Answer:
X = 20
Step-by-step explanation:
when you have an angle that looks like an X shape the angles opposite each other are always equal. knowing this we now know that angle 5x must equal 100
so just make X the subject of the formula and solve, like shown bellow



Answer:
(-2, -5)
Step-by-step explanation:
in a rectangle there will be 4 different numbers. Each number will have 2 spots. 2 numbers will have 2 x spots, and 2 numbers will have 2 y spots. we notice that our numbers are -2, -5, 3, and 4.
we see that -2 and 3 are our x values, and -5 and 4 are our y values.
-2 and -5 are the 2 numbers that have not been repeated, so the last corner's coordinates are (-2,-5)
-8x+8 because you simplify the like terms. So all the x’s and all the whole numbers
Answer:
50 mph, 62 mph
Step-by-step explanation:
Their total speed is found from ...
speed = distance/time
speed = (364 mi)/(3.25 h) = 112 mi/h
If s is the speed of the slower car, then ...
s + (s+12) = 112 . . . . . their total speed is 112 mph
2s = 100 . . . . . . . . . . simplify, subtract 12
s = 50 . . . . . . . the speed of the slower car
s+12 = 62 . . . . the speed of the faster car
