4 + 3 = 7, 7 + 7 = 14, 7 + 0 = 7, 7 + 7 = 14. 14 = 14 Fourteen is equal to fourteen so the answer is =
Answer:
2.52= x
Step-by-step explanation:
Answer:
Let the larger number = y and the smaller number = x.
The largest number is 10 less than twice the smaller number. Remember that less than means subtract the 10 from the other amount while twice means multiply by two. Therefore,
y = 2x - 10
The sum of the two numbers is 38. Remember sum means add the two numbers to get their result. Therefore,
x + y = 38
Since y = 2x - 10, we rewrite the lower equation as:
x + (2x - 10) = 38
Solving:
3x - 10 = 38
3x = 48
x = 16
The lesser number is 16 and the greater number is 2(16) - 10 or 22.
The solution to the question how much was the total cost for the seminar is shown below:
Cost 1 = $ 340 for the total wages for the group
cost 2 =$5 x 5 employees, this is for the refreshments
cost 3 = $75 for the instructors fee
cost 4 = $250 for the supplies and others
Total cost = cost1 +cost2 +cost3 + cost 4
Total cost = $340 + ($5*5) + $75 + 250
Total cost = $690
Make x=0 in the second equation, giving you y=-3. If you plug that in to the top equation you would get x-3(-3)=-19, x+9=-19,x=-28.
