Steps for solving 3x+18=54 are shown explain how step 1 helps solve the equation

Mathematics
1 answer:
Dennis_Churaev [7]3 years ago
4 0

Answer:

The answer is x=12.

Step-by-step explanation:

First, to solve this equation you need to isolate the x variable. To isolate the variable, you must, subtract the other term from both sides. Subtracting 18 from both sides, you are left with 3x = 36. Since 3 times x = 36, dividing both sides by 3 gets you, x=12.

The midpoint, M , of segment AB has coordinates (2,−1) . If endpoint A of the segment has coordinates (−3,5) , what are the coor
lbvjy [14]

the coordinates of endpoint B are (7,7)

Answer:

Solution given:

M(x,y)=(2,-1)

A(x_{1},y_{1})=(-3,5)

Let

B(x_{2},y_{2})=(a,b)

now

by using mid point formula

x=\frac{x_{1}+x_{2}}{2}

$ubstituting value

2*2=-3+a

a=4+3

a=7

again

y=\frac{y_{1}+y_{2}}{2}

$ubstituting value

-1*2=5-b

b=5+2

b=7

the coordinates of endpoint B are (7,7)

Trigonometry<br> Special Right Triangles<br> Find the exact value of tan 30* + sin 90* + cot 60*.
fredd [130]

Answer:

1 + 2sqrt(3)/3

Step-by-step explanation:

tan(30) = sqrt(3)/3

sin(90) = 1

tan(60) = sqrt(3)

cot(60) = 1/sqrt(3) = sqrt(3)/3

sqrt(3)/3 + 1 + sqrt(3)/3

1 + 2sqrt(3)/3
