Yes, because if you were to figure out what x= you would get 15. Try any other numbers, and they do not work
6x+2=5x+17
6x=5x+15
X=15
Answer:
The answer is B
Step-by-step explanation:
1. 2.50 x 2 is $5
2. 2.50 x 4 is $10
3. 2.50 x 3 is $7.50
4. 5 + 10 + 7.50 is 22.50 so you know the total should be 22.50.
5. It cant be A because 2.50 x 2 is 5 then timesing that by four would make 20 and then by 3 that would make $60 not $22.50
6. It is B because 2 + 4 + 3 is 9, 9x2.50 is 22.50
Answer:
$4
Step-by-step explanation:
Let amount from Maria be x
Maggie receives 1/5 x hence remainder is x-1/5 x=4/5x
Journi receives 3/8 of 4/5x=3/8 *4/5x=3/10x
Total by Maggie and Journi is 1/5x +3/10x=1/2x
Remainder is x-1/2x=1/2x
If Terrence receives the rest which is 1/2x to represent $10 then x=$10*2=$20
Amount Maggie receives is 1/5*$20=$4
Answer:
yes
Step-by-step explanation:
m=16
Answer:
Step-by-step explanation:
A dependent variable in an expression is one whose value can be determined only when the value of other variable (i.e independent) is known.
A. The cost at the fitness center depends on the number of months (x).
The cost is the dependent variable, and number of months (x) is the independent variable.
f(x) = 100 + 40x
Example, the cost paid for 12 months can be determined as;
f(12) = 100 + 40(12)
= 100 + 480
= 580
Thus, $580 would be paid for 12 months at the fitness center.
B. The lettuce is sold at $1.69 per pound. The cost depends on the number of pounds of lettuce bought.
The cost is the dependent variable, while the number of pounds of lettuce (x) bought is the independent variable.
So that;
f(x) = 1.69x
The cost of 10 pounds of lettuce can be determined as;
f(x) = 1.69(10)
= 16.9
Thus, the cost of 10 lb of lettuce is $16.90.
