Hi Kristian
a - 3b = 22
a = b - 2
We need to solve a = b -2 for a
First, we need to substitute b - 2 for a in a - 3b = 22
a - 3b = 22
b - 2 - 3b = 22
-2b - 2 = 22
-2b = 22 + 2
-2b = 24
b = 24/-2
b = -12
Now substitute -12 for b in a = b - 2
a = b -2
a= -12 - 2
a= -14
Thus, the solution is a = -14 and b = -12
The correct option is the last one (-14,-12)
If you have questions about my answer, please let me know.
Good luck!
In this question we already know the value of 'b' so put the value b=2 in the equation
=|4(2)-8| + |-1-(2)^2| + 2(2)^3
=|8-8| + |-1-4| + 2(8)
=0 -5 +16
=11
<em>Answer:</em>
<em>The value of the number should be 1 (or less I think)</em>
<em>Step-by-step explanation:</em>
<em>At most means the highest value of the sum should be 27.</em>
<em>10x + 17 = 27</em>
<em>10x = 27 - 17</em>
<em>10x = 10</em>
<em>x = 10/10</em>
<em>x = 1</em>
<em>∴</em><em>The value of the number should be 1</em>
Answer:
40
Step-by-step explanation:
x = (180-100)/2 = 40
