3x+2y+2x+2=3x+2x+2y+2

Mathematics
1 answer:
White raven [17]3 years ago
5 0

Answer:

y=y

Step-by-step explanation:

Assuming the question is to simplify:

Add 3x and 2x on the left side

5x+2y+2=3x+2x+2

Add 3x and 2x on the right side

5x+2y+2=5x+2y+2

Move all terms containing x to the  left side of the equation

Subtract 5x from both side

5x+2y+2-5x=2y+2

x cancel out

2y+2=2y+2

Moving the constant to the right side of the equation

2y=-2+2y+2

Simplify

2y=2y

Divide 2

y=y

Plz help me i have 12 mins left i beg you
hram777 [196]

Answer:

x= 70 degrees

y= 30 degrees

z= 20 degrees

Step-by-step explanation:

Angle x will be supplementary to the 110 degree angle adjacent to it since it will form a straight line. 180 - 110 = 70 degrees.

Since we know the other two angle measures in the triangle that angle y is in, we can do 180 - (110 + 40) to find angle y. 180 - 150 = 30 degrees

We also know the other 2 angle measures of the triangle that angle z is in. We can find angle z by doing 180 - (70 + 90). 180 - 160 = 20

Final question - whats the answer?
Doss [256]

Answer: 7^5 or 7 to the fifth power.

Step-by-step explanation: This is an exponent meaning you count the 7’s and in the first picture there’s 5 7’s. This means that the number your putting to a power is the yellow box so that’s 7 and the exponent is 5 not 4 because if you did 7 to the first power it’s still 7 so it would be 7 to the 5th power or 7^5

The 6 term of a G.P is -2\27 and it's first term is 18.what is the common ratio​
Airida [17]

Answer:

r = - \frac{1}{3}

Step-by-step explanation:

The n th term of a GP is

a_{n} = a₁ r^{n-1}

where a₁ is the first term and r the common ratio

Here a₁ = 18 and a₆ = - \frac{2}{27} , then

18 r^{5} = - \frac{2}{27} ( divide both sides by 18 )

r^{5} = - \frac{1}{243} ( take the fifth root of both sides )

r = \sqrt[5]{-\frac{1}{243} } = - \frac{1}{3}
