Answer:
75 cm
Step-by-step explanation:
the ratio of centimeter to miles is 2:10 or 1:5 (1 cm = 5 mi)
this ratio can be changed to a fraction (1/5)
so now we can set up this equation:
(1/5) = (x/375)
where x = cm on the map
if it makes it easier to understand:
(1cm/5mi) = (xcm/375mi)
now we solve for x:
375(1/5) = x
x = 375/5
x = 75 cm
Answer:
k=-1/5
Step-by-step explanation:
1/2(10k-16)+11=-2
5k-8+11=2
5k+3=2
5k=-1
k=-1/5
Answer:
625
Step-by-step explanation:
250/6 =41.6666666667
41.6666666667x15 = 625
<span>X(x^2-6x+5)=12(x-5)
Distribute
x^3-6x^2+5x=12x-60
Simplify (minus 12x from both sides)
x^3-6x^2-7x=60
Factor X
x(x^2-6x-7)=60
Divide X from btoh sides
</span><span>(x^2-6x-7)=60/x
Simplify
X=7.861308
