Each calendar will sell for $5 each write an equatio to model the total income for selling calendars

Brrunno [24]

To answer the question above, I let x be the number of calendars sold. You may use any other letter as this is just for representation. The total income generated in selling calendars is calculated by multiplying the number of calendars with the price. That is,
total income = 5x
If we let total income be y, our equation is further simplified into,
y = 5x

Write an expression to represent four more than the problem of three and a number z

kicyunya [14]

$Answer:$

If the "problem of 3 and a number $z$ " is multiplying: $4+(3z)$

If it's about adding: $4+(3+z)$

$Step-by-step$ $explanation:$

Scenario A: If it's 3 and z, then that means it's 3 $z$ , and we're adding 4, so it's $4+(3z)$ (make sure to put () around the 3 $z$ !)

Scenario B: If 3 and z is also 3+ $z$ , then the equation is $4+(3+z)$ (also use () on this too!)

How do I solve this one

just olya [345]

6/7Y - 18/28 =-15/14
First, let's get a common denominator
24/28Y - 18/28 =-30/28
Move your terms to isolate Y
24/28Y=-12/28
Multiply by 28 on both sides
24/Y=-12
Times both sides by Y, then divide by -12
24/-12=Y
Simplify
-2=Y

I hope this Helps!
