Answer:
32 + 4(h) = 60
Step-by-step explanation:
The 32 in the equation represents the $32 Ali already has. The 4 represents how much she makes per hour. And the h represents how many hours Ali needs to reach her goal of 60. Now all you need to do is find h. h should equal 7. 32 + 4(7) = 60.
The expressions equivalent to -0.5(1.7+1.7) are -0.5(1.7) - 0.5(1.7)
and 2(-0.5(1.7))
<h3>Distributive law of expansion</h3>
Given the expression below;
-0.5 (1.7 + 1.7)
According to the distributive law;
A(B+C) = AB + AC
Expand
-0.5(1.7) + (-0.5)(1.7)
-0.5(1.7) - 0.5(1.7)
2(-0.5(1.7))
Hence the expressions equivalent to -0.5(1.7+1.7) are -0.5(1.7) - 0.5(1.7)
and 2(-0.5(1.7))

ANSWER
<span>A. x + 30 = 10 and x + 30 = –10
EXPLANATION
</span><span>If x represents the depth of Laurie at a given moment, then the distance between his current depth and -30 feet is given by
| x - (-30) |
which can be simplifed into
| x + 30 |
We use absolute value because distance cannot be negative.
Laurie must stay within 10 feet. Therefore, the distance x is from -30 feet has to be equal to 10 to find the maximum and minimum depths that Laurie can stay between:
| x + 30 | = 10
When we solve this absolute value equation, we work with two cases.
Case 1: When x + 30 is positive, then |x+30| = x+30 (no change) and we have the equation
x + 30 = 10
</span>Case 2: When x + 30 is negative, then |x+30| = -(x+30) so as to force the distance into a positive number. Then this gives us the equation
<span> -(x+30) = 10
which we can multiply both sides by -1 to get
x + 30 = -10</span>
