What’s the answer to this ???

Answers

Answer 1

Answer:

-5, 3

Step-by-step explanation:

3) 10+3n=20+5n Set up the problem

-3n -3n Subtract 3n from both sides to get n on one side of the equation.

10 =20-2n

-20 -20 Subtract 20 from both sides to isolate n

-10 =2n

/2 /2 Divide both sides by 2 to isolate n

-5 = n

4) 18=2(b+6) Write down problem

18=2b+12 Distribute

-12 -12 Subtract 12 from both sides to isolate b

6=2b

/2/2 Divide both sides by 2 to isolate b

3=b

Answer 2

Answer:

3) 3x+10 = 5x+20

=> 3x-5x= 20-10

=> -2x= 10

=> x = 10/-2

=> x= -5

4) 2(b+6) = 18

=> 2b +12 = 18

=> 2b = 18-12

=> b= 6/2

=> b = 3

Answers

Answer:

Step-by-step explanation:

To find the perimeter, add up the length of the sides

P = 27z+ 20+ 9z+ 24+ 12z+ 30+ 6z+ 14

Combine like terms

P = 27z+9z+12z+6z+20+24+30+14

Your piggy bank starts with $20 and then you add $3 to it every day . Use an equation in slope intercept form to model the amount of money in the piggy bank to determine how much there is after 5 days.

Answers

9514 1404 393

Answer:

y = 3x +20

$35 after 5 days

Step-by-step explanation:

The "slope" is the amount added each day. The "intercept" is the initial amount in the bank. If y represents that amount and x represents the number of days money is added, then the slope-intercept equation is ...

y = 3x +20

When x=5, the value is ...

y = 3(5) +20 = 15+20

y = 35 . . . . amount of dollars in the bank after 5 days

Answer:

450 online tickets

200 gate tickets

Step-by-step explanation:

Let x = no. of online tickets

and y = no. of gate tickets

60x = total sales of online tickets

80y = total sales of gate tickets

x + y = 650 and 60x + 80y = 43000

y = 650 - x 60x + 80(650 - x) = 43000

60x + 52000 - 80x = 43000

-20x = -9000

x = 450 online tickets

y = 650 - 450 = 200 gate tickets

Which package has the better unit price per bottle. 48- pack of 8- ounce bottle or 28- pack of 10- ounce per bottle

Answers

Answer:

Step-by-step explanation:

There is the need to know the cost of both packs. Although, I'm inclined to believe that the 48 pack of 8 ounce per bottle is the cheapest, but that might not be the case if the difference in their prices(with respect to the 28 pack of 10 ounce per bottle) is very high.

Succinctly put, if the price difference between both are close, then the 48 pack of 8 ounce per bottle is the cheapest. But if the price of the 28 pack of 10 ounce per bottle is significantly lower, then it is the cheapest

Ben and Jerry are driving to Chicago and it takes 270 miles to get there. They

have already traveled 42 miles and are driving 75 mi/h. Write a function that

models the distance they drive as a function of time.

Answers

Answer:

d= 75*t

Step-by-step explanation:

Given data

We are given that the total distance = 270 miles

And that they have already traveled 42 miles

speed= 75mi/h

The remaining distance of the journey is = 270-42

= 228 miles

We know that

speed= distance/time

distance= speed*time

also

d= 75*t

Hence, we can estimate the distance they have traveled for any number of time t

a. 8 1/4

Step-by-step explanation:

so 2*4= 8, that part is easy.

1/8*2= 2/8 because when you multiply whole numbers with fractions, you're basically multiplying it with a one as the denominator, so in this case, 1/8*2/1. which again equals 2/8. simplify 2/8 and you'll get 1/4.

put them together and you'll get 8 1/4

Kurt is financing a $315,000 mortgage for 30 years at a fixed rate of 7.35%. What is the total cost of the principal and interest after 30 years?

Given data

P= $315,000

t= 30years

r= 7.35%

Let us apply the simple interest formula

A= P(1+rt)

substitute

In the equation 6(5k-8)-20= 11(2k-3)+3k
I know you would solve inside the parenthesis 6 times 5k gives you 30k but when you multiply the 8 should it be 6 times -8 or 6 times 8?

Answers

Answer:

k = -1

Step-by-step explanation:

6(5k-8)-20= 11(2k-3)+3k | Given

30k - 48 - 20 = 22k - 33 + 3k | Distribute

30k - 28 = 25k - 33 | Add numbers & combine like-terms

30k = 25k - 5 | Add 28 to both sides

5k = -5 | Subtract 25k from both sides

k = -1 | Divide -5 by 5

Answer:

Step-by-step explanation:

6(k + 2) + 1 = 13 (distribute 6 around the k+2)

6k + 12 + 1 = 13 (add 12 and 1)

6k + 13 = 13 (subtract 13 from both sides)

6k = 0 (divide by 6)

k = 0

Answer:

6( k + 2 ) + 1 = 13

6k + 12 + 1 = 13

6k + 13 = 13

6k = 0

k = 0/6

so it will 0
