Let <span>L </span>be the weight of a large box and S be the weight of a small box.  So we can set up two equations: 2L + 3S = 834L + 8S = 197 Solve for <span>L </span>or S in one of the equations and substitute it into the other equation and find the other unknown. 2L = 83 - 3SL = (83 - 3S)/2 4(83 - 3S)/2 + 8S = 197166 - 6S + 8S = 1972S = 31
S = 15.5 kg<span>
L = (83 - 3(15.5))/2 = 18.25 kg</span>

Set this up as a system of equations.  The first will be the 2 large boxes plus the 3 small boxes weigh 83 kg, the second will be the 4 large boxes plus the 8 small weigh 197 kg.  2L + 3s = 83  and   4L + 8s = 197.  Solve one of them for either variable.  Let's solve the second one for L:  L = -2s + 49.25.  Sub that value of L into the first equation: 2(-2s + 49.25) + 3s = 83.  Distribute through the parenthesis to get -4s + 98.5 + 3s = 83.  Combine like terms to get -s =-15.5.  or s = 15.5.  So a small box weights 15.5 kg.  A large box is -2(15.5) + 49.5, which is 18.5 kg.

Answer:

<u>Answer</u><u>:</u><u> </u><u>(</u><u>0</u><u>,</u><u> </u><u>-</u><u>4</u><u>)</u><u> </u><u>and</u><u> </u><u>(</u><u>6</u><u>,</u><u> </u><u>1</u><u>)</u>

• x(t) = 6t --- equation (a)

• y(t) = 3t - 2 --- equation (b)

→ From equation (a), make t the subject:

→ \: { \tt{x(t) = 6t }} \\  \\ → \: { \tt{t =  \frac{x(t)}{6} }}

• substitute for t in equation (b)

→ \: { \tt{y(t) =  3(\frac{x(t)}{6}) - 2 }} \\  \\ → \: { \tt{y(t) =  \frac{x(t)}{2} - 2 }}

• Assume t is 1:

→ \: { \tt{y =  \frac{x}{2}  - 2}} \\  \\ → \: { \boxed{ \tt{2y = x - 4}}}

• when x is zero, y is -4

→ \: { \tt{2y = 0 - 4 =  - 4}} \\

• when x is 6, y is 1

→ \: { \tt{2y = 6 - 4 = 2 }} \\ { \tt{y = 1}}

Zachary is solving the following equation.
Monica [59]

Answer: C. Distribute 3/4 over (x-8)

Step-by-step explanation:

To solve any(technically most, but still...) algebraic equation you must isolate the variable.  In this case, the first step would either be to divide both sides of the equation by 3/4, or distribute 3/4 to x and -8, as you cannot modify the contents of the parenthesis without removing the 3/4.

Hope it helps and lmk if you further explanation <3 :)

dimulka [17.4K]

Answer:

Vector u has u_x = (5 - 15) = -10, and u_y = -4 - 22 = -26, and its component form would be u = -10i - 26j.

If vector v is in the opposite direction: 10i + 26j

And if it is double in magnitude: v = 20i + 52j

Hope this helps you! Ask me anything if yu have any quistions!
