Answer:
Total Amount spent on all the cards = $ 42.3
No of cards = 16 .
Step-by-step explanation:
The cost is calculated by multiplying the number of items with their costs. As we have different costs for each card we will add the costs of different cards to get the total costs.
Janet buys 3 postcards for $1.05.
Janet spends 3* $1.05= $ 3.15
Rosie buys five postcards for $1.75
Rosie spends 5 * $ 1.75= $ 8.75
Tanya buys eight postcards for $3.80
Tanya spends 8 * $3.80 = $ 30.4
Total Amount spent on all the cards = $ 3.15+$ 8.75+$ 30.4= $ 42.3
No of cards = 3 + 5+ 8= 16 cards were bought .

solve for x if z = m - x
Answer:
x=m-z
Step-by-step explanation:
The first step is to isolate x and to do this we got to subtract m from both sides which would give us -m+z=-x, the next step is to get x to be positive so we have to divide both sides by negative 1 which is because there is a 1 beside all of the values, and when we do divide both sides by negative 1 we get x=m-z
On a coordinate plane, a triangle is shown. It has points A prime (4, 2), B prime (8, negative 8), and C prime (4, negative 8).
What is the pre-image of vertex A' if the rule that created the image is ry-axis(x, y) → (–x, y)?
A(–4, 2)
A(–2, –4)
A(2, 4)
A(4, –2)
Answer:
The answer for this question would be A(-4,2) because the preimage of 4,2 would be A(-4,2).
Answer:
The answer would be option a) A(–4, 2)!

Here are two similar rectangles.
4 cm
4.8 cm
7 cm
Work out the area of the larger rectangle.
Answer:
[tex]40.32cm^{2}[/tex]
Step-by-step explanation
4*1.2=4.8
7*1.2=8.4
8.4*4.8=40.32
A rectangle is a two-dimensional shape where the length and width are different.
The length and width of the larger rectangle are 4.8 cm and 8.4 cm.
The area of the larger rectangle is 40.32 cm².
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Two similar rectangles:
Smaller rectangles:
Length = 4 cm
Width = 7 cm
Larger rectangles:
Length = 4.8 cm
We need to find the width of the larger rectangle.
Since the two rectangles are similar.
4 cm = 4.8 cm
Multiply 7/4 on both sides.
7/4 x 4cm = 7/4 x 4.8 cm
7 cm = 8.4 cm
Now,
Larger rectangle:
Length = 4.8 cm
Width = 8.4 cm
Now,
The area of the larger rectangle:
Area = Length x width
Area = 4.8 x 8.4
Area = 40.32 cm²
Thus,
The area of the larger rectangle is 40.32 cm².

Jeff bought a bottle of water for $2. He also bought some hot dogs for $3 each. Jeff did not spend more than $14 on the hot dogs and the bottle of water. Which inequality can be used to find h, the number of hot dogs that Jeff could have bought? A.3h−2≤14 B.3h+2≤14 C.3h−2≥14 D.3h+2≥14
Answer:
D. 3h + 2 ≥ 14
Step-by-step explanation:
Cost of Bottle water = $2
Cost of Hot dogs = $3
Number of hot dogs bought = h
Total cost of hot dogs = price × quantity
= 3 * h
= 3h
Jeff did not spend more than $14
Total cost of bottle water and hot dogs
3h + 2 ≥14
The correct answer is D
D. 3h + 2 ≥ 14

Brayden is making dumplings. If he uses 3 5
a cup of dough for each dumpling, how much dough does Brayden need to make 9 dumplings?
WELL, considering 3 5 is three fifths, then all you gotta do is multiply 3/5 by 9 to get your answer. Your answer, in decimals, is 5.4!
Hope this helps, if not, comment below please!!!
( ps: if you want me to convert 5.4 to fraction, just let me know! )
Answer:
27/9 or 5 2/9
Step-by-step explanation:
1. If one dumpling is worth 3/5 just multiply the 3 (numerator) by the amount of dumplings Brayden wants to make (9) so you would get the equation 3(9) and the answer is 27.
2. 27 is now the new numerator so put it over 5: 27/5. 27/5 is an improper fraction so the proper way of putting it would be 5&2/9.
3. Brayden needs 27/5 or 5&2/9 cups of dough to make 9 dumplings.
Kelly needs to travel 12 miles. Taxi A charges $3.00 plus $0.30 every 1/9 mile. Taxi B charges $3.25 plus $0.20 every 1/9 mile. How much money (in dollars) does kelly save by using taxi B instead of taxi A? (PLEASE HELP ASAP)
Answer:
$10.55
Step-by-step explanation:
Total miles traveled = 12miles
If taxi A charges $0.3 for every 1/9 mile, then for 12 Miles, he will charge;
12×0.3/(1/9)
= 12×0.3×9
= 108×0.3
= $32.4
Amount charged initially = $3.00
Total charge by Taxi A = $32.4+$3.00
Total charge by Taxi A = $35.4
If taxi B charges $0.2 for every 1/9 mile, then for 12 Miles, he will charge;
12×0.2/(1/9)
= 12×0.2×9
= 108×0.2
= $21.6
Amount charged initially = $3.25
Total charge by Taxi B = $21.6+$3.25
Total charge by Taxi B = $24.85
Total money saved by Kelly = Amount charged by Taxi A - Amount charged by Taxi B
Total money saved by Kelly = $35.4-$24.85
= $10.55
Hence Kelly saved $10.55 using taxi B
