Answer: It isnt equivalent.
Step-by-step explanation:
(8*7)+7
56+7
=63
48+7
=55
63 is not equal to 55
in that case... (8*7)+7 doesnt even equal to 48+7 in the first place.
C, because if it was D, they would be the same, which is A written in another format. Then process of elimination
Let the two numbers be x and y, then
x + y = 62 . . . . . . . (1)
x - y = 18 . . . . . . . .(2)
subtracting (2) from (1), we have:
2y = 44
y = 22
From (2), x + 22 = 62
x = 62 - 22 = 40
therefore, the two numbers are 40 and 22.
Answer: 3/4
Step-by-step explanation: Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the divison sign to multiplication and flip the second fraction.
So here, 3/8 divided by 1/2 can be rewritten as 3/8 × 2/1.
Now we are simply multiplying fractions so we multiply across the numerators and we multiply across the denominators.
So we have 3 × 2 which is 6 and 8 × 1 which is 8. Since 6/8 is not in lowest terms, we divide the numerator and the denominator by the greatest common factor of 6 and 8 which is 2 and we get the equivalent fraction 3/4.
Therefore, 3/8 divided by 1/2 is 3/4.
