Answer:
114
Step-by-step explanation:
so lets call shelf 1 x
shelf 2 is twice size + 18 of shelf 1 so it is 2(x)+18
shelf 3 is 12 less than shelf 1 so x-12
shelf 4 is four more so x+4
Add them all together and it should be 5x+10= 2.5 m or 250 cm
Solve for x using cm
then plug into shelf 2 equation
Answer:
x^2 - 6x - 55 = 0
using calculator apply mode 5 3 and write nmbrs
1 , -6 , -55
answers must be 11 and -5
a=16 b=28
this is because you can use the ratio to make the equation 4x+7x=44 which turns to 11x=44 and that simplifies to x=4 so to get a you multiply 4 and 4 or a=4*4 and to get b you multiply 7 and 4 or b=7*4 so a=16 and b=28
Answer:
The answer is x=-8
