Answer:
60 years
Step-by-step explanation:
Given that :
Sarah's age = a
Assume Sarah is older than 44 ; then a > 44
64 = 4 times difference between a and 44
Expressing the problem mathematically ;
64 = 4 * (a - 44)
64 = 4a - 176
64 + 176 = 4a
240 = 4a
a = 240 / 4
a = 60
Hence, Sarah is aged 60
The answer should be a segment. have a great day :)))
Answer:
the expressions are not equivalent
Step-by-step explanation:
7(x+2y) (distribute 7 into the parentheses)
= x(7) + 2y(7)
= (7x + 14y) ≠ (14x + 14y)
hence the expressions are not equivalent
Answer:
Step-by-step explanation:
Given
Required
Determine the length of a
Solve for c in
Substitute and in
Solve for 4b
Solve for b
Recall that:
B, is the correct answer.
7% of 450 is 31.5
We add 31.5 to 450 to find out highest possible error, and subtract 31.5 from 450 to find out lowest possible error.
