You can either convert -3 into a fraction, or convert -2/5 into a decimal so you can solve this.
If you decide to convert -3, into a fraction, it would be -3/1, and you'd have to multiply that by the reciprocal of -2/5.
So, you'd have -3/1(-5/2)=15/2, which can be simplified to 7 1/2.
If you decide to convert -2/5 into a decimal, you would get -0.4. You would then divide -3 by -0.4, which is equal to 7.5.
Both 7.5 and 7 1/2 are correct answers, and if you were to convert 7.5 into a fraction and 7 1/2 into a decimal, you would notice that they are the same number, but in different forms.
3.5 * 3.5 = 12.35. Each of Benji's pieces would be 12.35 cm^2
$16 per month can be changed to 16m where m represents months.
The $2 per Pilates class can be 2p where p represents Pilates classes.
An equation of y = 16m + 2p can be set up, where y represents how much McKenna is charged total for gym membership ($52)
52 = 16m + 2p
We know that McKenna attended 12 Pilates classes, and we also know that McKenna attended 1 month, so we plug this in:
52 = 16(1) + 2(12) (simplify)
52 = 16 + 24 (add 24)
52 = 40
Since this is not equal, $52 is not the correct amount to be charged.
1/9
because there are 21 chips in the bag 7 of them are yellow so 7/21
but you draw twice so you square it (7/21)^2=1/9
Answer:
x = 6
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Geometry</u>
- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up equation</u>
(8x + 2) + 70 + 60 = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 8x + 132 = 180
- Isolate <em>x</em> term: 8x = 48
- Isolate <em>x</em>: x = 6
