Answer:
24x + 48
Step-by-step explanation:
12(2x) + 12(4) = 24x + 48
Answer:
Answer:
y = 16/25x³
Step-by-step explanation:
If y is inversely proportional to a^3, this is expressed as;
y∝1/a³
y = k/a³ where k is the proportionality constant
Given a=2, y=10, then 10 = k/2³
k = 10*2³
k = 80
Substituting k = 80 back into the formula;
y = 80/a³ ............. 1
Similarly, if a is directly proportional to x, then a ∝ x i.e a = kx
If x=4, a=20 then;
20 = 4k
k = 20/4
k = 5
Substituting k = 5 back into the formula;
a = 5x ....... 2
Substitute equation 2 into 1;
y = 80/a³
y = 80/(5x)³
y = 80/125x³
y = 16/25x³
Hence the formula for y in terms of x is y = 16/25x³
Step-by-step explanation:
X/42 = 3/7
(x * 7) = (42 * 3)
7x = 126
x = 126/7
<u>x = 18</u><u />

The distance between the pinwheel galaxy and the power kilo-light-years in standard form is 27000
<h3>How to represent the number in standard form?</h3>
The distance between the pinwheel galaxy and the power kilo-light-years is given as:
d = 2.7 × 10^4
Evaluate 10^4
d = 2.7 × 10000
Evaluate the product
d = 27000
Hence, the distance between the pinwheel galaxy and the power kilo-light-years in standard form is 27000
