7n-4=31
7n=31-4
7n=27
n=27/7
:n=3
It’s equation and it’s really easy to solve
Well you can solve two step equations by multiplying or adding or subtracting or dividing by the number and put a n on the answer because there is only one n in equatioN see the solve the modle
<u>Final Answer:</u>
x = 20
<u>Step-by-step explanation:</u>
we'll be using the pythagorean theorem method, in this triangle the missing letter is a.
formula:
a = x
b = 21
c = 29
a =
a = (note: 29² = 29 × 29 = 841 and 21² = 21 × 21 = 441)
a =
a = 20
x = 20
Answer:
Step-by-step explanation:
Eqn. 1 ----> 4y = x
Eqn. 2 ----> 5x-10y = -50
(Simplifying eqn.2 further)
(Substituting the value of x from eqn. 1)
Now, substituting the value of y in eqn. 1 ,
I think it’s a loyalty marking program. I think it’s that because I feel like it’s the only answer that really makes sense bc the customer is being loyal to the service in order to receive their “reward”
