Step-by-step explanation:
Answer:
4b + 10c= T
Step-by-step explanation:
Example:
The sum of two consecutive integers is -15. What is the product of the two integers?
x = 1st consecutive integer
x + 1 = 2nd consecutive integer {consecutive integers increase by 1}
x + x + 1 = -15 {the sum of two consecutive integers is -15}
2x + 1 = -15 {combined like terms}
2x = -16 {subtracted 1 from each side}
x = -8 {divided each side by 2}
x + 1 = -7 {substituted -8, in for x, into x + 1}
-8 and -7 are the two consecutive integers
Their product is 56.
Answer:
15
Step-by-step explanation:
The first ratio is 1:3
12/36 = 3
So,
5 x 3 = 15
t - time, d - distance, v - speed
![d=39 \ mi \\ v=26 \ \frac{mi}{h} \\ \\ t=\frac{39}{26}=\frac{3 \times 13}{2 \times 13}=\frac{3}{2}=1.5 \ [h]](https://tex.z-dn.net/?f=d%3D39%20%5C%20mi%20%5C%5C%0Av%3D26%20%5C%20%5Cfrac%7Bmi%7D%7Bh%7D%20%5C%5C%20%5C%5C%0At%3D%5Cfrac%7B39%7D%7B26%7D%3D%5Cfrac%7B3%20%5Ctimes%2013%7D%7B2%20%5Ctimes%2013%7D%3D%5Cfrac%7B3%7D%7B2%7D%3D1.5%20%5C%20%5Bh%5D)
