Find the rule. Solve for n. Х 12 15 20 Y 7 10 15 17 n Rule:
Answer:
n =22
Step-by-step explanation:
12-5=7
15-5=10
20-5=15
n-5=17
collect like terms
n=17+5
n=22
Answer:
Looking at the rule we can see that our x value is always 5 more than our y value. So to get our n we just take the y value of 17 and add 5 and we get 22. So our n is equal to 22.

if y varies directly as x, and y = 3 when x = 9, how will you find x when y = 36?
Answer:
(Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.

a triangle has an area of 63 square inches. if the height s 9 inches. what is the length of the base
Answer:
14 = b or b = 14
Step-by-step explanation:
Area of a triangle: 1/2*b*h
Area = 1/2*b*h
63 = 1/2*b*9
63 = 9/2b
2(63 = 9/2b)
126 = 9b
/9 /9
14 = b or b = 14
Check:
63 = 1/2*b*9
63 = 1/2*14*9
63 = 7 * 9
63 = 63

Answer:
givenvertical angle congruenceAA similarity theoremStep-by-step explanation:
1. ∠C ≅ ∠E . . . . given
2. ∠ABC ≅ ∠DBE . . . . vertical angle congruence theorem
3. ΔABC ~ ΔDBE . . . . AA similarity theorem
_____
When showing similarity of triangles with no marked sides, theorems that involve sides (SSS, SAS, AAS) do not apply. The only theorem you can invoke is the AA similarity theorem.
A proof generally begins by restating those things that are "given," that form the basis for the rest of the proof. Here, the arcs on the diagram show that angles C and E are congruent. That is "given."
What is the first step in solving the equation? 7 (x - 3) = 15+ x
a. Distribute by multiplying 7 by the terms in the parentheses
b. Multiply by 7 on both sides of the equation
c. Add 3 to both sides of the equation
d. Subtract x from both sides of the equation
Answer:
The first step is A, distributing and multiplying 7 to the x and -3 in the parentheses
Step-by-step explanation:
It’s kind of hard to offer and explanation for this, so sry!
(Please award brainliest if possible!)
Answer:
(a).
Step-by-step explanation:
7 is outside the parentheses and needs to be distributed to x and -3 before trying to isolate the x.
Jessica uses a food delivery service to order dinner. She paid $27.44 for dinner, which included the cost of the food and a delivery
fee, which was 12% of the cost of the food
What was the cost of Jessica's dinner before the delivery fee?
Enter your answer in the box
Answer:
3.29
Step-by-step explanation:
Turn 12% to 0.12.
Multiply 27.44 times 0.12.
Answer:
$24.50
Step-by-step explanation:
Total cost = food cost + (food cost x 12%)
27.44 = x + (x • 0.12)
(rearrange and distribute)
1x + 0.12x = 27.44
(solve for x)
1.12x = 27.44
x = 27.44 / 1.12 = 24.50
Original food cost is $24.50

2) Father earns Rs 21,600 in a month. He spends 15% of his earning on the education of his children and 25% on food. a (i) Find his total expense on education and food. (ii) How much does he save in a month ? (iii) How much does he save in 1 year ? (iv) If he spends 80% of his annual saving to buy a piece of land, What is the cost of the land ?
Answer:
a) i) Rs 8,640
ii) Rs 12,960
iii) Rs 155,520
iv) Rs 124,416
Step-by-step explanation:
Salary = Rs 21,600 per month
a) i)
Percentage of salary spent on education = 15%
⇒ 15% of 21600 = 0.15 x 21600 = 3240
Percentage of salary spent on food = 25%
⇒ 25% of 21600 = 0.25 x 21600 = 5400
Therefore, total monthly expenses = 3240 + 5400 = 8640
ii) Monthly savings = monthly salary - monthly expenses
= 21600 - 8640
= 12960
iii) 1 year savings = monthly savings x 12
= 12960 x 12
= 155520
iv) 80% of savings = 0.8 x 155520 = 124416
Last tuesday evening, Aaron, the car wash owner, found he had 90% more quarters than dimes. If the combined value of Aaron's quarters and dimes is $69, how many times did he have
Aaron the car wash owner had 228 quarters and 120 dimes.
EquationAn equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the number of quarters and y represent the number of dimes. Hence:
x = 90% of y + y
x = (0.9y) + y
x - 1.9y = 0 (1)
Also:
0.25x + 0.1y = 69 (2)
From both equations:
x = 228, y = 120
Aaron the car wash owner had 228 quarters and 120 dimes.
