Answer:
The sum of X divided by 4 and 8 is -16.
Step-by-step explanation:
The main numbers we are adding are X/4 and 8, so those can be referred to as "the sum of". X/4 is simply "X divided by 4".
This all equals -16, so we have:
The sum of X divided by 4 and 8 is -16.
Answer:
Angeline will spend $70.77
Step-by-step explanation:
y = 8.09(5) + 3.79(8)
y= 30.32 + 40.45
y = 70.77
An expression for the distance Scott threw the javelin is, x = 3y
For given question,
Let x be the distance for Scott threw the javelin and y be the distance for Daniel threw the javelin.
We have been given a statement 'Scott threw the javelin 3 times farther than Daniel threw the javelin.'
We need to write given statement as a mathematical expression.
First we rewrite given statement as,
Scott threw the javelin 3 times farther than Daniel threw the javelin.
the distance Scott threw the javelin is 3 times the distance Daniel threw the javelin
⇒ x = 3 × y
Therefore, an expression for the distance Scott threw the javelin is,
x = 3y

We must know that the are of the triangle is given by definition by
A = (1/2) * (b) * (h)
where
b = base
h = height
Substituting the values
A = (1/2) * (x) * (1 + 6x)
A = (1/2) * (x + 6x ^ 2)
Since the area is 13 then
(1/2) * (x + 6x ^ 2) = 13
Clearing x we have
6x ^ 2 + x = 26
6x ^ 2 + x-26 = 0
(x-2) * (x + 13/6) = 0
As we look for the base of a triangle then x> 0
x = 2
answer
the base is x = 2
6x ^ 2 + x = 26
