PEMDAS comes first. Instead of adding 9+2 first, they should've multiplied 2x3. The final answer would be 15.
Answer:
230°
Step-by-step explanation:
1. A quadrilateral is a 4-sided shape that consists of 2 triangles.
2. The interior angles in a triangle equal 180°: a quadrilateral has interior angles of 360°.
3. x° + 25° + 45° + 60° = 360°
4. x° + 130° = 360°
5. x° = 230°
Answer:
72.66 calories
Step-by-step explanation:
1. find 1g of bannana = calories
86÷100g = 0.86 calories
1g of bannana = 0.86 calories
2 find 1g of yougurt = calories
89÷100g = 0.89 calories
1g of yougurt = 0.89 calories
3. 70g of bannana= 70×0.86
= 60.2 calories
4. 14g yogurt= 14×0.89
= 12.46 calories
5. 60.2 calories +12.46 calories = 72.66 calories
Answer:
x=9.1
Step-by-step explanation:
