Answer:
Q6: 5 times the sum of 3 and 4, then subtract 4.
Q7: Add 8 to half the difference of 6 and 2, then subtract 1.
Step-by-step explanation:
Question 6:
[tex]5 \times (3 + 4) -4[/tex]
• First of all, we can see that 5 is being multiplied by something, so we can say "5 times...".
• Next we see that the 5 was being multiplied by the sum of 3 and 4, so we can combinedly say "5 times the sum of 3 and 4...".
• And finally, we see that 4 is taken away from the result. Therefore we can say " 5 times the sum of 3 and 4, then subtract 4".
Question 7:
[tex]8 + \frac{1}{2} \times (6-2) -1[/tex]
• Firstly, we can see that 8 is being added to something, so we can say "Add 8...".
• Next, we see that 8 was being added to [tex]\bf \frac{1}{2}[/tex] of something, so we can combinedly say "Add 8 to half of...".
• Then we see that the difference (i.e., result of subtraction) of 6 and 2 was being halved. Therefore we say "Add 8 to half of the difference of 6 and 2...".
• Finally, we can see that 1 is subtracted from the result. Therefore, we can say "Add 8 to half of the difference of 6 and 2, then subtract 1".
