Answer:
a) 720°
b) 98
Step-by-step explanation:
a) The sum of interior angles of an n-gon is (n-2)×180°. For n=6, the sum is ...
(6 -2)×180° = 4×180° = 720°
__
b) The sum of the marked angles is 622°, so the value of x is ...
x = 720 -622
x = 98

Answer:
y = 1 3 x + 13 3
Step-by-step explanation:
The equation of the line is
y = 1 3 x + 13 3
. To find other points on the line, simply plug in an x value, and solve for the corresponding y value.
Explanation:
To find other points on the line, we first have to find the equation for the line. We can easily use point-slope form:
y − y 1 = m ( x − x 1 )
y − 5 = 1 3 ( x 2 )
To put it in slope-intercept form, isolate y and simplify:
y= 1 3 ( x − 2 ) + 5
y = 1 3 x − 23 + 5
y = 1 3 x + 13 3

Hank bought 3 more boxes of cereal than gallons of milk. He bought x boxes of cereal at $2.79 each. Each gallon of milk costs $4.49. Consider the expression 2.79x + 4.49 (x-3).
A. The term x- 3 represents the number of gallons of milk.
B. The coefficient 2.79 represents the cost of one box of cereal.
C. The expression represents the total number of boxes of cereal and gallons of milk.
Answers
Answer: all statements are true.
Step-to-step explanation:
Given: Cost of 1 box of cereal =$2.79
Cost of x boxes of cereal= $2.79 x
Each gallon of milk costs $4.49.
Hank bought 3 more boxes of cereal than gallons of milk.
gallons of milk = x-3
Total cost = (cost per box of cereal) × (x) +(Cost per gallon of milk) × (x-3)
= 2.79x + 4.49 (x-3)
All statements are correct:
A. The term x- 3 represents the number of gallons of milk.
B. The coefficient 2.79 represents the cost of one box of cereal.
C. The expression represents the total number of boxes of cereal and gallons of milk.
If "u" varies directly with "v", and u = 6 when v = -7, what is "u" when v =4?
Answers
Answer:
u = -24/7
Step-by-step explanation:
u = 6 = u
v -7 4
-7u = 24
u = -24/7
Answer:
u = - [tex]\frac{24}{7}[/tex]
Step-by-step explanation:
Given that u varies directly with v then the equation relating them is
u = kv ← k is the constant of variation
To find k use the condition u = 6 when v = - 7, then
6 = - 7k ( divide both sides by - 7 )
- [tex]\frac{6}{7}[/tex] = k
u = - [tex]\frac{6}{7}[/tex] v ← equation of variation
When v = 4 , then
u = - [tex]\frac{6}{7}[/tex] × 4 = - [tex]\frac{24}{7}[/tex]

6x-1=-x+9
Answers
Answer:
x=10/7
Let's solve your equation step-by-step
6x−1=−x+9
Step 1: Add x to both sides
6x−1+x=−x+9+x
7x−1=9
Step 2: Add 1 to both sides
7x−1+1=9+1
7x=10
Step 3: Divide both sides by 7
7x/7=10/7
x=10/7
Answer:
x = 10 / 7
Step-by-step explanation:
6x - 1 = -x + 9
Add 1 to both sides of the equation.
6x - 1 = -x + 9
6x - 1 + 1 = -x + 9 + 1
Simplify
Add the numbers
6x - 1 + 1 = -x + 9 + 1
6x = -x + 9 + 1
Add the numbers
6x = -x + 9 + 1
6x = -x + 10
Add x to both sides of the equation.
6x = -x + 10
6x + x = -x + 10 + x
Simplify
Combine like terms
6x + x = -x + 10 + x
7x = -x + 10 + x
Combine like terms
7x = -x + 10 + x
7x = 10
Divide both sides of the equation by the same term
7x = 10
7x/7 = 10/7
Simplify
Cancel terms that are in both the numerator and denominator.
7x/7 = 10/7
x = 10/7
Solution
x = 10/7

Answer:
Pumpkins pounds and weight
Step-by-step explanation:
Answer: Percy decided to weigh different numbers of pumpkins to find their weights. He put his findings in the table above (in he question) . He found a pattern in his findings, so he used it to find how many 50 pumpkins will weigh. Can you tell me what answer he got?
Step-by-step explanation:
Since every 5 pumpkins is 8 pounds, we just need to divide 50 by 5, and times that number by 8 pounds to find the answer.
50/5 is 10.
10 x 8 = 80
Or, since 25 are 50 pounds, and 25 +25 = 50, you ad 40 to 40, giving you the answer 80.
The answer to my word problem is 80.
Decrease £313 by 62%
Give your answer rounded to 2 DP.
Answers
Answer:
194.06
Step-by-step explanation:
£313 decreased by 62% is £118.94
In order to determine the answer, the first step to take is to determine the value of 62% of £313.
Value of 62% = 62% x £313
0.62 x £313 = £194.06
The second step is to subtract the value of 62% of £313 from £313
£313 - £194.06 = £118.94
In order to decrease £313 by 62%, the first step is to determine the value of 62% of £313 and then subtract the value gotten from the previous step from £313.

Economics is the research of how people allocate limited resources for generation, circulation, and consumption, both personally and collectively.
Two significant types of economics are microeconomics, which concentrates on the performance of individual customers and generators, and macroeconomics, which measures overall economies on a local, nationwide, or global scale.
Economics is especially concerned with performance in generation and exchange and practices models and opinions to assume how to generate incentives and procedures that will maximize productivity.
