Answer:
x = -19
Step-by-step explanation:
-10x - 19 = 19 - 8x
-10x + 8x = 19 + 19
-2x = 38
x = -19
Answer:
28.4in³
Step-by-step explanation:
Volume of the square based pyramid = L²H/3 where;
L is the length of a side of the square base
H is the height of the prism
Given
Perimeter of the base = 13.4 in
Height of the pyramid = 7.6in
First we need to get the length of the square base
Perimeter of a square = 4L
13.4 = 4L
L = 13.4/4
L = 3.35 in
Next is to find the required volume of the pyramid
V = L²H/3
V = 3.35²(7.6)/3
V = 85.291/3
V = 28.4 in³
Hence the volume of the pyramid to nearest tenth is 28.4in³
Ax+by=c
y+4= -1/3(x-12)
remove ( )
y+4= -1/3x+4
subtract 4
y=-1/3x+0
add 1/3x
1/3x+y=0
hope this helps
Answer:
m=33
Step-by-step explanation:
12.95 + (0.25 x m)= 21.20
12.95 + 0.25m= 21.20
0.25m= 21.20-12.95
0.25m=8.25
Divide both side by 0.25
0.25m/0.25=8.25/0.25
m=33
