Answer:
X= 12
Step-by-step explanation:
Divide 27/3= 9
Multiply 3 from both sides: x-3/-3 * 3 = 9 *3- x * 3
Simplify: -(x-3) =27-x*3
2x=24
Divide 2 from both sides: 2x/2= 24/2
<u>x=12</u>
F(59)=3x-2
f(59)=3(59)-2
f(59)=177-2
f(59)=175
It can be b), c) and d).
b) because it says the sum of three angles — this one’s the most obvious, as we can look at x, y and z as three different angles that sum up to 180.
c) works because 3a is, in essence, a + a + a, which we can look at as the sum of 3 angles that adds up to 180.
d) because we already have 2 angles, and “a” is just an unknown angle. It all sums up to 180.
a) and e) dont work because they involve multiplying (x*y*z and x*x*x) and the problem says we need to look for the sum of angles, not the product. :)
To help solve this problem, create a simple equation.
Let x = weekly allowance.
(x/2) + $4 = $11. Subtract 4 from each side
(x/2) = 7. Multiply each side by 2
x = $14.
Joe's weekly allowance is $14
