Answer:
The solution of given expression = 5 , -3
Step-by-step explanation:
Given expression;
15 - 4x = x² - 6x
Find:
The solution of given expression
Computation:
15 - 4x = x² - 6x
x² - 6x + 4x - 15 = 0
x² - 2x - 15 = 0
x² - (5 - 3)x - 15 = 0
x² - 5x + 3x - 15 = 0
x(x - 5) + 3(x - 5) = 0
(x - 5)(x + 3) = 0
So,
x - 5 = 0 and x + 3 = 0
x = 5 and x = -3
The solution of given expression = 5 , -3
9w + 45 = 126
Ivan earns $9 per week so we would write it as 9w
Add 45 to it because that is what he also saved
Then he spent those savings which was 126.
Now we can find how many weeks he was saving for.
First minus 45 from both sides
9w = 126 - 45 = 81
The divide both sides by 9
w = 9
Ivan has been saving for 9 weeks
Answer:
D. 15G > 9
Step-by-step explanation:
Given: G = 3/5
Here we have to check each options and find which is true.
Let's start from A.
G - 1 > 2/5
G > 2/5 + 1
G > 7/5 is not true.
B. -10G > 6
Dividing both sides by -10 , we get
G < -6/10
G < -3/5 Is not true.
C. 1 2/5 + G > 3
Now convert 1 2/5 to improper fraction.
1 2/5 = 7/5
7/5 + G > 3
G > 3 - 7/5
G > (15 - 7)/5
G > 8/5 is not rule.
D. 15G > 9
Dividing both sides by 15, we get
G > 9/15
Now we have to simplify 9/15
G > 3/5 which is true.
Answer: D. 15G > 9
