Answer:
She spent 17 books
Equation: 45+6 = 51 and 51/3 = 17 books
3.92/2.8=1.4
Unless it’s reverse.
2.8/3.92=0.714285714285 and so on.
Answer:
For question 1 it's B
For question 2 it's C
Step-by-step explanation:
<u>For question 1, you have to apply the "Triangle Inequality Theorem"</u>
A+B > C
B+C > A
A+C > B
Let's say that A=22, B=17, C= 14
22+17 > 14 True
17+14 > 22 True
22+14 > 17 True
Therefore, the answer is B
<u>For question 2, you apply the rule of the sum of the triangles which is 180°</u>
70+70+? = 180
140+? = 180
? = 40
Therefore, it's C
Times the ones in () which becomes 120 * 224 = 0.535
