Answer:

Yes

Step-by-step explanation:

Congruent means equal in shape and size. It does not refer to orientation or if it is turned a certain way. If you turned the green triangle on the right to where the 7cm measurement is on the bottom and the 5cm is to the left, and the 9cm to the right, the triangles would look exactly the same. As well as the angles corresponding to the sides, for example, the 85' is between the 5cm and 7 cm on both triangles, and the 60' is between the 5cm and 9cm on both as well.

How can I solve 2t+4w=6 + 4t +6w= 15 using elimination?

xeze [42]

I hope this helps you

-2/2t+4w=6

-4t-8w= -12

4t+6w=15

-2w=3

w= -3/2

2t-4.3/2=6

2t=12

t=6

Consider the graph shown.

otez555 [7]

Answer:

y = $\frac{2}{3}$ x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, 4)

m = $\frac{4-2}{3-0}$ = $\frac{2}{3}$

The line crosses the y- axis at (0, 2) ⇒ c = 2

y = $\frac{2}{3}$ x + 2 ← equation of line

A device in your school Lab releases gas at a rate of, which means 0.25 of a liter of gas is released every second. The density

Snezhnost [94]

Answer:

143.26 sec

Step-by-step explanation:

Density = 4.3 g/l

Volume flow rate = 0.25 l/s

Mass flow rate = density x volume flow rate

= 4.3 x 0.25 = 1.075 g/s

This means 1.075 grams of the gas is released in 1 sec, therefore,

Time taken for leakage of 154 g of gas is

t = 154/1.075 = 143.26 sec
