Answer:
<h3>#1</h3>
<u>The system of equations:</u>
- 2x + 7y = -11
- 3x + 5y = -22
Solve by elimination.
<u>Triple the first equation, double the second one, subtract the second from the first and solve for y:</u>
- 3(2x + 7y) - 2(3x + 5y) = 3(-11) - 2(-22)
- 6x + 21y - 6x - 10y = -33 + 44
- 11y = 11
- y = 1
<u>Find x:</u>
- 2x + 7*1 = -11
- 2x = -11 - 7
- 2x = -18
- x = -9
<u>The solution is:</u>
<h3>#2</h3>
<u>Simplifying in steps:</u>
- 8u - 29 > -3(3 - 4u)
- 8u - 29 > - 9 + 12u
- 12u - 8u < -29 + 9
- 4u < -20
- u < -5

Answer:
95
because what is 95 times 10.8 if you multiply that you will get 1026
Also you get 95 by dividing 1026 by 10.8
Answer:
The probability of spinning an even number is 1:2, or 50 percent. The probability of rolling an odd number is also 1:2, or 50 percent.
Explanation:
On most number spinners, there are an equal number of odds and evens. This is the same for a dice, since the numbers range from 1-6; 3 odd numbers and 3 even numbers.
Area of square = 5 x 5 = 25
area of trapezoid = 1/2(2+5)(4) = 28/2 = 14
area of figure = 25 + 14 = 39
answer
39 in^2
