Answer:
D) division
Step-by-step explanation:
we know that a ratio is a quantitative relation between two numbers
so let's say
the ratio of boys to girls is 3:4
we know that for every 3 boys there are 4 girls
therefore it is a division operation
For bank a they have to pay 5 checks to get 20 dollars. and for bank b they have to pay 4 checks to get to 20 dollars
Answer:the company bought 12 computers and 4 printers.
Step-by-step explanation:
Let x represent the number of computers that the company bought.
Let y represent the number of printers that the company bought.
The company buys a total of 16 machines. It means that
x + y = 16
Each computer costs $550 and each printer costs $390. If the company spends $8160 for all the computers and printers that was bought, it means that
550x + 390y = 8160 - - - - - - - - - - 1
Substituting x = 16 - y into equation 1, it becomes
550(16 - y) + 390y = 8160
8800 - 550y + 390y = 8160
- 550y + 390y = 8160 - 8800
- 160y = - 640
y = - 640/ - 160
y = 4
Substituting y = 4 into x = 16 - y, it becomes
x = 16 - 4
x = 12

The value of x such that the vertices 3x + 10 and x + 60 are equal is 25
<h3>What are vertices?</h3>
Vertices are the endpoints or corners of a shape (such as triangle, square, rectangle and related shapes)
<h3>How to determine the value of x?</h3>
The two vertices are given as:
3x + 10 and x + 60
The condition on the two vertices are not given.
So, we assume that the vertices are equal (as in the base angles of an isosceles triangle)
So, we have the following equation
3x + 10 = x + 60
Subtract x from both sides of the equation
2x + 10 = 60
Subtract 10 from both sides of the equation
2x = 50
Divide both sides of the equation by 2
x = 50/2
Evaluate the quotient
x = 25
Hence, the value of x such that the vertices 3x + 10 and x + 60 are equal is 25
