Answer:
- infinitely many
- one solution
- no solution
- one solution
Step-by-step explanation:
1. 4x−x=2x+x
Simplifies to 3x = 3x, which is true for all values of x. Hence there are infinitely many solutions.
___
2. 2x+1=5
True only for x=2; one solution.
___
3. 4x+2=5x−x+4
Simplifies to ...
4x +2 = 4x +4
2 = 4 . . . . . . . not true for any value of x; no solution.
___
4. 2(x+4)=4(x+2)
Simplifies to ...
2x +8 = 4x +8
0= 2x . . . . . . . . . subtract 2x+8
True only for x=0; one solution.
Answer:
180 strips
Step-by-step explanation:
Note that:
1 yard = 36 inches
5 yards = x
Cross Multiply
x = 5 × 36 inches
x = 180 inches
Hence:
1 piece of fabric = 180 inches
How many 1-inch strips can be cut from the fabric?
180 inches = 1 piece of fabric
1 inch = x
x = 180 strips
Answer:
7/6
It's 7/6 because 6/6 make up a whole which is the 1 in 1 1/6
then there is that left over 1/6 to make it 7/6
Answer:
<h2><em><u>-x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em></h2>
Step-by-step explanation:
<em><u>If</u></em><em><u>,</u></em>
x = -2
<em><u>Then</u></em><em><u>,</u></em>
-x = -(-2)
=> <em><u>-x = 2 (Ans)</u></em>
