<u>Answer</u>
9 Banners.
<u>Explanation</u>
If to make 1 banner we need 4/3 sections, then to get the number of banner that can be made from 12 sections, we proceed as follows.
12 ÷ 4/3 = 12 × 3/4
= (12 × 3) ÷ 4
= 36/4
= 9 Banners.
Answer:3 lines could be used
Step-by-step explanation:
You need 2 points to draw a line. The order doesn't really matter. Line AB is the same as line BA. The problem is to select 2 points out of 3 to draw different lines. If we do the same to the others, we get the following pairs of points to draw lines.
AB , AC
BA , BC
CA , CB
which is only 3 lines
To solve a problem like this, you will need to use substitution or elimination. For the sake of an example I will solve this using substitution.
First, solve one of the equations for x or y:
3x-5y=-39
3x=-39+5y
X=(-39+5y)/3
Then substitute for the value of x in the second equation:
6x+2y=-42
6((-39+5y)/3)+2y=-42
Solve for y:
-78+10y +2y=-42
-78+12y=-42
12y=36
Y=3
Once you've solved for y, you can plug in it's value to find x:
X=-39+5(3)/3
X=-24/3
X=-8
So, we can conclude that the correct answer is B. (-8,3)
Hii, i don’t do kpop or whatever but thanks for the points !! have a great day
Answer:
Part A Answer = A=28
Part B Answer is B = 9/16 + C =0.56
Step-by-step explanation:
1 = A. 28 This is because the percentage rate works out at 43.75%
2. 9/16 also, 0.56 This is because 9/16 has decimal 0.56 we can work this out by looking at the inverse of 1 ; 1= 16 16/9 = 1.77/3.17 which adds to 4.94 = 10 x 0.49 4 representing 4 from 20 =16 and 9 representing the proportion.
