Answer: 4 9/10
Step-by-step explanation: You need to subtract 12 2/5 and 7 1/2.
The two fractions have different denominators. Multiply to find a common denominator
2/5 x 2/2 = 4/10
1/2 x 5/5 = 5/10
Now you have 12 4/10 minus 7 5/10. But you cannot subtract 4/10 and 5/10 equally.
Subtract 12 - 1 and add 1 to 4/10.
12 - 1 = 11
10/10 (10/10 is 1) + 4/10 = 14/10
Now you have 11 14/10 minus 7 5/10. Subtract.
11 - 7 = 4
14/10 - 5/10 = 9/10
That makes 4 9/10.
Hope this is helpful :)
Answer:
NATHAN RODE 2 MILES
Step-by-step explanation:
Let N = Nathan's number of miles
Let M = 5N - 4 (Miguel rode his bicycle 4 miles less than 5 times the number of miles Nathan rode.
M = 6 (Miguel rode his bicycle 6 miles.)
6 = 5N - 4 (Substitute 6 for M in the equation above(M = 5N - 4).
6 + 4 = 5N - 4 + 4 (Add 4 to both sides of equation.)
10 = 5N
10/5 = 5N/5 (Divide both sides by 5 to isolate the variable N.)
2 = N
ANSWER: NATHAN RODE 2 MILES

DOES MIGUEL'S 6 MILES EQUAL 5N - 4?
5N - 4 = (5)(2) - 4 = 10 - 4 = 6 MILES .
YES IT DOES.
Answer:
3/4
Step-by-step explanation:
As a decimal, 75% is 0.75, which is 3/4
Radius of Amy cake = 6 in .
Area of circle can be found by the formula A=
Where r is radius of circle and π = 3.14
Substituting the values of r and π Area of top of cake = 3.14
=113.04 square inches .
Amy divides the cake in 10 parts.
Area of each piece=113.04÷10=11.304 square inches.
Area of each piece = 11.3 square inches(rounded to nearest tenth.)
