= 2x² - 4x - 3x + 6
= 2x² - 7x + 6
At a football game, a vender sold a combined total of 117 sodas and hot dogs. The number of sodas sold was two times the number of hotdogs sold.find the number of sodas and the number of hotdogs sold
Answer:
Sodas(s) + Hot Dogs (d) =117
d =2s
s+2s = 117
3s = 117
s= 117÷3
s= 39 sodas
Hot Dogs =2s = 2x39 = 78

Step-by-step explanation:
2(7x + 13) - 16x = 3(x + 11) - 4x
Answer:
One Solution
x= -7
Step-by-step explanation:
2 times 7x is 14x
2 times 13 is 26
3 times x is 3x
3 times 11 is 33
Now the equation looks like this:
14x+26-16x=3x+33-4x
Now Simplify:
-2x+26=-x+33
Add x on both sides and subtract 26 on both sides:
-x=7
Divide by -1 on both sides:
x=-7
So one solution and the one solution is -7

She measure the length of the trees shadow ( on the ground) which was 42 meters. Then she positioned the ladder. Which was 2.4 meters high, and measured its shadow. The ladders shadow ( on the ground) was exactly 3 meters
Answer:
The tree was 33.6 meters tall.
Step-by-step explanation:
So the question is "How tall is the tree?" I take it.
tree height/shadow length = ladder height / shadow length
Notice that the heights are both in the numerator. A proportion should always do this. It should have the same units on either the two denominators or the 2 numerators.
x / 42 = 2.4 / 3 Multiply both sides by 42
x = 42 * 2.4 / 3
x = 100.8 / 3
x = 33.6
Answer:
33.6
Step-by-step explanation:
x/42 = 2.4/3
x = 2.4/3 x 42
x = 2.4/1 x 14
x = 33.6/1
x = 33.6
Find the 52nd term of the arithmetic sequence -8 -12 -16
Answer:
a₅₂ = - 212
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 8 and d = a₂ - a₁ = - 12 - (- 8) = - 12 + 8 = - 4 , then
a₅₂ = - 8 + (51 × - 4) = - 8 - 204 = - 212
what is the solution set to this inequality:6x-20>3(2-x)+6x-2
Answer:
x>8
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
6*x-20-(3*(2-x)+6*x-2)>0
6x - 20) - ((3 • (2 - x) + 6x) - 2) > 0
3x - 24 = 3 • (x - 8)
3 • (x - 8) > 0
x > 8

here is a easy question :- if -25/5 x p/q =1 , then p/q is equal to ?
9514 1404 393
Answer:
-1/5
Step-by-step explanation:
Divide by the coefficient of p/q:
-25/5 × p/q / (-25/5) = 1 / (-25/5)
p/q = -5/25
p/q = -1/5 . . . . in reduced form

2x + 5 = 3 + 2(x + 1). Which choice describes the meaning of her result, 5 = 5?
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. Start by using the distributive property with 2(x+1) --> 2x+2
2. Your equation will be 2x + 5 = 3 + 2x + 2
3. Add the 3 and the two on the left side to be 5 + 2x
4. Your equation will be 2x + 5 = 5 + 2x
5. Now minus 2x from both sides so the 2x will cancel out
6. 5 = 5

math question 13 - 4x = 1 - x
Answer: x = 4
Step-by-step explanation:
To solve this problem, make use of the fact that you may add anything to an equation, as long as you do it to both sides.
Simply add 4x to both sides to get:
13 = 1 + 3x
Then simply add -1 to both sides to get:
12 = 3x
Then, divide both sides by 3 to get:
4 = x
Hope it helps :) and let me know if you want me to elaborate.

What should be the percentage gain on a product when it is sold for Rs.250 with a
gain of Rs.50.
Answer:
Sp = ₹250
Gain = ₹50
CP = SP - Gain
CP = ₹(250 - 50)
CP = ₹ 200
Gain = ₹50
Gain% = [tex]\frac{Gain}{CP}[/tex] × 100
= [tex]\frac{50}{200}[/tex] × 100
Gain% = 25%
Hope it will help you.

Javier says that when you add a positive and a negative number the sum is always negative. Is javier statement true or false? explain your reasoning
Step-by-step explanation:
False
If the positive number is greater than the negative, then it will stay positive.
say the question is 5+ -3.
The answer would be 2
Answer:
False
Step-by-step explanation:
It depends on what sign the larger number is. For example, -5+9= 4 because they are opposite signs and 9 is the larger number of the two, therefore the answer is a positive 4.

a $2400 deposit for 8 years compounded at annual interest rate of 4.5% what is the interest and the total value
Answer:
$3,619.09
Step-by-step explanation:
liam deposits $2400 into an account that earns 8.3% interest compounded quarterly.
Compound interest formula is
where A is the final amount
P is the initial amount deposited
r is the rate of interest
n is the compounding period
t is the time in years
P= 2400, r= 8.3%= 0.083, t=5, n=4 (quarterly)
Plug in all the values
A= 3619.09
I need answer for this quick please
Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 1, 4 ] , then
f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36
f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then
average rate of change = [tex]\frac{-36-(-6)}{4-(-1)}[/tex] = [tex]\frac{-36+6}{4+1}[/tex] = [tex]\frac{-30}{5}[/tex] = - 6
