Answer:
The two integers are -34,-33
Step-by-step explanation:
x 1st integer
x+1 2nd integer
The sum is -67
x+x+1 = -67
Combine like terms
2x+1 = -67
Subtract 1 from each side
2x+1-1 = -67-1
2x= -68
Divide by 2
2x/2 = -68/2
x = -34
x+1 = -34+1 = -33
25% of 60is 15
70% of 30 is 21
What % Is 15 of 50= 7.5
15% of 50 is 7.5
15% of 40 is 6
40% of 30 is 12
40% of 50 is 20
The system of equation is y = 300 + 3x and y = 250 + 5x and the number of visits is 25
<h3>The system of equations </h3>
The given parameters are:
<u>Jim's Gym</u>
- Initial fee = $300
- Charges = $3 per visit
<u>Sally's Salon</u>
- Initial fee = $250
- Charges = $5 per visit
The equation is calculated as:
Total (y) = Initial * Charges * Number of visits (x)
So, the system of equation is
y = 300 + 3x
y = 250 + 5x
<h3>Number of visits before the plans are equal</h3>
We have:
y = 300 + 3x
y = 250 + 5x
Substitute y = 300 + 3x in y = 250 + 5x
300 + 3x = 250 + 5x
Evaluate the like terms
-2x = -50
Divide by -2
x= 25
Hence, the number of visits is 25

Answer:
4 cm
Step-by-step explanation:
- PQ = 8 cm
- QR = 10 cm
- Height corresponding to PQ = 5 cm
- Height corresponding QR = x
The area of parallelogram is equal to product of its base and height
It can be expressed as
and
Comparing them we get
