Answer:
= 2(2x + 5)
Step-by-step explanation:
Given that:
= (7x + 5) - (3x - 5)
By simplifying
"-" sign before bracket will alter the inner signs
= 7x + 5 - 3x + 5
Adding like terms
= 4x + 10
By taking 2 common we get:
= 2(2x + 5)

<span>0.75 (1/2x) = 60
60/3 is 20, which is 25% of her remaining money,
So her total remaining money is $80.
Then 80 x 2 = 160</span>
Answer:
Step-by-step explanation:
olve the line equation for y
:
y = -ax/2 +5
:
therefore, the y-axis intercept is 5
:
area of triangle = (1/2) * base * height
:
(1/2) * base * 5 = 10
:
base = 4 which is the x-axis intercept
:
-a(4)/2 +5 = 0
:
-2a = -5
:
a = 5/2

Answer:
15.36 feet
Step-by-step explanation:
We solve the above question using Trigonometric function of Tangent
Tan θ = Opposite /Adjacent
From the question
θ = 38°
Opposite = the height of the chair = 12 feet tall
Adjacent = the distance from the base of the lifeguard's chair to the swimmer = x
Hence:
tan 38° = 12/x
Cross Multiply
tan 38° × x = 12
x = 12/tan 38°
x = 15.359299586
x ≈ 15.36 feet
Hence, the distance from the base of the lifeguard's chair to the swimmer is 15.36 feet
