Step-by-step explanation:
At a local gym you go to, you either pay $90 fee for a monthly pass, and an additional $4 for each time you decide to go to the gym, or you can pay $13 each time you go to the gym. Write and solve a system of equations for this situation to determine how many times you have to go to the gym in order for it to cost the same amount
A. 90
В. 130
C. 10
D. 5
Answer: C. 10.
Step-by-step explanation:
Let x = Number of times you have to go to the gym in order for it to cost the same amount.
Given: Monthly pass fee = $90
Additional charge = $4
Total amount = (Monthly fee) + (Number of times) (Additional charge)
Total amount = 90+4x (i)
Payment for each time you go to the gym = $13
Total amount = 13x (ii)
From (i) and (ii) , we get
[tex]13x=90+4x\\\\\Rightarrow\ 13x-4x=90\\\\\Rightarrow\ 9x=90\\\\\Rightarrow\ x=\dfrac{90}{9}\\\\ \Rightarrow\ x= 10[/tex]
Hence, the number of times you have to go to the gym in order for it to cost the same amount= 10
Hence, the correct option is C. 10.

2x + 4y = 8
10x – 4y = 16
Answer:
x=2, y=1
Step-by-step explanation:
Add:
2x+4y=8
+10x-4y=16
------------------
12x=24
Divide by 12 on both sides:
x=2
Substitute x with 2 on either 2x+4y=8 or 10x-4y=16 it doesn't matter it will result in the same answer.
(I will do both of them to prove it but you only need to replace x with one of the equation)
For 2x+4y=8
2(2)+4y=8
4+4y=8
Subtract 4 on both sides
-4+4+4y=8-4
4y=4
Divide 4 on both sides:
y=1
For 10x-4y=16
10(2)-4y=16
20-4y=16
-20+20-4y=16-20
-4y=-4
Divide -4 on both sides:
y=1
The answer for both 2x + 4y = 8 and 10x – 4y = 16 are the same showing that it doesn't matter which equation you replace the number with it will still result you in the same answer
Hope this helps!
What is Which equation correctly demonstrates the Distributive Property? F. $a\left(b+c\right)=ab+c$ G. $a\left(b+c\right)=ab+ac$ H. $a+\left(b+c\right)=\left(a+b\right)+\left(a+c\right)$ I. $a+\left(b+c\right)=\left(a+b\right)\cdot\left(a+c\right)$
Answer:
[tex]G.\ $a\left(b+c\right)=ab+ac$[/tex]
Step-by-step explanation:
Given
[tex]F.\ $a\left(b+c\right)=ab+c$[/tex]
[tex]G.\ $a\left(b+c\right)=ab+ac$[/tex]
[tex]H.\ $a+\left(b+c\right)=\left(a+b\right)+\left(a+c\right)$[/tex]
[tex]I.\ $a+\left(b+c\right)=\left(a+b\right)\cdot\left(a+c\right)$[/tex]
Required
Which of the options shows Distributive Property
Distributive property states that
For: [tex]a(b + c)[/tex]
The equivalent is: [tex]ab + ac[/tex]
In other words:
[tex]a(b + c) = ab + ac[/tex] ----- (1)
Having mentioned that;
Next, we compare the list of given options to (1) above
Option G matches (1).
[tex]G.\ $a\left(b+c\right)=ab+ac$[/tex]
Hence, option G correctly demonstrates distributive property

The distance around a lake is 6 7/12 kilometers. Evan rode his bike 5/6 of the distance around the lake. What is the distance in kilometers that Evan rode
Answer:
5 35/72 kilometers
Step-by-step explanation:
The distance around a lake is 6 7/12 kilometers. Evan rode his bike 5/6 of the distance around the lake. What is the distance in kilometers that Evan rode
This is calculated as:
Total distance = 6 7/12 km
Evan rode = 5/6 of the distance
Hence:
The distance Evans rode is
5/6 of 6 7/12
= 5/6 × 79/12
= 395/72
= 5 35/72 km(kilometers)

Answer:
you have to use the Pythagorean theorem. a^2 + b^2= c^2
72^2 + b^2 = 75^2
5184 + b^2 = 5625 (subtract 5184 from both sides)
b^2= 441 (find the square root of each side)
b= 21
What is the equation of the line that passes through the point (3,-5) and has a
slope of o?
Answer:
y = -5
Step-by-step explanation:
slope of 0 means m = 0 in y intercept form y = mx + b.
they have given you (3, -5), plug these in and solve for your equation.
remember, a line that has a 0 slope means it is a horizontal line.
y = mx + b
-5 = 0(3) + b
-5 = b
so you have, y = -5.
