Answer:
4 free wedges of cheese
Step-by-step explanation:
From the above question:
3 sticks of butter purchased = 1 free wedge of cheese
12 sticks of butter purchased = x
Cross Multiply
3 × x = 12 × 1
x = 12/3
x = 4 free wedges of cheese
Therefore, when Baby Jr. Buys 12 sticks of butter, she will receive 4 free wedges of cheese.
Answer:
1) 180 degrees; straight angle
2) (5x-18)+(4x+45)=108
3) x=17
4) 90 degrees; right angle
5) (3x+6)+(5x+4)=90
6)x=10
Step-by-step explanation:
What we know:
Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 7 liters of natural oil for every 5 liters of synthetic oil.
What we need to find:
If 355 liters of synthetic oil are used, how many liters of petrolyn oil will be made?
Set up a proportion to find how much natural oil is used.
7L natural oil/5L synthetic oil = x/355 synthetic oil where x=natural oil
7/5=x/355
(5)(x)=(7)(355) cross multiplied
5x=2485 simplified
5/5x=2485/5 multiplicative inverse
x=497L
Now, add both synthetic oil and natural oil to find amount of petrolyn oil.
355 L synthetic oil + 497 L natural oil= 852 L of petrolyn oil
2/15 since there are two cards out of 15

Answer:
£592 for 16 boxes
Step-by-step explanation:
The classroom floor area is ...
A = LW = (8.8 m)(2.2 m) = 19.36 m²
The cupboard floor area is ...
A = (2.3 m)(2.1 m) = 4.83 m²
Then the total area to be covered is ...
19.36 m² +4.83 m² = 24.19 m²
At 1.6 m² per box, the number of boxes required is ...
(24.19 m²)/(1.6 m²/box) = 15.12 boxes
If we assume we can only purchase whole boxes, we need to purchase 16 boxes to cover the floor. The cost will be ...
(16 boxes)(£37/box) = £592 . . . . cost of laminate to replace the floor
