Answer:
Step-by-step explanation:
y=x+7.........(1)
y=3x+5.......(2)
Equating the two equations
3x +5 = x + 7
3x -x = 7 - 5
2x = 2
x = 2/2
x = 1
Putting x = 1 in (1)
y = x + 7
y = 1 + 7
y = 8
Answer:
units.
Therefore, Option C is correct.
Step-by-step explanation:
We have given a pentagon ABCDE
We need to calculate its length
That means we have to find the distance of AD
So, coordinates of A(1,6) and D(4,-2)
Using distance formula:

Here,
On substituting the values we will get:

On simplification:


.
Hence, the length of AD is
units.
Therefore, Option C is correct.
Answer:
-3x +4=x-2,.........

If it's wrong....I apologize in advance!
Answer:
it would take 63 weeks to save that much money
Step-by-step explanation:
divide 25 by 9 and get 2.7 then multiply 2.7 by 63 to get 175
Width = w
Length = w + 1
Area = 30
w(w+1) = 30
w² + w = 30
w² + w - 30 = 0
w² + 6w - 5w - 30 = 0
w(w + 6) -5(w + 6) = 0
(w + 6)(w - 5) = 0
w = 5 or -6
Since the width cannot be negative, the width is 5 units.
Hence, the width is 5 units and the length is 6 units.
