Answer:
0.30715935334
Step-by-step explanation:
8/6 ÷ 13/3
1.33÷ 4.33
0.30715935334
Step-by-step explanation:
a. we simply subtract 3. from 2.
x + 2y + z = 15
- -3x + y + z = 2
--------------------------
4x + y 0 = 13
b. we multiply 3. by 3 and then subtract from 1.
2x - 4y + 3z = -7
- -9x + 3y + 3z = 6
-----------------------------
11x - 7y 0 = -13
c. we multiply the result of a. by 7, and then simply add a. and b., because the y terms have different signs already.
28x + 7y = 91
+ 11x - 7y = -13
--------------------------
39x 0 = 78
39x = 78
x = 2
d. we use this x = 2 in the result of a.
4×2 + y = 13
8 + y = 13
y = 5
e. using x = 2 and y = 5 in 2.
2 + 2×5 + z = 15
2 + 10 + z = 15
12 + z = 15
z = 3
the solution is therefore (2, 5, 3).
Answer:
1/6
Step-by-step explanation:
Rational numbers between two rational numbers:
- First find the Least Common Denominator for 2 and 3
- Then find equivalent fractions with the LCD.
LCD of 2 and 3 = 6


Answer:
The tree is 18ft tall
Explanation:
Shadow = Real
4ft = 6ft(man)
1ft = 1.5ft
Let tree = yft
12 = y
y = 12 × 1.5
= 18ft
