Ratio of boys to girls is 5:4. We could change that to a fraction, which is 5/4. We now set up a proportion. We will call the unknown number of boys (b): 5/4 = b/60 Solve: (5 x 60)/4 = 300/4 = 75 boys Check: Since a ratio represents division, we can divid...

First of all, no need to panic like that. ;)- Just find the LCD (lowest common denominator) of 8 and 9. That is 72. Convert the fractions to equivalent fractions with a denominator of 72. 7/8 = 63/72 7/9 = 56/72 Now add: 63/72 + 56/72 = 119/72 If you need...

2 inches to 6 feet...we can make a ratio of 2:6. Then simplify to 1:6. The scale is 1 inch on blueprint is 6 feet

Since the probability of getting any color on the spinner is 100%, we can skip that. The probability of getting heads on a coin is 50% so the total probability is 50% Hope this helps!

That last part we can ignore, we can just use the fractions in the first part of the information. 1/3 of 320 cups is 320 x 1/3 = 320/3 = 106 or 107 cups 1/2 of 320 jars is 320 x 1/2 = 320/2 = 160 jars Hope this helps!

Ok, this one we need to know if this is a linear function or solve the variable problem

If it is a linear function, I recommend graphing it here: htt ps://www.desmos.com%2Fcalculator&usg=AOvVaw3Yka4b_Ny7ghvTTOJHdMFZ (Without space)

Wow, I'm guessing you did not pay attention in class huh (no offense) For the sake of conciseness, I will only put answers. 1. v + (v/3 + m) 2. 2y - y/3 3. (x + y)/4 4. L represents the number of people who want large drinks M represents the number of peo...

Ok...so you need explanations instead of answers? Still, I need the table.

If anyone needs help from me please note that my skill level is 8th grade and less.

Awaiting response...

Uh, yeah. You're correct :)

Okay, so just multiply each turtle cared for by 25 (dollars, we don't use units until the end) and add it all up. We could simply put it as: (25 x 4) + (25 x 2) + (25 x 2) + (25 x 2) Using the Distributive Property (tell me if you don't know this property...

And here comes more waiting...

@Jeremy I'm not sure where you got that 4v. Shouldn't that have been 2v?

@Jeremy Look, expression can have variables. Don't know something? Put a variable!

@mathguy Where did you go?

1. (a-24)/3 2. (3 x 15) + (3 x 9) + 7 = 3(15 + 9) + 7 = 3 x 24 + 7 = 84 + 7 = 91 Hope this helps!

Sorry, Anonymous is correct

8 - 5...this is pretty low-level math, so I will explain with a low-level strategy Show 8 fingers on your hands Push down 5 fingers. The answer is 3! Hope this helps!

@Anonymous Probably Middle East or Southwest Asia region.

Oh, well its not 8 - 5, probably an internet brain teaser

No worries, did you see my response, its here: Okay, so just multiply each turtle cared for by 25 (dollars, we don't use units until the end) and add it all up. We could simply put it as: (25 x 4) + (25 x 2) + (25 x 2) + (25 x 2) Using the Distributive Pr...

Hello? mathguy, are you there?

So, do you know what on Earth is the Distributive property?
