$2.50 each. She purchased 14 items and spent $43. Which system of equations could be used to
determine how many of each item Alicia purchased?
(1) 3.50H + 2.50P = 43 (3) 3.50H + 2.50P = 14
H+P = 14
H+ P = 43
(2) 3.50P+2.50H = 43
P+ H = 14
(4) 3.50P + 2.50H = 14
P+H = 43

Andy’s dog weighs 27 pounds, which is 3/4 the weight of Seher’s dog. How many pounds does Seher’s dog weigh?
Answer:
20.25 lbs
Step-by-step explanation:
Multiply 27 by 3/4 or .75 to equal 20.25.
Answer:
36 pounds.
Step-by-step explanation:
Suppose Seher's dog weigh x pounds, here is an equation:
27=[tex]\frac{3}{4}[/tex]x
multiply 4 on both sides and dividing 3 on both sides, we get:
36=x
we flip this around:
x=36
So, Seher's dog weighs 36 pounds.

Which model shows ^3√64 = 4 ?
Answer:
if we carefully observe, left-bottom model contains 4 units on each side of the cube.
Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].
The correct model is attached below.
Step-by-step explanation:
Given the expression
[tex]\sqrt[3]{64}=4[/tex]
Cubing both sides
64 = 4³
Thus, the cube will have 4 units on each side.
Now, if we carefully observe, left-bottom model contains 4 units on each side of the cube.
Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].
The correct model is attached below.
A rectangular garden is 45 ft wide and 70 ft long. In a drawing, the width is 9 in. Identify the length on the drawing.
Answer: the length in the drawing is 1.166666...ft or 14 inches.
Step-by-step explanation:
there are 0.75 ft in 9 inches, and 45/0.75=60. So, to find x you need to divide 70 by 60. :))
If you needed to answer in inches, I found my answer by dividing 45/9 which equals 5, so x=70/5. x=14 inches.

Help. Please open powerpoint and help me!
Answer:
30.4%
1000 at £1.10
1000 x 1.10 = £1100
35% of 1000 is given away
1000 - 35% = 1000 - 350 = 650 left
35% of £1100 = £385, subtract to get £715 pounds worth of pins left
650 are left, with 385 pounds lost
60% of 650 = 390 pins sold at £3 each
40% of 650 = 260 sold at £5 for 2
3 x 390 = £1170 made from the first lot
260/2 = 130 x 5 = £650 made from the second lot
£1170 + £650 = £1820 from sales
Sales - cost to make - losses (giveaways) = profit value
1820 - 1100 - 385 = 335 pounds of profit
To find the gross profit margin, we take the profit, and find what percentage of the production cost it is.
335 is about 30.45% of 1100
30.45%, which is 30.4% to 1 decimal place.

Answer:
20 is the total perimeter
Step-by-step explanation:
Answer:
6x + 2
Step-by-step explanation:
The area of a square is side length times itself.
In this problem, the area of one square is:
x², or x * x. So the side length of each square must be x.
In the rectangular shape, the area would be top * side. The side is equal to x because "side" is equal to the sides of the other squares (because a square's sides are all the same).
Plugging that into the equation, top * x = x, so the top must be 1.
There are 5 "full-length sides" on the two "full" squares on the left. Then, in the last skinny rectangle, there are two "tops", and one "full-length side".
Substitue the values of each side.
5x + 1 + 1 + x = 6x + 2
