K=19 which would leave the equation 181=181. The first step to solving this is subtracting 9k from each side.
after you do that it should be k-9=10
now you add 9 to both sides leave k=19. plug k into the equation and get 181=181
Answer:
3 bob's burger= 23.67
2 starry night= 17.98
4 clear= 42
Step-by-step explanation:
3 x 7.89= 23.67
2 x 8.99= 17.98
4 x 10.50= 42
It’s $15.69 for each of the 3 pizzas because 15.69+15.69+15.69=47.07 and then add the delivery fee and it’s 49.57
An algebraic expression that represent how much Mr. Green paid in all is 3(m + 1) + d
<h3 /><h3>Pet fish</h3>
The following represents the items bought
- Each bag has m mollies and 1 bala
- He bought 3 of these bags
The expression that represents the items in a bag is:
He bought 3 bags.
So, the total spent on pet fish is:
<h3>Fish food</h3>
A box costs d dollars.
This means that, the total amount Mr Green spent in the store is:

The nickels in the envelope is $0. 12
<h3>How to determine the number</h3>
From the information given, we have that;
Dimes + nickels = $1. 20
1/4 dimes + dimes = $ 1. 35
Let dimes = d
Nickels = n
d + n = 1. 20 equation a
d/4 + d = 1. 35 equation b
Make 'd' subject from equation a
d = 1. 20 - n
Substitute into equation b
1. 20 - n/ 4 + 1. 20 - n = 1. 35
0. 3 - 0. 25n + 1. 20 - n = 1. 35
collect like terms
- 1. 25n = 1. 35 - 1. 5
- 1. 25 = - 0. 15
n = -0. 15/ -1. 25
n = 0. 12
Thus, the number of nickels in the envelope is $0. 12
