(5.6)(1.8) the answer is 10.08
Answer:
y= -2x........eqn i
y=5x+3......eqn ii
substituting the value of Y from eqn i in eqn ii, we get,
-2x=5x+3
-7x=3
x= -3/7
so, y= -2x= -2× (-3/7)
so, y= 6/7
Answer:
2 fifths 2/5
Step-by-step explanation:
10 sided dice has 10 possibilities so 7 8 9 10 are even or greater than 7 that's 4 out of 10 numbers but in simplest form would be 2/5 (2 fifths)
Let the increase be x m
new length=(7+x)m
new width=(4+x) m
the current area of the garden is:
Area=length*width
A=4*7=28 sq. meters
when the area is doubled we shall have:
28*2=56
thus the new area will be:
(x+7)(x+4)=56
x^2+11x+28=56
x^2+11x-28=0
solving for x we get:
x=2.1
thus the dimensions are:
length=7+2.1=9.1
width=4+2.1=6.1
