The triangles are similar. Set the two triangle's measurements equal to each other
8/10 = (x - 1)/(x + 2)
Cross multiply
8(x+ 2) = 10(x - 1)
Distribute the numbers
8(x) = 8x
8(2) = 16
10(x) = 10x
10(-1) = -10
8x + 16 = 10x - 10
Isolate the x. Subtract 16 from both sides, and 10x from both sides
8x (-10x) + 16 (-16) = 10x (-10x) - 10 (-16)
8x - 10x = -10 - 16
Simplify. Combine like terms
-2x = -26
Isolate the x. Divide -2 from both sides
-2x/-2 = -26/-2
x = -26/-2
x = 13
13 is your answer for x
hope this helps
Answer:
1 1/12 ft
Step-by-step explanation:
12 inch per foot
13in - 12in = 1 in
1 in left over
1 1/12
3.4x - 7.2 = 5.8x + 24
3.4 - 5.8x = 24 + 7.2
-2.4x = 31.2
-2.4x / -2.4 = 31.2 / -2.4
x = -13
Answer:
1/4
Step-by-step explanation:
Favorable events/total events
favorable: 1 black counter
total: 1+3=4
0.50c, as it's $0.50 per cup and c represents the number of cups sold. When you have a variable (letter like in this case, which is c) you always multiply.
And for 1b you're going to be doing $127.50 divided by $0.50
Let me know if this makes sense
