Answer:
x = 1
Step-by-step explanation:
Solve for x:
4 x + 1 + 3 = 8
Hint: | Group like terms in 4 x + 1 + 3.
Grouping like terms, 4 x + 1 + 3 = 4 x + (1 + 3):
4 x + (1 + 3) = 8
Hint: | Evaluate 1 + 3.
1 + 3 = 4:
4 x + 4 = 8
Hint: | Isolate terms with x to the left hand side.
Subtract 4 from both sides:
4 x + (4 - 4) = 8 - 4
Hint: | Look for the difference of two identical terms.
4 - 4 = 0:
4 x = 8 - 4
Hint: | Evaluate 8 - 4.
8 - 4 = 4:
4 x = 4
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 4 x = 4 by 4:
(4 x)/4 = 4/4
Hint: | Any nonzero number divided by itself is one.
4/4 = 1:
x = 4/4
Hint: | Any nonzero number divided by itself is one.
4/4 = 1:
Answer: x = 1
Answer:
195
Step-by-step explanation:
Of means multiply and is means equals
40% * number = 78
Change to decimal form
.40 * number = 78
divide each side by .40
.40 number/ .40 = 78/ .40
number =195
Answer:
<h3>A (3, 1)</h3>
Step-by-step explanation:
If we have the coordinate (x,y), if this coordinate is rotated by 180 degrees clockwise, the resulting coordinate will be expressed as (-x, -y) i.e the original coordinate axis are both negated.
Given the coordinate C(-3, -1), if this coordinate is rotated clockwise about the origin, the coordinate of the resulting point will be at C' (-(-3), -(-1))
C' (-(-3), -(-1))
C' = (3, 1)
Hence option A is correct
