If 3a+5b = 98 and a=11, what is the value of a +b a = 11: 3(11) + 5b = 98 33 + 5b = 98 Using our equation solver, we get: b = 13 a + b = 11 + 13 a + b = 24

A farmer has a total of 200 ducks and cows in his barn. If he has n cows, how many total legs are there in the barn? (Make sure you include the farmer.) Number of cows = n Legs per cow = 4 Cows legs = 4n Number of ducks = 200 - n Legs per duck = 2 Number of ducks legs = (200 - n) x 2 = 400 -...

There are cows and chickens in a barn along with a three-legged dog named Tripod. If there are twice as many chickens as cows, how many legs are there in the barn. (Call the number of cows n.) Number of cows = n Number of cows legs = 4n Number of chickens = 2n Number of chicken legs = 2*2n =...

Jon earned money baby-sitting. He spent 1/4 of the money on a guitar and then he gave 1/4 of what was left to charity. If he has $108 left, how much money did he start with? Calculate initial spend: Charity = 1/4 * 3/4 left = 3/16 1/4 + 3/16 = 7/16 This means he has 1 = 7/16 left 16/16 - 7/16 =...

When Mike uses a riding mower, it takes him 3 hours to mow his lawn. When he uses a push mower, it takes him 6 hours to mow the lawn. (His sister also can mow the lawn with the push mower in 6 hours.). Mike wanted to get the lawn mowed as quickly as possible, so he paid his sister $10 to mow...

you own 15 CDs. you buy 7 more.How many CDs do you own now? Start with 15 You buy 7 more, which means you add 7 to your total: 15 + 7 = 22

KL=4, and JK=9 Find JL Using segment addition, we know that: JL = JK + KL JL = 9 + 4 JL = 13

Jessie had 8 apples. Katie had 3 more. How many apples does Katie have 3 more means we add to Jessie's total: Katie = Jessie + 3 Katie = 8 + 3 Katie = 11

John had x mangos and p oranges. How many fruits did he have Fruits = mangos + oranges Fruits = x + p

jimmy has 5 apples and beth has 8 apples how many apples do they have together The word together means we add: Total Apples = Jimmy's apples + Beth's apples Total Apples = 5 + 8 Total Apples = 13

If EF = 9x - 17, FG = 17x - 14, and EG = 20x + 17, what is FG? By segment addition, we know that: EF + FG = EG Substituting in our values for the 3 segments, we get: 9x - 17 + 17x - 14 = 20x + 17 Group like terms and simplify: (9 + 17)x + (-17 - 14) = 20x - 17 26x - 31 = 20x - 17 Solve for x...

If EF = 7x , FG = 3x , and EG = 10 , what is EF? By segment addition: EF + FG = EG 7x + 3x = 10 To solve this equation for x, we type it in our search engine and we get: x = 1 Evaluating EF = 7x with x = 1, we get: EF = 7 * 1 EF = 7

A bus usually takes 25 minutes. Because of traffic the trip took 7 minutes longer. How long did the trip take? The word longer means we add, so we have: 25 + 7 = 32 minutes
