Answer:

3/20

Step-by-step explanation:

If 2/5 are girls then to find boys, calculate

1(the whole class) - 2/5 which is 3/5.

Then if 3/4 of the boys are called Paul, that means the remaining 1/4 aren't.

1/4 × 3/5 = 3/20

1. Avital counted 40 green cars and 20 silver cars in the parking lot. If the number of green cars stay the same, how many more
Luba_88 [7]
X represents the number that would be added to the silver cars.


x/40= 4
X=40x4
x=160

Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4

Answer:

12. -11

13. 2

Step-by-step explanation:

12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction

For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.

From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.

Your new equation is -10-8+7 = -11

13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))

  • keep in mind there’s an addition between the two

Division and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17

Second multiply 5 x -3 = -15

Now you can combine the two answers using addition: 17 + (-15) = 2

The arena satisfaction survey was sent out to 650 people. In total 3/5 of people returned the survey. How many people returned t
Angelina_Jolie [31]

This is a proportion problem that involves cross multiplication

3/5 = x/650

650 x 3 = 1950

1950/ 5 =390

Or you could have done 650 x .6 (which is the decimal form of 3/5) and got 390 as your answer
