Answer:
1. x = 30
REC = 130
Step-by-step explanation:
2x + 70 = 4x + 10
60 = 2x
x = 30
you try the others
Good luck :D
Answer: 0.75
Step-by-step explanation:
A survey of 364 children aged 19-36 months found that 91 liked to eat potato chips.
Total children surveyed= 364
Those that like to eat potato chips= 91
Those that don't like to eat potato chips= 364 - 91 = 273
Probability that the child chosen doesn't like to eat potato chips will be children that don't like to eat potato chips divided by total number of children surveyed.
= 273/364
= 0.75
Answer:
<u>infinitely many solutions</u>
Step-by-step explanation:
The system of equations :
- 3x + 2y = 7
- -4.5x - 3y = -10.5
Multiplying Equation 1 times 3 and Equation 2 times 2 :
- 9x + 6y = 21
- -9x - 6y = -21
Putting the equations in standard form after simplifying :
- 6y = -9x + 21 ⇒ <u>y = -1.5x + 3.5</u>
- -6y = 9x - 21 ⇒ <u>y = -1.5x + 3.5</u>
<u />
As both equations are the same, the system will have <u>infinitely many solutions</u>.
