Answer:
4 + 3n
Step-by-step explanation:
Number of seed planed in his garden = 4
Let the Number of seed planted in each neighbor's garden = n
Number of neighbors he has = 3
The total number of seeds planted can be represented by the equation :
Number of seeds planted in his garden + (number of neighbors * number of seeds planted in each neighbors garden)
4 + 3n
Answer:
x = -8, y = 6
Step-by-step explanation:
x + 2y = 4 ------(1)
x + y = - 2
y = - x - 2 ----------(2)
Substitute y in (1)
x + 2(- x - 2) = 4
x - 2x - 4 = 4
- x = 4 + 4
x = -8
Substitute x in (2)
y = - (- 8) - 2 = 8 - 2 = 6
A)4*16
because 4*3•4*4•4*9
you have to add the exponents
3+4+9=16
keep the number
so 4*16 is the answer
Answer:
The point (2,12) is not a solution of the system
see the explanation
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by elimination
Adds equation A and equation B
Find the value of y
substitute the value of x in the equation A
The solution of the system is the point (-2,-8)
The system has only one solution, because the intersection point both lines is only one point
therefore
The point (2,12) is not a solution of the system
Answer:
2) 62.5 wpm
3) 12.7 miles per gallon
4)18 commercials per hour
5) 22.9 ounces per dollar
Step-by-step explanation:
2) 500 words / 8 minutes = 62.5 words per 1 minute
3) 216 miles / 17 gallons = 12.7 miles per gallon
4) 36 commercials / 2 hours = 18 commercials per hour
5) 64 oz / $2.79 = 22.9 oz per $1
