Answer:
b= 3.5
s= 10.5
p=21
Step-by-step explanation:
b for brush
s for sketch book
p for paint set
b=1/3s
s= 1/2 p
b+s+p=37-2
1/3 s +s+2 s =35
1/3 s +s +2 s =35
10/3 s=35
s= 35*3/10
s= 10.5
b=1/3 s = 10.5/3 = 3.5
s= 1/2 p so p= 2s = 2( 10.5) = 21
10.5+3.5 + 21 = 35
Answer:
Last option
Step-by-step explanation:
Step 1: Distribute
x - 3/7 = 1
Step 2: Add 3/7 to both sides
x = 1 + 3/7
x = 10/7
Answer: x = -1 and y = 5
Step-by-step explanation:
7x + 3y = 8 ........................... equation 1
4x - y = - 9 ............................ equation 2
Solving the simultaneous linear equation by substitution method , make y the subject of the formula from equation 2 , we have
y = 4x + 9 ............................. equation 3
substitute y = 4x + 9 into equation 1 , we have;
7x + 3 ( 4x + 9 ) = 8
7x + 12x + 27 = 8
19x + 27 = 8
subtract 27 from both sides
19x = -19
divide through by 19
x = -1
substitute x = -1 into equation 3 , we have
y = 4 ( -1) + 9
y = -4 + 9
y = 5
Therefore :
x = -1 and y = 5
-(-z + 3) equals z - 3
5 = z - 3
z = 8
