Answer:
<u>x = √10</u>
Step-by-step explanation:
x² - 10 = 0
x² = 10
<u>x = √10</u>
Answer:
z = (3/8)y - 11
Step-by-step explanation:
Undo what has been done to z, in reverse order. Here, 11 is added and the sum is multiplied by 8/3.
To undo the multiplication, multiply the equation by the inverse, 3/8:
(3/8)(8/3)(z+11) = (3/8)y
z +11 = (3/8)y . . . . . . . . . simplify
To undo the addition of 11, add the opposite of 11 to the equation.
z +11 -11 = (3/8)y -11
z = (3/8)y -11 . . . . . . . . . simplify
Let h = the $ Hope makes
Let t = the $ Tristan makes
a. h + t = 345
h = 35 + t
b. (35 + t) + t = 345
35 + 2t = 345
2t = 345 - 35
2t / 2 = 310 / 2
t = 155
h = (155) + 35
h = 190
c. graph above ^^ the point where they cross is the answer to the problem
Answer:
x = 60
Step-by-step explanation:
For L and M to be parallel then
2x + 5 and x - 5 are same- side interior angles and sum to 180° , then
2x + 5 + x - 5 = 180 , that is
3x = 180 ( divide both sides by 3 )
x = 60
4x+2=19
Step 1. Subtracting 2 from both sides,
4x+2-2=19-2
4x=17
Step 2. Dividing 4 from both sides,
x=17/4
