To find the number of gallons of a 15% sugar solution needed to mix with a 40% sugar solution to make a 30% sugar solution, set up an equation.
Explanation:In order to solve this problem, we can set up an equation based on the given information.
Let's say we need to mix 'x' gallons of the 15% sugar solution with the 5 gallons of the 40% sugar solution to get a 30% sugar solution.
The equation would be: 0.15x + 0.40(5) = 0.30(x + 5).
Solving this equation will give us the value of 'x', which represents the gallons of the 15% sugar solution needed.

Pip and Sara win some money and share it in the ratio 7:3. Pip gets £36 more than Sara. How much did they get altogether?
Answer:
I think its 90 but im not sure.
Step-by-step explanation:
Final answer:
To find the total amount won by Pip and Sara, a ratio problem was solved by establishing an equation from the given ratio 7:3 and the fact that Pip gets £36 more than Sara, resulting in a total amount of £90.
Explanation:
The question involves solving a problem based on a ratio and determining the total amount of money shared by Pip and Sara. The ratio in which Pip and Sara share the money is 7:3, and since Pip gets £36 more than Sara, we can set up equations to find the individual and total amounts.
Let's denote Sara's share as S, hence Pip's share will be S + £36.
According to the ratio given, Pip's share to Sara's share is 7 to 3, so we can write the equation:
7S = 3(S + 36)
7S = 3S + 108
4S = 108
S = 27
So Pip's share is £27 + £36 = £63.
Adding both shares, the total amount is £63 + £27 = £90.
Therefore, Pip and Sara got £90 altogether.

After decoding the clues on the map, they found out that they needed to go to the
Island of Mysteries which was 120 miles away. To get there, they could either
take a plane for $600 or a boat for $254. How much money can they save if they
took a boat to the island?
Answer:
$346.00
Step-by-step explanation:
We know that the price to take a plane to the Island of Mysteries is $600 and the price to take a boat is $254.
To find how much money they will save if they were to take a boat, you would subtract the cost of the boat ride from the plane ride to find the difference.
$600 - $254 = $346.00

solve for a 7a - 2b =5a + b
Answer:
a = 3/2 b
Step-by-step explanation:
7a - 2b =5a + b
Subtract 5a from each side
7a-5a - 2b =5a-5a + b
2a -2b = b
Add 2b to each side
2a-2b+2b = b+2b
2a = 3b
Divide each side by 2
2a/2 = 3b/2
a = 3/2 b
Solve the system of equations :
2x -5y=-22
X+7y=27
Answer:
x=−1 y=4
Step-by-step explanation:
Let's solve your system by substitution.
2x−5y=−22; x+7y=27
Rewrite equations:
x+7y=27;2x−5y=−22
Step: Solve x+7y=27for x:
x+7y=27
x+7y+−7y=27+−7y(Add -7y to both sides)
x=−7y+27
Step: Substitute−7y+27 for x in 2x−5y=−22:
2x−5y=−22
2(−7y+27)−5y=−22
−19y+54=−22(Simplify both sides of the equation)
−19y+54+−54=−22+−54(Add -54 to both sides)
−19y=−76

(Divide both sides by -19)

Step: Substitute 4 for y in x=−7y+27:
x=−7y+27
x=(−7)(4)+27
x=−1(Simplify both sides of the equation)

The height of a tree increases by 60% each year. When planted the tree was 40cm tall. How tall will the tree be in 5 years time.
Answer:
≈419.4 cm.
Step-by-step explanation:
To solve this problem, you will need to set up an exponential graph as shown:
y= 40 ·[tex](1.6)^{x}[/tex]
The 40 represents the initial height of the tree, while (1.6) represents the annual growth rate. 'x' represents the amount of years elapsed.
We can simply solve this by substituting 5 for x:

Joan receives a 9% commission on appliances she sells. Last month she sold $18,500 worth of appliances. How much did Joan earn in commissions last month?
Answer:
She earned $1,665.
Step-by-step explanation:
x / 18500 = 9/100
What did you do to transform 18500 into 100? Divide by 185
Since you divided the denominator 185, you must do the same to the numerator.
x / 185 = 9 OR 9 * 185 = x
x = 1665
8x-72=2x-36
I need the answer
Answer: [tex]x=6[/tex]
Subtract 2x from both sides
[tex]8x-72-2x=2x-36-2x\\6x-72=-36[/tex]
Add 72 to both sides
[tex]6x-72+72=-36+72\\6x=36[/tex]
Divide both sides by 6
[tex]6x/6=36/6\\x=6[/tex]
Answer:
x=6
Step-by-step explanation:
first thing first you always need to get x alone and since you have an X on both side we need to move one of them to the same side as the other one.
8x-72=2x-36
add 72 on both sides ( the opposite of subtracting is adding)
8x=2x-36+72
8x=2x+36
then we subtract 2x on both sides to get X alone
8x-2x=36
6x=36
then we divide 36 by 6 to get our answer for x
X= 6
and that's your answer, hope this helped

Solve the system. -3x + 4y = -22 2x + 7y = 5 A) (6, -1) B) (-1, 6) C) (-6, 1) D) (-1, -6)
Answer:
A
Step-by-step explanation:
We have the system of equations:
-3x + 4y = -22
2x + 7y = 5
Let's solve this using elimination, so multiply the first equation by 2 and the second equation by 3:
2 * (-3x + 4y = -22) ⇒ -6x + 8y = -44
3 * (2x + 7y = 5) ⇒ 6x + 21y = 15
Our equations are now:
-6x + 8y = -44
6x + 21y = 15
Add these two together to eliminate the x term:
-6x + 8y = -44
+ 6x + 21y = 15
______________
0x + 29y = -29
y = -29/29 = -1
Plug this back into one of the equations to find x:
-3x + 4y = -22
-3x + 4 * (-1) = -22
-3x - 4 = -22
-3x = -18
x = -18/(-3) = 6
The answer is (6, -1) or A.
Answer:
A. (6,-1)
Step-by-step explanation:
-3x + 4y = -22
2x + 7y = 5
x = (5 - 7y)/2
-3[(5 - 7y)/2] + 4y = -22
-15/2 + 21y/2 + 4y = -22
29y/2 = -29/2
y = -1
x = (5 - 7(-1))/2
x = 12/2

The names of nine boys and six girls from your class are put into a hat. What is the probability that the first two names chosen will both be girls?
Final answer:
The probability that the first two names chosen will both be girls from a hat that contains the names of nine boys and six girls is 1/7.
Explanation:
The question involves determining the probability of selecting two girls' names from a hat that contains the names of nine boys and six girls. We are dealing with a situation of probability without replacement, which means that once a name is drawn, it is not put back into the hat.
To calculate the probability of the first name drawn being a girl, we have 6 girls out of the total 15 students, which gives us a probability of 6/15. If a girl's name is drawn first, there will then be 5 girls' names left and 14 names total. So, the probability of the second name drawn being a girl as well is then 5/14.
To find the overall probability of both events happening, we multiply the two probabilities together: (6/15)
x (5/14) = 30/210 = 1/7. Therefore, the probability that the first two names chosen will both be girls is 1/7.
