Answer:106
Step-by-step explanation:
Let number of white marbles be w
Let number of red marbles be r
w+r = 126---------1
w = 6 +5r-----------2
Put eqn 2 in eqn 1
6+ 5r + r = 126
6 + 6r = 126
6r = 120
r = 20
w = 6 +5r =6+100
= 106
Answer:
-399.5
Step-by-step explanation:
You divide, add, then subtract.
Answer:
A = -10
Step-by-step explanation:
x^2 + 10x + 24 = 0
To find the roots, we need to factor the equation.
What 2 numbers multiply to 24 and add to 10
6*4 = 24
6+4 = 10
(x+6) (x+4)=0
Using the zero product property
x+6 = 0 x+4 = 0
x = -6 x = -4
We want the sum when the roots are added
-6+ -4 = -10
<h3>
Answer: 0.05x+10</h3>
Work Shown:
x = number of miles
Cost of company A = 0.09x+50.50
Cost of company B = 0.14x+60.50
Subtract the two expressions (B-A) to find the difference in price
B-A = (0.14x+60.50)-(0.09x+50.50)
B-A = 0.14x+60.50-0.09x-50.50
B-A = (0.14x-0.09x) + (60.50-50.50)
B-A = 0.05x+10
Answer:
x = 18.64
Step-by-step explanation:
use tan:
⇒ tan = 
⇒ tan 46 = 
tan of 46 is 1.0355
⇒ 1.0356 =
multiply 18 on both sides
⇒ 1.0355 x 18 = x 18
⇒ 18.64 = x
