The answer is x > 3
I got this answer bc I am already in college and it it the correct answer and it’s really easy
-7x+y=42
y=42+7x
5x+13y=66
Substitute for y (meaning put 42+7x into the equation above instead of y because they are equal - see second line of my answer above)
5x+13[42+7x] = 66
5x +546 = 66
5x=66-546
5x=-480
x=-480/5
x=-96
Answer:
$22.40
Step-by-step explanation:
For this question you have to use decimal multipliers to work out the sale price of the cola given the information that in a grocery store, a $32 case of soda is labelled get a 30 % discount so to use decimal multipliers we have minus 100 by 30 and then divide by 100
→ We have to minus 100 by 30
⇒ 70
→ And then divide by 100
⇒ 70 ÷ 100 = 0.7
0.7 is the decimal multiplier for this question so we multiply it by the case of soda price with is $32 so
32 × 0.7 = 22.4
The sale price of the case of soda is $22.40 considering a 30% discount on a $32 case of soda
Answer:
B
Step-by-step explanation:
Because to add fraction you must make all of the denominators the same and in the same i mean have to be same LCM (least common multiple)
