IKEA has 6428 glass tables. 5472 People bought glass tables. How many Glass tables left? ikea needs a raise man®™™™‰£
ok awnser
Answer:
956 glass tables would be left.
Step-by-step explanation:
Well, if each person bought a single table and since it would be impossible for all of them to by more than 1 or to buy an amount between 2 and 1, we can find the answer by subtracting 5472 from 6428.
6428 - 5472 is equal to 956.

What is the solution to the equation 2(×+2. 4)=6. 4
Answer:
0.8
Step-by-step explanation:
2x + 4.8 = 6.4
2x = 6.4 - 4.8
2x = 1.6
x = 0.8
Answer:
x = 0.8Step-by-step explanation:
In the question we're given with an equation that is 2 ( x + 2.4 ) = 6.4 . And we're asked to find the solution of the equation that means we have to find the value of x .
Solution : -
[tex] \longmapsto \: 2(x + 2.4) = 6.4[/tex]
Step 1 : Removing parenthesis by multiplying 2 with x and 2.4 :
[tex] \longmapsto \: 2x + 4.8 = 6.4[/tex]
Step 2 : Subtracting 4.8 on both sides :
[tex] \longmapsto \: 2x + \cancel{4.8} - \cancel{4.8 }= 6.4 - 4.8[/tex]
On further calculations :
[tex] \longmapsto \:2x = 1.6[/tex]
Step 3 : Dividing by 2 on both sides :
[tex] \longmapsto \: \frac{ \cancel{2}x}{ \cancel{2 }} = \frac{1.6}{2} [/tex]
Calculating further :
Here , we have removed decimal from 1.6 . So it'll become 16 and 10 it'll divided by 10
[tex] \longmapsto \:x = \cancel { \frac{16}{2}} \times \frac{1}{10} [/tex]
Step 4 : Cancelling 16 by 2 :
[tex] \longmapsto \:x = \frac{8}{10} [/tex]
[tex] \longmapsto \: \green{\underline{ \green {\boxed{x = 0.8}}}}[/tex]
Therefore value of x is 0.8 .Verifying : -
We are verifying our answer by substituting value of x in given equation. So ,
2 ( x + 2.4 ) = 6.42 ( 0.8 + 2.4 ) = 6.42 ( 3.2 ) = 6.46.4 = 6.4L.H.S = R.H.SHence, Verified .Therefore, our value for x is correct .

a.d<-14
b. d> 6
c. -14 < d<6
d. d<-14 or d > 6
Answer:
b. d > 6
Step-by-step explanation:
Answer:
D. d<-14 or d>6Step-by-step explanation:
To solve for d, isolate it on one side of the equation.
|d+4|>10
d+4<-10 or d+4>101. d+4<-10First, you have to subtract by 4 from both sides.
[tex]\sf{d+4-4 < -10-4}[/tex]
Solve.
Add or subtract the numbers from left to right.
-10-4=-14
[tex]\Longrightarrow: \boxed{\sf{{d < -14}}}[/tex]
2. d+4>10Subtract by 4 from both sides.
[tex]\sf{d+4-4 > 10-4}[/tex]
Solve.
Subtract the numbers from left to right.
10-4=6
[tex]\Longrightarrow: \boxed{\sf{d > 6}}[/tex]
Therefore, the correct answer is "D. d<-14 or d>6".I hope this helps. Let me know if you have any questions.

4x+3y=9 and 3x +4y = 36
The solution of the system of equations:
( -16.7, 19.28)
How to solve the system of equations?
Here we have the system:
4x+3y=9
3x +4y = 36
First, we need to isolate one of the variables in one of the equations, let's isolate x on the second one:
x = 36/3 - (4/3)y = 9 - (4/3)y
Now we can replace this in the other equation:
4*(9 - (4/3)y) + 3y = 9
36 - (16/3)y + (9/3)y = 9
- (7/3)y = -36 - 9 = -45
y = (3/7)*45 = 19.28
To get the value of x, we get:
x = 9 - (4/3)*19.28 = -16.7
Then the solution of the system is ( -16.7, 19.28)

April sold 85 tickets to a school play
and collected a total of $495. If adult tickets cost $10 each and child
tickets cost $5 each, how many adult tickets and how many child tickets did she sell?
Answer:
adult tickets =14
child tickets =71
Step-by-step explanation:
x is adult tickets
y is child tickets
x+y=85
10x+5y=495
y=85-x
2x+y=99
2x+（85-x）=99
x=99-85=14

Which of the following is the difference of two squares? 16a^2-9b^6 4g-16h 25m^2+100n^2 2x^2-4y^2
Answer:
16a^2 - 9b^6
Step-by-step explanation:
16a^2 - 9b^6 ---> 16a² is the square of 4a; 9b^6 is the square of 3b³
This is the difference of 2 squares
4g - 16h ---> 4g and 16h are not perfect squares.
25m^2 + 100n^2 ---> this is a sum of squares, not a difference of squares
2x^2 - 4y^2 ---> 2x² is not a perfect square
Answer: 16a^2 - 9b^6

Which triangle would be most helpful in finding the distance between the points (-4,3) and (1, -2) on the coordinate
plane?
Answer:
Right Triangle, the distance between these two coordinates is 5.83 in whatever unit you're measuring.
Step-by-step explanation:
Generally when you're using triangles to find the distance between two graphed points, you're using a right triangle.
[tex]9 + 25 = 34\\\sqrt{34}=5.83[/tex]The reason behind that being you can draw lines on the x and y axis of these points and find where they connect. After doing so, you can directly connect the two points and create a right triangle.
To find the distance between the two points using a right triangle, we can use the formula for the hypotenuse: [tex]a^2 + b^2=c^2[/tex]
A and B is the distance between the point and where the lines you've drawn intersect. C is the resulting distance between the two points.
Plugging in A and B, which is 3 and 5, we can find C. 3 squared is 9 and 5 squared is 25.
[tex]3^2 + 5^2 = 9 + 25[/tex]
Now we add the two and find the square root.
[tex]9+25=34\\\sqrt{34} =5.83[/tex]
Your answer is 5.83

A bag contains red, blue and yellow counters in the ratio 2:3:5
a) What fraction of the counters are red?
b) 9 of the counters are blue. How many of the counters are yellow?
c) How many counters are in the bag?
Pls reply with answers to a,b and c please.
Thanks
Answer:
a) 2/10
b) 15
c) 30
Step-by-step explanation:
Ratio: 2:3:5 = R:B:Y
If we add them all together, we can find the denominator for the fraction of how many counters are in the bag. 2+3+5 = 10.
If the ratio for R = 2, then the fraction is 2/10 (simplified)
If 9 of the counters are blue, to find the number of the other counters, we multiply the ratio numbers by 3 (because 3 x 3 is 9). So, the number of red counters is (2x3) 6, blue is 9, and yellow is (5x3) 15.
Now, to find the total amount, we can add 6, 9, and 15 together to get 30.
