Your beginning balance on your lunch account is $42. You buy lunch for $1.80 every day and sometimes buy a snack for $0.85. After 20 days, you have a balance of $0.05. How many snacks did you buy?
HELP
Answers
First your going to want to multiply the amount of days by how much money a school lunch costs:
1.80 x 20 = $36
The next step you will minus the amount spent by the beginning balance on your lunch account:
42 - 32 = $6
Then you will want to add the amount of money it costs for a snack untill it adds up high enough where it is close to the amount of money left (or you cant add any more):
0.85 + 0.85 + 0.85 + 0.85 + 0.85 + 0.85 + 0.85 = $5.95
You then count the times you added 0.85 which would be 7 times.
You can also multiply 0.85 by 7 to shorten it up:
0.85 x 7 = $5.95
This would leave $0.05 left.
______________________
Final answer:
After 20 days you would have 7 snacks total.

The value of d in the given expression is 2/5.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given an expression as
3/2 = 5d - 1/2
we need to solve for d;
3/2 = 5d - 1/2
5d = 3/2 + 1/2
5d = 4/2
5d = 2
d = 2/5
Hence, the value of d in the given expression is 2/5.

Aldo wants to pour 26.26 grams of salt into a container. So far, he has poured 22.27 grams. How much more salt should aldo pour?
Answers
Answer: 3.99 grams
Step-by-step explanation:
You can easily break this up into 26-22 and .26-.27. 26-22 is equal to 4, while .26-.27 is equal to negative .1. 4 minus .1 is equal to 3.99, so we need to add 3.99 grams more salt to the container.

Referring to the figure, find the surface area
of the pyramid shown. Round to the nearest whole number.
Answers
Answer:
297 is the surface area
Step-by-step explanation:
Ok this problem is very simple.
First lets define some equations.
Area of a triangle: A = 1/2BH
A = Area B = Base H = Height
This equation works for right triangles only.
(because 2 right triangles make a square which is why it's multiplied by 1/2 because it's half a square).
Area of a square: A = BH
Surface area equals all the areas of each side added together.
First lets find the area of one of the triangles.
We know 11 is the base and 8 is the height but the triangle isn't a right triangle.
To make it a right triangle divide the base by 2 so 11/2.
You will get 5.5.
Now find the area!
A = 1/2BH
A = 1/2(5.5)(8)
A = 1/2(44)
A = 22
So now we found the area of the right side as a right triangle but you must multiply it by 2 to get the entire side (because we divided the base by 2).
22(2)=A
44=A
44 is the area of one side of the pyramid but there are 3 other sides (not including the base).
So just do:
44+44+44+44 = A
176 = A
Surface area for the triangles is 176!
Now we must find the area of the square.
A = BH
A = 11(11)
A = 121
Total surface area is all the areas added together so it's:
121+176=A
297

Last question:
Answers
Answer:
y=-3x+7
Step-by-step explanation:
Rise/run
To find slope you can use the rise/run strategy. You count how many units up/down and then how many right/left. between each point on the line, it was down 3 units, right 1 unit (3/1) and since it was going down it would be negative.
As for the y-intercept, you look at where the line crosses the y-axis. In this case it was at (0,7), so the answer would be 7.
Plug your answers in and your equation should be y=-3+7.
You could also do y=7-3x, its the same equation but reversed, so you'll get the same line.
