you have to simplify it
then isolate the variable
then you will get x=6
Answer:
b and e
Step-by-step explanation:
these are the only expressions that if you simplify all the way out you get 12y+24.
Answer:
Option D. 5x + 12y + 4z is the corrct one.

Answer:</h2>
<em>Question 1)</em>
5x
<em>Question 2) </em>
0.22a
<em>Question 3)</em>
8 + 6n
<em>Question 4)</em>
25
<em>Question 5) </em>
ab+c=14
<h2>
Step-by-step explanation:</h2>
<u>Ques 1)</u>
The product of 5 and x.
Product of two numbers means that it is obtained by multiplying them.
Hence, the expression so obtained is: 5x
<u>Ques 2)</u>
22% of a
It means that:
22%×a
Also, we know that:
22% =0.22
This means that:
22% of a=0.22×a
i.e.
22% of a=0.22a
<u>Ques 3)</u>
8 more than the product of 6 and n.
The product of 6 and n is given by: 6n
and 8 more than there product will be given by:
8+6n
<u>Ques 4)</u>
Evaluate: 30 − m/6 for m = 30
i.e. we put m=30 in the expression and get the resulting value.
i.e. we have:
30-m/6=30-(30/6)
i.e.
30-m/6=30-5
i.e.
30-m/6=25
<u>Ques 5)</u>
Evaluate ab + c for a= 2, b = 5, c = 4.
i.e. we will put the value of a,b and c in the given expression and find the value.
i.e.
2×5+4= 10+4
i.e.
ab+c=14
Answer:
8 and 10
Step-by-step explanation:
All you need to know to begin setting this up is that to get from one even integer to the next consecutive even integer, add 2.
Start with x = an even integer (yes, because you say so!)
Next even integer = x + 2
"five times the first integer is equal to four times the second integer"
5x = 4(x + 2)
Distribute the 4.
5x = 4x + 8
Subtract 4x
x = 8
The two integers are 8 and 10
5(8) = 4(10) as desired!
