As Thomas was checking his homework, he found a mistake in simplifying the expression below. Each step in the process should represent an expression equivalent to the original problem. Which step shows the error that Thomas found? Simplify: 7 – 2.4 + 3(0.82 = 2) Step 1: 7 -- 2.4 + 3(0.16 + 2) Step 2: 7 - 2.4 + 3(0.08) Step 3: 7 - 2.4 + 0.24 Step 4: 4.6 + 0.24 Step 5: 4.84

Through: (-3,-3) parallel to y= 7/3x+3

Grace is standing 18 feet from a lighthouse and kelly is standing 10 feet from grace. the angle that grace looks up to see the top of the lighthouse is 45°. the angle that kelly looks up to see the top of the lighthouse is y°. find the height, h, of the lighthouse. find the angle, rounded to the nearest tenth of a degree, in which kelly looks up to the top of the lighthouse. to the nearest tenth of a degree, find the value of x° . in two or more sentences, explain your calculations

Ihave like no idea how to do any of this !
