How do I find the value of z?

Mathematics
1 answer:
Shalnov [3]4 years ago

Hello!

The answer is z = 16..

Solve it like this..

#1) Regroup terms

-3 = -7+z/4 ---> -3 = z/4 - 7

#2) Add 7 to both sides.

-3 = z/4 - 7 ---> -3 + 7 = z/4

#3) Do the addition.

-3 + 7 = z/4 ---> 4 = z/4

#4) Multiply both sides by 4.

4 = z/4 ---> 4 * 4 = z.

#5) Do the multiplication.

4 * 4 = z ---> 16 = z

Hope this helps! ☺♥

Debnil has 6 teaspoons of salt. The ratio of teaspoons to tablespoons is 3:1. How many tablespoons of salt does Debnil have?
forsale [732]

Debnil have 2 tablespoons to salt.

Step-by-step explanation:

Given,

Number of teaspoons of salt = 6

Ratio of teaspoons to tablespoons = 3:1

Let,

x be the number of tablespoon of salt for 6 teaspoons.

Ratio of teaspoons to tablespoons = 6:x

Using proportion

Ratio of teaspoons to tablespoons :: Ratio of teaspoons to tablespoons

3:1::6:x

Product of mean = Product of extreme

6*1=3*x\\6=3x\\3x=6

Dividing both sides by 3

\frac{3x}{3}=\frac{6}{3}\\x=2

Debnil have 2 tablespoons to salt.

F(x) = |3x-4| give the domain and range
gulaghasi [49]

Answer:

Domain: -∞≤x≤∞

Range: 0≤F(x)≤∞

Step-by-step explanation:

The x variable can take any value.

In the case of F(x), the function only can take positive values, due to the absolute value function, and the function does not have any other restriction.

Whitepunk [10]

The answer would be 25 because all of the others are prime numbers, meaning they can only be divided by themselves and 1. So it would be C.

What is a number between 4.1 and 4.11? I got it wrong. I put 4.01...what did I do wrong???
Nesterboy [21]
So, 4.01 is less than 4.1. Think of it as 4.10 and 4.01, 1 is less than 10. One you could have put is 4.101, because it is more than 4.1 and less than 4.11
