<span>Let x = the width
:
It says,"The length of a rectangle is 4 less than 3 times the width." write that as:
L = 3x - 4
:
If the perimeter is 40, find the dimensions of the rectangle.
:
We know: 2L + 2W = 40
:
Substitute (3x-4) for L and x for W
2(3x-4) + 2x = 40
:
6x - 8 + 2x = 40; Multiplied what's inside the brackets
:
6x + 2x = 40 + 8; do some basic algebra to find x; (added 8 to both sides)
:
8x = 48
:
x = 48/8
:
x = 6 which is the width
:
It said that L = 3x - 4, therefore:
L = 3(6) - 4
L = 18 - 4
L = 14; is the length
:
Check our solutions in the perimeter:
2(14) + 2(6) =
28 + 12 = 40</span>
I will go with 9/10 because 9/10 =1.111111 and 4/5=1.25 so yes 9/10
Graph the linear system and tell how many solutions it has. If there is exactly one solution, give the solution 4X-5Y=2 8X+Y=4 Step 1. Graphing the above linear system of equations yields the following Step 2. Based on the above graph the intersection point is (0.5, 0) or x=0.5 and y=0.
If this helped, if u mind mark me as brainliest
Equation: 4x + 2 = x - 7
Solve equation
Subtract x from both side
3x + 2 = -7
Subtract 2 from both side
3x = -9, x = -3
Solution: the number is -3
Answer:
a=4m
b=63x¹2 - 35x6 maybe you formatted/typed this wrong, but this is impossible..?
c=4
