Step-by-step explanation: Since they collected 8 fewer today, to find yesterday u would have to add. 12+8=20. PS idk if that makes sense srry
The unit rate is $1.25 per pound
17.85714285714285 to nearest tenths is 17.9 .
It will take them 3/4 of an hour together.
Camille can mop and vacuum 1/2 of the house per hour.
Lawrence can mop and vacuum 1/2 of the house per hour.
Gaston can mop and vacuum 1/3 of the house per hour.
Working at this rate for x amount of time, they can all three complete 100% of the job:
1/2x+1/2x+1/3x=1
Combining like terms,
1 1/3x = 1
3/3x + 1/3x = 1
4/3x = 1
Divide both sides by 4/3:
4/3x÷4/3 = 1÷4/3
x = 1/1÷4/3
x = 1/1×3/4
x = 3/4
Hello:<span>
the equation is : y = ax+b
the slope is a : a×(2/3) = -1......(
perpendicular to a line : 2x-3y =7 with a slope of 2/3 because : y = (2/3)x-7/3)
a = -3/2 y=(-3/2)x+b
the line that passes through (-2, 1) : 1 =
(-3/2)(-2)+b
b = -2
<span> the equation is : y = (-3/2)x-2</span></span>
