If they all painted at the same rate the equation is this
mothers 8
daughters 12 at 220 sq ft
mothers 6
daughters 8 at 152 sq ft
220 +152 =372 divided by 34 (because they all painted at the same rate)=10.94 sq ft they each painted
Answer:
D. 3x + 1 < x + 3
Step-by-step explanation:
Assuming the number to be x
Three times a number = 3x
1 more than 3 times a number = 1 + 3x
The symbol for less than is = <
The sum of 3 and the same number = x + 3
After assembling the given data, the equation will be:
3x + 1 < x + 3
[The options given in the question are incorrect. The correct options will be:
A. 3x + 1 = x + 3
B. 3x − 1 = x + 3
C. 3x − 1 > x + 3
D. 3x + 1 < x + 3 ]
∴ Option D is the correct answer.
21 is a composite, because 21 x 1 = 21, and 7 x 3 = 21
61 is a prime, because it can only be multiplied by 1 to get 61
hope this helps
Answer:
12
Step-by-step explanation:
15/1.25 is 12
The answer is C. (7,1). You can add the two equations together and the y’s will cancel out since they are opposite signs and you are left with 2x=14. Then from there you can divide both sides by 2 and get x=7. Now at this point only one option has 7 as the x-value, but if you want to solve for y you can plug 7 I or one of the equations for x, ex: 7-y=6, and you would get y=1 as your answer which fits with option C.
