You know that the side of the triangle is 90 cause of the box so u gotta subtract 28 n 26 and add by 90 im p sure
.25 because the / is the same as divided by. So one divided by four is .25. Sorry I don't know how to say this in Spanish.
#2 Linda's estimation of 80÷40=2 was ok. but when she divided, she relized that 43× 2 =86. she cant take away 86 from 82. it should be 1 group of 43. the quoitent is 1 with a remainder of 39
#1 43 × 3 = 129
129 + 28 = 157
157 is the number
hope this helps

Answer:
The son is 20
The man is 60
Step-by-step explanation:
We can set up this equation with what we know. Let <em>m</em> stand for the Man's current age, and let <em>s</em> stand for his son's current age.
We know the Man's current age is three times that of his son, so this equation can be written as: <em>m = 3s</em>
Ten years ago means the man's current age <em>minus</em> 10 years. So it is <em>m-10</em>. So ten years ago he was 5 times his son's age 10 years ago, <em>5(s-10)</em>
This can be written as: <em>m-10=5(s-10)</em>
Solve with either substitution or elimination, the choice is yours, it doesn't really matter which method you use. I'll be using substitution.
<em>m-10=5(s-10)</em>
<em>3s-10= 5s-50</em>
<em>40=2s</em>
<em>20 = s</em>
The son is <em>20</em> years old.
We know the man is currently 3 times his son's age, because <em>m=3s</em>, so just solve for m since you now know the value of <em>s.</em>
<em>m=3s</em>
<em>m=3(20)</em>
<em>m=60</em>
The man is <em>60</em> years old
