- a • [- b] = c
[a] • [- b] = - c or [-a] • [b] = - c (either one is fine)
[- c] / - b = a
[- c] / [b] = - a
(85 + 84 + 78 + x) / 4 = 86
(247 + x) / 4 = 86
247 + x = 86 * 4
247 + x = 344
x = 344 - 247
x = 97 <=== her score was 97
Answer:
Option C
Step-by-step explanation:
Given
Total length of ribbon lucy has=4 inches
She wants to divide it into 6 equal sized pieces so
Length of each piece=4/6
This can also be written as:
Length of each piece=4*(1/6
)
Now we will look at the options one by one:
For A, Each piece has 6/4 inches of ribbon.. This statement is not true as we have to divide 4 inches into 6 pieces so 4 is supposed to be in the numerator.
For B, breaking down 4/6 gives us 4*(1/6), so the statement is not true.
For C , as we can see that the expression is 4*(1/6), each piece will have 1/6 of inches of ribbon.
So option C is the correct answer..
Answer:
i think your question is missing something??
Step-by-step explanation:
3(4) + 6 = 7 (2(4)-3)
12 + 6 = 7 (8-3)
18 = 7 (5)
18 = 35?
