Answer: x = 17
Step-by-step explanation: combine all of those numbers.
3x+x+22.
Combine like terms, so
4x + 22 = 90 (90 is the sum of 2 complementary angles)
Subtract 22 from both sides to get
4x = 68
Now divide by 4 to get x which is
x = 17
<span>Paul is not correct. A good understanding of place value is important to solve this problem. From the left, you look at the ones, tens, hundreds, and thousands for place value. In the number 6367, one 6 is in the tens column and the other 6 is in the thousands column. This means that one six is 100 times as great as the other 6. If it was 10 times as great, it would be in the hundreds column.</span>
Answer:
x=151/64 y=9/8 z=-51/32
Step-by-step explanation:
2x+2y+5z- (2x-y+z)=-1-2
3y+4z=-3
2x+2y+5z- (2x+4y-3z)=-1-14
-2y+8z=-15
We have two equations 3y+4z=-3 and -2y+8z=-15 (We get it due to elimination method)
3y+4z=-3 (2)
-2y+8z=-15 (-3)
6y+8z=-6
6y-24z=45
(6y+8z)- (6y-24z)= -6-45
32z=-51
z=-51/32
3y-204/32=-3
3y= -96/32+204/32
3y=108/32
y=36/32=9/8
2x+2*9/8+5*(-51/32)=-1
2x+9/4-255/32=-1
2x+72/32-255/32=-1
2x-183/32=-32/32
2x=151/32
x=151/64
