Answer:
Required system of equation is
4s+3c=26 and 5s+2c=29.
Step-by-step explanation:
Let cost of 1 sundaes = s
Let cost of 1 cone = c
Then statement "Marcus is treating his family to ice cream he buys 4 Sundaes and 3 cones for the total of $26", gives equation:
4s+3c=26...(i)
And statement "Brian also buy ice cream for his family his total is 29 for purchasing 2 cones and 5 Sundaes " gives equation:
5s+2c=29...(ii)
Hence required system of equation is
4s+3c=26 and 5s+2c=29.
Answer:
First you can substitute y with the value of it. So -3x=(4x+17)+4. Once you've found x plug in that value in -3x and solve for y.
So we know that Kenzi 15 bracelets a week. And the question is asking how long it takes to make 105 bracelets. So we divide the amount we want (105) by the amount he can make per week (15):
105 / 15 = 7
It takes Kenzi 7 weeks to make 105 bracelets.
Answer:
-21
Step-by-step explanation:
put in -3 where x is
-3^2 9
-9-12 = -21
2^9=512
There are 512 possible solutions
