Step-by-step explanation:
<u>Step 1: Define</u>
-7 - 3x = 1x + 4(2 + x)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 4: -7 - 3x = x + 8 + 4x
- Combine like terms: -7 - 3x = 5x + 8
- [Addition Property of Equality] Add 3x on both sides: -7 = 8x + 8
- [Subtraction Property of Equality] Subtract 8 on both sides: -15 = 8x
- [Division Property of Equality] Divide 8 on both sides: -15/8 = x
- Rewrite/Rearrange: x = -15/8
Answer:
35
Step-by-step explanation:
- Negative × negative = Positive
- -7 × -5 = 35
I hope this helps!
Really none of the above.
A principal square root of a real number is a positive real number (or a positive real number times i, if you're up to complex numbers, but let's assume not.) It's not necessarily a positive integer, √2 being the obvious example.
Is √2 a positive fraction? We can write it as √2 / 1 so I suppose it is. It's certainly not a rational number. Even if we grant irrationals as fractions surely √0=0 isn't a positive fraction. So "always" isn't correct.
I'd go with none of the above, but if I had to choose I'd choose D.
Answer:
You would be required to pay $587.50
Step-by-step explanation:
Divide $1762.50 by three:
You get $587.50
To find how much you have left:
Subtract 587.50 from 668.72:
You'd be left with
