When solving negative one over eight (x + 35) = −7, what is the correct sequence of operations?
Fantom [35]
The answer is <span>Multiply each side by −8, subtract 35 from each side

</span>- \frac{1}{8}(x+35)=-7
<span>
Multiply each side by -8:
</span>(-8)(- \frac{1}{8})(x+35)=(-8)(-7) \\  \\ &#10;1(x + 35) = 56 \\ &#10;x + 35 = 56
<span>
Subtract 35 from each side:
</span>x + 35 -35 = 56-35 \\  \\ &#10;x + 0 =21 \\  \\ &#10;x = 21<span>
</span>

NEED HELP ASAP!!
storchak [24]

Answer: 1.2 in

Step-by-step explanation:

The pythagorean theorem states that a²+b²=c².  Thus, 0.9²+b²=1.5².

1.5²=2.25

0.9^2=0.81

0.81 + b² = 2.25

1.44 = b²

b = 1.2

Hope it helps <3 :)
