8 0

Answer:

75

Step-by-step explanation:

Homework mean x 10%: (80+100+90)/3 x 0.1 = 90 x 0.1 = 9

Quiz mean x 25%: (84+90+72)/3 x 0.25 = 20.5

Test mean x 45%: (64+72)/2 x 0.45 = 30.6

Sum of means/percentage of grade: 9 + 20.5 + 30.6 = 60.1/.8 = 75.125

Anyone can help asap?
Varvara68 [4.7K]

Company A: 120 + 0.50x

Company B: 60 + 0.60x

Company A = Company B (solve for x)

(Here, x = miles)


120 + 0.50x = 60 + 0.60x

120 - 60 = 0.60x - 0.50x

60 = 0.10x

600 = x

Solve the following:<br>a) 2(5x – 3) = 24<br>b) 5(2x + 1) = 50​
likoan [24]

Answer:

x = 3 and x = \frac{9}{2}

Step-by-step explanation:

(a)

2(5x - 3) = 24 ( divide both sides by 2 )

5x - 3 = 12 ( add 3 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

(b)

5(2x + 1) = 50 ( divide both sides by 5 )

2x + 1 = 10 ( subtract 1 from both sides )

2x = 9 ( divide both sides by 2 )

x = \frac{9}{2}
