Answer:
3/4 or 0.75
Step-by-step explanation:
1. Cross multiply: (1/2) / (3/4)
2. 1 x 3 = 3 and 2 x 2 = 4
3. 3/4 or 0.75
Answer:
i think the answer is A
Step-by-step explanation:
Answer:
These have no solution:
- 2x < x+1 and x+1 > 3
- 3x -5 > 1 and x < 2
Step-by-step explanation:
1. 2x < x+1
x < 1 . . . . . subtract x
__
x + 1 > 3
x > 2 . . . . subtract x
No solution: x cannot be both > 2 and < 1.
_____
2. 3(x +2) > x
3x + 6 > x . . . . eliminate parentheses
2x + 6 > 0 . . . subtract x
x + 3 > 0 . . . . . divide by 2
x > 0
Solution: 0 < x < 2
_____
3. 5x ≥ 10
x ≥ 2 . . . . . divide by 5
__
2x ≤ 4
x ≤ 2 . . . . . divide by 2
Solution: 2 ≤ x ≤ 2 . . . . x = 2
_____
4. 3x -5 > 1
3x > 6 . . . . . . . add 5
x > 2 . . . . . . . . divide by 3
No solution: x cannot be both < 2 and > 2.
Answer:
2x - y = 0
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 1 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (1, 2) into the partial equation
2 = 2 + c ⇒ c = 2 - 2 = 0
y = 2x ← equation in slope- intercept form
Subtract y from both sides
0 = 2x - y , that is
2x - y = 0 ← equation in standard form
Answer:
Scale for drawing is 1:350
Step-by-step explanation:
scale is ratio of size of drawing and size of actual object for which the drawing is made
it is represented as
scale = size of drawing : size of actual object
given
length of model in drawing = 2cm
length of bedroom in reality = 7 meter
since there are two units we meter and cm
we convert both in same unit that is cm for simpler calculation
1 meter = 100 cm
7 meter = 7*100 cm = 700cm
length of bedroom in reality = 7 meter = 700 cm
Thus,
scale for drawing = length of drawing/ actual length of bedroom
scale for drawing = 2 cm : 700cm = 1:350
Scale for drawing is 1:350
