Answer:a=4
Step-by-step explanation:
Simplifying
4a + -5 + 2a + 9 = 28
Reorder the terms:
-5 + 9 + 4a + 2a = 28
Combine like terms: -5 + 9 = 4
4 + 4a + 2a = 28
Combine like terms: 4a + 2a = 6a
4 + 6a = 28
Solving
4 + 6a = 28
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + 6a = 28 + -4
Combine like terms: 4 + -4 = 0
0 + 6a = 28 + -4
6a = 28 + -4
Combine like terms: 28 + -4 = 24
6a = 24
Divide each side by '6'.
a = 4
Simplifying
a = 4
Answer:
no of hours worked by Kcee = 16 hours
no. of hours worked by Kcee = 22
no. of hours worked by Atiana = 88
Step-by-step explanation:
Let the no. of hours worked by Alberto be x
given that
Kcee worked 6 hours more than Alberto
no. of hours worked by Kcee = x + 6
Given
Atiana worked 4 times as many hours as Kcee
no. of hours worked by Atiana = 4*no. of hours worked by Kcee
no. of hours worked by Atiana = 4*(x + 6) = 4x + 24
Total hours worked by them together in terms of x = x + x + 6 + 4x + 24
Total hours worked by them together in terms of x = 6x + 30
As given Together they worked 126 hours
6x + 30 = 126 hours
6x = 126 - 30
6x = 96
x = 16
Thus, no of hours worked by Kcee = x = 16 hours
no. of hours worked by Kcee = x + 6 = 16 + 6 = 22
no. of hours worked by Atiana = 4x + 24 = 4*16 + 24 = 64 + 24 = 88
Answer:
It would be o.6 for the first one because i divide 22 with 33 and i got that answer
Step-by-step explanation:
Answer:
Step 1: simplify 3/4
(3/4 • a) - 16 = 0
Rewrite the whole as a fraction using 4 as the denominator
16= 16/1 = 16 * 4/4
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible
3a - ( 16 *4 ) / 4 = 3a - 64 / 4
Step 2: 3a - 64 / 4 = 0
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiply's both sides of the equation by the denominator.
3a - 64 / 4 * 4 = 0 * 4
Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
3a - 64 = 0
Solving Single Variable Equation
Solve : 3a-64 = 0
Add 64 to both sides of the equation :
3a = 64
Divide both sides of the equation by 3:
a = 64/3 = 21.333
