Answer:
i dont uderstand sorry
Step-by-step explanation:
-10= 4x
divide both sides by 4 to get x by itself
-10/4=4x/4
x= -10/4
reduce the fraction by dividing by 2
-10/2= -5
4/2= 2
Answer:
x= -5/2, x= - 2 1/2 , x=-2.5
Answer:
67.5°, 107.5°
Step-by-step explanation:
For supplementary angles, their sum equals 180°.
Let x be the first angle and y be the second angle, then
x + y = 180°.
It is given that x = y + 45°.
So x + y = 180°
substituting x into the equation, we have
y + 45° + y = 180°
simplifying, we have
2y + 45° = 180°
collecting like terms, we have
2y = 180° - 45°
2y = 135°
dividing through by 2, we have
y = 135°/2
y = 67.5°
Since y = 67.5°
then x = y + 45°
x = 67.5° + 45°
x = 107.5°
Answer:
$120
Step-by-step explanation:
Let the cost of the dress be "c"
ONE HALF the cost DECREASED by 12, can be written as:
2/5th the cost of dress, can be written as:
Now, we equate both parts and solve for c to get cost of dress. Shown below:
Thus,
The ccost of the dress is $120
