Answer: a = 6
Step-by-step explanation:
2a - 8a = 12 - 8a
Add 8a to each side
10a - 8a = 12
Subtract 10a and 8a
2a = 12
Divide each side by 2
a = 6
The value of x - coordinate is 14.4
<em><u>Solution:</u></em>
Given that we have to find the x -coordinate of the system
<em><u>Given system of equations are:</u></em>
2x + 3y = 144 -------- eqn 1
y - x = 24 --------- eqn 2
Solve the above system of equations to find the x - coordinate
From eqn 2,
y = 24 + x ------- eqn 3
Substitute eqn 3 in eqn 1
2x + 3(24 + x) = 144
2x + 72 + 3x = 144
Add the like terms
5x + 72 = 144
5x = 144 - 72
5x = 72
Divide 72 by 5
x = 14.4
Thus the x - coordinate of the system is 14.4
Not sure what you mean by solve for r^2
but
a/4=r^2
if u wanna go further
r=(a/4)^1/2
Answer:
A) 4
-4
-16
+16x
B)4-4-16+16x
Step-by-step explanation:
look at picture
Given:
95 pink rubber bands
90 brown rubber bands
185 rubber bands in all.
Probability of pink : 95/185 ⇒ 19/37
95 ÷ 5 = 19
185 ÷ 5 = 37
Probability of brown : 90/185 ⇒ 18/37
90 ÷ 5 = 18
185 ÷ 5 = 37
