Answer:
Step-by-step explanation:
1st equation:
3 cups = 3x
3x = 75
x = 25, cup = 25
2d equation
25 + lemon* lemons= 25 + y²
25 + y² = 89
y²= 89 - 25
y²= 64
y = 8, lemon = 8
3d equation
3 circles = 3c
3c = 44
c = 44/3 = 14 2/3
4th equation
25 + 32 + 14 2/3 = 71 2/3
the slope of the line is y = -1/2x -2
<3
382.5 because just multiply 8.50 times 45 hours
Answer:
<em>Tom must score 95 on his last test</em> to have an average of 92.
Step-by-step explanation:
Tom's average score (92) = the sum of all his five grades/the number of grades (5)
Given that A is the grade Tom must receive on his last test, we have the equation as follows:
92 = (89+94+86+96+A)/5
<=> A = 92 × 5 - (89+94+86+96)
=> A = 95
