Answer:
Step-by-step explanation:
Given that:
x + 4y = 30
x - 2y = 0
Subtracting both equations:
6y = 30
y = 30/6
y = 5
Putting in above equation
x + 4(5) = 30
x + 20 = 30
x = 10
i hope it will help you
30, 6+9= 15+4= 19+1= 20+10= 30
Answer:
n+7
Step-by-step explanation:
When we have any unknown quantity, we can call it mostly x,y,z
so, here
Let take an unknown number = n
then
we need to do here " sum of a number and 7 in algebraic form"
so, it becomes
n + 7 (Answer)
The range of F(x) = logb x is True
Measuring the figure with a ruler, length = 2 inch and width = 1.5 inch
It is given that 1/2 inch = 4 feet
1 inch = 4*2 = 8 feet
Area of rectangle = length * width
Length = 2*8 = 16 feet
Width = 1.5*8 = 12 feet
Area of Quintoe's bedroom = 16 feet * 12 feet = 
Hence option C is correct.
