The change in the value of x, as a percentage, is given by:
The percentage change is given by the change multiplied by 100% and divided by the initial value.
In this question, x varies from to
, which means that the initial value is a, and the change is b - a. Then, the percentage chance in the value of x is given by:

Answer:
Step-by-step explanation:
i. b is how many times as large as a?
b/a
ii. Therefore, b is what percent of a?
b/a*100
iii. Hence, if x varies from x=a to x = b, x changes by what percent?
(100b)/a-100

Answer:52°
Step-by-step explanation:
x+x+14=90
Collect like terms
x+x=90-14
2x=76
Divide both sides by 2
2x/2=76/2
x=38
angle (x+14)°=(38+14)°=52° which is vertically opposite to angle PKQ.
Since Vertically opposite angles
Therefore angle PKQ=52

Answer:
A=0.25
B=0.35
C=1.05
Step-by-step explanation:
1. A+B=0.6
2. A+C=1.3
3. C=3B
2 subtract 1:
- C-B=0.7
3 substituted:
- 3B-B=0.7
- B=0.35
- C=0.7+0.35=1.05
- A=0.6-0.35=0.25
Choose the polynomial written in standard form.
xy2 + 4x4y + 10x2
x4y2 + 4x3y + 10x
x4y2 + 4x3y5 + 10x2
x6y2 + 4x3y8 + 10x
Answers
Answer:
Standard form means that you write the terms by descending degree.
x^4y^2 + 4x^3y + 10x^2
The degree of the first term x^4y^2 is 4+2=6
The degree of the second term 4x^3y is 3+1=4
The degree of the third term 10x^2 is 2
The terms are written by descending degree. Therefore, polynomial x^4y^2 + 4x^3y + 10x^2 is written in standard form.

-2(bx-5)=16
If b is 3, then it changes to -2(3x-5)=16
We want to find x, right? Then we must do -2•3x and -2(-5). The result would be -6x and 10.
Then again, the equation would change -6x+10=16
Which would be -6x=6
Is x=6/6
And then x would be 1

Answer:
a) The equation of Z and C is Z =K C
b) K = 2
Step-by-step explanation:
Explanation:-
Given data Z is directly proportional to C
⇒ Z ∝ C
⇒ Z = K C
The equation of relating Z and C
Z = K C
Given Z = 20 and C =10
20 = K ( 10)
⇒ K = 2
