Plz i justt whant awnser will be marked brillent i will report if ur here for points!!

Question 7: Distributive

You multiple the outside element by each element inside the parenthesis

Question 5: 1.2x + 12.3y

2.4(3x + 2y) - 1.5(4x - 5y)  = 7.2x + 4.8y - 6x + 7.5y  = 1.2x + 12.3y

Question 3: 1 (3/5)x - (3/10)y

(2/5)(4x - 3y/4) = (8/5)x - 6y/20 = 1 (3/5)x - (3/10)y

Question 2: 1 (7/15)x

(4/5)x + (2/3)x = (12/15)x + (10/15)x = (22/15)x = 1 (7/15)x

Question 1: -2x + 3y

(3/4)(8x-4y) - (2/3)(12x - 9y) = 6x - 3y - 8x + 6y = -2x + 3y

Hope this helps!

Question 7: Distributive

Question 5:

Question 3:

Question 2:

Question 1:

Step-by-step solution:

Question 7

Distributive property, . It says that multiplying the sum of two or more addends (numbers or terms added together) by a number (a) will give the same result as multiplying each addend individually. It is the same as the distributive property of multiplication over subtraction, except it will give the difference.

Question 5

Use the distributive property:

Question 3

Use the distributive property again:

Now you have to convert to mixed form:

It will give 1 with remainder 3, therefore

Question 2

Mixed form again:

Question 1

greater than one

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
