So hmmm check the picture below
now
now, that's how many yard³ are there for that slab, now, how much is the cost?
well, each yd³ costs $40, thus
Answer:
x=(-10)
Step-by-step explanation:
ok, so the first step is to organize the equation: on the left we will put the X numbers, and on the right normal numbers, like this:
-X+2X=-6-4
(p.s I hope that you know that when you transfer numbers and other values,the sign changes : from plus to minus and vise versa)
so now, if you will do the simple math,you will find the value of X.
X=(-10)
Y = (1/5)x -2
for a perpendicular line, you make the slope the reciprocal of the other equation
1st decimal place=tenth
2nd=hundreth
to round, you look at the place after it
so 13.8924439894 to tenth
look untill hundreth
13.89
if hundreth<u>></u>5, round tenth up
if hundreth place<5 leave tenth as is
13.89
9<u>></u>5
round up
8+1=9
13.9 is to theh tenth
