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

Mathematics
1 answer:
Mars2501 [29]3 years ago
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.

lara [203]

Answer:

18.75 packs of sugar

Step-by-step explanation:

20/8 = 2.5 (how many 8 ounce bottles in 20 oz)

2.5 * 30 = 75 (to find how many grams of sugar in the 20 oz bottle)

75/4 = 18.75 (how many packs of sugar it's equal to)

you can also use a ratio to solve:

8/30 = 20/x; cross multiply

600 = 8x; divide 8 on both sides

x = 75

75/4 = 18.74 (how many packs of sugar it's equal to)
