Answer:
x = 2
y = 6
Step-by-step explanation:
x + y = 8
x + (3x) = 8
4x = 8
4x ÷ 4 = 8 ÷ 4
x = 2
-------------------------------
y = 3x
y = 3(2)
y = 6
----------------------------------
x + y = 8
(2) + (6) = 8
8 = 8

Asif wants to buy a Smart Phone for £360. He has already saved £105.
Each week he is paid £90. He saves 25% of his pay.
How many more weeks must he save for to afford the phone?
Answer:
12
Step-by-step explanation:
100%->£90
1%->£90÷100=£0.90
saves->25%->£0.90×25=£22.50
£360-£105=£255
£255÷£22.50=11
11+1=12

Answer:
Suppose that we have a circle of radius R.
The total perimeter of this circle will be:
P = 2*pi*R
Where pi = 3.14159...
Now, if we have a section of this circle with an angle A, the "chord" of this section will be:
C = (A/360°)*2*pi*R.
Where you can see that if A = 360° (so the section is the whole circle) the chord is equal to the perimeter.
In this particular case, the chord is equal to the radius of the circle, then we get:
C = R = (A/360°)*2*pi*R
We need to solve this for A.
R = (A/360°)*2*pi*R
We can divide both sides by R to get:
1 = (A/360°)*2*pi
Now we need to isolate A.
(360°/2*pi) = A = 57.3°
This would be the angle in the minor arc.
And the angle for the mayor arc would be the difference between the angle for a whole circle (360°) and the angle of this section (57.3°)
The angle for the major arc is:
A = 360° - 57.3° = 302.7°

Solve problem using substitution
2x + y = 10
y = x + 1
Answer:
x = 3
y = 4
Step-by-step explanation:
2x + y = 10 -----------------(I)
y = x + 1 ---------------------(II)
Substitute y = x + 1 in equation (I)
2x + x + 1 = 10 {Combine like terms}
3x + 1 = 10 {Subtract 1 from both sides}
3x = 10 -1
3x = 9 {Divide both sides by 3}
x = 9/3
x = 3
Plugin x = 3 in equation (II)
y = 3 + 1
y = 4

This box plot shows information about the marks scored in a test.
a) What was the median number of marks scored?
b) What was the interquartile range of the marks?
c) What was the range of the marks?
Answer:
a) 58
b) 38
c) 76
Step-by-step explanation:
a) Here we want to get the median
The median of the number is the 3rd line
The value here is 58
b) The interquartile range is the difference between the first and third quartile
The third quartile is the 4th line and its value is 72
The first quartile is the second line which is 34
The interquartile range is thus; Q3-Q1
= 72-34 = 38
c) The range is the difference between the highest and lowest values
The highest value is 86
The lowest value is 10
The range is thus;
86-10 = 76

1. The amount paid for different weights of oranges at a farmer’s market are shown below. Oranges (lb) Price ($) 2 3 3 4.50 5 7.50 ? 12 (a) Is the relationship between the price and the weight of the oranges proportional? Use the first three rows of data to answer this question. Show your work and explain. How many pounds of oranges cost $12? Show your work.
due today.
Answer:
Relationship is proportional ;
8 oranges
Step-by-step explanation:
Oranges (lb) 2 ___ 3 ____5 ___?
Price ($) __ 3 ___4.50___7.50_12
For proportionality :
Oranges = k * price
Where, k = constant of proportionality
2 = 3k
k = 2 /3
k = 0.666666
Using k :
Number of oranges at price = 4.50 should be:
0.66666 * 4.50 = 3
Number of oranges at price = 7.50 should be:
0.66666 * 7.50 = 5
Hence, relationship is proportional
Number of oranges at $12
0.66666 * 12 = 8

Solve for x your answer must be simplified. -4+x<9
Answer:
x<13
Step-by-step explanation:
To solve this, we want to have the isolate the variable x on the left side, by itself without a coefficient. All we have to do to do this is add 4 to both sides, cancelling out the -4 and getting x<13
Answer:
x = 13 + y
Step-by-step explanation:
Simplify:
-4 + x = y + 9
Reorder the terms:
-4 + x = 9 + y
Move all terms containing x to the left all other terms to the right
Add 4 to each side of the equation
-4 + 4 + x = 9 + 4 + y
Combine like terms: -4 + 4 = 0
0 + x = 9 + 4 + y
x = 9 + 4 + y
9 + 4 = 13x = 13 + y
Answer:
x = 13 + y
