Let the price of paint be x and the price of brush be y
8x + 3y = 152.5 ------------ (1)
6x + 2y = 113 --------------- (2)
(1) x 2 :
16x + 6y =305 -------------(1a)
(2) x (3) :
18x + 6y = 339 -------------(2a)
(2a) - (1a) :
2x = 34
x = 17 ---------- sub into (2)
6(17) + 2y = 113
102 + 2y = 113
2y = 113 - 102
2y = 11
y = 5.5
x = $17, y = $5.50
Each gallon of paint costs $17 and each brush costs $5.50
Step 1
Subtract 26 ft 8 1/6 in from 26 ft 11 1/4 in
(26 ft 11 1/4 in)-(26 ft 8 1/6 in)=11 1/4 in-8 1/16 in
we know that
11 1/4=(11*4+1)/4=45/4
8 1/16=(8*16+1)/16=129/16
so
11 1/4 in-8 1/16 in=(45/4)-(129/16)
=(4*45-129)/16
=51/16 in--------> 3 3/16 in
therefore
<u>the answer is</u>
3 3/16 in
Answer:
Here it is answer do others your self bcz it's easy
The value of the function g(x) = x^3 + 6x^2 + 12x + 8 when x = -1 is 1
<h3>How to evaluate the function?</h3>
The equation of the function is given as:
g(x) = x^3 + 6x^2 + 12x + 8
When x = -1, we have:
g(-1) = (-1)^3 + 6(-1)^2 + 12(-1) + 8
Evaluate the expression
g(-1) = 1
Hence, the value of the function g(x) = x^3 + 6x^2 + 12x + 8 when x = -1 is 1
