Answer:

n = 6.2/-10.4=0.5962

Step-by-step explanation:

What is the value of n in the equation. we would make n the subject formula -1.2(2n+4)+6=-9+4(2n+1)

Opening the brackets,

-1.2×2n -1.2×4 + 6= -9 +4×2n + 4×1

-2.4n -4.8 +6 = -9 +8n + 4

-2.4n -4.8 +6 = -9 + 4 + 8n= -5+8n

Collecting like terms

-2.4n-8n = -5+4.8-6

-10.4n =-6.2

n = -6.2/-10.4= 0.5962

Let's check, put n= 0.5962 in the equation

-2.4n -4.8 +6 = -9 +8n + 4

Lefthand side

-2.4×0.5962-4.8+6= -0.230

Right hand side

-9+ 8× 0.5962 +4

=-9 +4.7696 +4

=0.230

Right hand side = left hand side

9:7
Ratios are always simplified so by dividing both 18 and 14 by 2 you get 9 and seven. Because yellow triangles is stated first the 9 is put before the 7 blue triangles.

Chet needs to buy 4 work shirts, all costing the same amount. The total cost before Chet applies a $25 gift certificate can be n
Alborosie
Let us use x as the cost before Chet would apply a $25 gift certificate. Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate. This means that we do not need to add in the 25 yet since the question asks for the cost before the application of the discount. - Credits, <span>Taskmasters and Hegans</span>
