I’m stuck on this problem<br> Pls help ASAP
Viktor [21]

Answer:

x=+12

Step-by-step explanation:

4(x+6)=6x=16


We move all terms to the left:


4(x+6)-(6x)=0


We add all the numbers together, and all the variables


-6x+4(x+6)=0


We multiply parentheses


-6x+4x+24=0


We add all the numbers together, and all the variables


-2x+24=0


We move all terms containing x to the left, all other terms to the right


-2x=-24


x=-24/-2

Ratioz rate unit rate <br>I have a quiz tmr 7th grade I need to learn ratio, rate unit rates!!! ​
posledela

Alright! I'll help you. Let me tell you what's ratio, rate unit rates all about! :D

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

What is the difference between a unit rate and a ratio?

Guide the discussion so that students understand that a ratio is simply the quotient of two numbers, while a rate is the ratio of two measurements that have different units (like miles and hours, or dollars and ounces). Reinforce the fact that a rate is usually expressed in per unit form, where the denominator is 1.

What are some examples of ratios?

In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

Is a rate always a ratio?

Rates and ratios. ... A rate is a little bit different than the ratio, it is a special ratio. It is a comparison of measurements that have different units, like cents and grams. A unit rate is a rate with a denominator of 1.

How do I find the unit rate?

To get the unit to equal 1, divide both numbers by the denominator; your answer is the number you get by dividing the numerator by the denominator. Use this method to calculate unit cost, too—you're calculating how much 1 item is worth, after you're given the amount that multiple items cost.

Here are some questions and how to answer them to help you! I hope this helps you! c:

Last year, Deshaun had $20,000 to invest. He invested some of it in an account that paid 9% simple interest per year, and he inv
dezoksy [38]

Answer:

the amount Deshaun invested in an account that paid 9% interest = $9,000

the amount Deshaun invested in an account that paid 5% interest = $11,000

Step-by-step explanation:

Let x = the amount Deshaun invested in an account that paid 9% interest

Let y = the amount Deshaun invested in an account that paid 5% interest.

Thus;

x + y = 20,000 - - - - (eq 1)

Now, After one year, he received a total of $1440 in interest. Thus;

0.09x + 0.05y = 1440

Multiply each term by 100 to give;

9x + 5y = 144000 ---- (eq 2)

Making x the subject in equation 1,we have;

x = 20,000 - y

Putting 20,000 - y for x in eq 2,we have;

9(20,000 - y) + 5y = 1440

180000 - 9y + 5y = 144000

180000 - 4y = 144000

180000 - 144000 = 4y

36000 = 4y

Divide both sides by 4 to give;

y = 36000/4

y = $9,000

x = 20,000 - 9000

x = $11,000
