Answer:
1/4 mile
Step-by-step explanation:
A = length · width
let 'n' = length
1/8 = 1/2n
8n = 2
n = 2/8 or 1/4
7 * 4 = 28
28 + 5 = 33
33 / 3 = 11
11 - 7 = 4
The number she thought of is 4
Answer:
x = 8/3 and y = 32/3
Step-by-step explanation:
Add the two equations, getting -3y = -32, thus y = 32/3
Sub for y in first equation, getting 5x + 32/3 = 24
5x = 40/3
x = 8/3
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
Given:
T (-3,4) ; O (-4,1) ; Y (-2,3)
T'(-1,1) ;
T
-3 move forward 2 points to reach -1
4 move forward 3 points to reach 1
O
-4 move forward 2 points to reach -2
1 move forward 3 points to reach -2
Y
-2 move forward 2 points to reach 0
3 move forward 3 points to reach 0.
O'(-2,-2) ; Y'(0,0) 1st option.
