Box A is 4. 4 is 5% of the total boxes.
5% = 1/20, so multiply whatever number that's 5% of the total by 20 to get the total.
4 x 20 = 80.
There are 80 marbles total.
Hope this helps!

The total amount in all four boxes is 80

Explanation:
We know that box A has 4 marbles, and it has 5% of the marbles in total. So we can set up a proportion.

4 1% 5%
--- = --- = ---
n 20% 100%



We want to figure out what n is. To do that, we first simplify 5/100 to 1/20. To get from 4 to 1, its divided by 4. We want to do the same thing to n (divide n by 4). To do this, we do the inverse operation of division, and we multiply 20 x 4, which is 80. Therefore, the total amount of marbles is 80.

Find the measures of the four numbered angles
Genrish500 [490]
First, find out x
x+15+2x+15=180
3x+30=180
3x=150
x=50
so the two angels are x+15=65(let's name is ∠5 for convenience), and ∠6= 2x+15=115
notice the two inner lines are marked as congruent, so 
∠4=∠5=65
∠1=180-∠4-∠5=180-65-65=50
Name the right bottom angle ∠7, ∠3=∠7 and ∠3+∠7=the exterior angle 100 degree, therefore, ∠3=50
∠2+∠3=∠4, therefore, ∠2=∠4-∠3=65-50=15
∠1=50, ∠2=15, ∠3=50, ∠4=65

36x+9 equals what<br> big blak vjndjgd
Yuki888 [10]

We can conclude that the equation 36x + 9 equals -1/4.

<h3>What exactly is an equation?</h3>
  • An equation, in its most basic form, is a mathematical statement demonstrating that two mathematical expressions are equal.
  • 3x + 5 = 14, for example, is an equation in which the expressions 3x + 5 and 14 are separated by a 'equal' sign.

So,

  • 36x + 9
  • 36x + 9 = 0
  • 36x = -9
  • x = -9/36
  • x = -1/4

Therefore, we can conclude that the equation 36x + 9 equals -1/4.
