Answer:
a.4
Step-by-step explanation:
Because 10 is greater than 6 so, it turns into a positive instead of a negative. and of course 10 + 6 = 4
cost = 2*3.07+10.36
cost = 6.14+10.36
cost =16.50
20-16.50=change
3.50
She will get $3.50 change
to find this answer we use proportional reasoning.
3 cups of flour:2 teaspoons of vanilla
3:2
if 5 cups of flour are used then we adjust the ratio to keep it proportional
the vanilla is 'x' because we don't know the value (yet)
5:x
then we set it up in an equation and solve
3/2=5/x
2 multiplied by 5 divided by 3 x=3.33
5:3.33
you need 3.33 teaspoons of vanilla for 5 cups of flour
a) a+b=b+a
the commutative property of whatever number is it turned around
b) a * b= b*a
the commutative property of whatever number is it turned around
c) b+0=b
the additive property is whatever adds to zero is that number.
d) b*1=b
the multiplication property of one is whatever mutilply by 1 is that number.
Answer: yes they should do all of those
