Answer:
BC = 9
Step-by-step explanation:
Given AC = 26
BC=7x + 2
AB = 9x + 8
Since BC and AB are two parts of AC. Therefore we can write in the following form.
AC = AB +BC
Now insert the given values in the above formula.
26 = 9x + 8 + 7x + 2
26 = 16x + 10
26 – 10 = 16x
16 = 16x
x = 16 / 16
x = 1
Now insert x = 1 in BC=7x + 2
BC = 7 (1) + 2
BC = 9
The rectangle has a perimeter P of 58 inches.The length l is one more than 3 times the width w.write and solve a system of linear equations to find the length and width of the rectangle?
Answer:
Length(L)=22 inches
Width(W) = 7 inches
Step-by-step explanation:
GIven:-
Perimeter (p)=58 inches,
Length(L)= one more than 3 times the width(W)
Let, W=x ---------------------------------(equation 1
-----------------------(equation 2)
Here x is unknown and to find the Width(W) we have to find the value of x.
Now,
Perimeter of rectangle(p) = 2 times length(L) + 2 times width(W)
----------------(from equation 1)
----------------(given p=58 inches)
----------------------(equation 3)
Now substituting the value of equation 3 in equation 2.
as, 
-----------------------(from equation 1)
inches -------------------(equation 3)
Therefore, Length(L) = 22 inches and Width(W) = 7 inches.
- Obtuse = one side is more than 90 degrees
- Acute = all sides are less than 90 degrees
- Isosceles = two sides are of the same length
- Equilateral triangle: all angles are of same measure (60)
- Scalene: all sides are of different lengths
- Right Triangle: One of the angles equals 90 degrees.
14 and 22 are the two numbers in question
An expression to represent this problem would be 2/y-3 as it asks for an expression that shows the answer to three less (meaning 3 will be subtracted from) than the quotient of the expression 2/y.
