5x= 10/7
so 5x = 1.4
so x= 1.4/5
sk x= 0.28

5x = 10/7
x = (10/7) / 5
x = 10/7 * 1/5
x = 10/35 which reduces to 2/7 <==

Can I get some help on this math problem

pogonyaev

Answer:

$x=3\sqrt{5}$

Step-by-step explanation:

<u>Right Triangles</u>

Right triangles have one of its interior angles with a measure of 90°.

In right triangles the Pythagora's Theorem is satisfied.

Being c the longest side (hypotenuse), a and b the shorter sides (the legs), then:

$c^2=a^2+b^2$

We have modified the image to include some known data. Both triangles are congruent since they share one side, have a right angle, and have the same base length.

This means the value of x can be calculated as the hypotenuse of the triangle 3-6-x:

$x^2=3^2+6^2=9+36=45$

$x=\sqrt{45}=\sqrt{9*5}$

$\boxed{x=3\sqrt{5}}$

Can anyone help me with this?

Semmy [17]

Step-by-step explanation:

for a it's y=12x+60

for b it's y=1x+21

for c it would be) 40-70=-30/1-3=-2 and then divide -30/-2 is 15.

for d it would be y=20x+20

it would be ethier a or d

PLZZZZ HELPPPPPP EXTREME FROWNIES IF U DONT ITS MATTTTHHHH

STALIN [3.7K]

Answer:

x=9 and angle B=40

Step-by-step explanation:

5x-5=3x+13

Subtract -3 on both sides of x

5x(-3)-5=3x(-3)=+13

2x-5=13

Add 5 to both sides

2x-5(+5)=13(+5)

2x=18

Divide by 2

x=9

Now that you know x=9, plug it into 3x+13

So, 3(9)+13= 27+13= 40

so ya thats my answer hopefully it helps

(btw both angle A and B are the same so thats why u put them equal)
