A man has 25 sweets and his son has 55 sweets.find the number of sweets that the man has to give to his son so that his son would have 4times as many sweets as him.
Answer:
9sweets
Step-by-step explanation:
sweets man has to give to his son=x
mans sweets=25-x
child's sweets=55=x
55+x=4(25-x)
55+x=100-4x
4x+x=100-55
5x=45
x=45/5
x=9
Answer: The man has to give nine sweets for his son to have four times as many sweets as him.
3. The sum of the second term and the ninth term of an arithmetic sequence is -5. The sum of the third and fourth terms of the same sequence is 7. Find the first term of the sequence.
Answer:
First term of the sequence is [tex]11[/tex]
Step-by-step explanation:
Let [tex]a[/tex] be the first term and [tex]d[/tex] be the common difference
We have
The sum of the second term and the ninth term of an arithmetic sequence is [tex]-5[/tex]
[tex]a+(2-1)d+a+(9-1)d=-5\\\\2a+9d=-5---eqn1[/tex]
The sum of the third and fourth terms of the same sequence is [tex]7[/tex]
[tex]a+(3-1)d+a+(4-1)d=7\\\\2a+5d=7---eqn2[/tex]
eqn 1 - eq2
[tex]4d=-12\\\\d=-3[/tex]
Substituting in eqn 1
[tex]2a+9\times -3=-5\\\\2a=22\\\\a=11[/tex]
First term of the sequence is [tex]11[/tex]
Given that f(x) = 10 - 3x and g(x) = x-3/2 find the value of fg(4)
Answer:
-1
Step-by-step explanation:
(fg)(x) is the product of f(x) and g(x).
We can find (fg)(4) by first finding f(4) and g(4) and then multiplying the results together:
f(x) = 10 - 3x, so f(4) = 10 - 3(4) = -2, and
g(x) = x - 3/2, so g(4) = 4 - 3/2 = 1/2
Then (fg)(4) = (-2)(1/2) = -1

One number exceed another by 11, the sum of the two numbers is 5. What are the numbers?
Answer:
The first number is -3, the second number is 8
Step-by-step explanation
Let x = the first number
exceeded means add, so the second number is x+11
sum means add, so the equation is x+x+11=5
combine like terms to get 2x+11=5
subtract 11 on both sides, 2x=-6
divide by 2 on both sides, x= -3
second number was x+11, so -3+11 = 8
What is the product? (x 3)(2 x minus 1) 2 x squared minus 3 2 x squared 6 x 2 x squared 5 x minus 3 2 x squared 6 x minus 3.
The product of the function is 2x^2+ 5x - 3
We are to find the product of the functions x + 3 and 2x -1
let f(x) = x+ 3g(x) = 2x - 1Taking the product:
f(x)g(x) = (x+3)(2x -1)
f(x)g(x) = x(2x) - x(1) + 3(2x) + 3(-1)
f(x)g(x) = 2x^2 - x + 6x - 3
f(x)g(x) = 2x^2+ 5x - 3
Hence the product of the function is 2x^2+ 5x - 3

Find the measure of the missing angle
Please help me, I’ll give you points
Answer:
a = 28°
Step-by-step explanation:
62°+a° = 90°
a = 90 - 62
a = 28°
Answer:
∠A = 28°Step-by-step explanation:
Since we know that 62 + ∠A must equal 90°, we can find the missing angle by isolating the variable.
=> 62 + ∠A = 90°=> ∠A = 90 - 62=> ∠A = 28°Conclusion:
Therefore, the measure of the missing angle is 28°.

Answer:
42 cm is the perimeter
Step-by-step explanation:
Brainleast answer mo nalang
Answer:
P = 42 cm
Step-by-step explanation:
The perimeter (P) is the sum of the 4 sides of the rectangle with opposite sides being congruent.
Given width = 7 cm then length = 2 × 7 = 14
P = 7 + 7 + 14 + 14 = 42 cm

Answer:
One solution
Step-by-step explanation:
Start by simplifying the equation.
Distribute 3 to 4 and 2 to get 12x + 6Combine 8x and -2x to get 6xThen you have 12x + 6 = 6x + 24,
Continue to solve
Subtract 6 from the left and right to get 12x = 6x + 18Subtract 6x from both sides to get 6x = 18Divide both sides by 6 to get x = 18Because x is equal to one digit and not x = x or 3 = 5, you have one solution

The table shows the prices for fruit items at a local farmer’s market. Katelyn purchased four pounds of apples, six navel oranges, two mangoes, and three watermelons. The farmer’s market charged a convenience fee of $3 per order. Katelyn paid with a $50 bill.
Fruit Price List
Item Price
Crispy Apples $1.79 (per pound)
Navel Oranges 4 for $5.00
Mango $1.50 each
Watermelon $5.99 each
How much change should Katelyn receive from the $50 bill?
F.$11.37
The change Katelyn should receive from the $50 bill is $11.37.
The first step is to determine the total cost of the purchase.
Total cost of the 4 pounds of apples = $1.79 x 4 = $7.16
Total cost of six navel oranges = ($5 / 4) x 6 = $7.50
Total cost of two mangoes = $1.50 x 2 = $3
Total cost of three watermelons = $5.99 x 3 = $17.97
Total cost of the fruits = $35.63
Total cost of the order = $35.63 + $3 = $38.63
Change = $50 - $38.63 = $11.37

The swimming team has competed in 45 races this season. They have won 30 races so far. How many races will the team need to win today for the team to have a 75% success rate? 8 10 12 15.
The number of races the team need to win today for the team to have a 75% success rate is 15
Number of attempt = 45
Number of winnings = 30
Percentage won so far = 30/45 × 100
= 66.67%
let
x = Number of races that tfe team needs to win to have 75% success rate
(30 + x) / (45 + x) = 0.75
Cross product
30 + x = 0.75(45 + x)
30 + x = 33.75 + 0.75x
x - 0.75x = 33.75 - 30
0.25x = 3.75
x = 3.75 / 0.25
x = 15
Therefore, the number of races the team need to win today for the team to have a 75% success rate is 15
