Answer:

Yes, AA~

Step-by-step explanation:

because 2 of the angles are the same (90 and 52) they have to be the same. The triangle on the right is known to be 90 degrees because 52+38 is 90 and 180-90 is 90 and a triangle has to add up to 180 degrees

Solve this system of equations: 5x + y = 7 20x + 2 = y

xz_007 [3.2K]

Answer:

x = 1/5, y = 6

Step-by-step explanation:

5x + y = 7

y = 7 - 5x

Set equations equal to each other to eliminate y

7 - 5x = 20x + 2

7 = 25x + 2

5 = 25x

x = 1/5

y = 7 - 5(1/5)

y = 7 - 1

y = 6

To solve the equation, Antwan uses the distributive property, combines like terms, then uses the addition and subtraction proper

nikdorinn [45]

Answer:

The value of x is $-\frac{28}{5}$ .

Step-by-step explanation:

The distributive property is:

a (b + c) = a · b + a · c

The expression is:

$3(\frac{1}{3}x+1)+4=-1-4(x+3)-3$

Solve using the distributive property as follows:

$3(\frac{1}{3}x+1)+4=-1-4(x+3)-3$

$(3\cdot \frac{1}{3}x)+(3\cdot 4)=-1-(4\cdot x)-(4\cdot 3)-3\\\\x+12=-1-4x-12-3\\\\x+4x=-16-12\\\\5x=-28\\\\x=\frac{-28}{5}$

Thus, the value of x is $-\frac{28}{5}$ .
