[tex]~~~~9x=28-5x\\\\\implies 9x +5x = 28\\\\\implies 14x = 28\\\\\implies x = \dfrac{28}{14}\\\\\implies x = 2[/tex]
Step-by-step explanation:
Given Equation,
[tex]\\ \longrightarrow \qquad \sf 9x=28-5x \\ \\ [/tex]
Now, Adding 5x to both sides we get :
[tex]\\ \longrightarrow \qquad \sf 9x + 5x=28-5x + 5x \\ \\ [/tex]
[tex] \longrightarrow \qquad \sf 14x=28 \\ \\ [/tex]
Dividing 14 from both sides we have :
[tex]\\ \longrightarrow \qquad \sf \frac{14x}{ 14 } = \frac{28}{14} \\ \\ [/tex]
[tex] \longrightarrow \qquad \sf x=2 \\ \\ [/tex]
Therefore,
The value of x is 2

let us first start with some basic information ~
A fraction can be represented as [tex]\frac{x}{y}\\[/tex] where ,
x is the numerator and y is the denominator !
the question asks us to do something that will help us get same denominator for both the terms !
so let's see what we should do in such a case ~
[tex] \frac{9}{10} \: and \: \frac{7}{8} \\ \\ \\ lets \: make \: the \: denominator \: of \: both \\ the \: terms \: reach \: 80 \: , \\ \\ \bold\orange{ \implies \: \frac{9}{10} \times \frac{8}{8} = }\bold\red{ \frac{72}{80}} \\ \\\bold\orange{ \implies \: \frac{7}{8} \times \frac{10}{10} =}\bold\red{ \frac{70}{80}} [/tex]
and we're done !
let's add some more info to be lil more clear ~
while converting the denominator of both the terms , we must multiply the same number ( this number refers to the one we'll have to multiply to the denominator to obtain the desired result ) with the denominator as well as with the numerator !

Step-by-step explanation:
you have to multiply first fraction with '8' and second fraction with '10' :
the fractions will become 72/80 and 70/80 then you can compare it
what is the area of a 14cm square?
Answer:
196
Step-by-step explanation:
the area of a square is simple its just a=length time width, so you just plug in youre length which is 14 and a square side are all the same size so the width is also 14, so your equation is a=14 times 14= 196. ;) hope that helped.

Step-by-step explanation:
the law of sine
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and associated angles are always opposite to each other.
and the sum of all angles in a triangle are always 180°.
sin(90) = 1.
4.
there are multiple solutions, as the direction they are going has no relevance to their position to each other right now.
and the angles of depression can be forward or backwards of the plane.
the larger the angle of depression, the closer the ship is.
for the closer ship we get
height/sin(35) = ground distance / sin(180-90-35)
265/sin(35) = ground distance / sin(55)
ground distance (plane to closer ship) =
= 265×sin(55)/sin(35) = 378.4592218... m
for the farther ship we get
height/sin(25) = ground distance / sin(180-90-25)
265/sin(25) = ground distance / sin(65)
ground distance (plane to closer ship) =
= 265×sin(65)/sin(25) = 568.2943339... m
the distance of both ships is
568.2943339... - 378.4592218... = 189.8351121... m
now, this distance applies to the case, where both ships are on the same side of the plane.
if they are on different sides of the plane, then we need to add their individual distances from the plane to get the distance of both ships from each other :
568.2943339... + 378.4592218... = 946.7535557... m
5.
another right-angled triangle.
the string is the Hypotenuse (baseline).
the height and the ground distance are the legs.
so, we get
100/sin(90) = height/sin(52) = 100
= ground distance / sin(180-90-52)
height = 100×sin(52) = 78.80107536... m
ground distance = 100×sin(38) = 61.56614753... m

Solve using the Elimination Method
x - 2y = 4
3x + 4y = 2
Answer: x=2, y=-1
Step-by-step explanation:
Step 1) Make both equations have the same coefficient
What I mean by this is make either y or x have the same number multiplied to them so that we can eliminate. We can do this by multiplying everything in the first equation by 2.
[tex](2)x - (2)2y = (2)4\\2x-4y=8[/tex]
Step 2) Add the equations together to eliminate y
[tex]2x - 4y = 8\\+3x + 4y = 2\\5x+0=10\\5x=10[/tex]
Step 3) Solve for x
[tex]\frac{5x}{5} =\frac{10}{5} \\x=2[/tex]
Step 4) Sub the value of x into an equation and solve for y
[tex]x-2y=4\\2-2y=4\\2-2-2y=4-2\\-2y=2\\\frac{-2y}{-2} =\frac{2}{-2} \\y=-1[/tex]
Is a triangle with the side lengths 4 feet, 7. 5 feet, and 8. 5 feet a right triangle? Why or why not?
Answer:
Yes
Step-by-step explanation:
You can test if a triangle is right-angled by using Pythagoras' Theorem.
So:
[tex]4^2 + 7.5^2 = 8.5^2[/tex]
16 + 56.25 = 72.25
They do in fact add up so this triangle is right angled.
The parabola in the image has its focus at (4,3).Its directrix is the line y=1.The point (8,6) is on the parabola.
The true statements for the parabola in the image are:
C. The point (8, 6) is the same distance from the point (4, 3) as it is from the line y = 1.Option D.How to determine the equation of the directrix?Mathematically, the standard equation of the directrix lines for a parabola is given by y = a(x - h)² + 2.
Given the following data:
Vertex (h, k) = (4, 3).
Point (x, y) = (8, 6).
Next, we would determine the distance where point (8, 6) lies on the parabola:
y = a(x - h)² + 2
6 = a(8 - 4)² + 2
6 = a(4)² + 2
6 = 16a + 2
16a = 6 - 2
16a = 4
a = 4/16
a = 1/4.
Therefore, the equation becomes:
y = 1/4(x - 4)² + 2
When x = 2, we have:
y = 1/4(2 - 4)² + 2
y = 1/4(-2)² + 2
y = 1/4(4) + 2
y = 1 + 2
y = 3.
In conlusion, the true statements regarding the parabola in the image are:
The point (8, 6) is the same distance from the point (4, 3) as it is from the line y = 1.The point (2, 3) is on the parabola.Read more on directrix here: https://brainly.com/question/2346582

Answer:
BC = 4.5 (1 dp)
Step-by-step explanation:
Pythagoras’ Theorem
[tex]a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = AC = 1.5b = AB = 4.2c = BCSubstituting these into the formula and solving for BC:
[tex]\implies 1.5^2+4.2^2=BC^2[/tex]
[tex]\implies 2.25+17.64=BC^2[/tex]
[tex]\implies BC^2=19.89[/tex]
[tex]\implies BC=\pm\sqrt{19.89}[/tex]
As distance is positive,
⇒ BC = 4.5 (1 dp)
