Answer:
Divide 250 by 9.4 to get 26.6
Step-by-step explanation:
To calculate her unit rate, 1 minute, we must divide the distance travelled over 9.4 minutes by 9.4 to see how far she travelled in 1 minute.
Answer:
2xy(x+5)(4x−1)
Step-by-step explanation:
1 Find the Greatest Common Factor (GCF).
GCF = 2xy
2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2xy (8x^3y + 38x^2y/2xy + −10xy/2xy)
3 Simplify each term in parentheses.
2xy(4x^2 +19x−5)
4 Split the second term in 4x^2+19x-5 into two terms.
2xy(4x^2 +20x−x−5)
5 Factor out common terms in the first two terms, then in the last two terms.
2xy(4x(x+5)−(x+5))
6 Factor out the common term x+5.
2xy(x+5)(4x−1)
Answer: 296 or 592
Step-by-step explanation:
Answer:
Buy the batteries and stereo online:
4.99*2= $9.98 +$90 = $99.98
6.99-5.00 = $1.99
99.98+1.99=$101.97
3Cds in store
7.97*3= $23.85
5% tax = 1.19
10% off = 2.39
$23.85 - $1.19= $22.66
22.66 + 101.97= $124.63
All in store:
12+100+23.85= 135.85 - 6.45 = $129.40
All online:
9.98 + 90 + 26.85= 126.85 +$1.99 = 128.84

The rate of each train of the northbound train traveled 10 miles per hour faster than the southbound train 26 miles per hour.
<h3>what is speed?</h3>
Speed is the time rate at which an object is moving along a path
Let the speed of southbound train is x miles/hour
so, northbound train has speed of x+10 miles/hour.
then, Speed of both train = Total distance/ total time
(x+10+x)=210/5
2x+10= 210/5
2x+10= 42
2x= 32
x= 16 miles per hour (southbound train)
northbound train: 16+10=26 miles per hour
