2x+5=10-3x please help
Taya2010 [7]
Answer is 14x

Step by step

2x + 5 = 10 - 3x

Let’s start with 2x + 5 = 7 and you bring the x with you which is 7x

Now you do 7x = 10 - 3x , equal sign is plus am guessing and then 10 - 3x is 7x so

7x + 7x = 14x

Use the diagram and the value of x to find the measures of BCE and ECF.
stepan [7]

Answer:

125° and 55°

Step-by-step explanation:

∠ BCE and ∠ ECF are adjacent angles and are supplementary, thus

10x + 15 + 5x = 180, that is

15x + 15 = 180 ( subtract 15 from both sides )

15x = 165 ( divide both sides by 15 )

x = 11

Thus

∠ BCE = 10x + 15 = 10(11) + 15 = 110 + 15 = 125°

∠ ECF = 5x = 5(11) = 55°

Y = -x - 1 and y = 1/2x + k intersect at the point (-2,1). Find the value of k.
Lena [83]

Answer:

k = 2

Step-by-step explanation:

(-2,1) =  (x,y)   So you substitute -2 and 1 for x and y

1 = -(-2) - 1    1 = 1/2 × -2 + k

1/2 × -2 = -1       -1 + 2 = 1

k = 2           1 = 1/2 × -2 + 2


I hope this helps
