Henry and Gavin win some money and share it in the ratio 5:3. Henry gets £14 more than Gavin. How much did they get altogether?
Answer:
Total amount = £56
Step-by-step explanation:
Let Henry and Gavin be H & G respectively.
Let Henry's and Gavin's share be x.
Given the following data;
Ratio of H to G = 5:3
Henry = G + £14
Translating the word problem into an algebraic expression, we have;
5x = 3x + 14
5x - 3x = 14
2x = 14
x = 14/2
x = £7
Next, we determine the amount earned by Gavin;
Gavin = 3x
Gavin = 3*7
Gavin = £21
For Henry;
Henry = G + £14
Henry = £21 + £14
Henry = £35
Now, to find the total amount earned by Henry and Gavin.
Total amount = H + G
Total amount = 35 + 21
Total amount = £56

Answer:
The y intercept is added to the new parent function.
Step-by-step explanation:
The parent function changed because the y intercept (SLOPE) was added into the new parent function. In order to prove that the change took place with the y intercept being added to the function, you can use any value from 2 and up.
Completion of substitution for X:
Original parent function: Plug in 2 for x
(2)^3 = 8
Completion of substitution for X with NEW parent function: plug in 2 for x
(2)^3 + 2 = 10

Use the expression
to find the length of each
section.
Each section of rope is meter long.
Answer:
1 foot
Step-by-step explanation:

3 feet divided by 3 = 1 foot
The length of each section of the rope is 1 foot.
What is an expression?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.Many authors make a distinction between an expression and a formula, with the former designating a mathematical object and the latter a claim about such objects.Solution -The piece of rope is 1m long.
Carter divided the ropes into three equal parts by tying up the knot.
1 meter = 3 foot.
Therefore, divide 3 by 3.
[tex]\frac{3}{3} =1[/tex] foot.
Therefore, each section is 1 foot long.

Answer:
Step-by-step explanation:
6. x² + 8x + 7
= x² + 7x + x + 7
= x (x + 7) + 1 (x + 7)
= (x + 1) (x + 7)
Option D is the answer.

= x² - 9x + 8x - 72
= x(x - 9) + 8(x - 9)
Option B is the answer.

Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations
Answer:
(-4, -3)
Step-by-step explanation:
Using elimination by addition and subtraction works best here.
Suppose we decide to eliminate x temporarily. To do this, we multipy the first row by 4, obtaining
-12x + 28y = -72
4x - 4y = 8
Next, multiply the second row by 3, obtaining the "equivalent system"
-12x + 28y = -72
12x - 12y = 24
Combining these equations, column by column, we get:
16y = -48. So y = -3.
Now let's find x. Substitute -3 for y in the second equation:
4x - 4(-3) = 8, or
4x + 12 = 8, or
4x = 8 - 12 = -4. This tells us that x = -4.
The solution is thus (-4, -3).
Analyze this equation.

1A) Quad ABCD is inscribed in the circle. Find x. *
1B) Using your answer from above, what is angle A? *
Step-by-step explanation:
2x + 9° + 3x + 1° =180° (opposite angles of a cyclic quadrilateral are supplementary)
5x + 10° = 180°
5x = 180° - 10°
5x = 170°
x = 34°
Now
Angle A
= 2 * 34° + 9°

Answer:
x=23
Step-by-step explanation:
let's make this question into equation form
x increase by 10; or x+10
is equal to 33; or =33
so it would look like this; x+10=33
now we can solve it in reverse
33-10=23 so x is 23.

Anyone good at geometry proofs? Help with math please. Thank you!
Answer and Step-by-step explanation:
1. Given
This part is given at the beginning of the problem.
2. Corresponding Angles Postulate
Because the lines are parallel, these two angles will be congruent by the corresponding angles postulate.
3. Same-Side Interior Angles Theorem
The same-side interior angles theorem has it so that the angles within parallel lines will add up to 180.
4. Substitution
We can use substitution here because we already determined that the measure of angle UTY is congruent to the measure of angle HGY.
I hope this helps!
#teamtrees #PAW (Plant And Water)
Answer:
Below.
Step-by-step explanation:
m <UTY + m <UTR = 180 degrees ( Angles on a straight line YR)
But m < UTR = m<RWX ( Corresponding angles in the parallel lines SU and VX)
So substituting for m< UTR in the first equation:
m <UTY + m<RWX = 180.
Work out the area of the trapezium ABDE.
A
В.
7.5 cm
2.5 cm
С
5 cm
E
Answer:
Area = 50 cm²
Step-by-step explanation:
Area of a trapezium ABDE = ½(a + b)h
where,
a = BD = 2.5 cm
b = AE = 7.5 cm
h = DE = ?
We need to find DE ti be able to calculate the area.
DE = CE - CD
DE = CE - 5
Since ∆ACE is similar to ∆BCD, therefore:
AE/BD = CE/CD
Plug in the values
7.5/2.5 = CE/5
Cross multiply
CE*2.5 = 7.5*5
CE*2.5 = 37.5
Divide both side any 2.5
CE = 37.5/2.5
CE = 15
Thus, DE = CE - 5 = 15 - 5
DE = 10
✅Area of trapezium = ½(BD + AE)DE
= ½(2.5 + 7.5)*10
= ½(10)10
= 50 cm²
