x/2.4+39=239
show work
Answer: x = 480
Steps: x/2.4 + 39 = 239
Subtract 39 from both sides: x/2.4 + 39 - 39 = 239 - 39
Simplify: x/2.4 = 200
Multiply both sides by 2.4: x/2.4 × 2.4 = 200 × 2.4
Simplify: x = 480

Four students spent $12 on school lunch. At this rate, find the amount 10 students would spend on the same lunch.
Answer:
it's $30 I just know trust meO_o
Step-by-step explanation:
have an amazing day luv
Answer:
10 students would pay for lunch with $30.
Step-by-step explanation:
This is how I know $30 is the correct answer:
1. To figure out how much money it would cost for 1 student I would take the $12 the four students paid for lunch and divide it by 4 so we would know the exact cost for one students lunch (12/4=3 or $3)
2. Now we know $3 is the cost for 1 student. We can now multiply the $3 by 10 (students) so we can get the cost for 10 lunches (3(10)=30 or $30)
3. We got our final answer of $30=10 students lunches.
I hope this helps:)

}−2x+2y=−4
{3x+3y=−18
find the solution to the systems of equations
Answer:
Answer=
x=(-2),y=(-4)
and in components form,
(-2,-4)
Step-by-step explanation:
equation1 (-2x+2y=-4)
equation2 (3x+3y=-18)
(times equation 1 by 3 and times equation 2 by 2, to make the y values equal to each other)
E1 (-6x+6y=-12)
E2 (6x+6y=-36)
(subtract both equations from each other)
-6x+6y=-12
-
6x+6y=-36
=(-12x=24)
so, x=24÷-12=-2
(then we sub the value of x into one of the equations- the new one or the old one)
3x+3y=-18
(3×-2)+3y=-18
3y=-18+6=-12
y=-12÷3=-4
What is the angle relationship?
2 times what equals 84
Answer:
42

Which expression is equivalent to (2g^5)^3
Answer:
Your answer should be 8g^15
Step-by-step explanation:
If cubed (power of 3) is on a parenthesis, that means you have to cube every expression inside that parenthesis. In order to distribute exponents, mutliply them. This gives you g^5 times ^3, which is g^15. ^3 has to also be distributed to the 2, which is 2^3 = 8. 8 and g^15 is 8g^15.

Consider the equation: x^2+10x-24=0 First, use the " completing the square " process to write this equation in the form ( x+D )^2 = E and enter the results below x^2 + 10x -24 = 0is equivalent to......? = ?
Answer:
[tex]x^2 + 10x -24 = 0 \: \\ is \: equivalent \: to \: ( x + 2) {}^{2} + 10x - 36=0[/tex]
Step-by-step explanation:
[tex]x^2 + 10x -24 = 0 \\ x^2 + 12x - 2x -24 = 0 \\x(x + 12) - 2(x + 12) = 0 \\ (x - 2)(x + 12) = 0[/tex]

Brand A coffee sells for $7/pound, while Brand B sells for $5.40/pound. How much of each brand of coffee is needed to make 5 pounds that will cost
$6.75/pound?
A. 0.8 pounds Brand A, 4.2 pounds Brand B
B. 2.7 pounds Brand A. 2.3 pounds Brand B
C. 4.2 pounds Brand A. 0.8 pounds Brand B
D. 2.3 pounds Brand A. 2.7 pounds Brand B
Answer:
C. 4.2 pounds Brand A. 0.8 pounds Brand B
Step-by-step explanation:
How much of each brand of coffee is needed to make 5 pounds that will cost
$6.75/pound?
Let the number of pounds for Brand A = x
Let the number of pounds for Brand B = y
Brand A coffee sells for $7/pound, while Brand B sells for $5.40/pound.
$7 × x + $5.40 × y = $6.75 × 5
7x + 5.40y = 33.75.......Equation 1
x + y = 5 .......Equation 2
x = 5 - y
7(5 - y)+ 5.40y = 33.75
35 - 7y + 5.40y = 33.75
35 - 33.75 = 7y - 5.40y
= 1.25 = 1.6y
y = 1.25/1.6
y = 0.78125 pounds.
Approximately to the nearest whole number, Brand B = 0.8 pounds.
x = 5 - y
x = 5 - 0.8 pounds
x = 4.2 pounds
Brand A = 4.2 pounds

If f(x) = 3x2 + 2x - 2, find f(8) - f(-5)
Answer: 143
Step-by-step explanation:
f(8) = 3(8)^2 + 2*8 - 2 = 3*64 + 16 - 2 = 192 + 16 - 2 = 206
f(-5) = 3(-5)^2 + 2*(-5) - 2 = 3*25 + (-10) -2 = 75 - 10 - 2 = 63
f(8) - f(-5) = 206 - 63 = 143
