<span>1 x + 1 y = 7 .............1
Total value
15 x + 28 y = 131 .............2
Eliminate y
multiply (1)by -28
Multiply (2) by 1
-28 x -28 y = -196
15 x + 28 y = 131
Add the two equations
-13 x = -65
/ -13
x = 5
plug value of x in (1)
1 x + 1 y = 7
5 + y = 7
y = 7 -5
y = 2
y = 2
x= 5 plain shirts
y= 2 fancy shirts </span>
Answer: 2 < x < 16
The triangle inequality theorem says that if we have a triangle with sides a,b,c then
b-a < c < b+a
with b being longer than 'a'
In this case, a = 7 and b = 9 and c = x
so we have
b-a < c < b+a
9-7 < c < 9+7 .... replace a with 7, replace b with 9
2 < c < 16
2 < x < 16 .... replace c with x
So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
Answer:
1. 3375 ft cubed
2. 200 cm cubed
Step-by-step explanation:
btw in the image the shapes are not drawn to scale
:D brainliest?
Use the formula for finding the area of a cylinder - V = (pi)r^2h
Add in the numbers you were given:
V = (22/7) 5^2 (175)
The volume is A) 13,750 ft3
draw a line through the greater than sign then you start by added for to both sides so -4 + 4 is equal to 0 8 + 4 is equal to 12 so now -i -2 goes into 8 -6 * so that means X is greater than -6
