Answer:
Find other solutions in explanation
x = 250
y = 1750
Step-by-step explanation:
x = cost per copybook
y = cost per pen
2. Sum of the cost of 4 copy books and 3 pen is equal to 7750
3.)
2x+y=2750 - - (1)
4x + 3y = 7750 - - - (2)
From (1)
y = 2750 - 2x
Substitute y = 2750 - 2x into (2)
4x + 3(2750 - 2x) = 7750
4x + 8250 - 6x = 7750
-2x = - 500
x = 500/2
x = 250
y = 2750 - 2(500)
y = 2750 - 1000
y = 1750
When
the perimeters of both figures will be equal.
Step-by-step explanation:
Step 1:
The triangle has side lengths of
and
.
The perimeter of the triangle is the sum of the lengths of the sides.
The perimeter of the triangle 
Step 2:
The perimeter of the hexagon is 6 times its side length. The side length 
The perimeter of the hexagon
Step 3:
To determine the value at which both the perimeters are equal, we equate both the equations to each other.

So when
the perimeters of both figures will be equal.

Answer:
the answer is 1,674
Step-by-step explanation:
because if 3hours in 558 miles you multiply the 3hours in 558miles and the answer is 1,674
Answer:
b=-79
Step-by-step explanation:
(10,11) means x=10,y=11
m=9 b=?
y=mx+b
Make b the subject of formula
b=y-mx
b=11-9(10)
b=11-90
b=-79
