Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week.
Let y be the number of strength-training exercises per week.
Let x be the number of aerobic exercises per week.
For the beginner plan, the equation would be gotten as;
15y + 20x = 90 ------(eq 1)
The equation to represent the advanced plan would be;
20y + 30x = 130 -------(eq 2)
Multiply both sides of eq 1 by 4 to get:
60y + 80x = 360 ------(eq 3)
Multiply both sides of eq 2 by 3 to get:
60y + 90x = 390 ------(eq 4)
Subtract eq(3) from eq(4) we get:
10x = 30
Thus; x = 3
Then; 15y + 20(3) = 90
15y = 30
y = 2
Thus, the correct statement is:
"Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week."

Equivalent rational numbers are generated by multiplying both the numerator and denominator by the same nonzero integer. These were calculated for -6/4, -4/12, and -12/10. The given numbers were then graphed on a number line and ordered from least to greatest.
For the first part of the question, equivalent rational numbers can be generated by multiplying both numerator and denominator by the same nonzero integer.
Therefore, equivalent rational numbers for -6/4 are: -12/8, -9/6, and -3/2. For -4/12, we have: -8/24, -2/6, and -1/3. For -12/10, we have: -24/20, -6/5, and -3/2.5.
The second part involves graphing the given numbers on a number line and then ordering them. The order from least to greatest would be: -9/5, -3.2, -3, 13/10, 2.5, and 4.

Answer:
Step-by-step explanation:
The area of a circle is the number of square units inside that circle. If each square in the circle to the left has an area of 1 cm2, you could count the total number of squares to get the area of this circle and the formula to find the area of a circle is
A.22 – 14x
B.22 – 6x
C.22 + 6x
D.11x – 5x
