<span>The answer is that x = 21/9.
Start with the original: 4(2x - 1) - 7 = 4 - x + 6
Now distribute the 4:</span> <span> 8x - 4 - 7 = 4 - x + 6.
Now combine the like terms. 8x - 11 = -x + 10.
Now add x to both sides. 9x - 11 = 10.
Now add 11 to both sides. 9x = 21.
And divide by 9 on both side. x = 21/9. </span>
Answer:4/5
Step-by-step explanation:
2/15 + 10/15=12/15=4/5
easy right?
34.2. You multiply 11.40 by .3 to find how many pounds they use which is 34.2 or it is 38 if you divide.
Answer:
∠1 = 52
∠2 = 128
∠4 = 128
Step-by-step explanation:
∠3 and ∠1 are vertical angles
As we now vertical angles are congruent
So if ∠3 = 52°, then ∠1 also equals 52°
∠3 and ∠4 are supplementary angles
supplementary angles add up to equal 180
Thus, ∠3 + ∠4 = 180
If ∠3 = 52°
Then 52 + ∠4 = 180
180 - 52 = 128
Hence, ∠4 = 128
∠4 and ∠2 are vertical angles
Like stated previously vertical angles are congruent
So if ∠4 = 128 then ∠2 also equals 128
