♡ The Explanation/Step-By-Step ♡
4x - 2 (x + 1) = 3x + 10
2x - 2 = 3x + 10
2x - 2 + 2 = 3x + 10 + 2
2x - 3x = 3x + 12 - 3x
-x = 12
-x/-1 = 12/-1
x = -12

Peter, Bridget and Caroline share some sweets in the ratio 6:3:2. Peter gets 56 more sweets than Caroline. How many sweets are there altogether?
Answer:
The scale in the ratio given considers the case that there are 9 sweets (2 + 3 + 4), however, to answer our question, we need to scale up the ratio, so that we can work out the share when we have 36 sweets
Step-by-step explanation:
Ratios are a way of displaying the proportional split of a value and they are very similar to fractions. In the example above, we see that for every 2 sweets Amy has, Beth gets 3 and, Colin will get 4. Like fractions, this proportion will stay the same regardless of the scale of the ratio. The scale in the ratio given considers the case that there are 9 sweets (2 + 3 + 4), however, to answer our question, we need to scale up the ratio, so that we can work out the share when we have 36 sweets. So, what scale factor do we need to get it from a total of 9 sweets to a sum of 36 sweets? We know that 9 multiplied by 4 gives us 36, therefore, we can use a scale factor of 4. Remember how whatever is done to the denominator of a fraction has to be done to the numerator? Ratios like to behave the same way, so now that we have scaled up the sum of the ratio, we need to scale up the individual values by 4 – (2x4) : 3x4 : 4x4. Once we work it out we get the new ratio 8:12:16. You can check if you’re right by adding up the new values and you will see that 8 + 12 + 16 = 36, which is the value that the 9 was initially scaled up to. So we now know that when sharing the 36 sweets, Amy will get 8 sweets, Beth will get 12 sweets and Colin will get 16.

Describe what a finite graph is and give an example of how a finite graph would be used to represent something.
Answer:
A graph with a set amount of numbers.
Step-by-step explanation:
Infinite means never ending and that's what most graphs are. But, a finite graph is a graph that doesn't have arrows at the end of the lines. (simplified answer) A better way of saying it is a graph with a fixed starting position and a fixed ending position. You can use this type of graph if you don't want to go over or under a certain value.

the function 8x^2-9x-148x 2 −9x−14 divided by x-2x−2
Answer:
8x + 7Step-by-step explanation:
8x² - 9x - 14 divided by x - 2
(8x² - 9x - 14)/(x - 2)(8x² - 16x + 7x - 14)/(x - 2)=(8x(x - 2) + 7(x - 2))/(x - 2) =8x(x - 2)/(x - 2) + 7(x - 2)/(x - 2) =8x + 7Glen buys four tickets for a concert. Each ticket costs £54 Glen also has to pay a booking fee.
The booking fee is 5% of the total price of the tickets.
Work out the total amount Glen has to pay.Povinná odpověď. Jednořádkový text.
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Maths.
Cost of each ticket = £54
Glen purchased tickets= 4
total cost of tickets alone = 54*4 =£216
now calculation of the 5% tax of the tickets,
5/100 * 216 = £ 10.8
hence the total amount Glen has to pay is
=> 216+10.8 = £226.8
Answer:
51.30
Step-by-step explanation:
5% of 54$ is 51.30
1/4x - 5 = 6
How do I get the answer to this question?
Answer:
x = 44
Step-by-step explanation:
6 + 5 = 11
1/4x = 11
11 ÷ 1/4 = 44
if it does not make sense, then here is the equation.
1/4(44) - 5 = 6

Cole has already taken 7 quizzes during past quarters, and he expects to have 1 quiz during each week of this quarter. Write an equation that shows the relationship between the number of weeks x and the total number of quizzes y.
Answer:
y = x + 7
Step-by-step explanation:
x = number of weeks
y = the total number of quizzes y.
Cole has already taken 7 quizzes = + 7
he expects to have 1 quiz during each week of this quarter = 1x
y = 1x + 7
y = x + 7
if 180-46 180-134 = 46 but the answer isnt 46, so i know im doing something wrong but i don’t remember how to solve these.
Answer:

Step-by-step explanation:
Because the triangle is an isosceles triangle so the math would be (180-46)/2=67
After a hike, a group of s students equally share 5 boxes of granola bars. Each box has 8 granola bars. Which algebraic expression represents how many granola bars each student has?
Answer:
40/s
Step-by-step explanation:
Number of granola boxes = 5
Number of granola per box = 8
Total granolas = 8 * 5 = 40 granola bars
Number of students = s
If each students takes equal share : Number if granola bars taken by each :
Total number of granola bars / number of students
= 40 ÷ s
40/s

Race cars each weighing ¼ pound are on a scale. The scale shows 1 ½ pounds. How many race cars are on the scale?
Answer:
6 race cars
Step-by-step explanation:
In this scenario, there would be a total of 6 race cars on the scale. Since each racecar weighs 1/4 pound then 4 racecars would equal 1. This leaves us with 1/2 or 0.5 pounds left. This would be 2 race cars since 2/4 is equal to 0.5 pounds. Therefore, if we add these two amounts up it would be a total of 6 racecars (4+2) which would total 1 1/2 pounds.

some body help answer the question in the picture below
Answer:
a) t ≥ 5
b) (see below)
Step-by-step explanation:
First, make note of the info you are given and what you're trying to do:
- at midnight, 5°C
- drops consistently 2°C per hour
- finding t
- t = # of hours past midnight when temp. was past -4°C
- put t on a number line
So, first, you need to find the first point at when the temperature goes past -4°C. Notice that the question is asking for past -4°C, not -4°C and past. This means we're not including -4°C.
Every hour, we're dropping by 2°C. You can draw a visual to better understand the situation. See the image below.
So we know that starting from 5 am, we are lower than -4°C.
This is 5 hours from midnight.
So t ≥ 5. This means that the number of hours past midnight when the temperature was colder than -4°C was 5 or more hours.
On the number line, draw a circle on 5 (between 4 and 6), but shade it in because it includes 5. Then, shade or highlight to the right of that circle to the end of the number line.
This shows that t is equal to or greater than 5.
rick believes the two expressions 4(3a-3) +2a and 14a-3 are equivalent. is he correct? explain why or why not?
Answer:
no
Step-by-step explanation:
4(3a-3)+2a when you expand youget
((4x3a)-(4x3)) + 2a = 12a - 12 + 2a then we collect the like term first 12a + 2a - 12
14a -12
therefore 14a - 12 is not equal to 14a- 3
