3/13. It reduces by 4. 4 fits into 12 the times and 52 thirteen times.
Answer:
1/4 mile = 3960 ft
Step-by-step explanation:
1 mile = 5280 ft
1/4 = 0.75
0.75 = x
0.75 × 5280 = x
3960 = x
We use the formula: a^2 - b^2 = (a - b )(a + b);
<span>54^2 − 46^2 = (54 - 46)(54 + 46) = 8 x 100 = 800;</span>
Combine like terms: y=5x+4 and y=4x+1. Sub one in: 4x+1=5x+4. -1x=3. X=-3. Sub into other one: y=4•-3+1. Y=-12+1. Y=-11. Check it: -11=5•-3+4. -11=-15+4. -11=-11. So X=-3 and Y=-11 :)
