3x+45=180

3x=180-45

3x=135

x=45  

Step-by-step explanation:

use the equation:
180=2x+45+x
180=3x+45 (combine like terms)

Answers

Answer:

6

Step-by-step explanation:

first let's find all the possible combinations excluding 6+6 to get 12 using addition, we exclude 6+6 because we can't have the same integer for different variables. these are 0+12, 1+11, 2+10, 3+9, 4+8, and 5+7(also the other way around but i start with these). using common sense, I started higher because there is no way d = 0 and e= 12, so i went from 5+7 down. through trial and error and some luck, 5+7 was the correct combination. let's insert the numbers with their variables. d = 5 and e = 7. now we figure out, what minus 5 is 7? if you learned fact families in kindergarten, you'd know to find this out you add 5+7, which is 12. now we divide 12 by 2, because it's the same number added together to get this number, so you now get 6+6. does the equation make sense? (6+6) - 5 = 7, that checks out, and 5+7=12.

The populations of two different cities are modeled by the equations shown below. The population (in thousands) is represented by y and the number of years since 1970 is represented by x. What year(s) did the cities have the same population? What was the population of both cities during the year(s) of equal population? Answers: (year 1995, 425000 people) and (year 2022, 1910000 people)

Baskinville: y = x2 – 22x + 350

Cryersport: y = 55x – 95
I NEED THE EXPLANATION OF HOW TO GET TO THE ANSWER PLEASE

Answers

Answer: hope this helps love.

Step-by-step explanation:

years of equal population are 1995 and 2022.

in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.

Step-by-step explanation: Baskinville: y = x2 - 22x + 350

Cryersport: y = 55x - 950

Note that x2 is xsquare not x2

Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.

2 1/4 ⋅ 1 2/3
as a mixed number

Answers

Answer:

[tex]3\frac{3}{4}[/tex]

Step-by-step explanation:

We have two mixed numbers and are asked to multiply them together.

2 1/4 * 1 2/3

First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.

Multiply the whole number by the denominator and add the numerator.

2 1/4 * 1 2/3

9/4 * 5/3

Now multiply across,

[tex]\frac{9*5}{4*3}[/tex]

[tex]\frac{45}{12}[/tex]

Now we need to convert this back into a mixed number.

So how many times does 45 go into 12?

3 times, and 3 are left.

[tex]3\frac{3}{4}[/tex]

Simplify given fraction into mixed fraction is 3³/₄

Give that:

[tex]2\frac{1}{4} \times 1\frac{2}{3}[/tex]

Find:
