The name for facts in subtraction problems: Fact Family is a group of math facts that uses the same numbers, for addition, and subtraction.
Answer: =====> I believe is, Subtraction Fact Strategies, or Fact Families.
1. ). Strategy: ===> Think Addition:
1.). Subtraction Description ====> Using the known addition fact to solve the subtraction problem. Ex. 13-5, think what goes with 5 to make 13?
2.). Strategy: ===> Fact Families
2.). Subtraction Description ====> Think of the fact family to recall the missing number.
3.). Strategy ===> Build Up Through
3.). Subtraction Description ===> Ten
Used when either the subtrahend or minuend is 8 or 9. Ex: 14-9: start with 9 and work up through 10: 9 and 1 is 10 and 4 more makes 5.
4.). Strategy ==> Back Down Through Ten
4.). Subtraction Description: ==> Working backward with 10 as a “bridge”. Ex. 15-6, Take 5 away from 15 to get to ten. Then take one more away, leaving 9.
Hope that helps!!! : )
Let x = one leg. the base is then 3x-17. the perimeter I'd given by x+x+3x-17=33
5x-17=33
5x=50
x=10
2 legs are 10 each and base is 13
It depends on the type of triangle like say it was a right triangle then a+b=c ok so you a=11 your b=18 then all you have to do is find you what c=s so c=x i hope this helped
Answer:
1 1/4 cups.
Step-by-step explanation:
This is a subtraction problem since Rob put too much sugar, and he only needed 4 1/8 cups. So:
5 3/8 - 4 1/8 = 1 2/8
Since they have the same denominators all you had to do was subtract the numerators and whole numbers; 5 - 4 = 1, and 3/8 - 1/8 = 2/8.
Now you have 1 2/8, which can be simplified.
1 2/8 = 1 1/4
I hope this helps you
