Because you're trying to make them congruent, equal the two expressions to each other.
So, for #10 you would equal them so it would look like this.
2x+2=5x-19
Then you would just go ahead and simplify
2x+2=5x-19
-2x -2x
---------------
2= 3x -19
+19 +19
---------------
21=3x
--- ----
3 3
x=7
This means that x should be 7. You can check this just by plugging it in
2x+2
2(7)+2 = 16
5x-19
5(7)-19= 16
Same with #11.
x+8=3x-14
-x -x
--------------
8=2x-14
+14 +14
--------------
22=2x
--- ----
2 2
x=11
Check.
x+8
11+8= 19
3x-14
3(11) - 14 = 19
Answer:
Richhhh!!! Thanks for the points!!
Step-by-step explanation:
Answer:
2*18-18 > [ 28- 3*(2+4)]
Step-by-step explanation:
Evaluating the products, you have ...
36 - 18 ? 28 - 18
so you're comparing 36 to 28, or 18 to 10. Either way, the left side is greater:
2*18-18 > 28- 3*(2+4)
Answer:
The equation of cost of mulch is 
.
Step-by-step explanation:
The equations m (x) and g (m) are as follows:
It is provided that the cost of mulch requires is represented by the function g(m), where m is the area requiring mulch.
To compute the equation of cost of mulch based on the radius of the circle substitute the value of m (x) in g (m).
The equation of cost of mulch is:
Thus, the equation of cost of mulch is .
Answer: 65 minutes
Step-by-step explanation: 26 / 4 = 6.5
6.5 tables per 10 minutes so 6.5 x 10 = 65 min
