Hello from MrBillDoesMath!
Answer:
-3x - 7
Discussion:
The order of operations states that multiplication and division are done before addition\subtraction. So
-2x +5/-5x - 7 =
-2x + (5/-5x) - 7 -
-2x -x -7 =
-3x - 7
Thank you,

Answer:
52 weeks are there in a year
Step-by-step explanation:
365/7
We need to do a system of equations here.
x + y = 275 (if you travel <em>x</em> km by bike and <em>y </em>km by bus, then you travel 275 km as given in the problem)
y = x + 55 (the problem stated that they were bussed (y) the amount they biked plus 55 more km (x + 55))
The second equation is already solved for y. So, we can plug it in to the first equation.
x + (x + 55) = 275
2x + 55 = 275 [combine x terms]
2x = 220 [subtract 55 from both sides]
x = 110 [divide by 2 to isolate x and solve for it]
Now we know that x is 110, the distance they traveled by bike.
And that's what we needed to answer the problem!
1/24 because you have a 1/6 chance of rolling a 2 and a 1/4 chance of pulling a spade and when multiplied you get 1/24
Y-(-8)=-0.24(x-3)
y+8=-0.24(x-3)
