Answer:
6 $10 bills
Step-by-step explanation:
First you have to make a system of equations like such
5x + 10y = 150
x + y = 24
Now you can use any strategy to simplify it but I'll use multiplication and the subtraction:
5x + 10y = 150 - 5x + 5y = 120 = 5y = 30 this simplified is y = 6. You then substitute 6 for y in either equation. x + 6 = 24 and make it on opposite sides. x = 18.
So 18 $5 bills and 6 $10 bills
Answer:
The number is 70
Step-by-step explanation:
Is means equals and of means multiply
91 = 130% *W
Changing to a decimal form
91 = 1.3W
Divide each side by 1.3
91/1.3 = 1.3 W/1.3
70 = W
Answer:
5 cm and 13 cm
Step-by-step explanation:
Let b be the width of the rectangle.
Length = 3+2b
The area of the rectangle is 65 cm²
We need to find the dimensions of the rectangle. The area of a rectangle is given by :
A = lb

Neglecting the negative value, the width of the rectangle is 5 cm.
Length = 3+2b
=3+2(5)
=3+10
=13 cm
Hence, the dimensions of the rectangle are 5 cm and 13 cm.

Step-by-step explanation:
The volume of a Cone =

Since for the ice cream cone has h = 4 inches; r = 0.75; π = 3.14
Then Volume of the Cone = 2.355 in³
∴ This ice cream cone can hold ≈
2.36 in³ of ice cream without overflowing
