Ms. Link’s recipe calls for 4 times as many peas as onions. If she uses 2 cups of onions, how many cups of peas will she need?
4 × 2 = 8 cups of peas
Answer:
Number of cups of peas she needs = 8.
Explanation:
Ms. Link’s recipe calls for 4 times as many peas as onions.

Question 3.
Luis biked 455 yards today, and Alex biked 298 yards. If Alex bikes 475 yards tomorrow, how far will Luis bike if they increase their length by the same amount?
Answer:
Number of yards Luis biked tomorrow = 930.
Explanation:
Number of yards Luis biked today = 455.
Number of yards Alex biked = 298.
Number of yards Alex biked tomorrow = 475.
If they increase their length by the same amount;
Number of yards Luis biked tomorrow = Number of yards Luis biked today + 475
= 455 + 475
= 930.
