Answer:
The statement is true.
Step-by-step explanation:
Let us assume that x is the required number.
Now, given that the number minus 3 is at most 12.
Hence, x - 3 ≤ 12
⇒ x ≤ 15 ......... (1)
And also given that 1 more than 2 times the number is at least 25.
Hence, 2x + 1 ≥ 25
⇒ 2x ≥ 24
⇒ x ≥ 12 .......... (2)
Therefore, from equations (1) and (2) we get the number must be greater than or equal to 12 or less than or equal to 15.
So, the statement is true. (Answer)
If 7 people paid $3 per ride and road 5 times, it would be $21 dollars. You could do it 3×5=15+7=21
3*-2=-6
-6*-2=12
The sequence is a number being multiplied by -2 over and over.
48, -96, 192, -384, 768, etc.
Answer:
36 personas
Step-by-step explanation:
las 2/5 partes q completaron secundaria tambien finalizaron primaria
con lo cual el tercio que estudio primaria esta dentro del grupo de personas que estudiaron
60*2/5 = 24
24 personas estudiaron
60-24=36
A quadratic equation has the general form
of: <span>
y=ax² + bx + c
It can be converted to the vertex form in order
to determine the vertex of the parabola. It has the standard form of:
y = a(x+h)² - k
This can be done by completing a square. The steps are as follows:
</span><span>y = 3x2 + 9x – 18
</span>y = 3(x2 <span>+ 3x) – 18
</span>y + 27/4= 3(x2 <span>+ 3x+ 9/4) – 18
</span>y = 3(x2 + 3/2)^2 – 99<span>/4
</span>
Therefore, the first step is to group terms with the variable x and factoring out the coefficient of x^2.
