X+x-z; use x=3 & z=4​

Mathematics
1 answer:
nadezda [96]3 years ago
6 0

Answer:

2

Step-by-step explanation:

Order of operations is not as applicable in this situation because we're just dealing with addition and subtraction.  This is a simple case of plugging in values for the given expression.

x = 3

z = 4

So it becomes...

3 + 3 - 4

6 - 4

2

So with the given expression of x + x - z and the given values of x = 3 and z = 4, the expression should sum to: 2

a particular submarine is 12 m long. A model of it was built with a scale of 1 cm: 3 m. How long is the model? Show all work.
slamgirl [31]
1cm : 3m

to get from 12m to 3m you have to divide by 4, so if:

3 x 4 = 12

then you do the same to the 1cm and you get:

1 x 4 = 4

Therefore:

1cm : 3m
4cm : 12cm

the model is 4cm

the answer is the above in bold
hope it helped :)

Write a scenario that could work for the following line of best fit: y = 0.2x + 7.6. Explain the slope and intercept in this con
Ipatiy [6.2K]
In this question we know what the “y-intercept is,so if we go to our graph we can easily just plot the point 7.6 on the y axis of a number line. It also gives you the slope in decimal form so we would want to convert that from 0.2 to 1/5. And remember the slope is how many places you move to get to the next point on the number line. So from the point 7.6 we would move up 1 over 5 to the right because it is a positive number. Your line should run across the upper segment of the number line and your line should make a 20 to 30 degree angle shift

Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs $3.25Then, he wan
stepan [7]

Answer:

 is the correct answer.

Step-by-step explanation:

As per the question statement:  

Cost of Chocolate milk which is ordered already = $3.25.

Benjamin want his bill to be at most =  $30

Each stack of pancakes contains 4 pancakes.

Each stack of pancake costs= $5.50

Given that S represents the number of stacks of pancakes bought.

We have, Cost of 1 pancake = $5.50

Now, let us calculate the cost of the number of stacks of pancakes bought.

\text{Cost of one stack of pancakes}\times \text{Number of stacks of pancakes bought}

i.e.  

5.50S

So, total bill = Cost of chocolate milk shake + Money spent on stacks of pancakes = \$3.25+5.50S

Now, this money should be lesser than or equal to $30 because maximum bill that Benjamin wants is $30.

So, the inequality can be written as:

\bold{3.25+5.50S \le 30}
