Step 1: Cross-multiply.
15 /x = 5 /6
(15)*(6)=5*x
90=5x
Step 2: Flip the equation.
5x=90
Step 3: Divide both sides by 5.
5x /5 = 90 /5

(9x + 5) - (4x + 3)
Please show work
Answer:
Step-by-step explanation:
Simplifying
(9x + 5) + -1(4x + 3) = 0
Reorder the terms:
(5 + 9x) + -1(4x + 3) = 0
Remove parenthesis around (5 + 9x)
5 + 9x + -1(4x + 3) = 0
Reorder the terms:
5 + 9x + -1(3 + 4x) = 0
5 + 9x + (3 * -1 + 4x * -1) = 0
5 + 9x + (-3 + -4x) = 0
Reorder the terms:
5 + -3 + 9x + -4x = 0
Combine like terms: 5 + -3 = 2
2 + 9x + -4x = 0
Combine like terms: 9x + -4x = 5x
2 + 5x = 0
Solving
2 + 5x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2' to each side of the equation.
2 + -2 + 5x = 0 + -2
Combine like terms: 2 + -2 = 0
0 + 5x = 0 + -2
5x = 0 + -2
Combine like terms: 0 + -2 = -2
5x = -2
Divide each side by '5'.
x = -0.4
Simplifying
x = -0.4

John jogged 4.5 miles on Thursday, 7 2/5 miles on Friday, and 10.4 miles on Saturday. How many miles does John have to run in order to run 25 miles for the week
im giving 20 points
Answer:
2.7 miles
Step-by-step explanation:
25 - 10.4 - 4.5 - 7 2/5 will give you 2.7
Answer:
8 miles
Step-by-step explanation:
If we divide 70 by 50, we get the unit rate for the ratio 70 minutes for every 50 miles.
70÷50=1.4
So the runner is running 1.4 minutes per mile. We can multiply this unit rate by the number of miles:
1.4 minutes mile × 5 miles = 7 minutes
Thus it will take her 7 minutes to run 5 miles at this pace.
If it takes her 7 minutes to run 5 miles, it will take her 7÷5 = 1.4 minutes to run 6÷3=2 miles at the same pace.
If it takes her 1.4 minutes to run 5 miles, it will take her 1.4×5=7 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.
We found her pace in minutes per miles in part (a).

Maria and laurie are making orange juice.Maria use 2 cups of concentrate and 5 cups of water. Laurie uses 3 cups of concentrate and 7 cups of water . Whose mix would be the strongest? Why?
Answer:
Step-by-step explanation:
To obtain the strongest mix :
Maria:
2 cups of concentrate ; 5 cups of water
Ratio = 2/5 = 0.4 concentrate per 1 cup of water
Laurie:
3 cups of concentrate ; 7 cups of water
Ratio = 3/7 = 0.4285714 concentrate per 1 cup of water
0.4285714 > 0.4
Hence, Laurie's mix is the strongest as it has higher concentrate per cup of water.
Arlene has raised $56 for her class field trip. This is $14
more than three times the amount Adam has raised.
Which equation could you use to find how much money
Adam has raised?
Assuming Adams amount is x, three times his amount will be 3x. $14 more than the times Adam's amount will be 14 +3x.
Therefore if Arlene's money is $56 which is $14 more than three times Adam's amount, then the equation will be ;
14+3x=56

Step-by-step explanation:
Divide 2x^4+3x^3-5x+6 by x^2+3x-2 .
2x^4 + 3x^3 - 5x + 6 ÷ x^2 + 3x - 2
= 2x^6 + 3x^5 − 2x^3 − 2x^2 + 6/ x^2
the two angles measuring (30 + 2 a)degree and (125 -a) degree supplementary to each other, then find the value of a.
Answer:
The value of a is 25
Step-by-step explanation:
When two angles are supplementary, they add up to 180 degrees
Mathematically,
(30 + 2a) + (125-a) = 180
30 + 2a + 125 - a = 180
a + 155 = 180
a = 180-155
a = 25 degrees

What is the length of DE in the image provided? (Please explain so I can understand in the future)
A. DE=4
B. DE=5
C. DE=6
D. DE=7
==========================================================
Explanation:
We have these three facts:
The arc markings on angles C and D indicate those angles are congruent. We can say that angle ACB = angle EDB.Another pair of congruent angles are angle ABC and angle EBD. These are vertical angles. Lastly, we have a pair of congruent sides AB and BE because of the tickmarks.Those three facts allow us to use the AAS (angle angle side) congruence theorem to prove that triangle ABC is congruent to triangle EBD.
Then by CPCTC (corresponding parts of congruent triangles are congruent), we know that AC = DE. Note how 'A' and 'C' are the first and last letters of ABC; similarly, 'E' and 'D' are the first and last letters of EBD. Segment ED is the same as segment DE.
So to find the length of DE, we need to find the length of AC. To do that, we need the value of x.
----------------
Recall earlier that AB = BE. Use this to find x
AB = BE
1.5x = 3x-6
1.5x-3x = -6
-1.5x = -6
x = -6/(-1.5)
x = 4
Now we can find the length of AC
AC = x+3
AC = 4+3
AC = 7
This must mean DE = 7 as well.
Answer:
DE=7

Emily is encouraged to read more than 4 hours each week. It takes her 45 minutes to finish her first book. She divides the remainder of the time equally amongst the other six days. What is the minimum number of minutes she should read each day?
A. x > 32.5 minutes
B. x > 40 minutes
C. x \leq 32.5 minutes
D. x[\leq 40 minutes
Answer: D
Step-by-step explanation:
40+40= 1 hour 20 min
40+40= 1 hour 20 min
40+40 = 1 hour 20 min
40————-> 40 min
Add all together you get 4 hours in one week

Find all x-intercepts of the following function. Write your answer or answers as coordinate points. Be sure to select the appropriate number of x-intercepts.
Answer:
(- 3, 0 ), (4, 0 )
Step-by-step explanation:
To find the x- intercepts let f(x) = 0
[tex]\frac{x^2-x-12}{5x^2+ 4x}[/tex] = 0
The denominator cannot equal zero as this would make f(x) undefined.
Equate the numerator to zero and solve for x
x² - x - 12 = 0 ← in standard form
(x - 4)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
x- intercepts are (- 3, 0 ) and (4, 0 )
Please answer correctly !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!
Answer:
VA
Step-by-step explanation:
Angle VYA = 180-94-46 = 40 degrees.
Know that the side length opposite the smallest angle has the smallest length.
VY and VA are the two smallest, but 40 < 46, therefore VA is the shortest length.
Short (and not very rigorous) proof:
The law of sines says that sinA/a = sinB/b = sinC/c, where x is the side opposite the angle X
sin46/YV = sin40/VA
sin46 > sin40, therefore YV > VA.
