-by-step explanation:
We know that y is equal to and so we can plug the y value in for x into the other equation
-2x+5(-x)= -28
Solve for x
-2x-5x= -28
-7x= -28
x=4
Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y
y= -(4)
y= -4

The sum of 4 1/2 and what number is 12 5/7? Show your work
Answer:
Conversion a mixed number 4 1/

to a improper fraction: 4 1/2 = 4 1/
2
= 4 · 2 + 1/
2
= 8 + 1/

To find new numerator:
a) Multiply the whole number 4 by the denominator 2. Whole number 4 equally 4 * 2/
2
= 8/

b) Add the answer from previous step 8 to the numerator 1. New numerator is 8 + 1 = 9
c) Write a previous answer (new numerator 9) over the denominator 2.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 1) = 2. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 1 = 2. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - nine halfs plus twelve = thirty-three halfs.
Add: the result of step No. 2 + 5/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 7) = 14. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 7 = 14. In the next intermediate step the fraction result cannot be further simplified by canceling.

Step-by-step explanation:
The sum of 4[tex]\frac{1}{2}[/tex] and 8[tex]\frac{3}{14}[/tex] is 12[tex]\frac{5}{7}[/tex].
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Let the required number be n.
According to the question,
the sum of 4[tex]\frac{1}{2}[/tex] and n is equal to 12[tex]\frac{5}{7}[/tex].
In numeric form,
4[tex]\frac{1}{2}[/tex] + n = 12[tex]\frac{5}{7}[/tex]
Simplifying,
9/2 + n = 89/7
Substituting constant to term one side,
n = 89/7 - 9/2
n = 115/14
n = 8[tex]\frac{3}{14}[/tex]
Therefore, the number is 8[tex]\frac{3}{14}[/tex].

Jayla is a salesperson. She sold a guitar for $96 and earned 20% commission. How much
commission did jayla earn
Answer:
$115.20
Step-by-step explanation:
Hi! We need to find 1% of 96 to multiply by 20.
96 / 100 = .96
Now we multiply by 20.
20 x .96 = 19.2.
Now, we add 19.2 to what she earned in the first place (96).
19.2 + 96 = 115.20

I need to know the all the blanks including the equation on the bottom and y intercept and slopes
Answer:
See answers below
Step-by-step explanation:
Using the coordinates from the table (0, 12) and (1, 14)
m = 14-12/1-0
m = 2/0
m = 2
Hence the slope of the table is 2
y intercept occurs at x = 0
Substitute m = 2 and (0,12) into the equation y = mx+c
12 = 2(0) + b
12 = b
b = 12
Hence the y-intercept is 12
Get the equation
Recall that y = mx+c
y = 2x + 12
Hence the required equation is y = 2x+12

Harpreet gave her car for service at the service station and was charged as follows: a) 3.1 litres engine oil at the rate of rupees 210 per litre and VAT 20%. b) rupees 1105 for all other services and VAT 12.5%. c) rupees 1600 as labour charges and service tax 10%. find the bill amount.
Answer:Bill amount = 3,784.325 rupees.
Step-by-step explanation:
Calculating each service charge rendered to Harpreet, we have
a) 3.1 litres engine oil at the rate of rupees 210 per litre and VAT 20%
= 3.1 L X 210 rupees=651 rupees
VAT 20 % = 651 X 20%=130.2 Rupees
Charge on purchase of engine oil = 651 rupees + 130 .2 rupees=781.2 rupees
b) All other services = 1105
VAT 12.5% = 1105 X 12.5 %=138.125 Rupees
Charge on all other services = 1,105+ 138.125 rupees=1,243.125 rupees.
c.Labour charges = 1600
Service tax 10% = 1600 x10%=160
Charge on Labour = 1600+160=1760 rupees.
Bill amount = Total Charge on all services rendered at the station =781.2 rupees + 1,243.125 rupees + 1760 rupees= 3,784.325 rupees.

Hi can someone plaese finf the slope of this.
Answer:
5/2 is the slope
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
The rule for slope is rise/run. So you will rise from the point on (0, -3), all the way until you reach the same line as the other point, which is rising up 4. And then you would run to the point which is 2. rise/run = 4/2, therefore you divide to get 2. I hope this helps :)
