Step-by-step explanation:
"The total number of dollars in fives and tens" tells you that these denominations are being added together. Because a five dollar bill is worth $5 and a ten dollar bill is worth $10, then the number of $5 bills is represented by 5f and a the number of $10 bills is represented by 10t. Therefore,
T = 5f + 10t

D
Step-by-step explanation:
![( {2 x})^{ \frac{1}{3} } - 7 = \sqrt[3]{2x} - 7](https://tex.z-dn.net/?f=%28%20%7B2%20x%7D%29%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%20-%207%20%3D%20%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%207)
Cut 5/12 of his lenght
remain 7/12 of his lenght
7/12*L - 6/7 *7/12*L=2 1/2 m
7/12*L(1-6/7)=7/12*L(7/7-6/7)=7/12*L*1/7=L/12 =2 1/2
⇒L=2 1/2 m *12=5/2*12=30 m
Original length was 30 m

Step-by-step explanation:
To write an equation in standard form, move each term to the left side of the equation and simplify.
a x 2 + b x + c = 0
Move 3 to the left side of the equation by subtracting it from both sides.
x 2 + 6 x + 8 − 3 = 0
Subtract 3 from 8
. x 2 + 6 x + 5 = 0
