Solve the system algebraically. y = 3 -1/2 x 3x + 4y = 1 What is the value of x?

4vir4ik [10]

Answer: $x=-11$

Step-by-step explanation:

You can use the Method of substitution.

Substitute the equation $y=3-\frac{1}{2}x$ into the equation $3x + 4y = 1$ and then you must solve for the variable x:

$3x + 4y = 1\\\\3x + 4(3-\frac{1}{2}x) = 1\\$

Apply Distributive property:

$3x + 12-\frac{4}{2}x = 1\\3x+12-2x=1$

Subtract 12 from both sides of the equation and then add the like terms. Then you get:

$3x+12-2x-12=1-12\\3x-2x=-11\\x=-11$

A boat goes 3/4 hours with a speed of 8 mph and 1/3 hours with a speed of 12 mph. What distance did the boat cover in all this t

Reika [66]

Answer:

10 miles

Step-by-step explanation:

Given: Boat goes $\frac{3}{4}$ hours with 8 mph (i)

Boat goes $\frac{1}{3}$ hours with 12 mph (ii)

Now, lets find out distance separately to get total distance.

Formula for finding distance is

D= $Speed\times time$

D= $\frac{3}{4} \times 8$ (i)

D= $3\times 2$

∴ D1= 6 miles (i)

D= $\frac{1}{3}\times 12$ (ii)

∴D2= 4 miles (ii)

To find total distance, we will add d1 and d2

Total distance = $d1 + d2$

∴ Total distance = $6 + 4$

= 10 miles is the total distance covered by boat in all this time.
