This is how I'd solve it:
bench = x x+3x=600
table = 3x 4x=600
x=150
The bench costs <u>$150</u> and the table costs <u>$450</u>; combined, they cost $600, so it's correct. I hope this helps you!
Slope= (y2-y1)/(x2-x1)= (-3-(-1))/(0-4)= -2/-4 =2/4 =1/2
Answer: slope =1/2.
Answer:
r = 6 3/23
Step-by-step explanation:
-128+138r=718
add 128 to each side
-128+128+138r=718+128
138r = 846
divide each side by 138
138r/138 = 846/138
r = 846/138
divide top and bottom by 2
r = 423/69
divide top and bottom by 3
r = 141/23
change this to a mixed number
r = 6 3/23
Answer:
It will be 120°
It because if you matched those two points you will have two angles of 90° degree inside that square and in the triangle at the above 120-90= 30 degrees for both angles and since that all angles of the triangle are equal 180 then 180-(30+30)=120°.
Sorry if my explanation isn't that good.
