1.)The product of 14 and n is -28. Write the algebraic equation.
2.)Four times a certain number is the same as the number increased by 78
3.)A blue bike is $14 less than a red bike. The sum of their prices is $300. How much is the red bike
4.)Alex is six years older than his sister, Emma. The sum of their ages is 32. How old is Alex?
5.)Mrs. Computer is 3 times older than her daughter, Mousy. The sum of their ages is 52. How old is Mousy?
6.)Mike is 5 years more than twice as old as Tom. The sum of their ages is 65. How old is Mike
7.)The sum of three consecutive integers is 108. Which equation would be used to solve this word problem? (HINT: The equation has been simplified some..
8.)Find two consecutive odd integers whose sum is 72. Which equation would be used to solve this problem? (HINT: The equation has been simplified some
no ideas on any of these? Even with the hints?
1.) 14n = -28
6.) m = 2t+5
m+t = 65, so t=65-m
m = 2(65-m)+5
2) 4x = x - 78
3) b + r = 330 and b = r -14
These could be combinte by replacing the b with r - 14
r - 14 + r= 330
4) A = E + 6
A + E = 32
5) C = 3M
C + M = 52
6) n = 1st integer, n + 1 = 2nd and n+2 = the 3rd integer
sum is: n + n + 1 + n + 2= 105
7. Consecutive odd or consecutive even integers differ by 2. Example, 1, 3, 5 or 2, 4, 6
With this hint, can you figure this out. It is similar to 6.
