A family of 4 is buying cell phones. Each phone costs x dollars if the family buys the super plan which costs $89 for each family member. The total cost for each family member to have a phone with the super plan is $1,952

Part A

Which equation represents this situation?

O4(2 + 89) = 1,952

O (x + 89) + 4 = 1,952

4x + 89 = 1,952

O 4x(89) = 1,952

Part B

What is the cost, in dollars, of each phone?

Each phone costs $

Step-by-step explanation:.

From the question, the equation to illustrate the above question will be:

4(x + 89) = 1952

We can then solve further to get the value of x which will be:

4x + 356 = 1952

4x = 1952 - 356

4x = 1596

x = 1596/4

x = 399

Each phone cost $399

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
