Decimal Wise: 0.5 (1 divided by 2)
Percentage Wise: 50% (Multiply The Decimal version by 100)
Let F be the price of Fly-boys and S be the price of spinners.
S= 1/3 x F
3 = 1/3 x F
F = $9
Answer:
x = (3 + 8y) / (y - 1)
Step-by-step explanation:
y = (x + 3) / (x - 8)
Make x the subject
y = (x + 3) / (x - 8)
Cross product
y * (x - 8) = (x + 3)
xy - 8y = x + 3
xy - x = 3 + 8y
Factorize the left hand side of the equation
x( y - 1) = 3 + 8y
Divide both sides by (y - 1)
x = (3 + 8y) / (y - 1)
Answer:
Step-by-step explanation:
- <em>During a mathematics activity, teacher Julieta distributed to each of her students 4 straws measuring 2 cm, 3 cm, 7 cm and 8 cm. In this activity, Julieta's students had to build triangles with these straws, without cutting them.
</em>
- <em>How many different triangles could each of Julieta's students form with these straws?</em>
==========================================================
- <em>Triangle inequality theorem says that no any side of a triangle can be longer or equal to the sum the other two sides</em>
<u>Given measures:</u>
<u>We see that:</u>
Therefore we can't make triangles with the sides of 2 cm, 3 cm and 7 cm or 8 cm
<u>Possible solutions are:</u>
- 2 cm, 7 cm, 8 cm
- 3 cm, 7 cm, 8 cm
So we can make two different triangles
