2.4 miles
cross multiple 3/25 x x/20
25x=60
x = 60/25 simplified is 2 2/5 or 2.4 miles
Each of the 4 girls will get 3 marbles with 1 left over.
If 4 girls get 3 marbles each, that is 4 times 3. This is 12. Now since there are 13 marbles, we know that there is 2 left over because 13-12 is 1.
Answer:
2 1/4
Step-by-step explanation:
=−514+712
Rewriting our equation with parts separated
=−5−14+7+12
Solving the whole number parts
−5+7=2
Solving the fraction parts
−14+12=?
Find the LCD of 1/4 and 1/2 and rewrite to solve with the equivalent fractions.
LCD = 4
−14+24=14
Combining the whole and fraction parts
2+14=214
Answer: 2(3x+4)
Explanation:
We would use the distributive property to multiply 2 by 3x, then again by 4, which gives us 6x+8.
