Answer:
54
Step-by-step explanation:
3x -(7-x) = 29 remove the parens
3x - 7 + x = 29 simplify
4x -7 = 29 add 7 to both sides of the equation
4x = 36 divide by
x = 9
then 6x = 6 * 9 = 54
Answer:
Step-by-step explanation 10 + 2.50d = 850
David starts with $10 and each day he earns $2.50. The d represents a variable and can be any number.
To find d you must solve the equation.
10 + 2.50d = 850
2.50d = 840 (subtract 10 from 850)
d = 336 (divide 840 by 2.50)
It will take David 336 days to save $850.
Answer:
1063 ft
Step-by-step explanation:
For shadow problems, we assume the sun's rays are parallel, so the triangles formed are similar. That means the ratio of height to shadow length is the same for each object.
h/(580 ft) = (5.5 ft)/(3 ft)
h = (5.5 ft)(580/3) ≈ 1063 ft
The height of the monument is about 1063 feet.
