A,D,E,F
Step-by-step explanation:
Answer:
y=-5
x=-2
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
The equation would be 2 (3+3). You would distribute the 2 to both threes and get 6+6. Then you would add them to get 12.
Answer:the price for one shirt is $7.5
the price for one pair of pants is $18.5
Step-by-step explanation:
Let x represent the price for one shirt.
Let y represent the price for one pair of pants.
Lisa goes to the mall one day and buys four shirts and three pairs of pants for $85.50. This means that
4x + 3y = 85.5 - - - - - - - - - -1
She returns the next day and buys three shirts and five pairs of pants for $115.00. This means that
3x + 5y = 115 - - - - - - - - - - - 2
Multiplying equation 1 by b3 and equation 2 by 4, it becomes
12x + 9y = 256.5
12x + 20y = 460
Subtracting, it becomes
- 11y = - 203.5
y = - 203.5/ -11 = 18.5
Substituting y = 18.5 into equation 1, it becomes
4x + 3×18.5 = 85.5
4x + 55.5 = 85.5
4x = 85.5 - 55.5 = 30
x = 30/4 = 7.5
1/3 ÷ 2 =
1/3 x 2/1. you do this by doing the reciprocal of 2, and then you do KCF ( keep, change, flip,)
keep 1/3 change ÷ to × and flip 2/1 to 1/2.
1/3 x 1/2 = 1/6.
hopefully this helps you
