Answer:
I believe the answer would be 2,400 minutes over four weeks of practice.
Step-by-step explanation:
2.5x4=10
that is 10 minutes a week. you need to find four weeks so you would multiply more.
10x4=40
there is 60 minutes in an hour so you need to multiply more.
40x60=2,400
so that is your answer, 2,400 minutes.
Answer:
10: 12, 5: 6, 5/6, 10/12
Step-by-step explanation:
Answer:
To convert ml to L you would divide your number by 1000, because 1L=1000ml
3,450/1000= 3.45
3,450ml = 3.45L

Your answer is in the screenshot! :)
Step-by-step explanation:
1. Solve for yy in y+7x=50y+7x=50. y=50-7x
y=50−7x
2. Substitute y=50-7xy=50−7x into 14x-5y=-2814x−5y=−28. 49x-250=-28
49x−250=−28
3. Solve for xx in 49x-250=-2849x−250=−28. x=\frac{222}{49}
x= 49 222
4. Substitute x=\frac{222}{49}x= 49 222 into y=50-7xy=50−7x.
y=\frac{128}{7} y= 7 128
5. Therefore, \begin{aligned}&x=\frac{222}{49}\\&y=\frac{128}{7}\end{aligned} x= 49 222 y= 7 128 Hope this helped!! :))
X^2 + 2x < 8
x^2 + 2x - 8 < 0
(x + 4)(x - 2) < 0 ,,
{x + 4 < 0 and x - 2 > 0} or {x + 4 > 0 ,,and x - 2 < 0} ,,
{x < -4 and x > 2} or {x > -4 and x < 2},,
Discard x < -4 and x > 2 because it has no solutions, leaving just
x > -4 and x < 2 ,,
-4 < x < 2
