10+5=15, so 7+10=17

10+5=15, so 7+10=17

10+5=15, so 8+7=15

10+5=15, so 8+7=15

10+4=14, so 7+7=14

10+4=14, so 7+7=14

10+5=15, so 6+9=15

Based on the description you provided, we need to analyze the ten frame and the counters to determine which equations are appropriate.

  • The ten frame contains 8 red counters and 2 yellow counters, which totals to 10 counters in the frame.
  • Below the ten frame, there are 5 yellow counters.

From the information depicted:

  1. The total number of counters in the situation can be represented as: \[ 10 \text{ (in the frame)} + 5 \text{ (below the frame)} = 15 \]

Now let's evaluate the equations given in the response options:

  • \(10+5=15\) is true.
  • The remaining parts of the equations should equal 15 as well in relation to the 10 counters in the frame.

Evaluating the second parts of the equations:

  • \(7+10=17\) (not equal to 15)
  • \(8+7=15\) (this is true as it also equals 15)
  • \(7+7=14\) (not equal to 15)
  • \(6+9=15\) (this is true as it also equals 15)

So, the equations that match what the model shows are:

  • \(10+5=15, \text{ so } 8+7=15\)
  • \(10+5=15, \text{ so } 6+9=15\)

Thus, the final response should include:

  • \(10+5=15, \text{ so } 8+7=15\)
  • \(10+5=15, \text{ so } 6+9=15\)
