Answer:
<em>15 people</em>
Step-by-step explanation:
since Raul and his friends each weigh 1/20 ton,
and the total weight reads 3/4 ton
The total number pf people on the scale will be:
<em>The total weight of Raul and his friends divided by their individual weight</em>
==> (3/4 ton) ÷ (1/20 ton)
= 3/4 X 20/1 = <em>15 people</em>
Answer: There are 24 patients who had allergies or ear infections but not both.
Step-by-step explanation:
Since we have given that
Number of patients having ear infections = 9
Number of patients having allergies = 15
We need to find the number of patients had allergies or ear infections, but not both.
According to Venn diagram , we get that
Number of patients had allergies or ear infections is given by

Hence, there are 24 patients who had allergies or ear infections but not both.
Answer:
F.IF.B.4: Graphing Linear Functions
1 What is the y-intercept of the graph of the line
whose equation is y = −2
5 x + 4?
1) −5
2
2) −2
5
3) 0
4) 4
Step-by-step explanation:
If x = -6
we can subtitution x to every inequality, so :
-5 - 3x > 10
-5 - 3(-6) > 10
-5 - (-18) > 10
-5 + 18 > 10
13 > 10 [true]
-3 - 5x < -14
-3 - 5(-6) < -14
-3 - (-30) < -14
-3 + 30 < -14
27 < -14 [false]
2 - x < -3
2 - (-6) < -3
2 + 6 < -3
8 < -3 [false]
So if x=-6, inequality true is -5 - 3x > 10.
