Answer: 18
Step-by-step explanation: The ratio 3:9 is equivalent to 1:3. This means that whatever number on the left side of the ratio should be multiplied by 3 to get the one on the right. 6 x 3 = 18.
The value of the unknown number for the fraction is equal to 18.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio is 3:9 then the value of the unknown number will be calculated as,
The ratio 3:9 is equivalent to 1:3. This means that whatever number is on the left side of the ratio should be multiplied by 3 to get the one on the right.
The unknown number will be,
6 x 3 = 18.
Therefore, the value of the unknown number for the fraction is equal to 18.

The difference of a number and eight is equal to 14.
"A number" means the unknown.
"Difference" means to subtract.
We already know two numbers, 8 and 14, but we don't know "A number."
We can put v as our variable. You can put any type of letter.
Therefore, the answer is: v - 8 = 14

Answer:
y = 5
Step-by-step explanation:
Perpendicular means forming a 90 degree angle. In y=5, the line is horizontal and only touches (0,5). When compared to the y-axis, they intersect at 90 degrees so it is y = 5
X+6-6x+10
(Combining like terms)
Answer:
Step-by-step explanation:
so you can always put a 1 infront of a stand alone x making 1x + 6 - 6x + 10
i also like to do a little trick were you can change the subtraction sign to an addition if you make what you subtraction negitive
so we have 1x + 6 + -6x + 10
we can add 6 and 10 and 1x and -6x make an end result of
-5x + 16
(or the other way since it is addition)
Gwendolyn placed a 10-foot ladder against the side of her house so that the base of the ladder was 3 feet from the base of the house, as shown in the diagram below. Which measurement in feet is closest to d, the distance from the top of the ladder to the ground?
Answer 9.5
you do the pyragtaham theory thing its A(squared) + B (squared) = C squared
you put the 3 at the A and you put the 10 at the C you sqaure them all up and then subtrct 9 from 100 and you get 91 and then you square root 91 and you get 9.5
The distance from the top of the ladder to the ground is 9.54 ft.
What is a right triangle?"It is a triangle whose one of the angle is 90°"
What is hypotenuse?"The longest side of the right triangle is called as hypotenuse."
What is Pythagoras theorem?"For a right triangle,
c² = a ² + b²,
where c = hypotenuse and a, b are other two sides of right triangle."
For given example,
Gwendolyn placed a ladder against the side of her house.
This means, it makes right triangle with ladder hypotenuse and base of the triangle is the distance between base of the ladder and the base of the house.
Let 'a' be the hypotenuse of triangle, 'b' be the base and 'd' be the distance from the top of the ladder to the ground
⇒ a = 3 ft. and b = 10 ft.
Using Pythagoras theorem,
⇒ b² = a² + d²
⇒ 10² = 3² + d²
⇒ 100 = 9 + d²
⇒ d² = 91
⇒ d = 9.54 ft.
Therefore, the distance from the top of the ladder to the ground is 9.54 ft.

In ΔJKL, k = 430 cm, l = 590 cm and ∠J=117°. Find the length of j, to the nearest centimeter.
Answer:
874
Step-by-step explanation:
The length of j from the given triangle JKL is 550 cm.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔJKL, k = 430 cm, l = 590 cm and ∠J=117°.
Using cosine rule
j²=k²+l²-2kl.cosJ
j²=430²+590²-2×430×590·cos117°
j²=184900+348100-507400×0.4539
j²=533000-230308.86
j²=302691.14
j=√302691.14
j=550 cm
Therefore, the length of j from the given triangle JKL is 550 cm.

A bag contains 21 coins consisting of nickles and dimes. The total value of the coins is $1.70.
Write a system of equations that models this situation. How many nickels are in the bag?
Answer:
8
Step-by-step explanation:
x = nickles
y = dimes
0.05x + 0.10y = 1.70
x + y = 21
y = 21 - x
0.05x + 0.10 (21 - x) = 1.70
0.05x - 0.10x + 2.10 = 1.70
-0.05x + 2.10 = 1.70
-0.05x = -0.40
x = 8
