Answer:
can i have brainliest? :) hope this helpeddd
Step-by-step explanation:
i don't know what im supposed to match it too but im just gonna solve the equation
2x + 5 = 19
isolate the variable
2x + 5 = 19
-5 -5
2x = 14

2 2
x= 7
That's an increase of 30,000,000 people in one year, a slope of 30 million and a good year for the internet.
If t is the year, and p is number of internet users,
p = 30000000(t - 1997) + 60000000
Answer: p = 30000000(t - 1997) + 60000000
As for linear versus exponential, one year of data can't really distinguish.
Twelve times 3 added to three is equal to?
Answer:
120 pounds
Step-by-step explanation:
We can use systems of equations to solve this problem. Assuming j is Jim's weight and b is Bob's weight, the equations are:
j + b = 180
b - j = 1/2b
Let's get b - j = 1/2b into standard form (b, then j, then the equal sign, then the constant.)

Now we can solve using the process of elimination.

Now we know how much Bob weighs, for fun, let's find Jim's weight by substituting into the equation.

So Bob weighs 120 pounds and Jim weight 60 pounds.

7x-3 = 18
+3 for both sides
7x = 21
devide 7 for both sides
x = 3
