Answer:
a=-8/5
Step-by-step explanation:
(-1/2a-5)=3a+1
To find the opposite of 1/2 a−5, find the opposite of each term.
-1/2a-(-5)= -3a+1
The opposite of −5 is 5.
-1/2a+5=-3a+1
add 3a to both sides
-1/2a+5+3a=1
Combine-1/2and 3a to get 5/2a
5/2a+5=1
Subtract 5 from both side
5/2a=1-5
Subtract 5 from 1 to get −4.
5/2a=-4
Multiply both sides by 2/5 =0.4, the reciprocal of 5/2=2.5.
a=-4x(2/5)
express -4x(2/5)=1.6 as single fraction.
a= -4x2/5
Multiply −4 and 2 to get −8.
a=-8/5
Fraction −8/5 ≈−1.6 can be rewritten as −8/5 =−1.6 by extracting the negative sign.
a=-8/5
Answer:
C
Step-by-step explanation:
(4,200 - 725) + 215 + 375 = 4065

Answer:
There the buoy is 17.3 m from the place where the diver started.
Step-by-step explanation:
a² + b² =c²
⇒ 10² + b² = 20²
⇒ 100 + b² = 400
⇒ b² = 400 - 100
⇒ b²= 300
⇒ b = 
⇒ b = 17.3 m
There the buoy is 17.3 m from the place where the diver started.
Answer:
1. -5
2. 8
3. -11
Step-by-step explanation:
In quadratic equations, ( 
) C is always the y-intercept. In these equations, C is -5, 8, and -11.
So, the y-intercepts are -5, 8, and -11.
You put the -16 - 7 in parenthesis and then the 4 infront of that. So the equation will look like 4(-16 - 7) = -92
