Answer:
7.5 gallons
Step-by-step explanation:
2.5/5+x=0.2
This question is based on the concept of solving an equation. Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.
Given:
5 gallons of 50% acid solution to get a 20% solution.
According to question,
Let it be x gallons of water should be added to 5 gallons of 50% acid solution to get a 20% solution.
Now, forming the equation, we get,
0.50 ( 5 ) = 0.20 ( x + 5 )
Simplifying the equation.
We get,
2.5 = 0.2x + 1
1.5 = 0.2 x
x = 7.5
Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

Answer:
24x - 16
Step-by-step explanation
What we're doing here is factorisation
To factorise a number, you need to multiply the number outside of the bracket (in this case -4) by both of the inside numbers (-6x and 4).
First,
-4 x -6x
-4 x -6x = 24 , The x also needs to be kept- coming from the -6x, so the answer would be 24x.
You may think that because there are minuses involved, the answer would be -24x but you need to remember the rule that 2 negatives make a positive!
Next,
Multipying the outside number by the second inside again:
-4 x 4 = -16
Alongside the rule that two negatives make a postive, another rule is that one negative and one positive always result in a negative.
Finally,
Connect both of these answers
24x - 16 is the answer!
(The minus/negative symbol in the final answer is because the second multipication turned out negative, if the second number was positive, the answer would be 24x + 16.)

Im doing this till 3:30
Answer: C
Step-by-step explanation:
First set greater than 300 since Zack has to make more than 300 to make a profit. The equation is the amount he makes (n) - cost of supplies ($32.50). He is completing 4 rooms so multiply (n - 32.5) with 4.
The equation would be 4 (n - 32.5)>300
Now to solve for n, divide 4 on other sides, then add 32.5 to both sides.

Answer:
[tex]a_n=-8+(n-1)-7[/tex]
Step-by-step explanation:
General arithmetic sequence formula: [tex]a_n=a_1+(n-1)d[/tex]
where [tex]a_1[/tex] = first term, and d = common difference.
The first term is -8
And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.
To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula
General formula: [tex]a_n=a_1+(n-1)d[/tex]
We have [tex]a_1=-8[/tex] and d = -7
So the formula to find the nth term would be
[tex]a_n=-8+(n-1)-7[/tex]

141x + 50 + 4x = 340
What is x?
Answer:
x = 2
Step-by-step explanation:
141x + 50 + 4x = 340
=> 145x + 50 = 340
=> 145x = 290
=> x = 2
Hoped this helped.
Simplify both sides of the equation
141x+50+4x=340(141x+4x)+(50)=340(Combine Like Terms)145x+50=340145x+50=340Subtract 50 from both sides
145x+50−50=340−50145x=290Divide both sides by 145
[tex] = > \frac{145x}{145} = \frac{290}{145} [/tex]

The family likes peaches and other fruits. The local farmer’s market is selling fresh peaches at a discounted price. If the farmer’s market sold 35% of its produce and has 280 peaches remaining, how many peaches did it originally have on hand? Show all your work and explain how you used equivalent ratios to solve the problem. (2 points)
Answer:
Sorry for the super late answer but here:
Step-by-step explanation:
If it sold 35% and now there is 280 remaining, that means that they produce 280 x 135%. That is also equal to 280 x 1.35. The equation is equal to 378 remaining. Please give me brainiest if you see this. However, it is ok if not since this is a super late answer plus I didn't use equivalent ratios.

Sarah wanted to buy a TV. She had $390 in her pocket. The TV she wanted was $415; however she had a 10% off coupon. The sales tax is 6%. Does she have enough money to purchase the TV?
Answer: Sarah does not have enough money to purchase the TV.
Explanation: The total price is $395.91.
Answer:
No
Step-by-step explanation:
10% of 415
= 1/10 of 415
= 1/10 * 415
= $41.5
415 - 41.5 = $ 373.5
6% of 415
= 6% * 415
= $24.9
∴ $373.5 + $24.9 = $398.4
∴ Sarah cannot buy the TV as she is $ 8.4 short.
