Question

100 POINTSSS Please help me guys. Im begging you.

Answer 1

Para resolver proporciones necesitas cruzar multiplicar. El error es que ella multiplicó los numeradores y luego los denominadores. Para resolver correctamente deberías multiplicar 3.5 • 12 y 5 • x. Esto daría como resultado 42 = 5x. Entonces dividirías 5 de ambos lados para obtener x = 8.4

Espero que esto ayude <3

Answer 2

To solve proportions you need to cross multiply. The error is she multiplied the numerators and then multiplied the denominators. To solve correctly you would multiply 3.5 • 12 and 5 • x. This would result in 42 = 5x. Then you would divide 5 from both sides to get x=8.4

Hope this helps :)
