Answer:
rational
Step-by-step explanation:
Answer:
1.
2.
Step-by-step explanation:
One equation is already given in the statement which can give the result.
Lets assume the area of painting = d = 10 sq inch
Now following expressions will give the same answer.
1.
2. Multiplying the percentage d, As the area increases by 49 % which means that D is multiplied by increased amount of 49%
equation will be
3. Calculating the percentage increment = 1/1.49=0.67
Now dividing this value with d will give the same area.
Answer:
x=-3
y=3
Step-by-step explanation:
-27=-9x-18y equation 1
-5y-10x-15=0 equation 2
using equation 2 we have:
-10x -15 =5y
y= -2x -3 equation 3
using equation 3 in equation 1 we have:
-27=-9x-18(-2x -3)
-27= -9x +36x +54
-27-54 =27x
-81 = 27x
so we have:
x= -81/27
x=-3
y= -2(-3) -3
y= 6-3
y = 3
