Answer:
490
Step-by-step explanation:
The ratio of deer to foxes in a country in Texas is 7:3
=>7x: 3x
There are 210 foxes in the country
3x = 210
x = 210/3
x= 70
Therefore the number of deer in the country can be calculated as follows.
= 7x
= 7 × 70
= 490
Hence there are 490 deers in the country
Answer:
w = 10 in
Step-by-step explanation:
Perimeter is the measure of the length of all sides
48 = 2L + 2w
L = w + 4
^ use substitution
48 = 2(w + 4) + 2w simplify.
48 = 2w + 8 + 2w combine like terms
48 = 4w + 8 then subtract 8 from both sides
40 = 4w then divide by 4 to isolate w
10 = w
<u>Answer:</u>
243 students are involved in either sports or music whereas 100 are not
involved in either of it.
<u>Step-by-step explanation:</u>
No. of students who are in music = 115
No. of students who are in sports = 197
No. of students who are in both activities = 69
So, no. of students who are involved either in sports or music,
= (115 + 197 - 69)
=243
So, no. of students who are not involved in either sports or music,
= (343 - 243)
=100
