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
