Answer: they are equal

To write a fraction as a percentage the easiest method is if we can change the denominator to 100.

#3/40 xx2.5/2.5 = 7.5/100 = 7.5%#

In many cases that method does not work,

so we can also do this by #xx 100%#

#3/40 xx 100%#

=#7.5%#

Answer:

-36x+55

Step-by-step explanation:

3(16−4x(3))+7

=(3)(16)+(3)(−12x)+7

=48+−36x+7

next you have to combine like terms

=48+−36x+7

=(−36x)+(48+7)

=−36x+55

Answer:

24 weeks.

Step-by-step explanation:

25x = 600

divide both sides by 25 to get:

x = 24

Answer:

24 weeks

Step-by-step explanation:

use y = mx+b

      y = total amount saved = $600

      m = amount saved per week = $25

      x = number of weeks saving = ?

      b is not needed in this problem

600 = 25X

x = 600/25

x = 24

The short answer is that algebra doesn't work that way. You wouldn't divide *everything* by 2, but every term that contains a factor of 2.

In the expression

2 (6x - 1) + 2 (2x + 5)

both terms have a factor of 2 (the 2 out in front of them). They're the ones that get canceled when dividing by 2:

(2 (6x - 1) + 2 (2x + 5)) / 2 = 2/2 (6x - 1) + 2/2 (2x - 5)

… = 1 (6x - 1) + 1 (2x - 5)

… = (6x - 1) + (2x - 5)

and so on.

Looking ahead, it turns out that the equation is solved by x = 7. This makes 6x - 1 = 41 and 2x + 5 = 19. So the equation is saying that, if you make these replacements,

2×41 + 2×19 = 120

If you divide *everything* on the left by 2, you end up with fractions:

(2/2)×(41/2) + (2/2)×(19/2) = 41/2 + 19/2

but 41 + 19 = 60, so the end result would be 30, but that's not the same as 120/2 = 60.

Answer:

x = 9

Step-by-step explanation:

x²-18x+91 = 10

x²-18x+81 = 0

(x-9)(x-9)= 0

x = 9

check:

9² - 18 (9) + 91

81-162+91 = 10

Answer:

5 goals

Step-by-step explanation:

4 goals per game for 15 games means a total of 60 goals in that season. You have 4 goals per game for 14 games meaning you have a total of 56 goals. To overtake the leading team you must score a minimum of 5 goals to become the leading scorer. (Double-check to make sure I am correct)

The expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)

We break up a number according to its place value and expand it to show the value of each digit, this process is called the expansion of the numbers.

Given that, we are asked to find the expanded form of 8.478,

The expanded form is :-

8 =  1 place = 8×1

0.4 = 1/10 place = 4×1/10

0.07 = 1/100 place = 7×1/100

0.008 = 1/1000 place = 8×1/1000

Therefore,

8.478 = 8×1+4×1/10×7×1/100+8×1/1000

Hence, the expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)

Step-by-step explanation:

The answers for the given problem can be stated as, "The inequality that represents the different sentence is represented by option (D)."And, "The inequality that represents the sentences that are alike is represented by options (A), (B) and (C) respectively."

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

The expression for inequality for all the options are written one by one as follows,

(A) k is less than or equal to -3.

=> k ≤ -3.

(B)  k is no more than -3

=> k ≤ -3

(C) . k is at most -3

=> k ≤ -3

(D) k is at least -3

=> k ≥ -3

Hence, options (A), (B) and (C) represents like while (D) represents different inequality.

Answer:

[tex]x=18[/tex]

Step-by-step explanation:

By rearranging and multiplying by 6 at the end:

[tex]\frac{1}{2}x - 7 = \frac{1}{3}(x-12)\\\frac{1}{2}-7 = \frac{1}{3}x - 4\\\frac{1}{2}x - \frac{1}{3}x = -4 + 7\\(\frac{3}{6} - \frac{2}{6})x = 3\\\frac{1}{6}x = 3\\x = 3 \cdot 6 = 18[/tex]

Answer:

I. First number, a = 40.

II. Second number, b = 50.

III. Third number, c = 120.

Step-by-step explanation:

Let the three numbers be a, b and c respectively.

Given the following data;

Translating the word problem into an algebraic equation, we have;

a + b + c = 210

b = a + 10

c = 3a

Substituting the value of b and c into the equation, we have;

a + a + 10 + 3a = 210

5a + 10 = 210

5a = 210 - 10

5a = 200

a = 200/5

a = 40

To find the value of b;

b = a + 10

b = 40 + 10

b = 50

To find c

c = 3a

c = 3*40

c = 120
