Answer:
(2,7) is not a solution to the given system of equations.
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.
83620 the 2 is in the 10s place and on 208 the 2 is in the 100s place so the 2 in 208 is 10 times bigger than the 2 in 83620 I hope i'm right sorry if your not
Answer:
The percentage is 1/2 * 2/5 = 1/5 = 20%.
Answer:
cost of bracelet = 25*.05 +4*.45
cost of bracelets = 2(25*.05 +4*.45)
Step-by-step explanation:
One bracelet
Supplies needed:
25 beads and 4 charms
Each bead costs .05 and each charm costs .45
Cost of bracelet = number of beads * cost per bead + number of charms * cost per charm
cost of bracelet = 25*.05 +4*.45
cost of bracelet = 1.2 +1.8
=3.00
To make 2 bracelets
Cost of bracelets =2*( number of beads * cost per bead + number of charms * cost per charm)
cost of bracelets =2*( 25*.05 +4*.45)
cost of bracelets=2( 1.2 +1.8)
cost of bracelets = 2*3
cost of bracelets = 6
