Answer:
- Keisha is right.
- No, only 1 ratio works
Step-by-step explanation:
- You want the units to be dollars / mango.
- You have 10 dollars. How many mangos can you buy and at what price. They are selling mangoes for more than a dollar each.
- The answer should be $1.25 per mango. Think of it this way:
- If the cost of a mango was $1.00 you would be able to get 10 of them. Do you agree? Since you can only get 8, they must be more than a dollar each.
- The ratio can only be written in one way. 10/8 = 1.25
Answer
- Keisha is right.
- No, only 1 ratio works
12.8-12.4=0.4
0.4 divide by 12.4 = 0.0322
0.0322 x 100 = 3.22%
The answer to your question (“6+(a+b)”) is 8 I’m pretty sure because letters in math equal 1 if there’s no number infront so it’s basically 1+1 and that’s 2 and then u add that two bcuz it was in parentheses to the 6 and it’s 8
A straight path that extends is a line
So we need to isolate the variable. In order to do that, we need to multiply both sides by 5/4.
Why? That's so that 4/5z will be canceled out when multiplied by 5/4 to get just z.
And so, we would get 20 as our answer.
