Answer:
6 no 3 yes
Step-by-step explanation:
for 6 hours no because she already used 200 and now she only has 100 to spend
for 3 hours yes because that fee would be UNDER her budget
-4x-2y=-12
4x+8y=-24
--------------------------add
6y = -36
y = -6
Substitute y = -6 into -4x-2y=-12
-4x-2(-6) = -12
-4x + 12 = -12
-4x = -24
x = 6
Answer
x = 6 and y = -6
Answer:
-7
Step-by-step explanation:
Answer:
AW=10
Step-by-step explanation:
In a parallelogram opposite sides are congruent meaning XA and AZ are congruent. YA and AW are congruent. So...
Solving for XA and AZ
XA=AZ
3m=5m-4
-2m=-4
m=2
If YW=10m then 10 x 2 = 20
20 divided by 2 = 10
Answer:
14 Striped and 10 Flowered
Step-by-step explanation:
This can best be determined using a set of linear equations that are solved simultaneously.
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations. It may be solved by substitution in that one of the variable is made the subject of the equation and the result is substituted into the second equation
Given that the green and blue striped shirt is $15 and the white with purple flowers is $13. She needs to order 24 shirts and has a total of $340 to spend, let the number of striped shirts be g and that of flowered be h then,
g + h = 24 and
15g + 13h = 340
g = 24 - h
15(24 - h) + 13h = 340
360 - 15h + 13h = 340
2h = 20
h = 10
g = 24 - h
g = 24 - 10
= 14
