(a)
So here's the information we know:
Tanya bought 3 items
Tony bought 4 items
Tony's items were all 2.50 less than Tanya's
So, our equation should look like this:
3x = 4(x - 2.25)
(b)
3x = 4(x - 2.25)
3x = 4x - 9
-x = -9
x = 9
Tanya spent = 9 (x)
Tony spent = 6.75 (x - 2.25)
(c)
3(9) = 4((9) - 2.25)
27 = 36 - 9
27 = 27
or
Tanya: 3x = 3 (9) = 27
Tony: 4( x - 2.25) = 4(9-2.25) = 4(6.75) = 27
(d)
We can conclude that Tanya bought 3 items with a cost of $9 each, and Tony bought 4 items with a cost of $6.75 each. Both Tanya and Tony spent a total of $27.
Answer:
answer C
Step-by-step explanation:
ive done it before
CD = x
BC = y
AB = 85
BD = BC+CD = y+x
tan(angle) = opposite/adjacent
tan(28) = BC/AB
tan(28) = y/85
85*tan(28) = y
y = 85*tan(28)
y = 45.1953016912257
tan(angle) = opposite/adjacent
tan(31) = BD/AB
tan(31) = (y+x)/85
tan(31) = (45.1953016912257+x)/85
85*tan(31) = 45.1953016912257+x
51.0731526173427 = 45.1953016912257+x
51.0731526173427-45.1953016912257 = 45.1953016912257+x-45.1953016912257
5.877850926117 = x
x = 5.877850926117
So CD is roughly 5.877850926117 meters
Answer:
6/25
Step-by-step explanation:
all you need to do is to look for common factors of both the numerator and the denominator and you keep on breaking it down
23.7%, all you got to do is move the decimal to the right twice
