Answer:
x = -96/55
Step-by-step explanation:
Given that 2x + (5 /3)x + 7 = 3/5
Firstly, we have to multiply through out the expression by the common denominator. We can see that the denominators are 3 and 5, hence the common denominator is 15. Multiplying through by 15 gives:
2x * 15 + (5 /3)x * 15 + 7 * 15 = (3/5) * 15
30x + 25x + 105 = 9
Collect like terms:
30x + 25x = 9 - 105
55x = -96
Dividing through by 55:
x = -96/55

Jordon missed 49 on his multiple choice math final and earned a grade of 65%. How many total questions were on the final exam?
Answer:
The exam was out of 75.
Step-by-step explanation:
You know that he earned 65% so more than half his answers were correct.
Then, you would guess and check try 49/60, 49/70, and go up by 10s or 5s. You will then realize that 49÷75 equals 65.333. This rounds up to 65.

Maria is making a fruit punch. There are 15.75 ounces of orange juice in a container. Maria pours 2.25 ounces of cranberry juice into the container each second. How many ounces of fruit punch are in the container after 9 seconds?
Answer:
20.25 ounces
Step-by-step explanation:
We are given 2.25 ounces of cranberry poured into the container per second. We need to find is how much that is after 9 seconds. (Note: This is different from the 15.75 ounces of orange.) There are many ways to solve this question (e.g If 2.25 is 1, then multiply 2.25 and 9 = 20.25) Now to solve this let's set up fractions; let "x" be the variable;
[tex]\frac{1}{2.25}=\frac{9}{x}[/tex]
Apply fraction: if [tex]\frac{a}{b}=\frac{c}{d}\mathrm[/tex] then [tex]a\cdot \:d=b\cdot \:c[/tex] (meaning cross multiply)
[tex]1\cdot \:x=2.25\cdot \:9[/tex]
Simplify
Multiply by 1[tex]1 x = 2 . 2 5 \cdot 9 \\\\ x = 2 . 2 5 \cdot 9[/tex]
Multiply the numbers[tex]x = 2 . 2 5 \cdot 9\\\\x=20.25[/tex]
Therefore, there are 20.25 ounces of fruit pouch in the container after 9 seconds.

A class of 30 swim team members took a lifesaving test. Eighteen of the members had an average score of 92 points. The remaining members had an average score of 84 points.
What was the average for the entire swim team?
Answer:
88.8%
Step-by-step explanation:
1.) 30-18= 12 which is the number of member that had an average of 84
2.)Then multiply 12 times 84 = 1008
3.) You multiply 18 by 92 which equals 1656
4.)Add 1008 and 1656 together and get 2664.
5.)Divide 2664 / 30 and you get the average of 88.8

The equations have the same solution because the second equation can be obtained by multiplying both sides of the first equation by −3. C. The equations have the same solution because the second equation can be obtained by multiplying both sides of the first equation by 3. D. The equations have the same solution because the second equation can be obtained by multiplying both sides of the first equation by −4.
Calculate the surface area of an open cylinder measuring 35cm in diameter and 60cm high.
Answer:
6598.2 in^2
Step-by-step explanation:
Given data
Diameter= 35in
Radius= d/2= 35/2= 17.5in
Height = 60cm
The expression for the curve surface area of a cylinder is
CSA=2πrh
substitute
CSA= 2*3.142*17.5*60
CSA= 6598.2 in^2
Hence the CSA is 6598.2 in^2
if each box represents 1 miles, what is the shortest distance from the school to the skate park.
The shortest distance between two points is a straight line.
Use the distance formula for points.
In the diagram, we are given two points:
(4,2) and (-3,0).
Let d = distance between the two points.
d = sqrt{(-3 -4)^2 + (0-2)^2}
d = sqrt{(-7)^2 + (-2)^2}
d = sqrt{49 + 4}
d = sqrt{53}
d = 2.2360679775
d = 2.2 miles
Plot two points that are 888 units from Point \blueD{B}Bstart color #11accd, B, end color #11accd and also share the same xxx-coordinate as Point \blueD{B}B
Question:
Plot two points that are 8 units from Point B and also share the same x-coordinate as Point B
See attachment for grid
Answer:
See attachment for plot
Step-by-step explanation:
See comment for complete question
From the attached image, we have:
[tex]B = (-6,0)[/tex]
Required
2 points that are 8 units away and on the same x coordinate
Let the two points be [tex]C\ and\ D[/tex]
The first condition is that; C and D must be on the same x coordinate as B.
So, we have:
C = (-6,_)
D = (-6,_)
8 units from B implies that we add or subtract 8 from the y coordinate of B.
So, we have:
[tex]C = (-6,0+8)[/tex]
[tex]D = (-6,0-8)[/tex]
[tex]C= (-6,8)[/tex]
[tex]D= (-6,-8)[/tex]

Find the radius of a circle whose area is 576π m²
Answer:
r = 24 m
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here A = 576π , then
πr² = 576π ( divide both sides by π )
r² = 576 ( take the square root of both sides )
r = [tex]\sqrt{576}[/tex] = 24

Answer:
27.6 is the area
Step-by-step explanation:
Area of the given triangle is equals to [tex]27.6 in^{2}[/tex](round to nearest tenth).
What is triangle?" Triangle is defined as two dimensional geometrical shape with three vertices, three sides and three angles enclosed in it."
Formula used
Pythagoras theorem
(Hypotenuse)² = (Base)² + (Height)²
Area of a right triangle = [tex]\frac{1}{2} \times b\times h[/tex]
[tex]b[/tex] represents the base of the triangle
[tex]h[/tex] represents the height of the triangle
According to the question,
In a given triangle,
Hypotenuse [tex]= 11in[/tex]
Height [tex]= 6in[/tex]
Substitute the value in Pythagoras theorem to get the measure of base,
[tex](11)^{2} = b^{2} + 6^{2}\\\\\implies b^{2}= 121 -36\\\\\implies b =\sqrt{85}[/tex]
Substitute the value in the formula to find area of a triangle,
Area of a triangle [tex]= \frac{1}{2}\times \sqrt{85} \times 6[/tex]
[tex]= \frac{1}{2} \times 9.22 \times 6\\\\= 9.22 \times 3\\\\= 27.66[/tex]
≈ [tex]27.6in^{2}[/tex] ( round to nearest tenth)
Hence, area of the given triangle is equals to [tex]27.6 in^{2}[/tex](round to nearest tenth).
