Step-by-step explanation:

First you need to find x.

It is shown that DE=EF, so we can use this.

5x-3=3x+7

5x=3x+10

2x=10

x=5

Then, you plug in the value of the variable and solve.

It takes 180 ml of fertiliser to treat 36 m² of lawn.
How much fertiliser is needed to treat a lawn of area 40 m²?​

Answers

Answer:

200 ml of fertilizer

Step-by-step explanation:

Create a proportion where x is the amount of fertilizer needed for an area of 40 m²

[tex]\frac{180}{36}[/tex] = [tex]\frac{x}{40}[/tex]

Cross multiply and solve for x:

36x = 7200

x = 200

So, 200 ml of fertilizer is needed

In right angled triangle ∆KJL

base[b]=10

hypotenuse [h]=x+10

perpendicular [p]=24

by using Pythagoras law

(x+10)²=676

x+10=√676

x=26-10

Write an explicit formula that represents the sequence defined by the following
recursive formula:
a1= -1 and an = an-1 – 6

Answers

Answer:

an = -6n + 5.

Step-by-step explanation:

This is an arithmetic sequence with first term a1 = -1 and common difference d = -6

an = a1 + d(n-1)

an = -1 + -6(n - 1)

an = -1 -6n + 6

an = -6n + 5.

UV = 9 ft

VW = 6 ft

WU = 5 ft

Step-by-step explanation:

The perimeter of a figure can be represented as the sum of lengths of all of its sides. In this case we can write:

P = UV + VW + WU

Now, we can substitute the values which we have:

20 = 4x + 1 + 8 - x + 2x + 1

We can combine like terms...

20 = 5x + 10

5x = 10

x = 2

Since UV is represented by 4x + 1, we can substitute in x to find its length.

UV = 4x + 1

UV = 4(2) + 1

UV = 6 + 1

UV = 9

We can do the same for the other two sides:

VW = 8 - x

VW = 8 - 2

VW = 6

WU = 2x + 1

WU = 2(2) + 1

WU = 4 + 1

WU = 5

Answer:

find the bottom angle of the triangle on the right side.

180 - 92 = 88

Now find x

88+36 = 124

180-124 = 56 = x

Hope that answers your question

Don't hesitate to comment if you are confused about something

Step-by-step explanation:

Hello :) to find the sum of angle X I would find the other missing angle in the triangle by subtracting 180 by 92 to get 88. Then add that angle and the other one which is 36 to get 124. The sum of all the angles in a triangle is 180 so to get the last angle aka angle X you would do 180-124. That equals 56 so X= 56 degrees. I hope I helped and if you need a better explanation lmk
