Answer:
8 weeks
Step-by-step explanation:
Given data
Matteo
Amount= $400
Spending per week= $10
Hence his balance after x weeks is given as
y=400-10x-------------1
Luca
Amount= $200
Spending per week= $15
Hence his balance after x weeks is given as
y=200+15x-------------2
Equate 1 and 2
400-10x=200+15x
collect like terms
400-200=15x+10x
200=25x
x= 200/25
x= 8 weeks
Hence it will take 8 weeks
Answer:
5.6
Step-by-step explanation:
you multiply the base and height then divide by 2
Y= -x+4
2x+2(-x+4)=8
2x-2x+8=8
8=8
x+y= 4
2x+2y= 8
-2x-2y= -8
2x+2y= 8
0=0
the answer is b inconsistent
The magnitude of WX is 
⇒ c
Step-by-step explanation:
The magnitude of XY (its length) where,
is IXYI = 
∵ W = (-2 , 8 , -3)
∵ X = (1 , 4 , -1)
- To find the magnitude of WX use the formula above
∴ 
= -2 and 
= 1
∴ 
= 8 and 
= 4
∴ 
= -3 and ![z_{2]](https://tex.z-dn.net/?f=z_%7B2%5D)
= -1
- Substitute these values in the rule above
∵ IWXI = 
∴ IWXI =
The magnitude of WX is

A. If she completed 1/4, 3/4 are still left to be done over 5 days.
To find out how much per day, divide 3/4 by 5 (multiply the first number by the reciprocal of the second).
3/4*1/5= 3/20.
Final answer: 3/20
b. If she irons 3/20 a day, she should iron 6/20 or 3/10 over the course of two days, Thursday and Friday. 3/10 of 40 is 40*0.3= 12
Final answer: 12 shirts
