Answer:
Distributive property
Step-by-step explanation:
The distributive property states a(b+c)=a*b+a*c. This property states that when you multiply more than one thing, you must be sure to multiply everything. When you order fast food combos, you do the distribution property to receive the correct order.
If I order 3 Happy Meals, then I will receive
3(hamburgers +fries + drinks +toys)
3 hamburgers+3 fries+3 drinks+3 toys.
If I don't, then I have broken the distribution property.
Answer:
im pretty sure #9 is just y=7x... it should be parallel with y=7x-3 since it has y intercept of 0 rather than -3.
Answer:
(42,28)
Step-by-step explanation:
set up the problem by converting percentages to decimal
x+y=70
.30x+.80y=50(x+y)
solve for x, so minus y in order to get it x alone. equation should look like this: x=70-y
30(70-y)+80y=50(70-y+y)
solve the equation for y
y=28
plug the value of y into the equation x=70-y
x=70-28
solve for x
x=42
check the solution of (42,28)
42+28=70
30*42+80*28=50(42+28)
simplify the equations
70=70
3500=3500
the ordered pair is a solution
so James needs 42 liters of 30% antifreeze and 28 liters of 80% antifreeze.

Its 3. Since 2 is a small number, lower than 5, so you round down to 3
