Answer:
The two numbers are:
8 and 13
Step-by-step explanation:
a = 2b - 3 Eq. 1
a + b = 21 Eq. 2
Replacing Eq. 1 in Eq. 2:
(2b-3) + b = 21
3b - 3 = 21
3b = 21 + 3
3b = 24
b = 24/3
b = 8
from Eq. 1
a = 2*8 - 3
a = 16 - 3
a = 13
Check:
From Eq. 2:
a + b = 21
13 + 8 = 21
Answer:
12 in³
Step-by-step explanation:
Its made up of 12 (4×3 = 12) cubes of 1 in³ each
So 12 × 1 = 12 in³
Answer:
Step-by-step explanation:
Here we have the curve xy =6 bounded by the line y=2, y=6 and x=6.
This region is rotated about x =6
We have to find the volume
Since rotated about vertical line parallel to y axis, shifting y axis to right by 6 units we get
the curve equation as
(6-x)y=6
6y-6xy =6
6xy =6(y-1)
x = (y-1)/y
and limits for y is 2 to y
Volume = 
Substitute limits
Volume = 
Answer:
Q 5.9
Step-by-step explanation:
Que el dinero gastado por Juan sea x
Deja que el dinero gastado por Carolina sea y
Si el dinero total gastado es Q 15
Luego;
x + y = 15 ------- (1)
De la segunda oración;
y = x + 3,2 -------- (2)
Sustituyendo (2) en (1)
x + x + 3,2 = 15
2x + 3,2 = 15
2x = 15 - 3,2
2x = 11,8
x = 5,9
x = Q 5.9
Por lo tanto Juan gastó Q 5.9
