Answer:
3 and 8
Explanation:
3a + 5b = 49
2b = 5a + 1
thus:
2b - 5a = 1 equation 1
-5a + 2b = 1 equation 2
therefore:
multiplying equation 2 by -2.5 and adding to equation 1:
3a + 5b = 49
12.5a - 5b = -2.5
15.5a + 0 = 46.5
15.5a = 46.5
a = 46.5/15.5
a = 3
2b = 5a + 1
2b = (5*3) + 1
2b = 15 + 1
2b = 16
b = 16/2
b = 8
Verification:
3a + 5b = 49
3*3 + 5*8 = 49
9 + 40 = 49
In the Spanish language, changing the order of words is unnecessary. As this exercise requests a modification in that order, we will follow straightforward steps to achieve it. We will turn declarative sentences into questions in Spanish.
1) Start with a standard declarative statement: Regular sentences in Spanish have the subject first, followed by the verb.
2) Swap the subject and the verb's positions: In English, when you say this is... in declarative form you would ask is this...? in an interrogative form. The same rule applies in Spanish. For example, you change ésta es... to ¿es ésta...? This adjustment also works for other sentences that don't adhere to the this is... pattern, such as la niña es bonita to ¿es bonita la niña?
3) Don't stress about do: In English, questions typically contain the verb do, yet in Spanish, the term do is implicitly part of the verb.
Hence, the transformation looks as follows:
1. ¿Prepara la prueba la Profesora Cruz?
Is Professor Cruz preparing the exam?
2. ¿Necesitamos estudiar Sandra y yo?
Do Sandra and I have to study?
3. ¿Practican los chicos el vocabulario?
Are the boys practicing the vocabulary?
4. ¿Termina Jaime la tarea?
Is Jaime finishing the homework?
5. ¿Trabajas tú en la biblioteca?
Are you working in the library?
Either A or C is acceptable as both are typical
La respuesta es metafórica, ya que estás formulando una proposición.
