2x99=99+99
3a+3a=2x3a=6a
3x11+3x19=3x30
Answer:
Let x be the number of pencils Steve bought.
Let y be the number of erasers Steve bought.
x=y+5
0.1x + 0.25y = 1.55
Solving the system, our answer is: (8, 3)
So, she bought 3 erasers.
Let me know if this helps!
Cool problem !
Two pages of a book that face each other are consecutive integers, and one of them is even and the other one is odd.
So let's look at half of 69.
That's 34.5.
So let's try page 34 and page 35.
That works !
Equation of shaded triangle is
.
Solution:
Length of the rectangle = 14 ft
Breadth of the rectangle = 8 ft
Area of the rectangle = length × breadth
= 14 × 8
In this rectangle the diagonal splits the rectangle into two equal halves.
Area of the shaded triangle = Half of area of rectangle

Area of the shaded triangle = 
Hence the equation can be used to calculate the area of the shaded
triangle is
.
-48 = 2x - 8y
-24 = x - 4y
4y = x + 24
y = (1/4)x + 6
Slope of the line
1/4
