Answer:
Value of stamp collection = (45b + 43) cents
Step-by-step explanation:
What we have here is as follows;
if there are x 3-cent stamps, then there are 4x 10-cent stamps
So the number of 2-cent stamps is 1 less than 3 cent stamps and that will be x-1 2 cent stamps
Number of 2 cents stamps = b
This means that x-1 = b
Thus, x = b + 1
So the value of the stamp collection is as follows;
x 3 cents stamps = 3(b+ 1) = 3b + 3 cents
4x 10 cents stamps = 10(4(b + 1)) = 10(4b + 4) = 40b + 40
value of the 2 cents stamp = 2b cents
Total value is thus;
2b + 40b + 40 + 3b + 3 = (45b + 43) cents
Answer:
Step-by-step explanation:
Given a triangle.
One of the angles is 
more than 5 times of one angle.
Third angle is 
more than the difference of two angles.
To find:
The angles.
Solution:
Let the first angle = 
As per question statement, second angle = 5 +
And third angle = 5 + - + = 
Using triangle sum property that the sum of all the internal angles of a triangle is always equal to 
.
Therefore, the first angle = 
The second angle = 
The third angle = 
Therefore, the angles are .
if x =7 then plug in 7 for x
4(7) - 2((7)+a) = 8
28 - 14 -2a = 8
14 - 2a = 8
-2a = -6
a = 3
Answer:
X^2-9=0 is x2 = 9
Step-by-step explanation:
Answer:
Sophomore=S
Juniours =J
there are 22 more S than J means,
J=S+22.....................................................................1
total is 48 means
J+S=48
S+22+S=48 (put the value of J here from 1)
2S=48-22
2S=26
S=26/2
S=13
now put the value of S in 1 to find juniours
J=S+22
J=13+22
J=35
so, in the cooking class sophomores are 13 and juniors are 35.
