tell whether the angles are complementary or supplementary. Then find the value of x
Answer:
12) complementary, x=15
13) complementary, x = 35
x+ (x-20) = 90
x+x+20=90
2x=70
x=35
14) supplementary, x=31
2x+3x+25=180
5x=155
x=31
15) <1 = 130 degrees
<2 = 50 degrees
<3 = 130 degrees
16) x=53
x+2x+21=180
3x=159

Be sure to clearly label each part of your response as Part A, Part B, and Part C.
Part A: If the product of x and 3 is y, write an equation to represent the relationship between the two variables.
Part B: Explain your work in Part A.
Part C: Create a table of values to display five solutions to the equation. Write the solutions as ordered pairs.
Answer:
Part A: y = 3x
Part B: The relationship of y to x is y is 3 times as much as x.
Part C: (0,0), (1,3), (2,6), (3,9), (4,12)
Step-by-step explanation:
Part A: The product of x and 3 (3 times x) is (equals) y. So we can write this linear equation as y = 3x.
Part B: The linear equation is a representation of the relationship between y and x. Y is equivalent to three times x.
Part C: To create solutions to the linear equation, simply plug in a value of x to output a y.
x = 0 -> y = 3(0) = 0; (0,0)
x = 1 -> y = 3(1) = 3; (1,3)
x = 2 -> y = 3(2) = 6; (2,6)
x = 3 -> y = 3(3) = 9; (3,9)
x = 4 -> y = 3(4) = 12; (4, 12)

Michelle sells umbrellas. 2 9 of her umbrellas are blue, the rest are red. 5 11 of the red umbrellas have plastic covers. What fraction of the Michelle's red umbrellas that do not have plastic covers?
Answer: 14/33
Step-by-step explanation:
Since 2/9 of the umbrella are blue, the fraction for red umbrellas will be:
= 1 - 2/9
= 7/9
Since 5/11 of the red umbrellas have plastic covers. The fraction for those without plastic covers will be:
= 1 - 5/11
= 6/11
Therefore, the fraction of Michelle's red umbrellas that do not have plastic covers will be:
= 6/11 × 7/9
= 42/99
= 14/33

$725
$1,050
$1,375
75
H. p = 13c + 75
100
J. c = 13p + 75
Answer:
The answer is j
Step-by-step explanation:
The equations shows the relationship between c and p is p= 13c + 75.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have table which shows amount that a catering company charges based on the number of people at an event.
So, the equation that can framed from the table as
(y- 400)= (725- 400) / (50-25) . (x-25)
y- 400 = (325/ 25) (x-25)
y-400 = 13(x-25)
y-400 = 13x - 325
y = 13x - 325 + 400
y= 13x + 75
or p = 13c+ 75

In a polling station, there were 900 registered voters. During an election 10% of the registered voters did not cast their votes. The rest cast their votes to Ahmed, Babu and Chambuko in the ratio 3:2:1.If 30 votes were spoilt,how many votes did Ahmed get?
Answer:
Ahmed got 390 votes
Step-by-step explanation:
Here, we want to know the number of votes obtained by Ahmed
from the question, there were 900 registered voters
10% did not cast their votes
The number that didn’t cast their votes will be;
10% of 900
= 10/100 * 900 = 90
So the rest 90% casted and this value will be 900-90 = 810
810 people casted their votes
30 votes were spoilt;
The number of valid votes is thus;
810 - 30 = 780
Ahmed got a ratio of 3 in 3:2:1
The total value here is 3 + 2 + 1 = 6
So what Ahmed got will be;
3/6 * 780
= 780/2 = 390

Gustus bought three pairs of shoes. Each pair costs $19.98. What is the total amount he spent on shoes, before tax?
The total amount Gustus spent on shoes, before tax is $59.94.
Given that, Gustus bought three pairs of shoes. Each pair costs $19.98.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.
Now,
Total amount =Number of pairs of shoes ×Cost of one pair of shoe
= 3 ×19.98
= $59.94
Therefore, the total amount Gustus spent on shoes, before tax is $59.94.

George bought a model of a Viking ship for $68. If he paid
$5.10 in sales tax, what was the sales tax rate?
Answer:
We can convert 6.75% to a decimal by dividing by 100.
If x is the price of the house, then the sales tax is 0.0675x. The price of the house and the sales tax add up to $319,000.
x+0.0675x=319,000
Combe terms on the left.
1.0675x=319,000
