Answer:
t =12 m
Step-by-step explanation:
We can use similar triangles and proportions to solve this problem.
Put the smaller triangle on top and the larger triangle on bottom
12 9
------ = -------
16 t
Solve by using cross products
12 t = 9*16
12 t =144
Divide by 12
12t/12 = 144/12
t = 12
Answer:
If the question is asking for a solution for both, then only point (0,2)
Point (0,2) is a solution to both equations
Point (5,3) is a solution to neither (meaning not any of the equations)
Point (-2, 16) is not a solution to the<u> first equation</u>, but is to the <u>second</u>
Point (-4, -9)<u> is a solution</u> to the first, but <u>not </u>to the second.
Step-by-step explanation:
Using the Property of substitution. 7x-4y=8
(0,-2)
7(0)-4(-2)=8
7(0)=0
-4(-2)=8
0+8=8
This solution is true.
(5,3)
7(5)-4(3)=8
7(5)=35
-4(3)=-12
35-12=23 (not 8)
This solution is not true.
(-2,16)
7(-2)-4(16)=8
-14-64=-78 (not 8)
This solution is not true.
(-4,-9)
7(-4)-4(-9)=8
-28+36=8
This solution is true
__________________________________________________________
Y=-9x-2
(0,-2)
-2=-9(0)-2
-9(0)=0-2=-2
-2=-2
This solution is true
(5,3)
3=-9(5)-2
-45-2=-47
3=-47
This solution is not true
(-2,16)
16=-9(-2)-2
16=18-2
16=16
This solution is true.
(-4,-9)
-9=-9(-4)-2
-9=36-2
-9=34
This solution is not true.
Answer - 720
You would do 6 x 5 = 30 to get how many dawn had
Then you’d do 30 x 4 = 120 to get how many Charlie had
Then you’d do 120 x 3 = 360 to get how many Ben had
Then 360 x 2 = 720 to get the original amount
Have a good day :)
