Answer:
joe=6
Sam=11
Step-by-step explanation:
lets see...
i explain 1by1
firstly we know that joe is 5 - 3 x Sam
(read the sentences VERY CAREFULLY)
then, we put Sam as math variable "s"
it will be; 5-3 x S
[tex]5 - 3 \times s[/tex]
the total of their age is 28
[tex]5 - 3 \times s = 28[/tex]
simplify it
it will be 5-S3=28
then you will get 11 right
that will be sam's age
-5 and it will be Joe's age

The opposite of 6 is 6. The absolute value of 6 is 6.
The opposite of 6 is -6. The absolute value of 6 is -6.
The opposite of 6 is 6. The absolute value of 6 is -6.
answer:
the opposite of 6 is -6 and the absolute value of 6 is 6
explanation:
cause its 6 <3
The opposite of the number is -6 and its absolute value is 6.
We have a number - 6.
We have to find out the opposite and the absolute value of the number.
What is the Opposite and Absolute value of a number.For a number - 'n', its opposite is '- n' and the absolute value of a number - 'n' is -
[tex]$n=\left \{ {{n} \;\;\;for \;n > 0\atop {-n}\;\;\;for\;n < 0} \right.[/tex]
We have a number = 6.
The opposite of the number = - 6.
The absolute value of a number = 6.
Hence, the opposite of the number is -6 and its absolute value is 6.

The table shows values for the two functions f and g for different values of x.
What is f(g(0))?
-1

1
This composition is undefined.
Answer:
C.) 1
Step-by-step explanation:
EDG 2020
The value of f(g(0)) is 1.
What is Composition of Functions?Composition of two functions f and g can be defined as the operation of composition such that we get a third function h where h(x) = (f o g) (x).
h(x) is called the composite function.
Given a table which shows values for the two functions f and g for different values of x.
We have to find the value of f(g(0)).
f(g(0)) = f[ g(0)]
From the table, g(0) = -1.
f(g(0)) = f(-1) = 1
Hence the value of f(g(0)) is 1.

Triangle PQR has side lengths 6 cm, 7 cm, and 11 cm. A
triangle with what side lengths would be similar to
triangle PQR?
Select one:
1) 24 cm, 28 cm, 44 cm
2) 3 cm, 5 cm, 9 cm
3) 7 cm, 8 cm, 12cm
4) 24 cm, 21 cm, 33 cm
Answer: the correct answer is 3
The side lengths similar to triangle PQR are 24 cm, 28 cm, 44 cm
What are similar triangles?Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
Given that, a triangle PQR with side lengths 6 cm, 7 cm, and 11 cm.
Considering option 1) 24 cm, 28 cm, 44 cm
To see the similarity, we will check if the ratio of the corresponding sides are equal or not,
6/24 = 1/4
7/28 = 1/4
11/44 = 1/4
That means, 6/24 = 7/28 = 11/44 = 1/4
Since, the corresponding sides of these triangles are in equal ratios,
Hence, The side lengths similar to triangle PQR are 24 cm, 28 cm, 44 cm

Answer:
A =72 in^2
When dilated
=1152 in ^2
Step-by-step explanation:
The area of the triangle is
A = 1/2 bh
We need to convert the units to match
2 ft= 24 inches
A = 1/2 ( 24*6)
A = 1/2 (144)
A =72 in^2
When dilated 6 inches *4 = 24 inches
24 inches *4 = 96 inches
A = 1/2 ( 96*24)
= 1/2(2304)
=1152 in ^2
