Donnie is 7 years old. Donnie's age is 3 years less than half of Ana's age. The relationship between their ages can be modeled by the equation 12x−3=7, where x is Ana's age. How old is Ana?

Answer:

The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.

Answer:

Step-by-step explanation:

|x-3x^5|=6+y

y<0

|9-y+6|=21

|15-y|=21

15-y±21

either 15-y=21

-y=6

y=-6

or 15-y=-21

y=36

but y<0

so y=-6

|x-3x^5|=6+y

|x-3x^5|=6-6

|x-3x^5|=0

x-3x^5=0

x(1-3x^4)=0

either x=0

or 1-3x^4=0

or (1-√3 x²)(1+√3x²)=0

1-√3 x²=0

x²=1/√3

x=±√(1/√3)

x²=-1/√3

x=±(1/√3)i

Hey Hey here you go!

according to the chart thing y is the plane and x is hours

Question A-  so the plane(y) goes 600 miles x hours. it says 600 per hour so 600 miles an hour.

Question B- the dependant vriable is 6 from 600. why? because it was the main source for the eqauation and we used it to subract 300 from to get the next answer.

Question C- 600 miles x 600 miles is 1,200 miles. wich would be 1,200 miles for two hours. it said two and a HALF hour so half of 600 is 300 so add that to 1,200 + 300 is 1,500 miles in 2.5 hours (two and a half hours.)

Step-by-step explanation:

The solution to the inequality is c < 6, and it represents that the student can buy a maximum of 5 whole candy bars.

Inequality shows relation between two expression which are not equal to each others.

The given inequality is,

2c – 3 < 9

Simply the inequality,

Add 3 to both the sides,

2c-3+3 <9+3

2c < 12

c < 6

The required inequality is c < 6.

Answer:

Step-by-step explanation:

Let d = # of dimes

Let q = # of quarters

45 = d + q

.1d + .25q = 8.40

Then we can use the substitution method and make it so that d = 45 - q.

Then plug in the value for d into the second equation.

.1(45-q)+.25(q)=8.40

4.5-.1q+.25q=8.40

4.5+.15q = 8.40

.15q = 3.90

q = 26

d = 45 - 26 = 19

26 quarters

19 dimes

Step-by-step explanation:

First term (a) = 64 = t1

Second term (t2) = -32

Common ratio (r) = t2/ t1 = -32 / 64 = - 1/2

Now

Tn =

[tex]a {r}^{n - 1} [/tex]

[tex]t14 = 64 \: ( - \frac{1}{2}) ^{14 - 1} [/tex]

[tex] = 64 \: ( - \frac{1}{2} ) {}^{13} [/tex]

= - 64 * 1 / 8192

= - 1/128
