Answer:
80
Step-by-step explanation:
The ratio can be simplified and rewritten:
minutes : miles = 24 : 3 = 8 : 1 = 80 : 10
It will take Josie 80 minutes to run 10 miles at her 8 minutes/mile pace.
Answer:
25
Step-by-step explanation:
To find the missing side (in this case, the longest one/hypotenuse), we can use the equation a^2 + b^2 = c^2. By substituting out the variables, we get 7^2 + 24^2 = c^2; this can be simplified to 49 + 576 = c^2. Add, and then we know that 625 = c^2. If c squared is 625, we need to find the square root of 625, which is 25.
Answer: The answer is (9, -9)
Answer:
14 - 9x + 12 + x
This is an <em>expression </em>(not an equation), therefore it can't be solved.
<u>Factor the expression</u>
Collect like terms:
⇒ 14 + 12 - 9x + x
Combine like terms:
⇒ -8x + 26
Find the highest common factor of 26 and 8
- Factors of 26: 1, 2, 13, 26
- Factors of 8: 1, 2, 4, 8
Therefore, the highest common factor is 2
Factor out -2 from -8x + 26:
⇒ -2(4x + 13)
Alternatively, factor out 2 from 26 - 8x:
⇒ 2(13 - 4x)
48- because you multiply 2 sides together then multiply the other 2 sides then add those together to get 48 so 5x4=20 and 4x7=28 < 28+20=48
