Answer:

12 months

Step-by-step explanation:

Given data

Gym A

charges $25 per month plus a $60 initiation fee

let the number of months be x

and the total charges be y

y= 60+25x---------------1

Gym B

charges $30 per month and no initiation fee

let the number of months be x

and the total charges be y

y=30x---------------2

Equate 1 and 2 above to find x

60+25x= 30x

collect like terms

60= 30x-25x

60= 5x

divide both sides by 5

x= 60/5

x= 12

Hence it will take 12 months

Explanation:

We can rewrite x^3y^2 into x*x^2*y^2

We can rewrite xy^5 into x*y^2*y^3

Note how x*x^2*y^2 and x*y^2*y^3 both have an x in common. So that means x is part of the GCF.

Similarly, x*x^2*y^2 and x*y^2*y^3 have y^2 in common as well.

Overall, both original expressions contain x and y^2 which leads to the overall GCF being xy^2

Answer:

5.9

Step-by-step explanation:

Area of a triangle is 1/2 base times height. the base is the horizontal part of the triangle and the height is the vertical part. Since it a isosceles they are equal. Those two segment are also called the legs (remember that for later). 4x4=16 times 1/2 equal 8 cm squared. So know me must find the hypotenuse. Since we since dealing with a right triangle we are going to use pythagorean theorem which is

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

where a and b are the LEGS and c is the hypotenuse. the legs are also known as base and height so we use

[tex] {4}^{2} + {4}^{2} = {c}^{2} [/tex]

which simplify to

[tex]16 + 16 = {c}^{2} [/tex]

[tex]32 = {c}^{2} [/tex]

[tex] \sqrt{32} [/tex]

which is about 5.9

Answer:

4x-5y=-10

Step-by-step explanation:

The standard form of a linear equation is Ax+By=CAx+By=C.

Multiply both sides by 55.

5y=5(45x+2)5y=5(45x+2)

Simplify 5(45x+2)5(45x+2).

Tap for more steps...

5y=4x+105y=4x+10

Rewrite the equation with the sides flipped.

4x+10=5y4x+10=5y

Move all terms containing variables to the left side of the equation.

4x−5y+10=04x-5y+10=0

Subtract 1010 from both sides of the equation.

4x−5y=−104x-5y=-10

Its 2 to 1. I just took the quizz!!!

Step-by-step explanation:

The ratio of fish to birds in the local pet shop is 2:1.

"Equivalent ratios are those that can be simplified or reduced to the same value. In other words, two ratios are considered equivalent if one can be expressed as a multiple of the other".

For the given situation,

Total number of pets in local pet shop = 42

Number of fish = 28, Then

Number of birds = [tex]42-28[/tex]

⇒ [tex]14[/tex]

Thus ratio of pets to fish = [tex]28:14[/tex]

Simplify the ratio to the smallest fraction

Dividing 14 on both sides,

⇒ [tex]2:1[/tex]

Hence we can conclude that the ratio of fish to birds in the local pet shop is 2:1.

Answer (assuming the equation can be written in point-slope form):

[tex]y-2 = -\frac{3}{2}(x+6)[/tex]

Step-by-step explanation:  

When knowing a point the line crosses through and its slope, you can write an equation in point-slope form, or [tex]y-y_1= m (x-x_1)[/tex].

1) First, find the slope of the line. Use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] and the x and y values of the two points given, then solve like so:

[tex]\frac{(-1)-(2)}{(-4)-(-6)}\\= \frac{-1-2}{-4+6}\\= \frac{-3}{2}[/tex]

Thus, the slope is [tex]-\frac{3}{2}[/tex].

2) Now, use point-slope form, [tex]y-y_1= m (x-x_1)[/tex]. Substitute the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.

The [tex]m[/tex] represents the slope, so substitute [tex]-\frac{3}{2}[/tex] in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line crosses through. Any of the two points will work, and I chose (-6,2) for this answer. So, substitute -6 for

[tex]y-(2)= -\frac{3}{2}(x-(-6)\\y-2 = -\frac{3}{2}(x+6)[/tex]

b) 1.25p+0.9≤7.5

c) 1.25p+0.9≥7.5

d) 1.25+0.9p≤7.5

Answer:

b) 1.25p+0.9≤7.5

Step-by-step explanation:

William has $7.50 to spend at the pretzel shop.

This means Williams can spend at least $7.50

A pretzel costs $1.25 and a soft drink costs $0.90. He buys one drink and ?pretzel

Therefore, the inequality can be used to find the number of pretzels William can buy is written as
