b+2(b+2b) = b+2(3b) Adding the like terms b and 2b

=b+6b

=7b

Option b is :

3b+b = 4b (Like terms can be added)

5. Henry hit 3 more than half as many home runs as Jack hit last season. Henry hit a total of 8 home runs. a. Make Sense and Per

Evgesh-ka [11]

Answer:

a. $3+\frac{x}{2} =8$

b. x = 10

Step-by-step explanation:

a. The number of home runs hit by Jack last season = x

It is given that Henry hit 3 more than half as many home runs as Jack hit.

Half of the runs hit by Jack = $\frac{x}{2}$

3 more than half the runs = $3+\frac{x}{2}$

So, the number of home runs hit by Henry = $3+\frac{x}{2}$

But, it is given that Henry hit a total of 8 runs.

Therefore, $3+\frac{x}{2} =8$

b. $3+\frac{x}{2} =8$

Subtract 3 from both sides.

$\frac{x}{2} =8-3$

= 5

x = 5 × 2

= 10

Hence, Jack hit 10 runs in the last season.
