A bag contains purple marbles and white marbles, 68 in total. The number of purple marbles is 4 less than 5 times the number of

galina1969 [7]

Answer: 56 purple marbles.

Step-by-step explanation:

Let be "p" the number of purple marbles in the bag and "w" the number of white marbles in the bag.

You can set up the following System of equations:

$\left \{ {{p+w=68} \atop {p=5w-4}} \right.$

You can use the Substitution method to solve the System of equations. The steps are shown below:

1. You need to substitute the second equation into the first equation:

$(5w-4)+w=68$

2. Now you must solve for "w":

$5w-4+w=68\\\\6w-4=68\\\\6w=68+4\\\\6w=72\\\\w=\frac{72}{6}\\\\w=12$

3. Substitute the value of "w" into second original equation and then evaluate in order to find the value "p":

$p=5(12)-4\\\\p=60-4\\\\p=56$

Question: F=d+e+t, solve for t.

Komok [63]

F = d + e + t Flip the sides to put t on the left
d + e + t = F Subtract d from both sides
e + t = F - d Subtract e from both sides
t = F - d - e

D. y = 3x + 2

Check (-4, -10)
-10 = 3(-4) + 2
-10 = -12 + 2
-10 = -10 :)

Check (-3, -7)
-7 = 3(-3) + 2
-7 = -9 + 2
-7 = -7 :)

Check (-2, -4)
-4 = 3(-2) + 2
-4 = -6 + 2
-4 = -4 :)

Check (-1, -1)
-1 = 3(-1) + 2
-1 = -3 + 2
-1 = -1 :)

Check (0, 2)
2 = 3(0) + 2
2 = 0 + 2
2 = 2 :)
