Answer:
susan´s age=4
jack´s age=31
Step-by-step explanation:
Hello!
To solve the first part of this problem we must propose a system of equations of 2 x2, that is to say two equations with two unknowns where
J = is the age of jack
S = susan's age
with the above the following two equations are inferred
ecuation 1
J=S+27
ecuation 2
(J+5)=4(s+5)
J=4S+20-5
J=4S+15
now to solve we subtract equation 1 from equation 2 as follows
J=4S + 15
-
J=S + 27
___________
0=4S-S+15-27
0=3S-12
![S=\frac{12}{3}=4](https://tex.z-dn.net/?f=S%3D%5Cfrac%7B12%7D%7B3%7D%3D4)
susan is 4 years old
now we use the ecuation number 1
J=S+27
J=4+27=31
jack is 31 years old
b.
Finally, to verify that the answer is correct, we replace the ages of jack and susan in equation 2.
(J+5)=4(s+5)
(31+5)=4(4+5)
36=36
as the equation is the same means that our answer is correct
Jupiter has a diameter of about 88,695 miles (142,800 kilometers) which is more than 11 times the diameter of Earth. It’s volume is over 1,300 times the volume of Earth. This mean that Jupiter is so big that over 1,300 Earth could fit inside of it.
Answer:
=19.81 in²
Step-by-step explanation:
We use the sine formula to find the area of the triangle in question.
In this formula we find the product of two adjoined sides with the sine of the angle between them.
The sides b and c are bound by the angle A.
Therefore area=1/2bcSin A
A=1/2×13.2 in×5.3 in× Sin 34.5
=19.81 in²
