Answer:
a=30
b=15
c=3
d=30
e=10
Step-by-step explanation:
Solve for A first and continue solving for one variable at a time
2x 4 =- 8
2 x + 4 = 8 2x+4=8 2x+4=8. Subtract 4 from both sides. Simplify 8 − 4 8-4 8−4 to 4. Divide both sides by 2.
Answer:
The domain is the interval [5,∞)
Step-by-step explanation:
we have
we know that
The radicand (number under a radical) must be greater than or equal to zero
so
solve for x
Adds 5 both sides
therefore
The domain is the interval [5,∞)
All real numbers greater than or equal to 5
Answer:
$60
Step-by-step explanation:
Let x represent the initial money she had
She spent 3/5 of her money on a bag, That is;
3/5 of x
= 3/5 * x
and 1/6 of x on a belt
Therefore, the total money she spent is
3/5 * x + 1/6 * x
She had $14 left after all her purchases
To find how much she had left, sum up all her spending and what she has left
3/5 * x + 1/6 * x + 14 = x
collect like terms
3/5 x + 1/6 x - x = -14
23/30 x -x = -14
-7/30x = -14
x = $60
