Consider this solution:
the only solution is (-1;-1), it is intersection point.
Answer:
Step-by-step explanation:
121+7x-4=180
7x-4=180-121=59
7x=59+4=63
x=63/7
x=9
It will be nice if you give me brainliest. Good luck!
12 goes into 187 15 times evenly. So the answer to fill the box is 180 (12*15)
Since 7 out of 8 people use crust toothpaste, in a city with the population of 40,000, 87.5% of the people use crust. so 40,000*87.5%= 35,000.
A) x = 0.296
B) x= 15
Step-by-step explanation:
Step 1:
(2/3) : x :: 4.5 :2
By using expansion method,
(2/3) × 2 = 4.5 x
x= (2/3) × 2 / 4.5
x = 0.296
Step 2:
(2/3) : (1/5) :: 50 :x
By using expansion method,
(2/3) x = (1/5) × 50
x= (1/5) × 50 / (2/3)
x = 15
