Answer:
Step-by-step explanation:
has to sweep 4/6
already swept 3/6
it needs to sweep 1/6 because
4 / 6-3 / 6 = 1/6
Since they are fractions with the same denominator, you place the same denominator and subtract the numerators.
Answer:
3 digits to the left side
Step-by-step explanation:
The decimal point will move 3 digits to the left side when dividing a decimal by 10³.
Answer:
3.19
Step-by-step explanation:
To solve 10x-35+3ax=5ax-7a, we'll need to assume that a is a constant and that we are to solve for the variable x. To accomplish this, group all the x terms together on one side and all of the no-x terms on the other:
10x + 3ax - 5ax = -7a + 35
Factoring x out of the left side, we get:
x(10 - 2a) = 7(5 - a). Dividing both sides by (10 - 2a), we get:
7(5 - a)
x = ------------ = 7/2
2(5 - a)
x has the value 7/2.
Answer:
360°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 4, hence
sum of interior angles = 180° × 2 = 360°
