No. The value in the hundreds place represents 500, whereas the value in the tens place represents 50. The value in the hundreds place is 10 times as great as the value in the tens place.
Question 3) 5x-26=18x This is how the equation is written if you substitute numbers for words and x for unknown number. 18x-5x =13x divide everything by 13 to get x= -2
Question 4) 63-x=2x+3 add x to each side and subtract 3 from each side to get 60=3x divide by 3 to get x=20
Question 5) -30x= -27x-63 add -27x to each side to get -3x= -63. Divide everything by -3 to get x=21
Question 6) 12x-18= 18+13x subtract 12x from both sides to get -18=18+x subtract 18 from both sides to get x=-36
Hope this helps!
Answer:
Cost of one rocket = $1.5
Step-by-step explanation:
Given:
6 rockets and 11 bombs cost = $36.50
14 rockets and 8 bombs cost = $41
Find:
Cost of one rocket
Computation:
Cost of one rocket = x
Cost of one bomb = y
So,
6x + 11y = 36.50.....eq1
14x + 8y = 41......eq2
From eq1
y = [36.50 - 6x]/11
From eq2
14x + 8y = 41
14x + 8[36.50 - 6x]/11 = 41
x = 1.5
Cost of one rocket = $1.5
