the answer is -175. I hope that helped
Answer:
x > 23
Step-by-step explanation:
5x – 1 < 7x - 47
Add 1 to -47, you get -46.
5x < 7x - 46
Subtract 7x from 5x.
-2x < -46
Multiply both sides to reverse the inequality.
2x > 46
Divide both sides by 2.
x > 23
<h3>The solution is (x, y) = (-2, 3)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
4x + 5y = 7 ------ eqn 1
3x -2y = -12 ------- eqn 2
Multiply eqn 1 by 2
8x + 10y = 14 ------ eqn 3
Multiply eqn 2 by 5
15x - 10y = -60 ------- eqn 4
Add eqn 3 and eqn 4
8x + 10y = 14
15x - 10y = -60
( + ) -------------
23x = -46
<h3>x = -2</h3>
Substitute x = -2 in eqn 1
4(-2) + 5y = 7
-8 + 5y = 7
5y = 15
<h3>y = 3</h3>
Thus the solution is (x, y) = (-2, 3)
The formula for the area of a rhombus is s^2=A. Plug in and solve:
s^2=25
<em>*Take the square root of both sides*</em>
s=5
Hope this helps!!
