Answer:
Option A is the correct answer.
Explanation:
There are 6 packages that store 30 baseball cards.
Number of cards in 1 package = 30/6 = 5
Let us consider a as number of packages and b as number of cards.
We have equation for number of cards,
b = 5 a
The constant of proportionality = 5
Option A is the correct answer.
Answer:
900°
Step-by-step explanation:
What is the sum of the measures of the interior angles of a 7-gon?
The formula to measure the interior angles of a polygon
= (n- 2) × 180 °
Where,
n = number of sides
We are given 7 - gon
This means it has 7 sides = Heptagon
Hence,
The measure of the interior angle is given as:
(7 - 2) × 180°
= 5 × 180°
= 900°
The sum of the interior angles of a 7-gon is 900°
Step-by-step explanation:
x - the part
3x one part(first number)
4x second part (second number)
so u have
3x + 4x = 1001
7x= 1001
x = 1001/7
x= 143. First number : 3x = 3• 143 = 429
Second number : 4x = 4• 143= 572
So, 429 and 572 are the numbers
