Answer:

120°

Step-by-step explanation:

m<ABD+m<DBC=m<ABC

61°+59°=120°

hope this helped!

Answer:

We conclude that the value of m∠ABC = 120°

Step-by-step explanation:

Given

m∠ABD = 61°

m ∠DBC = 59°

To Determine

m∠ABC = ?

It is clear that the value of m∠ABC can be determined by adding m∠ABD and m∠DBC because m∠ABC the segment BD divides the angle m∠ABC into two adjacent angles m∠ABD and ∠DBC.

Therefore,

m∠ABC = m∠ABD + m∠DBC

             = 61° + 59°            ∵ m∠ABD = 61°, m ∠DBC = 59°

             = 120°

Therefore, we conclude that the value of m∠ABC = 120°

Step-by-step explanation:

Step 1: Define

-12(x + 4) + 14x = 60

Step 2: Solve for x

Answer:

x = 54

Step-by-step explanation:

-12(x + 4) + 14x = 60

i) distribute -12 to the whole parentheses of (x+4)

(-12 × x) + (-12 × 4) + 14x = 60

-12x - 48 + 14x = 60

ii) collect like terms

-12x + 14x - 48 = 60

2x - 48 = 60

iii) move constant to the right-hand side and change its sign

2x = 60 + 48

iv) add the numbers

2x = 108

v) divide both sides of the equation by 2

[tex] \frac{2x}{2} = \frac{108}{2} [/tex]

x = 54

Answer:

the student is wrong

Step-by-step explanation:

the og directions said 3 scoops / 1 gallon / 1 pitcher. if you are using 12 scoops, then the gallons of water will be proportional, meaning 3x4=12 scoops / 1x4=4 gallons / 1x4=4 pitchers. if you x4 to one of them, then the directly porportinal values also have to be multiplied by the same number, hence making the student wrong since they should have 4 gallons for 12 scoops

Answer:

A)16/24

B)15/24

Step-by-step explanation:

We were told to rewrite so that the denominator will be 24

A)2/3

This can be rewritten as 16/24, so that the denominator is now 24. And if we divide the numerator (16) by factor of 8 and the denominator (24) by factor of 8. Then we have 2/3.

OR

[2/3 × 8/8] = 16/24

B)5/8

This can be rewritten as 15/24, so that the denominator is now 24. And if we divide the numerator (15) by factor of 3 and the denominator (24) by factor of 3. Then we have 5/8

OR

(5/8 × 3/3)= 15/24

Answer: d) b = 12

2/3.b - 1/3.b + 12 = 16

⇔ 1/3. b = 16 - 12

⇔ 1/3.b = 4

⇔ b = 4.3 = 12

Step-by-step explanation:

Answer:

b = 12

Step-by-step explanation:

2/3 b - 1/3 b + 12 = 16

or, 2b/3 - b/3 + 12 = 16

or, 2b -b/ 3 + 12 = 16

or, 2b - b = 16 - 12

or, b = 4 × 3

therefore, b = 12

YOUR ANSWER :- B. 45°.......

Answer:

x ≈ 25.1

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos64° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )

x × cos64° = 11 ( divide both sides by cos64° )

x = [tex]\frac{11}{cos64}[/tex] ≈ 25.1 (  to the nearest tenth )

Given:

The graph shows the relationship between the number of pounds of  apples purchased and the total cost of the apples.

To find:

The cost of 1 pound of apples.

Solution:

We need to find the slope of the line to get the cost of 1 pound of apples.

From the given graph it is clear that the line passes through two points (0,0) and (2,3). So, the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{3-0}{2-0}[/tex]

[tex]m=\dfrac{3}{2}[/tex]

[tex]m=1.5[/tex]

Therefore, the cost of 1 pound of apples is $1.5.

Complete Question

Mr Brown has 2 children are going to london by train

1 adult costs £24 and child ticket costs 12

The Family Railcard offers:

1/3 off adults tickets and 60% off child ticket

What is the total cost of tickets when Mr Brown uses the Family Railcard

Answer:

£25.60

Step-by-step explanation:

From the question:

1 adult costs £24

The Family Railcard offers:

1/3 off adults tickets.

Hence:

1/3 × £24 = £8

The cost for Mr Brown = £24 - £8

= £16

Child ticket costs £12

The Family Railcard offers:

60% off child ticket

Hence = 60% × £12

= 60/100 × £12

= £7.2

The cost for 1 child = £12 - £7.2

= £4.8

The total cost of tickets when Mr Brown uses the Family Railcard is:

Cost for Mr Brown + Cost for his 2 Children

£16 + 2 × £4.8

£16 + £9.6

= £25.60

Answer:

[tex](4,5)\ or\ x=4,y=5[/tex]

Step-by-step explanation:

[tex]We\ are\ given:\\y=2x-3\\y-9=-x\\Now,\ lets\ separate\ all\ the\ constant\ terms\ to\ the\ RHS\ and\ the\ variable\\ terms\ to\ the\ LHS.\\Hence,\\y-2x=-3\\y+x=9\\By\ subtracting\ the\ two\ equations:\\(y-2x)-(y+x)=(-3)-(9)\\Hence\ lets\ simplify\ this\ main\ equation: \\y-2x-(y+x)=-3-9\\y-2x-y-x=-12\\-3x=-12\\x=\frac{-12}{-3}=4\\\\Now,\ lets\ consider\ the\ second\ equation\ in\ the\ solution:\\y-9=-x\\Substituting\ x=4,\\y-9=-(4)\\y-9=-4\\y=-4+9\\y=5\\[/tex]

[tex]Now,\\We\ get\ the\ solution\ to\ this\ system\ of\ equations:\\x=4,y=5\\By\ putting\ this\ as\ a\ co-ordinate\ pair (x,y):\\(4,5)[/tex]

Answer:

The solution of the system of equations will be:

[tex]y=5,\:x=4[/tex]

Step-by-step explanation:

Given the system of equation

[tex]\begin{bmatrix}y=2x-3\\ y-9=-x\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y-2x=-3\\ y+x=9\end{bmatrix}[/tex]

so

[tex]y+x=9[/tex]

[tex]-[/tex]

[tex]\underline{y-2x=-3}[/tex]

[tex]3x=12[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}y-2x=-3\\ 3x=12\end{bmatrix}[/tex]

solve 3x=12 for x

[tex]3x=12[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}=\frac{12}{3}[/tex]

[tex]x=4[/tex]

[tex]\mathrm{For\:}y-2x=-3\mathrm{\:plug\:in\:}x=4[/tex]

[tex]y-2\cdot \:4=-3[/tex]

[tex]y-8=-3[/tex]

Add 8 to both sides

[tex]y-8+8=-3+8[/tex]

[tex]y=5[/tex]

Thus, the solution of the system of equations will be:

[tex]y=5,\:x=4[/tex]

Answer:

x = 16 treata

Step-by-step explanation:

Let us represent x = Number of treats that Tim can buy

We are told that: Tim does not want to spend more than $62.00 in all.

= Time wants to spend less than or equal to $62.00

Tim is going to an amusement park that cost $30.00 to get into.Treats like cotton candy carmel apples and funnel cakes cost 2.00 dollars each .

Therefore, our inequality equation =

$30.00 + $2.00 × x ≤ $62.00

30 + 2x ≤ 62

Solving for x

30 + 2x ≤ 62

2x ≤ 62 - 30

2x ≤ 32

x ≤ 32/2

x ≤ 16

Hence, Tim can buy no more than(less than or equal to ) 16 treats

Answer:

I (interest) = £ 2,080.17

Step-by-step explanation:

Perrie invests £25000 for 3 years in a saving account. She gets 2.7% per annum compound interest. Calculate the total amount of interest perrie will get after 3 years.

To solve the above question, we would use the Periodic compound interest formula

A = P(1 + r) ^t

Where P = Principal = £25000

r = Interest rate = 2.7 % = 0.027

t = time in years = 3 years

Hence:

A = £25,000( 1 + 0.027)³

A = £27,080.17

A = P + I where

P (principal) = £ 25,000.00

I (interest) = £27,080.17 - £ 25,000.00

I (interest) = £ 2,080.17

The total amount of interest perrie will get after 3 years is £ 2,080.17
