Step-by-step explanation:
-1 + 4 (6x + 3) = 1/2 (-10x - 10) -5
Answer: x = 60/11
Step-by-step explanation:
-1 + 4 (6x + 3) = 1/2 (-10x - 10) -5
Multiply the 1/2 with -10x, and -10.
Let's look on the side that we are working on now.
New equation:
- 1 + 4 (6x + 3) = -5x - 5 - 5
-5-5= -10
-1+4(6x+3)=-10-5x
Next we remove the brackets.
-1 + 4 * 6x + 3 = -10x -5
Now we bring the x's on one side and the non-x's on the other. When we bring a positive x on the other side of an equal sign, it becomes negative. If we bring a negative x on the other side of an equal sign, it becomes positive.
10x * 6x = 1 - 4 - 3 - 5
60x = 1 - 12
60x = -11
x = 60/11

Jane and her friends are going on a hiking trip. Jane wants to make snack packs to take on a trip. She has 24 apples and 36 small bags of trail mix. Each snack pack must have the same number of apples and the same number of bags of trail mix. What is the greatest number of snack packs Jane can make? Explain.
Answer:
The greatest number of snack packs Jane can make is 12 snack packs
Step-by-step explanation:
We solve this question using the greatest common factor method
First step would be to find the factors of 24 and 36
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
Then the greatest common factor amongst the above factors for 24 and 36 is 12.
Therefore, the greatest number of snack packs that she can make is 12 packs.

A magic carpet is made with three colors of yarn. The ratio of each color in the carpet is shown below: 10 parts gold yarn 7 parts bronze yarn 3 parts silver yarn The magic carpet is made with a total of 150 meters of yarn. How much silver yarn is in the magic carpet?
Answer:
There are 22.5 meters of silver yarn
Step-by-step explanation:
Gold yarn : bronze yarn : silver yarn
10 : 7 : 3
Gold yarn = 10
bronze yarn = 7
silver yarn = 3
Total ratio = 20
Total meters = 150 meters
How much silver yarn is in the magic carpet?
Quantity of silver yarn in the carpet = silver yarn ratio / Total ratio × total meters of yarn
= 3 / 20 × 150
= 450 / 20
= 22.5 meters
There are 22.5 meters of silver yarn
Bronze yarn = bronze yarn ratio / Total ratio × total meters of yarn
= 7 / 20 × 150
= 1,050 / 20
= 52.5 meters
Bronze yarn = 52.5 meters
Quantity of gold yarn in the carpet = gold yarn ratio / Total ratio × total meters of yarn
= 10 / 20 × 150
= 1500 / 20
= 75 meters
Gold yarn = 75 meters

10 Brynlee's monthly cell phone bill
is $60 a month plus $2.50 per
gigabyte used. Raylin's cell phone bill is $450
per month plus $3.25 per gigabyte used.
Determine after how many gigabytes used
would the cell phone plans cost the same
for the month what is the answer??
Answer:
20 gigabytes
Step-by-step explanation:
Let n represent the amount of gigabytes used.
First make an equation for each senario, Brynlee's would be 60+2.50n and Raylin's would be 45+3.25n.
Set them to equal each other, 60+2.50n=45+3.25n.
Then isolate for n.
60-45=3.25n-2.50n
15=0.75n
Divide both sides by 0.75 to get 20
If the height of an equilateral triangle ABC is 5/ 3 cm. Let us write by calculating the area
of this triangle
• Height of the equilateral triangle = 5/3 cm .
To find :• The area of the triangle .
Solution:• First find side :
As we know that:
• Height = √3/2 (side)
=> 5/3= √3/2 (side)
=> side = 10/3√3 cm
• Area of equilateral triangle = √3/4 (side)².
=> Area = √3/4(10/3√3)²
=> Area = √3/4(100/27)
=> Area = 25√3/27
=> Area = 43.30/27
=> Area = 1.60 cm².
Hence, the area of equilateral triangle is 1.60cm²

Answer:
x=-10
Step-by-step explanation:
15-2(x+5)=25
multiply the 2 by the x and 5 and you get
15-2x-10=25
since the 15 and the negative 10 are on the same side you add them together and get
5 -2x= 25
-5 -5
-2x =20
Then divide the -2/20= -10
Answer:
x = -10
Explanation:
15 - 2 ( x + 5 ) = 25
Distribute 2 through the parentheses
15 - 2x - 10 = 25
Subtract the numbers
5 - 2x = 25
Move constant to the right-hand side and change its sign
-2x = 25 - 5
Subtract the numbers
-2x = 20
Subtract both sides
x = -10

At a local pizza shop, large pizzas cost $14.50 and small pizzas cost $9.00. On Thursday, the number of large pizzas sold was 3 less than twice the number of small pizzas sold. The total value of all pizzas sold was $640.50. How many of each type of pizza did the pizza shop sell?
Answer:
Small pizzas = 21
Large pizzas = 39
Step-by-step explanation:
The number of small pizzas sold be x
So, the number of large pizzas sold be 2x - 3
And the total value is $640.504
Now the equation would be
$14.50x + $9 × (2x - 3) = $640.50
$14.50x + 18x - $27 = $640.50
$32.50 = $640.50 + $27
$32.50x = $667.50
x = 21
Now the large pizzas is
= 2 × 21 - 3
= 39

The points A, B, and C lie on a line so that AB = 12 cm and BC = 13.5 cm. Find the length of segment AC. Give all possible answers.
Give two possible answers. Not just one please.
Answer:
25.5 and 1.5
Step-by-step explanation:
AC = 12 cm
BC = 13.5 cm
12 + 13.5 = 25.5 cm
13.5 - 12 = 1.5 cm
The possible length of segment AC is 25.5 cm and 1.5 cm.
What is a line segment?A line segment is a part of line that is bounded by two distinct end-points. A line segment has a fixed length. Figures such as a triangle, polygon, hexagon, square are made of different numbers of line segments.
For the given situation,
The points A, B, and C lie on a line.
Length AB = 12 cm
BC = 13.5 cm
The possible length of segment AC can be found by adding and subtracting the lengths of AB and BC.
a) Length of AC = [tex]13.5+12[/tex]
⇒ [tex]25.5[/tex] cm
b) Length of AC = [tex]13.5-12[/tex]
⇒ [tex]1.5[/tex] cm
Hence we can conclude that the possible length of segment AC is 25.5 cm and 1.5 cm.
