6x-21>3
Add 21 to both sides
6x>24
Divide 6 on both sides
X>4
14x+11>-17
Subtract 11 from both sides
14x>-28
Divide 14 on both sides
X<-2
Answer:37
Step-by-step explanation:
<h3>
Answer: x = 29</h3>
========================================================
Work Shown:
A = 2x+3
B = x
angles A and B are complementary, so they add to 90 degrees
A+B = 90
(2x+3)+(x) = 90
2x+3+x = 90
2x+x+3 = 90
3x+3 = 90
3x+3-3 = 90-3
3x = 87
3x/3 = 87/3
x = 29
Extra info:
2x+3 = 2(29)+3 = 58+3 = 61
Note that 29 and 61 add to 29+61 = 90
Answer:
29
Explanation:
Let John be x years old.
Michael is <span>x+17</span> years old.
In four years time, the sum of their ages will be 49:
<span>x+x+17+2<span>(4)</span>=49</span>
<span>2x=24</span>
<span>x=12</span>
So Michael is <span>12+17=29</span> years old now.
