Use row operations to solve the system.
Aleks04 [339]

Answer:

x = 2, y = 7, z = 12

Step-by-step explanation:

x + y - z = -3 (1)

3x - y + z = 11 (2)

x - 4y + z = -14 (3)

add (1) and (2)

4x = 8 x = 2

add (1) and (3)

2x - 3y = -17

2(2) - 3y = -17

-3y = -17 - 4

-3y = -21

y = 7

Find z using any equation

x + y - z = -3

2 + 7 - z = -3

9 - z = -3

z = 12

Please help <br> The diagram shows a 5ft student standing near a tree
Novosadov [1.4K]

Answer:

25 ft

Step-by-step explanation:

The diagram shows two triangles that are similar.  Similar triangles have equal angles and sides that are proportional to each other.  Since the base of each triangle is given, we can find the proportion of the sides:

\frac{smaller}{larger}=\frac{8}{40}=\frac{1}{5}

Given the ratio of the smaller to larger triangle, we can set up a proportion to find the missing height of the larger triangle:

\frac{1}{5}=\frac{5}{x}, where 'x' represent the height of the tree

cross-multiply:  x = (5)(5) or 25 ft

What is the reciprocal of 6/5?<br> a. 12/10<br> b. 1 1/5<br> c. 1<br> d. 5/6
galina1969 [7]
<span>The reciprocal of a fraction is simply the reverse position of the original fraction, its numerator and denominator. It is represented by the formula of 1/number (fraction). To get the reciprocal of the number, divide one by the fractional number. You are given the number 6/5. So you have a numerator of 6 and a denominator of five. Simply swap them and you get the new numerator as 5 and the new denominator as 6. Or you can just divide 1/(6/5) then you will get 5/6. The answer is letter D.</span>

Vika [28.1K]

Answer:

22 ft

Step-by-step explanation:

Height of Susan/Length of shadow = Height of sculpture/Length of Shadow of sculpture

5.5 ft/4 ft = x/16ft

Cross Multiply

4 × x = 5.5 × 16

x = 5.5 × 16/4

x = 22 ft

The height of the sculpture is 22 ft
