Answer:
5
Step-by-step explanation:
let the number be a.
5a=25
divide both sides by 5
5a=25
5divide by 5a is a.
5divided by 25 is 5
therefore,a=5.
the number is 5
Height=15
Explanation:
Area of a triangle= 1/2base x height
Plug in information
30=1/2 x 4 x h
Solve 1/2 x 4 = 2
30= 2 x h
Divide both side by two
30/2=2 x h/2
Solve:
15= h
Answer: 15 + 53/77
Step-by-step explanation:
Multiplying a fraction by 1 does not change the value.
Any number divided by itself is 1.
For instance, 11/11 = 7/7 = 1.
12 + 1/7 + 3 + 6/11 = 15 + 1/7 + 6/11
= 15 + (11×1)/(11×7) + (7×6)/(7×11)
= 15 + 11/77 + (6×7)/77
= 15 + (11 + 6×7)/77
= 15 + 53/77
It is faster to make sure to multiply by the "smallest" form of one that will work, but you don't have to. You only need to make sure that at the end there are no common factors in numerator and denominator, and that numerator is smaller than denominator.
8 halls would be required to accommodate 520 people in the hall.
As we know that a hall can accommodate 65 people.
To determine the number of hall required for 520 people,
first we need to find that how many halls would be required for one person,
So, we will divide the 1 by 6 to find :
The number of one person accommodate = 1/65 Hall
Then, 520 people required to accommodate = 1/65 × 520
= 8 Halls.
[Accommodate: to have enough space for somebody/something, especially for a certain number of people]

This equation of the recipe can be represented as y = x + 5.5 and The constraints are x is ≥ 0 and y is ≥ 5.5.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Otto used 5.5 cups of whole wheat flour and x cups of white flour in the recipe.
The total amount of flour (y) = the total amount of whole wheat flour (5.5) + the total white flour (x).
Therefore, the equation is:
y = x + 5.5
The possible values are
x = 0 or greater to it since the minimum amount of white flour that can be added is 0.
y = 5.5 or greater to it since even if no
white flour is added the minimum total is 5.5.
