Please help me im very depressed and im struggling a lot on my math and i really need some answers


Which sequence shows the numbers in order from least to greatest?

Answer:

Step-by-step explanation:

Given the amount to keep one adult in a day to be x

Since 7 days = 1 week

Amount it will take to keep one adult for a week will be 7x

one adult = 7x pounds

To get the expression that show how much it costs per week to keep the 8 adults, we will say;

8 adults = y pounds

where y is the required amount

Solving both expressions

one adult = 7x pounds

8 adults = y pounds

Cross multiply

1 * y = 7x * 8

y = 56x

Hence the required expression is y = 56x

we will say that his original salary is x

x+10x/100=154000

we bring to the same denominator

(100x+10x)/100=154000

we multiply with 100

110x=15400000

we divide by 110

x=140.000

Step-by-step explanation:

15+20x=18+20x

20x+15=18+20x

20x+15=18+20x

20x+15=20x+18

20x+15=20x+18

20x+15-15=20x+18-15

1.subtract the numbers

20x=20x+3

20x=20x+3

20x-20x=20x+3-20x

1.combine like terms

Answer:

2.5%

Step-by-step explanation:

A simple interest of Ghc 37,500.00 is earned on an amount of Ghc 500,000.00 for three years. Find the rate of interest per annum?

The formula for Rate of Interest in a simple interest is given as:

r = (1/t)(A/P - 1)

Where

t = time in years = 3 years

P = Principal = Initial amount invested = Ghc 500,000.00

A = Amount after t years =

Principal + Simple Interest

= Ghc 500,000.00 + Ghc 37,500.00

= Ghc 537,500.00

Hence:

The rate of interest = (1/3) × (Ghc 537,500.00/Ghc 500,000.00 - 1)

= r = 0.025

Converting r decimal to R a percentage

R = 0.025 × 100 = 2.5%/year

Therefore, the rate of interest per annum is 2.5%

Step-by-step explanation:

i learnt in class that the number with the letter is used to divide what it equalls

Answer:

C

Step-by-step explanation:

Step 2 is correct, that is

8x = 10 ( divide both sides by 8 ), error made here by dividing by 10

x = [tex]\frac{10}{8}[/tex]

x = [tex]\frac{5}{4}[/tex]

The error was made at step 3

Answer:

B. 20%

Step-by-step explanation:

Percentage Error = (Actual Value - Expected Value) / Expected Value * 100

Actual Value = 30

Expected Value = 25

Percentage Error = (30 - 25) / 25 * 100

Percentage Error = (5) / 25 * 100

Percentage Error = 0.2 * 100

Percentage Error = 20

Answer:

3. 72= (x)+(x+1)+(x+2) where x= the smallest number

72=3x+3

5. all erasers were the same cost

25= 4x+5 (x= cost of erasers)

-5         -5

20=4x

/4   /4

x=5

each cost  $5

6. b= boxes

22= b/2 +7

15=b/2

multiply both sides by 2 to cancel the denominator

30=b

30 boxes originally

7. 40= total

8= left

2= balls given to each

x=number of friends

40= 2x+8

-8         -8

32=2x

/2   /2

x=16

she has 16 friends

8.  12= left

a= total allowance

12= (a/2) +4

-4            -4

8= a/2

multiply both sides by 2 to cancel the denominator

a= $16

she had an allowance of $16

9.  4 (2) = amount that her four children recieved

10=amount she took for herself

x= original

x= 4(2) + 10

x= 8 +10

x=18

she started with 18 candies

10. a= age

244= 400 - 2a

-400 -400

-156= -2a

/-2     /-2

a= 78

they are 78 years old

11. c= comic books

36=  c/2 + 16

20=c/2

multiply both sides by 2 to cancel the denominator

c=40

she started with 40 comic books

12.  b= students in buses

472= 9b + 4

-4             -4

468=9b

/9     /9

b= 52

52 students went in each bus

13. h= hats

17= h/2 +5

-5          -5

12=h/2

multiply both sides by 2 to cancel the denominator

h=24

she had 24 hats on monday

14. p= pies the club made

60= (p+4)/5

multiply both sides by 5 to cancel the denominator

300=p+4

-4         -4

p= 296

the club made 296 pies

Answer:

Answer A

Step-by-step explanation:

In the equation [tex]\dfrac{10}{x^2-1}=\dfrac{15}{3x-3}[/tex], 1 makes the denominator zero and 1 is the solution of the equation derived from cross multiplication.

Given :

Option A)

Given :

[tex]\dfrac{10}{x^2-1}=\dfrac{15}{3x-3}[/tex]

The above expression is not defined for x equal to 1 so, 1 is an extraneous solution.

Simplify the above equation by doing the cross multiplication.

[tex]10(3x-3)=15(x^2-1)[/tex]

[tex]30(x-1)=15(x-1)(x+1)[/tex]

2 = x + 1

x = 1

In the given equation 1 makes the denominator zero and 1 is the solution of the equation derived from cross multiplication.

Therefore, the correct option is A) and therefore, no need to check the other options.

Answer:

The slope is 3

The y-intercept is -2

The linear equation is y = 3x - 2

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

∵ A line passes through points (2, 4) and (6, 16)

∴ x1 = 2 and y1 = 4

∴ x2 = 6 and y2 = 16

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{16-4}{6-2}[/tex] = [tex]\frac{12}{4}[/tex] = 3

∴ m = 3

→ Substitute it in the form of the equation above

∴ y = 3x + b

→ To find b substitute x and y in the equation by the coordinates of

   a point on the line

∵ Point (2, 4) is on the line

∴ x = 2 and y = 4

∵ 4 = 3(2) + b

∴ 4 = 6 + b

→ Subtract 6 from both sides to find b

∵ 4 - 6 = 6 - 6 + b

∴ -2 = b

→ Substitute its value on the equation above

∵ y = 3x + (-2)

∴ y = 3x - 2

→ Let us answer the questions

The slope is 3

The y-intercept is -2

The linear equation is y = 3x - 2

Answer:

[tex]\frac{2+\sqrt{3} }{2}[/tex]

Step-by-step explanation:

Using the product to sum formula

sinxcosy = [tex]\frac{1}{2}[/tex] [ sin(x + y) + sin(x - y) ] , then

2sinxcosy = sin(x + y) + sin(x - y)

Given

2sin75°cos15° ← with x = 75 and y = 15 , then

= sin(75 + 15) + sin(75 - 15)

= sin90° + sin60°

= 1 + [tex]\frac{\sqrt{3} }{2}[/tex]

= [tex]\frac{2+\sqrt{3} }{2}[/tex]

Answer:

The slope is 1 1/3.

Step-by-step explanation:

[tex]m=\frac{y2-y1}{x2-x1} \\m=\frac{-1-(-13)}{3-(-6)}\\m=\frac{12}{9}\\m=\frac{4}{3}\\m=1\frac{1}{3}[/tex]
