4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5
Answer:
9 4/7
Step-by-step explanation:
First, we need to make as many 7s as possible. If we do 67/7, we will get 9...... so our whole number is 9. If we do 7 x 9, we get 63 and if we subtract 63 from 67, we are left with 4. All in all, we will get 9 4/7!
Answer:
4 + 1 + 20 + 100 = 1000
5 + 20 + 100 = 1000
25 + 100 = 1000
125 = 1000
The equation would be false because 125 does not equal 1000
Step-by-step explanation:
Answer:
166⅓ %
Step-by-step explanation:
250/150 × 100
500/3 = 166⅓ %
Or 166.67%
The equation given in the question is
2x - 3y = 6
Dividing both sides of the equation by 3, we get
2/3 x - y = 2
y = 2/3 x - 2
Then, from the above equation we can tell that the slope of the line in the graph is 2/3. The slope of a line perpendicular to this slope will be - 3/2. The line also contains the points (-2,-3).
Then, the equation of the perpendicular line will be
y = mx + b
- 3 = (- 3/2)(- 2) + b
- 3 = 3 + b
b = - 6
Then
y = (-3/2)x - 6
y + 6 = (- 3/2)x
2y + 12 = - 3x
3x + 2y = - 12
