<span>Understand that:
• the sum of two positive numbers is greater than either
number.
Understand that addition is the inverse of subtraction (addition
reverses subtraction and vice versa) and use this to check
results.
Respond rapidly to oral or written questions, explaining the
strategy used. For example:
• 654 add 50… Add 68 to 74…
• 7 add 12 add 9… Add 15, 6, 4, 15 and 1…
• What is the sum/total of 26 and 39? And of 13, 62 and 3?
• How many altogether are 121 and 35? And 61, 37 and 6?
• Increase 48 by 22.
• Which three numbers could have a total of 103?
Are there any others?</span>
Answer:
A y = 3x
Step-by-step explanation:
We can check each line to see if the point is on it
A y = 3x 6 = 2*3 6=6 this is true so the point is one the line
B y = 4-x 6 = 2-4 6 = -2 false
C y = -3x 6 = -3(2) 6=-6 false
D y =-x+4 6 = -2+4 6 = 2 false
What is the question you have?
The answer is C! Sorry if u get it wrong or I’m too late
Answer: d
Step-by-step explanation: formula is 1/2bh 14 times 6 is 84 divided by 2 is 42
