Answer:
x = -8.4
Step-by-step explanation:
You do the inverse operations:
The inverse of division is multiplication, so:
x/1.2 = -7 (x 1.2) - multiply by 1.2
x = -8.4
Plzzz help
Solve v+8<3or -8v<-40
v < −5 or v > 5
We know either v+8<3 or −8v<−40
Possibility 1
v+8<3
v+8−8<3−8
Subtract 8 from both sides
v<−5
Possibility 2
−8v<−40
−8v −8 < −40 −8
Divide both sides by -8
v>5

The population of Town A is 1.26 x 10^5 people. The population of Town B is 2.8 x 10^4 people. How many times greater is the population of Town A than the population of Town B?
The population of town A is 4.5 times greater than the population of town B.
What is the power of a number?The power of a number describes how many times a number is multiplied by itself.
Given are the population of two towns A and B.
Town A has a population of 1.26×10⁵ and the population of town B is 2.8×10⁴.
To find how many times greater is the population of Town A than the population of Town B we have divide the population of town A by the population of town B which is,
= ( 1.26×10⁵)/(2.8×10⁴) times greater.
= (12.6)/(2.8). ( 10⁵ divided by 10⁴ is 10¹ which is 10)
= 4.5 times greater.

6-4(a+2)=8+a
What dose a equal
Answer:
-2 =a
Step-by-step explanation:
6-4(a+2)=8+a
Distribute
6 - 4a - 8 = 8+a
Combine like terms
-2 -4a = 8+a
Add 4a to each side
-2-4a+4a=8+a+4a
-2 = 8+5a
Subtract 8 from each side
-2-8 = 8+5a -8
-10 = 5a
Divide each side by 5
-10/5 = 5a/5
-2 =a

What is -5n+7<57 and 6n+2<8
Answer:
if -5n+7<57, then n>-10.
if 6n+2<8, then n<1.
Step-by-step explanation:
-5n+7<57
1. subtract 7 from both sides:
-5n+7 -7< 57 -7
-5n<50
2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):
-5n ÷-5<50 ÷-5
n>-10
6n+2<8
1. subtract 2 from both sides:
6n+2 -2<8 -2
6n<6
2. divide both sides by 6:
6n ÷6<6 ÷6
n<1

Answer:
1) = 180 degree reason = being AB is a straight line or supplementary
2) = angle AOB reason = being all the angles are of a straight line AB
3) = x + 2x+34 + 20 = 180 degree. reason being supplementary angle
4) = 42 degree
1) fill 180° in the blank
Reason :
Because AOB angles is half a page so it equals 180°

2)fill 180° in the blank
Reason :
AOE + EOF + FOB = AOB
And we have found that AOB angles is half a page so it equals 180°

The vertex of this parabola is at (-1,-3). Which of the following could be its equation?
61,-3)
A. x=-2(y + 1)2-3
B. x=-2(y-1)2-3
C. x= -2(y + 3)2-1
D. x = -2(y-3)2-1
Answer:
NONEThe vertex form of an equation of the parabola with vertex (-1,-3) is:
y = a(x + 1)² - 3where a could be any number, also -2,
Step-by-step explanation:
The vertex form of an equation of the parabola:
y = a(x - h)² + k
vertex is (-1, -3) so h = -1, k = -3
so:
y = a(x - (-1))² + (-3)
y = a(x + 1)² - 3

-x^2+15x-44
factor the equation
Answer:
- (x - 4)(x - 11)
Step-by-step explanation:
Given
- x² + 15x - 44 ← factor out - 1 from each term
= - 1 (x² - 15x + 44) ← factor the quadratic
Consider the factors of the constant term (+ 44) which sum to give the coefficient of the x- term ( - 15)
The factors are - 4 and - 11 , since
- 4 × - 11 = + 44 and - 4 - 11 = - 15 , thus
x² - 15x + 44 = (x - 4)(x - 11) and
- x² + 15x - 44 = - (x - 4)(x - 11)

Descartes' rule of sign is used to determine the number of real zeros of a polynomial function. It tells us that the number of positive real zeroes in a polynomial function f(x) is the same or less than by an even numbers as the number of changes in the sign of the coefficients.
3x= 5+7x solve for x
Answer:
x = -5/4
Step-by-step explanation:
3x= 5+7x (subtract 7x from both sides)
3x - 7x = 5
-4x = 5 (divide both sides by -4)
x = 5/(-4)
x = -5/4
this is kinda confusing but it says “if 1 cm represents 2 meters, how long would each measurement be on an actual basketball court?”
Answer:
28 m15 m24.8 m1.0 mStep-by-step explanation:
The given statement is the scale factor:
[tex]\dfrac{\text{scale distance}}{\text{actual distance}}=\dfrac{1\text{ cm}}{2\text{ m}}[/tex]
This can be rearranged to the formula ...
[tex]\text{actual distance}=\text{(scale distance)}\dfrac{2\text{ m}}{1\text{ cm}}[/tex]
Filling in the given scale distances, you find the actual distances to be ...
[tex]\textbf{(a) }(14\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=14\cdot2\text{ m}=28\text{ m}\\\\\textbf{(b) }(7.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=7.5\cdot2\text{ m}=15\text{ m}\\\\\textbf{(c) }(12.4\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=12.4\cdot2\text{ m}=24.8\text{ m}\\\\\textbf{(d) }(0.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=0.5\cdot2\text{ m}=1.0\text{ m}\\\\[/tex]
