100 + 20 x n = 400
Step-by-step explanation:
If he ended the game with 400 points, and he scored 100 points in the first round, and 20 points every round after that, then we have to find out how many rounds he played using multiplication and addition. n represents the number of rounds he played, which is what we want to find out. What number do you have to multiply 20 by to get 300? the answer is 10. Therefore, n is 10.

Tell whether (4, 27) is a solution of y=3x+15
Answer:
Yes
Step-by-step explanation:
We have two properties for our question :
(4, 27)
y = 3x + 15
We are being asked whether the point (4, 27) is a solution of y = 3x + 15
So how do we figure this out? Well, what we have to know first that (4, 27) represents a variable, 4 which is the run on the graph, represents x in a solution. And 27 which is the rise on the graph, represents y in the solution. So when asking for a solution with two points, all we must do is substitute x and y for the two coordinates.
y = 3x + 15
y = 27 and x = 4
27 = 3(4) + 15
27 = 12 + 15
27 = 27
Since this equation is true with the respected variables, therefore signifies that (4,27) is a solution of y = 3x + 15

pls help me ASAP!! what is the surface area of this design? a) 288in b) 256in c) 96in d) 160in
Answer:
b) 256 inches
Step-by-step explanation:
8x5x2 = 80 (top & bottom)
8x5x2 = 80 (front & back)
8x8x2 = 128 (gross area of 2 sides)
4x4x2 =32 (delete this for side cutouts) Guessing the cutoff dimension on
left side is 4m inch.
80+80+128-32 = 256 inches

One of the two numbers ends in zero. If you cross out the zero, you get the second number. Find these numbers if their sum is 363.
Answer:
330 + 33 = 363
Step-by-step explanation:
The answers you are looking are 330 and 33.
If you were to take 330 and 33 and add them together, it would equal 363. The question also states if you were to take the 0 off of the first number (330), youd get your second number (33) to equal the sum given.
I hope this helps!
- Mia and Lily are trying to find the nearest whole number to the square root of 120
Mia: It is 10
Lily: It is 11
Who is correct?
Give a reason for your answer.
For determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.
Given that,
Mia has 10 number.And, Lily is 11 number.Now if we square both the numbers so it comes:
10^2 = 10011^2 = 121So, 121 is nearest to 120.
Therefore we can conclude that for determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

Use the multiplier method to increase £258 by 43%
You must show your working out.
Answer:
£368.94
Step-by-step explanation:
The multiplier for 43% is 0.43
0.43 x 258 = 110.94 which is 43%
But if you are increasing 258 by 43% you must add on 258 as well
Or instead you can just do 258 x 1.43= 368.94
