QveST [7]

Answer:

x = 0.954

Step-by-step explanation:

We apply pythagorean to find x

(4-x)² = 1.2² + 2.8²

(4-x)² = 9.28

✓(4-x)² = ✓(9.28)²

4 - x = 3.046

- x = 3.046 - 4

- x = -0.954

x = 0.954

(Please heart and rate if you find it helpful, it's a motivation for me to help more people)

-4x+5(20/11)=-4<br><br> Please explain how to get x, thank u!
avanturin [10]

-4x + 5 \left(\dfrac{20}{11}\right) =-4\\\\\implies \dfrac{100}{11} = -4+4x\\\\\implies 100 = -44+44x\\\\\implies 44x = 100 +44 = 144\\\\\implies x = \dfrac{144}{44} = \dfrac{36}{11}
