Answer:

29 pounds of type A coffee was used

Step-by-step explanation:

David's shop makes a blend that is a mixture of 2 coffee

Type A costs $4.10

Type B costs $5.25

Let a represent the number of pounds of type A coffee used

Since this month's blend used twice as many pound of type B coffee as type A

a + 2a

The total cost is $423.40

Therefore the amount of pounds of type A coffee used can be calculated as follows

4.10a + 5.25(2a)= 423.40

4.10a + 10.5a= 423.40

14.6a= 423.40

a= 423.40/14.6

a= 29

Hence 29 pounds of type A coffee was used

Combine the like terms to create an equivalent expression: <br> 2s+(−4s)=?
Sergeeva-Olga [200]

Answer:

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.

Step-by-step explanation:

Considering the expression

2s+\left(-4s\right)

As we know that

  • Like terms are said to be the terms which hold the same variables raised to the same power.
  • For example, 3x and 2x are like terms as they contain the same variable x raised to the same power.

Lets solve the expression

2s+\left(-4s\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a

2s-4s

\mathrm{Add\:similar\:terms:}\:2s-4s=-2s

-2s

Therefore,

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.
