gi ve me brainliest and i give answer
Step-by-step explanation:
Xiao should have written this
Xiao's mistake was that
he forgot to put 3 times 30 so it
could be 90.
3(20) + 3(30)
60 + 90
150
Answer:
1/16ft²
Step-by-step explanation:
If 26 rolls fits into 1 5/8 ft² pan, then for us to get the number of square feet for each roll, we will fillw the steps;
26rolls = 1 5/8ft²
1 roll = xft²
26 rolls = 13/8 ft²
1roll = xft²
Cross multiply
26×x = 1×13/8
26x = 13/8
Ceoaa multiply
26x×8 = 13
208x = 13
x =13/208
x = 1/16 ft²
Hence the baker uses 1/16ft² for each roll
Would assume it to be 36x² - 25 = 0
<span>36x² - 25 = 0
</span>
<span>(6x)² - 5</span>²<span> = 0</span>
(6x + 5)(6x - 5) = 0 By difference of two squares.
6x + 5 = 0 or 6x - 5 = 0
6x = -5 6x = 5
x = -5/6 x = 5/6
x = +5/6 or - 5/6
