Math
One pie costs 0.10
you are buying 40 pies so...
40 x 0.10 = $4
one cup of coffee costs 0.50
you are buying 20 coffee so...
20 x 0.50 = $10
$4 + $10 = $14
It costs $14 to buy 40 pieces of pie and 20 cups of coffee
Answer:
A
Step-by-step explanation:
because the difference between each new number y(-2, -4, -6, -8) x(3, 6, 9, 12) is the same. For the y column it decreases by 2 each time and for the x column it increases by 3 each time. Therefore, yes, -2/3 is the correct answer
Answer:
You distribute whats outside the parentheses to whats inside. (Second line) Then, you add like terms, which is on one side, -15+2 is -13(third line). Then you single out the variable keeping it on one side by ,simply, subtracting 3x from 15x which is 12x(fourth line). Then you subtract 10 from -13 which is doing the opposite to get the variable by itself, that equals to -23. And, if you can have a decimal, then it comes to -23/12
Step-by-step explanation:
5(3x+2) = 3(x-5)+2
15x+10 = 3x-15+2
15x+10 = 3x-13
12x+10= -13
12x = -23
-23/12
