Answer:
x = 3
Step-by-step explanation:
Let's solve your equation step-by-step.
4x+3=7x−6
Step 1: Subtract 7x from both sides.
4x+3−7x=7x−6−7x
−3x+3=−6
Step 2: Subtract 3 from both sides.
−3x+3−3=−6−3
−3x=−9
Step 3: Divide both sides by -3.
-3x ÷ -3 = x
-9 ÷ -3 = 3
x = 3

4 years ago a pint of milk
cost £1.05 it now costs £1.26.
What is the percentage
increase of the cost of milk
over 4 years?
Given-
Cost of milk 4 years ago = £1.05
To find-
Percentage increase in cost
Solution-
Increase in cost = £ ( 1.26 - 1.05 )
→ £ 0.21
Percentage increase :-
[tex] \frac{0.21}{1.05} \times 100[/tex]
[tex]→ 20[/tex]
Therefore, Percentage increase of the cost of milk over 4 years is 20% .

Rate of change=1.26-1.05=£0.31
Now percentage of change
[tex]\\ \sf\longmapsto \dfrac{0.21}{1.05}\times 100[/tex]

You buy a movie ticket for $5.25 and popcorn for $2.98. You pay with a 10-dollar bill. How much change will you get back?
=======================================================
Explanation:
Use of a calculator makes quick work of this type of problem
5.25 + 2.98 = 8.23
10.00 - 8.23 = 1.77
-----------
If you want to do this using mental math, then one trick is to do this:
Think of 2.98 as 3.00, then add this to 5.25 to get 8.25. Notice that we're 2 cents too high (because of the jump from 2.98 to 3.00), so we need to subtract 2 cents from 8.25 to get 8.23
So that's a fairly quick way to add those two numbers in your head. The more practice you get, the quicker it will happen.
As for the subtraction part, you have a number of routes. Possibly a quick way is to jump from 23 cents to 30 cents (plus 7), then jump from 30 cents to 100 cents (plus 70). Therefore, we have 7+70 = 77 as the overall jump to get us to the nearest dollar. But we'll need one more extra dollar to end up at $10 exactly.
In other words, the "plus 77 cents" portion only gets us from $8.23 to $9, so that's why we need that extra dollar in change. Therefore, we've computed $1.77
I apologize for being a bit wordy. Despite being a bit long-winded, this mental math should come fairly quickly after enough practice.

John has earned scores of 87%, 95%, 92%, 89%, 84% on his unit exams. If the final exam counts 1.5 times as much as a unit exam, what score must John make on his final exam to finish the class with an average of at least 90%?
The score John must have on his final exam in order to finish the class with an average of at least 90% is 62%.
In order to determine the score the that John must have in order to make an average of at least 90%, we have to determine the total sum of the scores he already has.
Sum of scores he already has = 87% + 95% + 92% + 89% + 84% = 447
Sum of scores he must have at the end of his sixth test = Average he must have on his average at the end of his final exam x number of exams written. 90 x 6 = 540
In order to determine the score John must have subtract 447 from 540. Divide the answer by 1.5.
540 - 447 = 93%
93 / 1.5 = 62%

a air balloon is at a height of 2,520 feet. it begins to descend at the rate of 140 feet per minute.
2. Find the expression for 2,5,8,10,15 minutes
Step-by-step explanation:
just think a little bit.
the balloon goes down 140 feet per minute.
how many feet will it have descended after 2 minutes ?
twice as much, right ?
after 5 minutes ? 8 minutes ? 10 minutes ? 15 minutes ?
we have to multiply.
simply because we need to maintain the value of the ratio feet/minute at all times.
so, when we multiply the "minute" part (by saying e.g. 5 minutes), we need to multiply the "feet" part with the same factor to keep the overall ratio the same. and then the resulting "feet" part gives us the answer.
so, after 2 minutes that means
140 ft / 1 min × 2/2 = 280 ft / 2 min
=> it descended 280 ft.
so, it's height is then at that moment
2520 - 280 = 2240 ft
5 minutes
140 ft / 1 min × 5/5 = 700 ft / 5 min
=> it descended 700 ft.
so, it's height is then at that moment
2520 - 700 = 1820 ft
and so on.
we see, that the general equation to determine the actual height (h) of the balloon depending on the passed number of minutes (m) is then
h = 2520 - 140m
so
2520 - 140×2 = 2240 ft
2520 - 140×5 = 1820 ft
2520 - 140×8 = 1400 ft
2520 - 140×10 = 1120 ft
2520 - 140×15 = 420 ft

Suppose a parabola has
vertex (5, -3) and also passes through the point (6, 1). Write the equation
of the parabola in vertex form.
Oy = (x – 5)2 -3
Oy = 4(x – 5)2 -3
Oy = 4(x + 5)2 -3
Oy = 4(x – 5)2 + 3
Answer:
I think is The second one
Step-by-step explanation:
Option B is correct, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.
What is Parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point and from a fixed straight line which is known as the directrix.
We can start by using the vertex form of the equation of a parabola, which is given by:
y = a(x - h)² + k
where (h, k) is the vertex of the parabola and a determines the shape and direction of the opening of the parabola.
We are given that the vertex is (5, -3),
Substitute h = 5 and k = -3:
y = a(x - 5)² - 3
We also know that the parabola passes through the point (6, 1), so we can substitute x = 6 and y = 1:
1 = a(6 - 5)² - 3
1 = a - 3
a = 4
Substituting a = 4 into the equation
y = 4(x - 5)^2 - 3
Hence, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.
