An equation is formed of two equal expressions. The value of 'a' in the given equation is 6.452.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The given equation can be solved for 'a' as shown below,
0.75a = 10 - 0.8a
0.75a + 0.8a = 10
1.55a = 10
a = 6.452
Hence, the value of 'a' in the given equation is 6.452.

Answer:
C
Step-by-step explanation:
6(a+b) + 2z = -8 ; divide by 2
3(a+b) + z = -4
a+b+z = 2; subtract z from both sides
a+b = 2-z; substitute a+b into equation 3(a+b) +z = -4
3(2-z) +z = -4; distribute
6 - 3z+ z= -4 ; subtract 6 on both sides
-3z + z = -4 -6 ; combine like terms
-2z = -10; divide both sides by -2
z= 5
3(a+b) +z = -4; substitute z by 5
3(a+b) +5 = -4; subtract 5 from both sides
3( a+b) = -4 -5; combine like terms
3(a+b) = -9; divide both sides by 3
(a+b) = -3
Answer:
7.4162
Step-by-step explanation:
Lets first number is x, so second number is (x+32).
The sum of these numbers is 186 so
x+(x+32)=186
2x+32=186
2x=154
x=77
second number is x+32=77+32=109
Answer: numbers are 77 and 109
