Step-by-step explanation:
i believe what you need help on is simplifying the equations. so let's start with the first one.
====================================================================
(2x+1)(x+5) original problem
(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.
2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.
2x2+11x+5 this is the most simplified equation.
====================================================================
6x−4xy original problem.
unlike the last problem, we can easily just... 6x + (−4xy).
−4xy+6x this is the most simplified equation.
====================================================================
ok, the last one. phew!
unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.
if we factored, we would get...
(4x+5)(4x−5)
===================================================================
hope this helps! :>

At the movies, you order 3 boxes of popcorn and a bottle of water. The cost of the bottle of water is $1.75. Your total cost is $9.25. Write an EQUATION to find the cost of one box of popcorn.
Answer:
Step-by-step explanation:
$9.25-$1.75=7.5
now you divide 7.5 by the number of popcorn have brought
$7.5 divided by 3= $2.5
Jenny is comparing the cost of two packages of socks. 1 package has eight pairs of socks for $12. Another package has 3 pairs of socks for $6. Are the rates equivalent?
Answer:
No, they are not equal rates.
Step-by-step explanation:
Package 1:
8 pairs : $12
8 ÷ 12 ≈ $0.67
Package 2:
3 pairs : $6
3 ÷ 6 = $0.6
Comparing...
$0.6 ≠ $0.67
Gerard is calculating the area of a composite figure. The figure is made up of a square with side lengths of 6 centimeters (cm) and a triangle with a base of 6 cm and a height of 3.5 cm.
Gerard multiplies 6 by 3.5 to get that the area of the figure is 21 cm2, which is not the correct area.
Which statement correctly describes how Gerard could have found the correct answer?
-He should have found the area of the square, 36 cm2, and added it to the area of the triangle, 27 cm2, to get 63 sq. cm.
-He should have added 6 to 3.5 to get 9.5 sq. cm.
-He should have multiplied 21 by 12 to get 10.5 sq. cm.
-He should have found the area of the square, 36 cm2, and added it to the area of the triangle, 10.5 cm2, to get 46.5 sq. cm.
HELP PLEASE
The correct statement is Gerard should have found the area of the square, 36 cm², and added it to the area of the triangle, 10.5 cm², to get 46.5 sq. cm.
What is Area?Area of a geometrical shape or figure in two dimension is the space which lies within the boundary of the shape.
The given composite figure composed of a triangle and a square.
So, we should find the area of both the triangle and the square and add it to get the area of the composite figure.
Let A₁ and A₂ be the area of the square and area of the triangle respectively.
Area of a square with side lengths 'a' = a²
Here, length of the side of the square = 6 cm
A₁ = 6² = 36 cm²
Area of a triangle with base 'b' and height 'h' = [tex]\frac{1}{2}[/tex] × b × h
Here, b = 6 cm and h = 3.5 cm
A₂ = [tex]\frac{1}{2}[/tex] × 6 × 3.5 = 10.5 cm²
Area of the composite figure = A₁ + A₂
= 36 cm² + 10.5 cm²
= 46.5 cm²
Hence Gerard could have found the correct answer by finding the area of the square as 36 cm², and adding it to the area of the triangle, 10.5 cm², to get the area of the figure as 46.5 cm².

10 POINTS: Last week, Belle's Diner sold 8 milkshakes with whipped cream on top and 24 milkshakes without whipped cream. What percentage of the milkshakes had whipped cream?
10 points if solve, will give brainliest to the correct answer. please explain I really need help with solving percentages, ( Thanks SO MUCH!)
* THANKS!*
Answer:
25% of the milkshakes had whipped cream.
Step-by-step explanation:
Belle's Diner sold 8 milkshakes with whipped cream and 24 milkshakes without whipped cream. Given this information, we can add these two numbers to identify the total number of milkshakes Belle's Diner made:
[tex]8+24=32[/tex]
Belle's Diner made 32 milkshakes in total.
To find the percentage of milkshakes that had whipped cream, simply divide the number of milkshakes that had whipped cream (8) by the total number of milkshakes (32):
[tex]\frac{8}{32} =.25[/tex]
.25 as a percentage is 25% (move the decimal point two decimal places to the right).
Answer:
25% of the milkshakes have whipped cream on top.
Step-by-step explanation:
24+8=32
8/32=.25
*Note: To get the decimal form of any fraction you divide the numerator by the denominator.
.25 = 25%

Angle B and angle C are supplementary. If the measure of angle B is 14 times the measure of angle C, what is the difference between the angles' measures?
Enter your answer as the correct number of degrees, like this: 42
HELP PLEASEEEEEE
Answer:
156°Step 1: Create an Equation Using the idea (Angle B + Angle C = 180°)
=> 14x + x = 180°
Step 2: Solve.
=> 14x + x = 180°
=> 15x = 180°
=> x = 12°
Step 3: Multiply 12 by 14.
=> 12 x 14 = 168°
Step 4: Subtract 168 by 12.
=> 168 - 12
=> 156°
Final Answer:
After working on this problem, we can conclude that the difference between Angle B and Angle C is 156°

Answer:
D. Henry's balloon was further from town at the beginning, but Tash's balloon traveled more quickly.
Step-by-step explanation:
With the lack of information provided, I was able to create a base and general observation and create an equation based off everything I know and believe. (may not be accurate due to lack of information and background on assignment and curriculum)
TASHA: y = 7x + 15
(current distance) = (7 miles per hour) + (starting distance)
(29) = (14) + (15)
HENDRY: y = 6x + 25
(current distance = (6 miles per hour ) + (starting distance)
(37) = (12) + (25)
Find the value of x in the following diagrams (I drew them instead)
Answer:
1) 51° 2) _?_ 3) 55 ⁰ 4) 30°
Step-by-step explanation:
3) First you find out what is G which = 90⁰, And then add the 90 and 75.
Then we will make this equation : (90+75) - 360 ( because Angle Sum property = Sum of all angles from the inside = 360⁰)
Then we do that which will be = 185-360
= 175
The we plus all the x's = x + 2x
= 3x
then our equation is = 3x= 175
x = 175/3 (Because of Transposition )
x= 55°
And Then we do add and multiply
Like This: x=55
2x= 2x55 = 110°
1) First add 67 and 62
Then our equation= (67+62)-180 ( Because of Interior angle sum property of triangles = sum of all interior angles = 180°)
Then = 129 - 180
= 51 °
And then because of opposite angle are equal so our x= 51° because our angle in the triangle above x = 51° so it will be equal opposite (hope you understand)
4) First add 2x+4x
Our Equation= (2x+4x)=90° (be cause right angle = 90°)
= 6x=90
x =90/6
x = 15°
So, 2x= 2 x 15 = 30°
4x = 4 x 15 = 60°
2) Sorry I don't know the second one but i tried solving it but one favor can you please make another question for the second one in brainly so i can answer there.
