Answer:

Kato must write 12 pages of the report

Step-by-step explanation:

We have given that total number of pages in report = 20

It is given that Kato must write 60 % of the that report tomorrow

We have to find the number of pages which kato write tomorrow

So number of pages which kato write tomorrow =\frac{20\times 60}{100}=12

So kato must write write 12 pages of the report tomorrow because 60 % of 20 is 12

The two equal sides of an isosceles triangle is thrice the third side. If the perimeter is 35 cm, then the length of equal sides
DedPeter [7]

Answer:

5

Step-by-step explanation:

First the question said that two equal sides of the isosceles triangles is thrice the third side. This means that the two equal sides is 3x while the third side should be represented as x

Secondly, add the three parts together which = 3x+3x+x =7x

Thirdly, then divide both sides by 7= 7x/7 *35/7

Making x=5

Please help, you don't have to show your work. Like at all.
elixir [45]

The slope of the line is -2.

Solution:

Given points are (-3, -7) and (2, -17).

Here x_1=-3, y_1=-7, x_2=2, y_2=-17

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{-17-(-7)}{2-(-3)}

$m=\frac{-17+7}{2+3}

$m=\frac{-10}{5}

m = -2

The slope of the line that passes through the pair of points is -2.

2x - 7y = 2 and 3x + y = -20 addition/elimination
Mkey [24]

Answer:

x = -6, y = -2

Step-by-step explanation:

2x-7y = 2

3x + y = -20

We need to cancel out either x or y to solve the equation. I'll cancel out x first

3(2x-7y = 2)

-2(3x+y=-20)

___________

6x-21y = 6

-6x -2y = 40

____________

-23y = 46

y = -2

Plug the value for y in one of the 2 equations to solve for x

2x -7(-2) = 2

2x+14=2

2x = -12

x=-6
