What is the value of 7 + z ÷ 2, when z = 10?

Mathematics

To solve this problem, we must substitute the given value for z (10) into the expression and then simplify, as modeled below:

7 + z / 2

7 + 10/2

Now, in order for us to simplify this expression, we must remember the order of operations, outlined by PEMDAS. This tells us that we should compute values in parentheses first, then exponents, after that multiplication and division, and finally addition and subtraction. This means that we must perform the division in our problem and then the addition after. This is modeled below:

7 + 10/2

(Divide 10/2)

7 + 5

(Find the sum)

12

Therefore, your answer is 12.

Hope this helps!

Plug in 10 for z. Remember to follow PEMDAS (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction)

7 + 10/2

Divide 10 with 2

10/2 = 5

Add 5 with 7

5 + 7 = 12

12 is your answer

hope this helps

The following solutions to the given system of inequalities shown above would be option c : (-3, -5) option d : (0, 4)  option e. (4, 4)  and option f. <span>(2, -1) 
So how did I know the answer. To check this, you just have to substitute the values.
For example let us take option c (-3, -5)
y </span><span><  3x + 5
-5 </span><span><  3(-3) + 5
-5 </span><span><  -9 + 5
-5 </span><span><  -4 <<You see that -4 is greater than -5 which makes this inequality correct. This is the same process as with the other correct options.
Hope that this answer helps.</span>

julsineya [31]
<h3>Answer:</h3>

8/13

<h3>Step-by-step explanation:</h3>

Given in the question

Ratio of sandwiches white bread to brown bread is 10 : 3

white bread fraction = 10/13

brown bread fraction = 3/13

It is also provided that

2/3 white are vegetarian

1/2 brown are vegetarian

So

for white bread vegetables sandwich we will find 2/3 of 10

    20/3/13

for brown bread vegetable sandwich we will find 1/2 of 3

    3/2/13

adding both

 20/3/13 + 3/2/13

 8/13 (approximate)

A town in east Texas recieved 10 inches of rain in two weeks. If it kept raining at this rate for a 31-day month, how much rain
Gelneren [198K]
The best way to approach this problem is to find out how much fell in week. As you know what two weeks is, you simply have to halve this, giving you that one week is 5 inches of rain. One you have this, you can multiply this by 4 (as this will give you 4 weeks, or 28 days), and this gives you 20 inches in 28 days. You should then find the odd three days. If you divide 5 by 7, this will give you the rain fall in one day. 5/7= 0.8 inches per day. You then have top multiply this by 3 (as you've got three odd days), and this gives you 2.4. You then have to add together 2.4 and 20, giving you 22.4
Therefore, if the rain continued to fall at the same rate for 31 days, it would receive 22.4 inches of rain.
Hope this helps :)
