See attached picture for the answer:
3.5=.12x
3.5*.12 you multiply .12 and 3.5 because each ounce is equal to 12 cents
.42 is how much she spent on rice
Associative allows the combining of like terms (Both with variable z)
Distributive allows the 5 to distribute through
5(11z+6z+29)
5(17z+29)
5(17z)+5(29)
<span>85z+145</span>
V30% mixture + v100% mixture = v60% mixture
0.3(10-x) + x = 0.6(10)
3 - 0.3x + x = 6
0.7x = 6 - 3
0.7x = 3
x = 3/0.7
x = 4.286 quarts
If the slope of the number is positive (the graph goes upward from left to right), then m will be positive, but if the slope is negative (the graph goes downward from left to right), then m is negative. So, no. M does not have to be a positive number, it may also be negative.
