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!
X² + x - 20
= (x+5)(x-4)
x + 5 = 0
x = -5
x - 4 = 0
x = 4
hence the answer is C
someone hurry i also need help on this question!
I got 60 as my answer
you ALWAYS do your parentheses first
then you do 8+5 and that equals 13•6-9
13 times 6 is 78. then you subtract 9 which will leave you with 60. hope that helped ☺️
A = 3 1/2 closest to friday
B = 3 closest to saturday
C = 6 1/2 just add 3 + 3 1/2 = 6 1/2
