Answer:
I am about 95% sure that this is what they want. P.s (sorry I cant put the divide symbol)
<u><em>The variable is the number of shirts she bought or x</em></u>
and the equation is <u><em>(375+50) divided by (15+2) = x</em></u>
in the solve spot put
<em><u>(375+50) divided by (15+2)=x</u></em>
<em><u>425 divided by 17=x</u></em>
<em><u>x=25</u></em>
Then your answer would be <u><em>25</em></u>
Step-by-step explanation:
first add 50 to 375 so you get the full price which will give you 425. then to find out how many shirts she bought you must add 2 to 15 to get 17. then divide 425 by 17 which is 25. so she bought <em><u>25 shirts</u></em>.
the number is how many years
C ; x must be greater than or equal to 52 because you have to be 52 inches or greater to ride this ride.
Answer:
a) 1.
Step-by-step explanation:
Supongamos que el primer número entero positivo es a tal que a ∈ Z⁺.
Luego, el conjunto de los cinco enteros positivos se puede expresar como
A = {a; a+1; a+2; a+3; a+4}
Dada la condición del problema, se debe cumplir que
a + (a+1) + (a+2) = (a+3) + (a+4)
⇒ 3a + 3 = 2a + 7
Resolviendo la ecuación resulta
a = 4
Luego, el conjunto A nos resulta
A = {4; 5; 6; 7; 8}
Puede concluirse que sólo un conjunto cumple con esta condición.
