I hope you love your mama too. It’s tough out in these streets for us mamas. Hug her neck and tell her you appreciate her. Trust me.
Step-by-step explanation:
for 1 min=9 wraps
for x(unknown minutes)=360 wraps
so I crossed multiply:
9x=360
x=360/9
x=40
so it takes 40 minutes to make 360 wraps
Answer:
It goes like this
Step-by-step explanation:
U can see the sequence
The number of sixty-minute cassette tapes ordered is 288 and the number of CDs ordered is 163.
<h3>What are the linear equations that represent this question?</h3>
1.49a + 4.98b = $1240.86 equation 1
a + b = 451 equation 2
Where:
- a = number of sixty-minute cassette tapes ordered
- b = number of CDs ordered
<h3>How many
CDs were ordered?</h3>
Multiply equation 2 by 1,49
1.49a + 1.49b = 671.99 equation 3
Subtract equation 3 from equation 1
568.87 = 3.49b
Divide both sides of the equation by 3.49
568.87 / 3.49
b = 163
<h3>How many s
ixty-minute cassette tapes were ordered ?</h3>
Subract 163 deom 451
451- 163 = 288
