Answers
x = 3
Step-by-step explanation:
AB = CB
8x + 5 = 10x - 1
8x - 10x = -1 - 5

Answers
1.) -6x + y = 4
Move variable x over to the other side by adding 6x.
y = 6x + 4
2.) -y - 2x = 4
Move variable x over to the other side by adding 2x.
-y = 2x + 4
Divide the whole thing by -1 because y needs to be positive and alone.
y = -2x - 4

In a bag there are blue sweets, red sweets and yellow sweets. The number of blue sweets is four times the number of yellow sweets. The number of red sweets is half the number of yellow sweets. Find the percentage of sweets in the bag that are yellow.
Answers
Answer:
18.18%
Step-by-step explanation:
The percentage of sweets in the bag that are yellow is as follows:
Let us assume the number of yellow sweets be x
So for number of blue sweets be 4x
And, the number of red sweets be 0.5x
So it could be written as
Blue Red Yellow
4 0.5 1
8 1 2
So for yellow, the percentage is
= 2 ÷ (8 + 1 + 2)
= 2 ÷ 11
= 18.18%

Answers
Answer:A
Step-by-step explanation:
Interior angles of a triangle ALWAYS have to be equal to 180
The sum of A is 180, however, those angles wont work because they have to be more close to eachother for it to be possible
The Triangle Inequality Theorem states the longest side must be shorter than the sum of the other 2 sides

Answer:
because 3 spheres is inside the cylinder and they are placed close together
=> The height of the cylinder is 3 times the diameter
=> the height is 18cm
the volume of the cylinder is 3,14.18.(6/2)² = 508,68
because 3 spheres have the same diameter
=> the volume of 3 spheres is 4.3,14.3³ = 339,12
=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56
Step-by-step explanation:
Answer:
The answer is 508,68
Step-by-step explanation:
Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height
Since the radius of the base is equal to 3 and since the area of its cylinder is equal to
[tex]314 \times 3 \times 3 = 28.26[/tex]
When the height equal to 18
Then the volume equal to
[tex]28.26 \times 18 = 508.68[/tex]

Mathilde has 20 pints of green paint. She uses 2/5 of it to paint a landscape and 3 /10 of it while painting a clover. She decides that, for her next painting, she will need 14 pints of green paint. How much more paint will she need to buy?
Answers
Answer:
8
Step-by-step explanation:
Total pints of paint = 20
For landscape :
2/5 * 20 = 8 pints
For clover :
3/10 * 20 = 6 pints
Total used = (8 + 6) = 14
Pints left = 20 - 14 = 6 pints
14 required for next painting
14 - 6 = 8 pints
8 more pints needed

* A Frog sits on a number line at point −10. It is allowed to make up to 4 jumps. First, it can make a jump of 8 units in either direction, or it can skip this jump. Then, it can make a jump 4 units long or skip this jump. Then, it can make a jump 2 units long, or skip this jump. And, finally, it can make a one-unit jump or skip it. Where can it be at the end? Answer: The possible numbers where frog could be are from
Answers
Answer and explanation:
Assuming the frog jumps from -10 for all jumps, if the frog decides to make all 4 jumps then :
8 units jump= -2 or -18
4 units jump= -6 or -14
2 units jump= -8 or -12
1 unit jump = -9 or -11
If the frog decides to make one jump then skip the others then:
Either it makes 8 units jump= -2 or -18
Or 4 units jump= -6 or -14
Or 2 units jump= -8 or -12
Or 1 unit jump = -9 or -11
If it decides to make 2 jumps and skip the others then:
Either it makes 8 units jump= -2 or -18
and 4 units jump= -6 or -14
Or 2 units jump= -8 or -12
and 1 unit jump = -9 or -11
Or any other mix of units of jump twice
If it decides to make 3 jumps and skip the others then:
Either it makes 8 units jump= -2 or -18
and 4 units jump= -6 or -14
and 2 units jump= -8 or -12
Or 1 unit jump = -9 or -11
and 4 units jump= -6 or -14
and 2 units jump= -8 or -12
Or any other mix of 3 jumps
If it decides to make no jump at all then the frog would remain at -10

There are 9 apples and 24 plums in a fruit bowl. What is the ratio of plums to apples?
Answers
Answer:
24:9 or 24 to 9 or [tex]\frac{24}{9}[/tex]
Step-by-step explanation:
The amount of plums is 24. The amount of apples is 9. So to write the ratio of plums (24) to apples (9), you write 24 to 9. You can either write a colon - 24:9 - a to - 24 to 9 - or as a fraction - [tex]\frac{24}{9}[/tex]. But, you have to write it with plums first.
