Answer:
x= 95/2 or x=47.5 or 47 1/2
Step-by-step explanation:
3x + 10 = 5(x - 17)
First Step:
multiply and combine the right side (parentheses)
5 times x = 5x 5 times -17 = -85
3x + 10 = 5x -85
Second Step:
Add like terms ----> which is: 3x and 5x -----10 and -85
BUT since you only want one x on one side, you combine x first.
3x + 10 = 5x -85
-5x -5x
-2x + 10 = -85
NOW
Third Step: Add the integers---> 10 and -85
you want to get 10 on the same side as the -85, so you subtract it from BOTH sides.
which brings you:
-2x + 10 = -85
-10 -10
NOW that we've subtracted -10 from -85 it's technically just adding 85 and 10 then putting a negative sign on it.
so now we have:
-2x = -95
Step Four:
divide -2 from each side to get X alone
-2x = -95
-2 -2
ANSWER:
x=47.5

During swim practice Brand swim six butterfly stroke laps and eight freestyle Laps. What is the ratio of freestyle apps to total laps? A. 6:14 B. 8:6 C. 8:14 D. 14:8
Answer:
C) 8 : 14
Step-by-step explanation:
From the Question, we have
Six butterfly stroke laps
Eight freestyle Laps.
Total number of laps = (6 + 8)laps
= 14 laps
Hence,
The ratio of freestyle laps to total laps is:
Freestyle laps : Total laps
= 8 : 14
Option C is correct.

7. Triangles CDE and RST are similar triangles. What is
the length of side CD in triangle CDE?
R
40 ft.
32 ft.
20 ft.
T
S
Answer:
CD = 25 ft
Step-by-step explanation:
[tex] \triangle CDE \sim \triangle RST[/tex]
[tex]\therefore \frac{CD}{20}=\frac{40}{32}[/tex]
(Corresponding sides of similar triangles are in proportion)
[tex]\therefore \frac{CD}{20}=\frac{5}{4}[/tex]
[tex]\therefore CD = \frac{5}{\cancel 4}\times \cancel {20} \:\:\blue{\bold{5}} [/tex]
[tex]\therefore CD = 5\times 5[/tex]
[tex]\therefore CD = 25\: ft[/tex]
Answer:
CD = 25 ft
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{CD}{RS}[/tex] = [tex]\frac{CE}{RT}[/tex] , substitute values
[tex]\frac{CD}{20}[/tex] = [tex]\frac{40}{32}[/tex] ( cross- multiply )
32CD = 800 ( divide both sides by 32 )
CD = 25

What is the solution of x + 6 11
C. x –1
PLSS SHOW YOUR WORK PLSS
Answer: x < -1
Step-by-step explanation:
x + 6 < 5
x + 6 = 5
x = -1
x < -1
Now try to prove its correct
A number less than -1 is -2 so we'll try that.
x + 6 < 5
(-2) + 6 < 5
4 < 5
We can tell after substituting -2 for x, that the answer is correct
Oh and I changed the less than sign to an equal sign so it's easier to solve.

Jane paid $40 for an item after she received a 20% discount. Jane's friend says this means that the original price of the item was $48. a. How do you think Jane's friend arrived at this amount?
Answer:
The discount is $8
Step-by-step explanation:
Step one
Given data
Jane paid $40 for an item after she received a 20% discount.
Required
The initial cost of the item
Now in other to check whether Jane's friend is correct, let us solve for the initiai cost as follows
Let the initial cost be x
so
20% of 40
20/100*40
=0.2*40= $8
Therefore the discount is $8
hence the original price is
discount+ discounted sale(amount paid)
=8+40
=$48

A density graph for all the possible speeds between 0 mph and 320 mph is in the shape of a triangle. What is the height of the triangle?
A. 0.025
B. 0.0125
C. 0.003125
D. 0.00625
The height of the triangle is 0.00625.The correct option is D
To solve this problem
A density graph must have an area under it equal to 1. The range of speeds in this problem, 320-0 = 320, is the base of the density graph, which is shaped like a triangle. By multiplying the base by half of the triangle's height, we can determine the density graph's area.
Let h represent the triangle's height. The triangle's area is then:
1 = (1/2)320h
calculating h:
h = 1 / (320/2) = 0.00625
Therefore, option D is appropriate because the triangle's height is 0.00625.
