Answer:
see explanation
Step-by-step explanation:
The 2 marked angles are vertical and congruent, thus
24x = 23x + 5 ( subtract 23x from both sides )
x = 5
Thus angles = 24 × 5 = 120°
Answer:
-7
Step-by-step explanation:
Let the number be represented with 'Y'
Half of the number will be = Y/2
The difference of half of a number and 3
= Y/2 - 3
Is equivalent to negative 5
That is,
Y/2 - 3 = -5
y/2-3/1 = -5/1
Collect like terms
y/2 = -5/1+3/2
y/2 = -7/2
Multiply both sides by 2
y/2 ×2 = -7/2×2
Y = - 7
Hence the number is negative 7
Answer:
here you go!!
Step-by-step explanation:
Answer:
X=1
Step-by-step explanation:
-10x-2=-3x-9
-10x-2+2=-3x-9+2
-10x=-3x-7
-10x+3x=-3x-7+3x
-7x=-7
Then divide both sides by -7
x=1
