Answer:
a) and e)
Step-by-step explanation:
7 * 1/2 = 3.5
3.5 / 2 = 1.75
? = 1.75
a) 2 * 1.75 = 7 * 1/2 (correct!)
b) 7 * 1/2 * 1.75 = 2 (wrong!)
c) 2 * 7 * 1/2 = 1.75 (wrong!)
d) 1.75 * 7 * 1/2 = 2 (wrong! this is the b) backwards)
e) 1.75 * 2 = 7 * 1/2 (correct! this is the a) backwards)
Answer:
Step-by-step explanation:
By geometric mean theorem,
In a triangle ABC,


y² = 60
y = √60
y = 7.75
Similarly, 

x² = 40
x = √40
x = 6.32
Answer:
-2/4 = w
Step-by-step explanation:
4w + 2 when you isolate the variable, you subtract the 2, then you have to divide by 4 so that would give you -2/4 = w.
Answer:-1 over 2.
Step-by-step explanation:
In order to find the total number of roses, we can use multiplication. Since there are 6 roses on each bush, we can say that the answer is: 6+6+6+6+6+6+6+6+6+6. Since multiplication is a way to quickly add the same number, we can use 6*10. This becomes 60.
Good luck :D
