What does z equal in 4z+5=-3z-8

1 answer:

4 0

The first step to solve this equation is to move the variable to the left side of the equation and change its sign
4z + 3z + 5 = -8
Move the constant to the right side of the equation and change its sign
4z + 3z = -8 - 5
Collect the like terms on the left side of the equation
7z = -8 - 5
Calculate the difference
7z = -13
Lastly,, divide both sides of the equation by 7 to find out what z is
z = - $\frac{13}{7}$
This means that z in your equation is - $\frac{13}{7}$ ,, or 1 $\frac{6}{7}$ when simplified.

A company rents out 13 food booths and 27 game booths at the county fair. The fee for a food booth is $50 plus $6 per day. The f

Stella [2.4K]

Answer:

2000 + 321d

Step-by-step explanation:

It is stated that there are 13 food booths and 27 game booths.

The fee for a food booth is a flat 50 dollars. There are 13 food booths. SO

13 x 50 = 650 -----> This is one part of our expression.

Next, it is 6 dollars per day per food booth, and there are 13 food booths. SO

13 x 6d =78d (Note that it says that D can be used for the number of days)

Next, we need to solve for the game booths. A game booth also has a flat fee of 50 dollars. There are 27 of them.

50 x 27 = 1350 -----> This is the second part of our equation.

Next we need to calculate the amount per day per game booth.

9d x 27 = 243d. Putting all of these together, we get ---->

1350 + 650 + 243d + 78d

Adding all these up together, we get:

2000 + 321d

5x−3−7x = 15−x What is x?

Schach [20]

Simplify 5x-3-7 to -2x-3
-2x-3=15-x
Add 2x on both sides
−3=15−x+2x
Simplify 15-x+2x to 15+x
−3=15+x
Subtract 15 on both sides
-3-15=x
Simplify -3-15 to -18
-18=x
X=-18
