Aubree practices the piano 1197 minutes in 3 weeks. At what rate did she practice, in minutes per day?

Norma-Jean [14]

Answer:

57

Step-by-step explanation:

We need to create a ratio. so Aubree practices the piano for 1197 min: in 3 weeks. So for 1 week, we have to divide 1197 by 3, so 1197/=399. And so we know that 1 week is 7 days, just divide 399 by 7! 399/7=57. The rate that she practiced per day is 57 minutes. So one last final step just to check if this answer is correct is to divide 57 by 60, and that is 0.95. 0.95 out of 1.00 minutes per day is 95/100. Cross multiply with x/60, and you will get your answer, which is 57.

The sum of 5 consecutive even numbers is 250. What is the fourth number in this sequence?

Sophie [7]

Answer:

Our fourth number is 52.

Step-by-step explanation:

Let our first even number be <em>x</em>.

Then the second even number must be (<em>x</em> + 2), the third (<em>x</em> + 4), fourth (<em>x</em> + 6), and the fifth (<em>x </em>+ 8).

They sum to 250. Hence:

$x+(x+2)+(x+4)+(x+6)+(x+8)=250$

Solve for <em>x</em>. Combine like terms:

$5x+20=250$

Subtract 20 from both sides:

$5x=230$

And divide both sides by five. Hence:

$x=46$

Thus, our sequence is 46, 48, 50, 52, and 54.

Hence, our fourth number is 52.

olya-2409 [2.1K]

Answer:

3, 8, 14, 30, 58

Step-by-step explanation:

As with all formulas, put the numbers in place of the corresponding variables, and do the arithmetic.

$a_1=3\qquad\text{given}\\\\a_2=8\qquad\text{given}\\\\a_3=2a_1+a_2=2(3)+8=14\\\\a_4=2a_2+a_3=2(8)+14=30\\\\a_5=2a_3+a_4=2(14)+30=58$

The first 5 terms of the sequence are 3, 8, 14, 30, 58.
