Jhahad you seem to have trouble writing the equation. It's like translating to another language. If x is the first of three consecutive odd integers, then (x+2) is the second number and (x+4)is the third one. Let's translate the sentence step by step. Twice the...

Hi Devora, I would like to explain combining like terms to you. The expression 3a+4b-3a-b has four terms: 3a, 4b, -3a, and -b. Like terms are the one s with common variable parts: 3a and -3a are like terms, 4b and -b are also like terms. To...

I like Jonathan explanation. Here is different approach to solution. In 12 hours Igor can make 1 ball and Bill can make 12÷4=3 balls. Together they can make 1+3=4 balls in 12 hours. It takes them 12÷4=3 hours to make 1 ball. Best Wishes

When you solve expression with exponents, make sure you follow order of operations. I your problem multiplication written first but squaring should be calculated first because power has a priority in order of operations. 8×42=8×16=128

Hi Alvis. Ethan gave you the great explanation for understanding but I want to give you algebraic one. You can rewrite the expression as 1×x +3×x. Now it looks like formula for distributive proprety a×c - b×c=(a - b)×c By applying distributive proprety you will get (1 +...

Hi Bonnie, You can rewrite the expression as 1×p - 0.15×p. Now it looks like formula for distributive proprety a×c-b×c=(a-b)×c By applying distributive proprety you will get (1 - 0.15)×p=0.85×p=0.85p If you noticed: the coefitient in your answer is the difference of...

Hi Jasmine, Solving quadratic equation is a big part of Algebra 1 course. One of the methods is to use Zero Product Property: if a product equal zero then one of the factors should be equal zero. It means that if a×b=0 then a=0 or b=0. In order to use Zero...

The Tortoise approach the Hare with rate (50-.25) ft/sec. The distanse between them is 1,000 ft. According to D=R×T formula T=D/R=1,000/(50-.25) sec

You can try guess-and-check approach. The problem says that "Large dogs were the smallest number of animals". Pick a small number (3 for example) for a number of large dogs. Use other pieses of information to find number of cats, medium dogs and small dogs. Then find the lodgin cost...

If we assume that treats are divided equally among containers then Allison packed 24÷4=6 treats in each container and Hansen packed 20÷4=5 treats in each container. Therefore Allison packed 6-5=1 more treat in each container than Hansen.
