[tex] \frac{x}{7 + 2y} = 6[/tex]
[tex]x = 6(7 + 2y)[/tex]
Answer:
Given
x/7 + 2y = 6
Multiply through by 7 to clear the fraction
x + 14y = 42 ( subtract 14y from both sides )
x = 42 - 14y

Juliet is standing on the balcony 44 above the ground. She is looking at Romeo at an angle of depression of 6 degrees. if both star-crossed lovers were holding the end of a strong, what would the length of the string be?
Answer:
length of string ≈ 421 units (nearest whole number)
Step-by-step explanation:
Juliet is standing on the balcony 44 above the ground . The angle of depression is 6°. A string was held between Juliet and Romeo.
The illustration forms a right angle triangle. The hypotenuse of the triangle is the length of the string held by both star crossed lovers. The opposite side of the triangle is given as 44. Therefore,
using sin ratio
sin 6° = opposite/hypotenuse
sin 6° = 44/length of string
cross multiply
length of string sin 6° = 44
divide both sides by sin 6°
length of string = 44/sin 6°
length of string = 44/0.10452846326
length of string = 420.937978274
length of string ≈ 421 units(nearest whole number)
7) The senior classes at High School A and High School B planned separate trips to
Yellowstone National Park. The senior class at High School A rented and filled 2 vans
and 7 buses with 407 students. High School B rented and filled 1 van and 7 buses with
389 students. Every van had the same number of students in it as did the buses. How
many students can a van carry? How many students can a bus carry?
Answer:
Number of students in each van = 18
Number of students in each bus = 53
Step-by-step explanation:
Given: The senior class at High School A rented and filled 2 vans and 7 buses with 407 students.
High School B rented and filled 1 van and 7 buses with 389 students.
Also, every van and the van had the same number of students in it.
Solution:
Let x denotes number of students in each van and y denotes number of students in each bus.
According to the given information,
[tex]2x+7y=407\,\,\,(i)\\x+7y=389\,\,\, (ii)[/tex]
From (ii), put [tex]x=389-7y[/tex] in (i)
[tex]2(389-7y)+7y=407[/tex]
[tex]778-14y+7y=407\\778-407=7y\\7y=371\\y=\frac{371}{7}=53[/tex]
Put [tex]y=53[/tex] in [tex]x=389-7y[/tex]
[tex]x=389-7(53)\\=389-371\\=18[/tex]
Number of students in each van = 18
Number of students in each bus = 53

On a map of a town, a school is located at (–6, 2) and a movie theater is located at (–6, –15). What is the distance from the school to the theater on the map?
Answer:
13 units
Step-by-step explanation:
Since the x-coordinates are the same, you can simply add the absolute value of the y-coordinates.
|2 + (-15)|
or
|2 - 15|
= 13
Therefore, the distance from the school to theater is 14 units.
Answer:
13 units

What are the zeros of (fx) =x^2-10x+25
Answer:
Zero of the function f(x) is x = 5
Step-by-step explanation:
Given function is f(x) = x² - 10x + 25
For zeros or x-intercepts of this function,
Put f(x) = 0
x²- 10x + 25 = 0
x² - 2(5)x + 5² = 0
(x - 5)² = 0 [Since, a² - 2ab + b² = (a - b)²]
x = 5
Therefore, x = 5 will be the zero of the given function.
Tony need 16 inch long pieces of gold chain to make each 3 necklaces. He has a peice of chain that is 4 1/2 long. How much chain will he have left after making the necklaces
Answer: 6 inches of chain will he have left after making the necklaces
Step-by-step explanation:
There is a missing information. The correct question is:
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 1/2 feet long. How much chain will he have left after making the necklaces.
Solution
We would convert 4.5 feet to inches
1 foot = 12 inches
4.5 feet = 4.5 × 12 = 54 inches
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. It means that the number of the 16 inches pieces of gold chain that can be gotten to make each of 3 necklaces necklaces is 16 × 3 = 48
The length of chain left chain that will he have left after making the necklaces is
54 - 48 = 6 inches

At a summer camp,the ratio of campers to adults is kept equivalent to 7:1 use equivalent ratios to complete the table
Answer:
Campers: 7, 14, 28, 42
Adults: 1,2,5,30
Step-by-step explanation:
The tabular representation of the ratio of campers to adults in the summer camp is given as follows -
CAMPERS : 7 14 21 28 . . . . 7n
ADULTS : 1 2 3 4 . . . . n
We have a summer camp in which the ratio of campers to adults is kept equivalent to 7:1 .
We have to complete the table using the equivalent ratios.
How can you find out the equivalent ratios of the ratio a : b ?To find the equivalent ratios of a : b, follow the simple rule -
[tex]a:b=\frac{a}{b}=\frac{a\times2}{b\times2} =\frac{a\times3}{b\times3} =\frac{a\times4}{b\times4} = ... =\frac{a\times n}{b\times n}[/tex]
In the question given -
[tex]a:b=\frac{7}{1}=\frac{7\times2}{1\times2} =\frac{7\times3}{1\times3} =\frac{7\times4}{1\times4} = ... =\frac{7\times n}{n\times n}[/tex]
Hence, we can write the equivalent ratios in the form of tables -
CAMPERS : 7 14 21 28 . . . . 7n
ADULTS : 1 2 3 4 . . . . n

Find the length of the segment indicated. Round your answer to the nearest tenth if necessary.
Answer:
Length of x ⇒ ( About ) 11.5; Option C
Step-by-step explanation:
~ Let us plan this question step-by-step. We know that the line segment with length 13.1 is a radii to the circle, as well as a hypotenuse to a right triangle. Respectively the hypotenuse of another triangle is a hypotenuse as well. By radii ≅, these two part of these two triangles are ≅ ~
1. If these two parts are ≅, the triangle with leg x has a hypotenuse of 13.1 as well ( through ≅ ). This would mean that Pythagorean theorem is applicable for this triangle, as to solve for line segment x.
2. By Pythagorean Theorem ⇒
6.2^2 + x^2 = 13.1^2,
38.44 + x^2 = 171.61,
x^2 = 133.17
Length of x ⇒ ( About ) 11.5

Each brick is 13 inches long,5 inches wide,and 4 inches tall.of they used 11,700in3 of concrete how many Bricks did they make.
Answer:
45 bricks
Step-by-step explanation:
- With the knowledge of the 11,700 in^3 being used. We would need to have the measurements of the brick in that form as well. So in order to find the volume, we must multiply all sides. (13*5*4) = 260 in^3
- Now we have both numbers, we can just divide 11,700 by 260. This will give us 45. Meaning that 45 bricks are made.

Question: 5 ( x +20)= 7x +30
Answer:35
Simplifying
5(x + 20) = 7x + 30
Reorder the terms:
5(20 + x) = 7x + 30
(20 * 5 + x * 5) = 7x + 30
(100 + 5x) = 7x + 30
Reorder the terms:
100 + 5x = 30 + 7x
Solving
100 + 5x = 30 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
100 + 5x + -7x = 30 + 7x + -7x
Combine like terms: 5x + -7x = -2x
100 + -2x = 30 + 7x + -7x
Combine like terms: 7x + -7x = 0
100 + -2x = 30 + 0
100 + -2x = 30
Add '-100' to each side of the equation.
100 + -100 + -2x = 30 + -100
Combine like terms: 100 + -100 = 0
0 + -2x = 30 + -100
-2x = 30 + -100
Combine like terms: 30 + -100 = -70
-2x = -70
Divide each side by '-2'.
x = 35
Simplifying
x = 35
Hope it helps. Please tell me if im correct
Answer:
35
Step-by-step explanation:
5 * X= 5x
5* 20=100
these are for the ones inside the pararenthesis
so....
5x + 100= 7x+30
subtract 30 from both sides
5x+100-30= 7x-30-30
5x+70= 7x
now we need the variable on one side
so we subtract 5x on both sides
5x-5x+70= 7x-5x
70= 2x
now we divide by 2 on both to isolate the variable
70/2= 2/2
35=x
that's ur answer
hope this helped :D
