Answer:
900
Step-by-step explanation:
Assume x brick
X*(1／9+1/10）一 10=X/5
X(19/90-1/5)=10
X*(1/90)=10
X=900

Answer:
4
Step-by-step explanation:
The distributive property does not appear to be involved in this question.
Let n represent the number of Noah's pencils. Then Andrew's total is ...
3n +5 = 17
3n = 12 . . . . . subtract 5 from both sides
n = 4 . . . . . . divide both sides by 3
Noah has 4 pencils.
Solve the top equation for x and then substitute that into the bottom equation and solve for y:
Top equation: subtract 4 from both sides to get x = y - 4
Substitution and simplify:
y = 4(y - 4) - 10
y = 4y - 16 - 10
y = 4y - 26
-3y = -26
y = 26/3 or 8 1/3 or 8.333 (those are all the same but in different forms)
Answer:
14,334 actually that might not be the answer im just thinking that because the 4 is in the tenths place and ur rounding that u would make it into a whole number
Answer: a = 23 ft.
Reasoning:
The question asks for the value of the leg a, given the tangent of the opposite angle and the length of the adjacent-leg, b.
The ratio that relates the three parameters is:
tan(A) = opposite-leg / adjacent-leg = a / b = a / 23 ft
Solve for a, wich is the unknown:
a = 23ft * tan(A) = 23ft * 1.0 = 23 ft
Answer: 23 ft.
