Answer:
price Willy paid = $300
Step-by-step explanation:
Wally purchased a desk for 2/3 of the original price. The original price of the desk is given as $450. 2/3 of the actual price simply means 2/3 multiply by the original price.
original price = $450
To calculate 2/3 of $450.
2/3 × 450
multiply 2 by 450
= 900/3
divide 900 by 3
= $ 300
price Willy paid = $300
price Willy paid = $300
Answer:
The number of big pictures are 49 and number of small pictures are 48 .
Step-by-step explanation:
Let us assume that the number of big pictures are x .
Let us assume that the number of small pictures are y .
As given
Big pictures are 56$ each small ones are 34$.
97 were sold at the total of $4,376.
Equations becomes
x + y = 97
56x + 34y = 4376
Multiply x + y = 97 by 56 and subtracted from 56x + 34y = 4376 .
56x - 56x + 34y - 56y = 4376 - 5432
-22y = - 1056
22y = 1056
y = 48
Put value of y in the equation x + y = 97
x + 48 =97
x = 97 - 48
x = 49
Therefore the number of big pictures are 49 and number of small pictures are 48 .
The correct answer is:
12 12/15, or 12 4/5.
Explanation:
15 goes into 192 12 times. 15(12) = 180. This leaves us a remainder of 192-180 = 12. This gives us 12 12/15.
Both 12 and 15 can be divided by 3; (12÷3)/(15÷3) = 4/5.
This gives us 12 4/5.
Answer:
D.
Rosie knows that she paid a total of $30 for the yoga classes. She does not know how many classes she bought.
LISTEN all i know is that this the RIGHT one
A.x = 10
B. x = 9
C.x = 11
D.x = 8
You can find the value of x in the function f(x) = 3x - 7 when f(x) = 20 by isolating x in the equation. This process leads to an answer of x = 9.
To solve this problem, you need to substitute the given function's value f(x)=20 into the equation and solve for x.
So, you have the equation 3x-7=20. In the next step, you add 7 to both sides to isolate 3x on one side, which gives you 3x=27.
Finally, divide both sides by 3 to find the value of x. Doing so, you get x = 27/3, which simplifies to x = 9.
Therefore, when f(x) = 20, the value of x is 9, which matches answer option B.
