Answer: yes , it is possible
Step-by-step explanation:
Let the first number be x and the second number be y .Then , the sum of the two numbers will be x + y , and their difference will be x - y.
Combining the two , we have :
x + y = 1 ............................... equation 1
x - y = 8 ................................. equation 2
solving the system of linear equation by substitution method. From equation 1 , make x the subject of the formula ,
x = 1 - y ...................... equation 3
Substitute equation 3 into equation 2 ,
1 - y - y = 8
1 - 2y = 8
add 2y to both sides
1 = 8 + 2y
subtract 8 from both sides
1 - 8 = 2y
- 7 = 2y
divide through by 2
y = 
y = - 3.5
substitute y = -3.5 into equation 3 to find the value of x , we have
x = 1 - y
x = 1 - ( - 3.5 )
x = 1 + 3.5
x = 4.5
Let us check :
x + y will be
4.5 + (-3.5) = 1
Also ,
x - y will be
4.5 - (-3.5)
⇒ 4.5 + 3.5 = 8
The question is asking us to find how much seven tomatoes would cost. Well, to get our answer, we must first find the cost of one tomato. We are given the information that paying $4.16 for 4 tomatoes. All we have to do now is divide 4.16 by 4, to get the price of one tomato. This gives us $1.04. Now, just multiply 1.04 by 7 to get 7.28. Therefore, the price of seven tomatoes is C. $7.28. Hope this helped and have a phenomenal day!
It is three hundred fifty-six thousandths.
Answer:
84 is .4 of the trip
40% times 2.5 is 100% (40+40+20)
so, multiple 84 by 2.5 and that's the answer
84 * 2.5= 210
