Answer:
(1) x = -1 (1) y = 4
Step-by-step explanation:
r. (1) 5x - 3x = -5 + 3
2x = -2; x = -1
(1) 5y - 2[y - 3y +15] = 6
5y - 2y+6y - 30 = 6
9y = 36; y = 4

Samantha runs 3 miles every 2 days. How many days would it take her to run 24 miles
Answer:
16
Step-by-step explanation:
3 miles = 2 days
24 miles = ? days
24 / 3 = 8
8 x 2 = 16
Answer:
16 days
Step-by-step explanation:
[tex]\frac{3}{2}[/tex] to represent the relationship from miles to days
[tex]\frac{3}{2}[/tex]=[tex]\frac{24}{x}[/tex]
3 x 8 = 24
so do the same thing to 2
2 x 8 = 16 days
When 17 times a number is decreased by the square of the same number, the result is greater than 60. The
number must be between
Step-by-step explanation:
Let x be the number.
We have 17x - x² > 60.
=> x² - 17x + 60 < 0
=> (x - 5)(x - 12) < 0
=> 5 < x < 12
Hence the number is between 5 and 12, both non-inclusive.
The number must be between [tex]5[/tex] and [tex]12[/tex].
A square number is the result when a number has been multiplied by itself.
Let the number be [tex]x[/tex].
As [tex]17[/tex] times a number is decreased by the square of the same number, the result is greater than [tex]60[/tex],
[tex]17x-x^{2}>60[/tex]
[tex]x^{2} -17x+60<0[/tex]
[tex]x^{2}-12x-5x+60<0[/tex]
[tex]x(x-12)-5(x-12)<0[/tex]
[tex](x-5)(x-12)<0[/tex]
[tex]5<x<12[/tex]
So, the number must be between [tex]5[/tex] and [tex]12[/tex]

Step-by-step explanation:
1. Find the volume of a cube with a side of 9 cm.
2. Find the perimeter of a rectangle whose length is 4
cm and breadth is 3 cm.
3. Find the area of a square of side 11 m.
4. Find the area of a rectangle that is 14 m long and 5
m wide.
5. Find the perimeter of an equilateral triangle with
side 15 cm.
I'm in tension right now I am studying for exams and I'm tired it would be nice if you help me out!
Step-by-step explanation:
1. Given,
Side of the cube = 9 cm
Therefore, volume of the cube = side × side × side
= 9cm × 9cm × 9cm
[tex] = 729 {cm}^{3} (ans)[/tex]
2. Given,
Length of the rectangle = 4cm
Breadth of the rectangle = 3cm
Therefore, perimeter of the rectangle = 2(l+b)
= 2(4cm + 3cm) = 2 × 7cm = 14 cm (Ans)
3. Given,
Side of a square = 11 m
Therefore, area of the square = side × side
= 11 m × 11 m
[tex] \: = {121cm}^{2} (ans)[/tex]
4. Given,
Length of the rectangle = 14 m
Width of the rectangle = 5 m
Therefore, area of the rectangle = l × b
= 14 m × 5 m
[tex] = 70 {m}^{2} (ans)[/tex]
5. Given,
Side of the equilateral triangle = 15 cm
Therefore, perimeter of the triangle = 3 × side
= 3 × 15 cm = 45 cm (Ans)

Answer:
(5a²+4b³)³= 64b^9+240a^2b^6+300a^4b^3+125a^6
(2xy-1)³= 8x^3y^3−12x^2y^2+6xy−1
(3m-2n)= 0
(f+5)³= f^3+15f^2+75f+125
Step-by-step explanation:
(5a²+4b³)³ = [tex]64b^{9} + 240a^{2} b^{6} + 300a^{4} b^{3} + 125a^{6}[/tex]
(2xy-1)³ = [tex]8x^3y^3 - 12x^2y^2 + 6xy - 1[/tex]
(3m-2n) = 3m - 2n
(f+5)³ = [tex]f^3 + 15f^2 + 75f + 125[/tex]

Choose the missing step in the given solution to the inequality −2x − 14 > −4 + 3x.
−2x − 14 > −4 + 3x
−5x − 14 > −4
_____________
x < −2
A. −5x < 10
B. −5x > −18
C. −5x > 18
D. −5x > 10
Answer:
Step-by-step explanation:
-2x - 14 > -4 + 3x
subtract 3x from both sides
-5x - 14 > -4
add 14 to both sides
-5x > 10
divide both sides by -5
x < -2
The answer would be -5x > 10.
This is because our last inequality was -5x - 14 > -4 so we add 14 to both sides and it would look like this -5x (-14 + 14) > (-4 + 14) which would transition into our next inequality -5x > 10.
So therefore the answer would be -5x > 10.
