Step-by-step explanation:
3x - y = 74
4y = x
Replace x in the first expression by 4y
3x - y = 74 ➡ 3(4y) - y = 74
12y - y = 74
11y = 74
y = 74/11 we can use this to find x
4y = x
4 × 74/11 = x
296/11 = x
Answer:
$600.25
Step-by-step explanation:
12.25 per week
46hrs last week
40+ = overtime
Overtime = t*1.5
------------------------------
46-40= 6hrs of overtime
40*12.25= 490 - this is her money for working 40hrs.
To figure out the money amount of overtime pay--- 12.25*1.5= 18.375 (18.38)
<em>18.38*6= 110.25</em>
add now
<em>110.25+490= $600.25</em>

Answer:
2 unit/time²
Step-by-step explanation:
Given the equation:
v(t) =t^2-3t
At interval ; 1, 4
V(1) = 1^2 - 3(1)
V(1) = 1 - 3
V(1) = - 2
At t = 4
V(4) = 4^2 - 3(4)
V(4) = 16 - 12
V(4) = 4
Average acceleration : (final - Initial Velocity) / change in time
Average acceleration = (4 - (-2)) ÷ (4 - 1)
Average acceleration = (4 + 2) / 3
Average acceleration = 6 /3
Average acceleration = 2
