Answer: <em>P (ringers)</em>
Step-by-step explanation:
<em>This probability is simplified from 4/10 to 2/5</em>
<em>Since he got 4 ringers out of 10 attempts</em>
<em>we can tell that this probability stands for Ringers</em>
Answer:
-18*5 is you answer aka -90
Since we can add a number to a tens number easily, we make one of the addends a tens number when solving an addition problem.
Example 1:
Add 9 and 6.
9 + 6 = 9 + (1 + 5)
= (9 + 1) + 5
= 10 + 5 = 15
Note that adding 10 and 5 is much easier than adding 9 and 6.
Example 2:
Add 18 and 16.
18 + 16 = 18 + (2 + 14)
= (18 + 2) + 14
= 20 + 14 = 34
Note that adding 20 and 14 is much easier than adding 18 and 16.
Answer:
40
Step-by-step explanation:
8+8+8+8+8=5x8
5x8=40
Answer: (1,4)
Step-by-step explanation:
2x - 3y = -10
y = 4x
2x - 3(4x) = -10
2x - 12x = -10
-10x = -10
x = 1
y = (4)(1)
y = 4
Double Check:
2(1) - (3x4) = -10
2-12 = -10
-10 = -10
