Answer:
B because not only are we talking about two states, but out of the amount given they was more likely seen.
Answer:
2x+y=20 and -5y=6x+12 are your equations.
You can turn 2x+y=20 into y=-2x+20
Substitute this value of y into the other equation.
-5(-2x+20)=-6x+12
10x-100=-6x+12
16x=112
x=7
Substitute this value of x into the other equation.
2(7)+y=20
y=6
Your answer is x=7 and y=6.
20.70=3p+3
17.70=3p
$5.90=p
So if you only needed the equation to describe the word problem it is
$20.70=3p+3
If you want to know how much each pizza was it is $5.90; salad $3.00
I tend to flip so x is on the left, so:
-2x - 1 = 16
-2x = 17
x = -17/2, which is -8.5
Rounding up, your answer would be x = -8 !
Answer:
Step-by-step explanation:
so there are 13 multiples of three and there's 40 numbers in total. 40 times 2.5 is 100. you do 13 times 2.5 which equals 32.5 percent chance of getting a multiple of three. so you do 100 minus 32.5= 67.5 percent chance of not getting a multiple of three.
Hope this helps:)
