-4b - 2c =
(-4 × 2.5) - (2 × 3)
-10 - 6
= -16
So, -4b - 2c = -16
Hope this helps and let me know if anymore help is needed!!

➤ How to solve ?
⠀⠀⠀⠀
That's quite easy but you need to recall the BODMAS rule .
⠀⠀⠀⠀
BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction
⠀⠀⠀⠀
In this equation we will solve the bracket then we will apply further BODMAS rule

SolutiOn :
➠ 7x + 31 = 8x - 1 ( 27x + 3 ) -3
➠ 7x + 31 = 8x - 27x - 3 - 3
Now, we will bring the variable on left hand side and constants on right hand side
➠ 7x - 8x + 27x = - 31 - 3 - 3
➠ 26x = -37
➠ x = -37/ 26
➠ x = - 1.42
∴ The value of x is -1.42 .

To find the height you need to take the volume, and the radius (halve the diameter to get the radius) and use the same formula that would be to find Volume and when you plug in the volume and radius you take the radius and solve it with the exponent. Then you take the solved radius and you multiply it with 3.14. After that you then divide the volume by the multiplication.
V=(3.14)(r^2)h
Example:
V=87.92m^3
pi=3.14
r=2m
h=?
87.92=(3.14(2)^2)h
87.92=(3.14(4))h
3.14*4=12.56
87.92/12.56=7
h=7m
Answer:
$800
Step-by-step explanation:
Write 90 out of 120 as a fraction-90/120. Simplify that until you can't any more and you get 3/4 of the original price.
