Answer:
4²
Step-by-step explanation:
When dividing squares, we just subtract the exponents from each other. Therefore 7 - 5 = 2 so we get 4².

Emma had 10 Balls in a bag. The balls were numbers 1 through 10. She wanted to test the probability of drawing a ball that is a multiple of 3.
Also, write a prediction about if there is an unlikely, impossible, likely, even, or certain change of drawing a multiple of 3.
Answer:
30%UnlikelyStep-by-step explanation:
The balls - multiples of 3 are:
3, 6 and 9The probability of a multiple of 3 is:
3 out of 10 orP = 3/10 = 30%30% probability is in the range 0%-50% so this event is unlikely
Total multiples=3
[tex]\\ \sf\longmapsto P(3)=\dfrac{Multiples\:of\:3}{Total \:balls}[/tex]
[tex]\\ \sf\longmapsto P(3)=\dfrac{3}{10}[/tex]
[tex]\\ \sf\longmapsto P(3)=30\%[/tex]
It is <50%;So it is unlikely to happen.

Brigit has 4.4 ounces of black beans for lunch. Each ounce of the black beans contains 1.3 g of fiber. How much fiber is contained in the black beans
Answer:
[tex]5.72[/tex]g of fiber is contained in the black beans.
Step-by-step explanation:
Given:
No.of. ounces[tex]=4.4[/tex]
Each ounce contains [tex]1.3[/tex]g of fiber
To calculate the fiber contained in the black beans
Total Fiber = No.of. ounces × Fiber contained in each ounce
[tex]=4.4[/tex] × [tex]1.3[/tex]
[tex]=5.72[/tex]g
Therefore, fiber contained in the black beans is [tex]5.72[/tex]g.

Write first four terms of an AP when the first term is -2 and common difference is O.
Explanation:
If the common difference is 0, then we're adding 0 to each term to get the next term. However, adding 0 doesn't change the number. So that's why we have the same thing written four times.
As another example, let's say the common difference was 1 instead of 0. That would mean the first four terms are -2, -1, 0, 1 since we add 1 to each term to get the next one (eg: -2+1 = -1).
Answer:
-2, -2, -2, -2.
Step-by-step explanation:
If the common difference (d) is 0 then all terms are the same as the first:-
AP = a, a + d, a + 2d, a + 3d
Here we have -2, -2+0, -2 + 2(0), -2 + 3(0)
5-2x=-4x+9
Answer step by step
Answer:
x = 2
Step-by-step explanation:
5-2x = -4x+9
5+(-2x+4x) = (-4x+4x)+9 [Add 4x to each side to get ride of 4x on the right]
5+2x = 9
(5-5)+2x = (9-5) [subtract 5 from both sides to get rid of 5 on the left]
2x = 4
2x/2 = 4/2 [Divide each side by 2 to get x alone]
x=2
The solution to the equation 5 - 2x = -4x + 9 is x = 2.
Here, we have,
To solve the equation 5 - 2x = -4x + 9 step by step, we will combine like terms and isolate the variable x.
Here's how:
Start by simplifying both sides of the equation by combining like terms:
5 - 2x = -4x + 9
The left side has no like terms to combine, so we move to the right side:
-2x + 4x = 9 - 5
Simplifying further:
2x = 4
Now, we want to isolate the variable x.
To do that, we need to get rid of the coefficient 2 that is multiplied by x.
We can achieve this by dividing both sides of the equation by 2:
(2x)/2 = 4/2
Simplifying further:
x = 2
We have found the solution for the variable x.
Therefore, the solution to the equation 5 - 2x = -4x + 9 is x = 2.

Answer:
I Kg = 1000 g
3 Kg = 3000 Kg
Step-by-step explanation:
Kg - Hg - Dag - g
1 Kg - 10 Hg - 100 Dag - 1000 g
So, 1 Kg = 1000 g
3 Kg = 3(1000)g = 3000 g

In the function above n is a constant if f(9)=4 what is the value of f(-3)
Answer:
This equation is in y=mx + b form. Just plug in the point to get N, which is also B.
Whatever is in f(x) is your x. So x = 9; This means...
4 = 2/3(9) + n
Solving for n gets you -2.
Now we plug in -3 and also substitute N now that we solved for it.
f(-3) = 2/3(-3) - 2
f(-3) = -4

Sixteen is equal to 7 increased by the product of 3 and a number.
Answer:
number is 3
Step-by-step explanation:
let the number be n then the product of 3 and the number is 3n , so
16 = 7 + 3n ( subtract 7 from both sides )
9 = 3n ( divide both sides by 3 )
3 = n
That is the number is 3

Dilation by a scale factor of 4 and a reflection over the x-axis
Answer:
(-12, -20).
Step-by-step explanation:
A dilation of factor 4 moves (-3, 5) to (-3*4, 5*4) = the point (-12, 20).
A reflection over the x-axis is (x, y) ------> ( x, -y).
So ( -12, 20) goes to (-12, -20).
