Answer:
Step-by-step explanation:
just simplify the LHS first.
You can either multiply 1/5 by (x+3) and then solve
or
multiply both sides by 5 to get rid of 1/5 on LHS
I will multiply by 5
(x+3)= -10x-15 ( 5*1/5(x+3)= -5(2x+3)
now rearrange the equation
x+3=-10x-15
-10x-15-x-3=0
-11x-17=0
-11x=17
x= -17/11
Answer:
Not solutions.
Step-by-step explanation:
-5x+6y=-5
6y=-5+5x
6y=5x-5
y=5/6x-5/6
-5/6 is about -0.833
And the slope is 5/6.
So for every x there is 5/6y.
This means (1, 4) won't work cause it's too low.
Also 5/6*6=5. this is too low too.
So they aren't solutions.
Answer:
length: 12 ft
area: 72 square feet
Step-by-step explanation:
Let L represent the length of the mat in feet. Then L/2 is the width and the perimeter is ...
P = 36 = 2(L +L/2) = 3L . . . . . substitute the given information and simplify
12 = L . . . . . . divide by 3
The length of the mat is 12 ft.
__
The width of the mat is L/2 = 6 ft, and the area is the product of length and width.
Area = (12 ft)(6 ft) = 72 ft^2
The area of the mat is 72 square feet.
Answer:12
Step-by-step explanation:
12x9=108
108-7=101
Your welcome
You could put,
19
+ 6
———
25
Then write,
19+6=25
