4.3 × 107 + 9.1 × 108 = _____ x 10 ^----
please help
Answer:
1442.9 = 1.4429 x 10 ^1000
Step-by-step explanation:
PEMDAS
4.3 × 107 + 9.1 × 108 = _____ x 10 ^----
(4.3 × 107) + (9.1 × 108) = _____ x 10 ^---
460.1 + 982.8 = _____ x 10 ^----
1442.9 = 1.4429 x 10 ^1000
This is the right answer, I think you may have forgotten to put the ^.
Answer:
9.53 × 108
Step-by-step explanation:
Make sure both numbers have the same exponent
4.3 × 107 = 0.43 × 108
Then add the coefficients
0.43 × 108 + 9.1 × 108 = 9.53 × 108
Resolución de Problemas con Ecuaciones Lineales
o de Primer Grado.
Ejemplo
Utilizamos el lenguaje algebraico para hacer esa representación.
Sea x número de casos Infectados en Santiago
Sea 2x + 5,088 números de casos Infectados en Sto. Dgo.
Entonces x + 2x + 5,088 = 43,956
x + 2x = 43,956 - 5,088
3x = 38,868
x = 38,868
3
x = 12,912
Luego: x número de casos Infectados en Santiago = 12,912
2x + 5,088 número de casos Infectados en Sto. Dgo. = 2 (12,912) + 5,088 = 31,000 43,956

An electronics store sold 4% of the computers that were on sale.
If only 12 computers were sold, how many computers were not sold?
Answer:
288
Step-by-step explanation:
We can use a proportion to solve this problem:
4 : 100 = 12 : x
x = (12 x 100)/4 = 300 (total computers)
300 - 12 = 288
Which inequality describes the relationship between points A and B on the number line?
Answer:
B > A
Step-by-step explanation:
B and A are both in between 0 and 1 on a number line.
On a number line, the further right you go, the higher numerical values get, and the further left - vice versa.
Anyhow, B is further to the right, as well as closer to 1 than A is, so we can assume that B is the greater number.

Answer:
The figure should be 56 units squared.
Step-by-step explanation:
The long side is 14 units long (6+6+2) and the short side is 4 units long, so 14 multiplied by 4 is 56.
A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simplest form?
–n2 + 3n + 5
n2 + 6n + 1
2n2 + 6n – 1
3n2 + 5
Answer:
n^2 + 6n + 1
Step-by-step explanation:
Firstly, we have to evaluate AB
What we have to do is to multiply A and B
We have this as;
n(2n + 6) = 2n^2 + 6n
Now, we have to subtract the value of C from here and that is;
(2n^2 + 6n) - (n^2 - 1)
2n^2 + 6n - n^2 + 1
= 2n^2 -n^2 + 6n + 1
= n^2 + 6n + 1

Answer:
x = 4
Step-by-step explanation:
Given
[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{x^2+7x+12}[/tex] ← factor the quadratic
[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{(x+3)(x+4)}[/tex]
Multiply through by (x + 3)(x + 4) to clear the fractions
3(x+3) - (x + 4) = x + 9 ← distribute and simplify left side
3x + 9 - x - 4 = x + 9
2x + 5 = x + 9 ( subtract x from both sides )
x + 5 = 9 ( subtract 5 from both sides )
x = 4
Derek bought his truck for $30,000. The value has dropped by $900 each year. He determined that the value of his truck (V) can be modeled by: V = 30,000 - 900x where x is the number of years since he bought his truck.
In how many years will his truck be worth $4,800?
Answer:
28 years
Step-by-step explanation:
The difference between 30,000 and 4,800 is 25200. So we divide this number by 900 to find out how many years it will take for the truck to depreciate to this value

Ann buys a dress in a sale. The normal price of the dress is £36 and it is reduced by 20%. Work out the sale price of the dress.
Reduced by 20% means it is on sale for 80% of the original price ( 100% - 20% = 80%)
Multiply the original price by 80%
36 x 0.8 = 28.80
The sale price is £28.80
what is the additive inverse of 3?
a. -3
b. a+(-a)=0
c. 0
d. -a
Answer:
a. -3
Step-by-step explanation:
Two numbers are additive inverses if they add to give a sum of zero. 3 and -3 are additive inverses since 3 + (-3) = 0. So, -3 is the additive inverse of 3.
