Step-by-step explanation:
B on edge
Answer:
Option A , C and D are correct.
Step-by-step explanation:
Double Facts states that the additions in which a number is added to itself.
then; by definition of double facts
Use Double facts to find the sum of 3 + 2
3 + 2
=3 + (3 - 1)
= 3+ 3 - 1
= 6 - 1
= 5
similarly,
3+2 = (1+2) + 2 = 1 + 2+2 = 1 + 4 = 5
Also;
3 + 2 = 3 + (1+1) = 3 +1+1 = 5
therefore, the double facts that used to find the sum of 3+2 are; 2+2 , 3+3 and 1+ 1.
She has to buy both binders and notebooks. So, you have to take into account that she has to have both. The closest you can get to $20 while still getting notebooks, is to buy 4 binders. 4 times 4 equals 16. So, she can get 4 binders and 2 notebooks, because then, 2 times 2 equals 4 and 16 plus 4 equals 20.
Answer: she must complete 4 levels to have a point fewer than 20
Step-by-step explanation:
Given the following :
Starting point = 100 points
Passing a level = - 8 points
Catching a flower = - 3 points
Suppose Tina catches 6 flowers per level
Number of levels she must complete to have fewer Than 20 points
Total number of points lost per level:
Catching 6 flowers = -(6 × 3)
Passing the level = - 8
= - 18 + - 8 = - 26 points
Number of levels she must complete to have < 20
Let number of levels = y
Starting points - (26 × number of levels) < 20
100 - (26y) < 20
100 - 26y < 20
-26y < 20 - 100
-26y < - 80
y > 80/26
y > 3.07
Hence she must complete 4 levels to have a point fewer than 20
