Answer:
I think it's the third one sry if I'm wrong
You don't need a calculator for everything!
Think about it this way: We know 20=2x10, so 7 divided by 20=7/(2x10), which we can solve as 7/10/2. 7/10=0.7, then all we have to do is divide 0.7 by 2. Well we know 0.6/2 is 0.3, so 0.7 divided by 2 is 0.35.
So 0.35 is your answer :)
Answer:
$48.33
Step-by-step explanation:
1. Find the amount of the sales tax by multiplying the tax percentage by the sales price.
$45 × 7.4% = $3.33
2. Add the amount of the sales tax back to the sales price.
$45.00+$3.33 = $48.33
Answer:
No solutions: 3x + 1 = 3x + b, where b ≠ 1
Infinite solutions: 2x - 4 = 2x - 4
Step-by-step explanation:
For an equation to have <em>no </em>solutions, it has to reduce to an equation that's never true. For our given equation, this means we'll need to fill in the blank with some value other than 1. If we pick 2, for instance, we'll get the equation 3x + 1 = 3x + 2, which reduces to 1 = 2, a false statement. No value of x will make the equation true.
To have <em>infinite </em>solutions, on the other hand, we need an equation that is <em>always</em> true. Filling in the blank with 4 here will give us one: 2x - 4 = 2x - 4 reduces to -4 = -4, a statement that is always true.
