Answer:106

Step-by-step explanation:

Let number of white marbles be w

Let number of red marbles be r

w+r = 126---------1

w = 6 +5r-----------2

Put eqn 2 in eqn 1

6+ 5r + r = 126

6 + 6r = 126

6r = 120

r = 20

w = 6 +5r =6+100

= 106

Tanya [424]

Answer:

33i - 12

Step-by-step explanation:

8i - (12 - 4i) + 7 \sqrt{ - 9}   \\  = 8i - 12  + 4i + 7 \sqrt{9  \times ( - 1)}  \\ = 12i - 12 + 7 \times 3 \sqrt{ - 1}  \\ = 12i - 12 + 21i  \:  \: ( \because  \sqrt{ - 1} = i)\\  = 12i + 21i - 12 \\   \therefore \red{ \bold{8i - (12 - 4i) + 7 \sqrt{ - 9} }=  \purple{ \bold{33i - 12}}}

There are 9 classes of 25 students each 4 teachers in two times as many chaperones as teachers each bus hold a total of 45 peopl
Tanya [424]

Answer:

Least number of bus require for trip = 5 buses (Approx)

Step-by-step explanation:

Given:

Total number of classes = 9

Number of student in each class = 25

Number of teacher = 4

Number of chaperones = Double of teacher

Bus hold = 45 people

Find:

Least number of bus require for trip

Computation:

Total number of student = 9 × 25

Total number of student = 225

Number of chaperones = 4 × 2

Number of chaperones = 8

Total people = 225 + 8 + 4

Total people = 237

Least number of bus require for trip = Total people / Bus hold

Least number of bus require for trip = 237 / 45

Least number of bus require for trip = 5.266

Least number of bus require for trip = 5 buses (Approx)

Someone help plz plz plz
prisoha [69]

Answer:I think it's 3 7.75/20 hours

Step-by-step explanation:

Multiply 2/15 by 20 (2x20 and 15x20)

Then 13/20 by 15 (13x15 and 20x15)

Subtract (195/300 - 40/300)

And you get 155/300

Then divide by 20 because dividing by 15 gives you 10.333333

So divide 155/300 by 20 (155÷20 and 300÷20)

And you get 7.75/20

Finally subtract the 2 hours from 5 hours and get 3 hours

Your answer is 3 7.75 hours
