Answer:
L(1-0.15)
L-(15/100)L
Step-by-step explanation:
we know that
100%-15%=85%
85%=85/100=0.85
so
The number of hours that Mateo spent at the beach last week is equal to the hours that landen spent at the beach (L) multiplied by 0.85
The linear equation that represent this situation is
0.85L
<u><em>Equivalent expressions are</em></u>
1) L(1-0.15)
Because
Applying distributive property
L(1-0.15)=L-0.15L
Combine like terms
L-0.15L=0.85L
2) L-(15/100)L
because
15/100=0.15
substitute
L-(15/100)L=L-(0.15)L=0.85L
a) All three athletes accelerated because the slope of every line in the beginning in positive.
b) Dash decelerated towards the end because the slope of the line representing him becomes negative.
c) Flash maintained a constant speed because the slope of his line does not change.
d) Krash's line is horizontal because he did not move for that time.
e) Flash won the race because his line reaches 100 first.

Answer:
12∠x∠16
Step-by-step explanation:
For the triangle to be acute,a²+b²+c²,
Where c is the largest side of the triangle.
Hence, we must say x²+(x+4)²≥20²,
or after simplifying, x²+4x-192≥0 or (x+16)(x-12)≥0
Since x must have positive values only, x≥12
Therefore, for the triangle to be acute,we must have 12≤x≤16.
