Answer:
13.5
Step-by-step explanation:
The point with the missing coordinate is (?, 12), so the value of y is 12. Plug 12 into the equation in the place of y.
4x - 3(12) = 18
4x - 36 = 18
4x = 54
x = 54/4 = 13.5
The answer is A because you have to use the process of substitution
Answer:
r=-10
Step-by-step explanation:
Plug in the value of t into the equation.
r=3t-1; t = -3
r=3(-3)-1
r= -10
Answer:
The volume of water and air inside each of the plastic ice cubes is 3000mm³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, rectangular pyramid.
The volume of a rectangular pyramid is expressed as
V=(l*w*h)/3
Given data
Length l = 20mm
Width w= 15mm
Height h= 30mm
Substituting our given data we have
V= 20*15*30/3
V= 9000/3
V= 3000mm³
