1 1/15 is the anwser

first we put in improper fraction 3 2/5 its 17/5 for 1 2/3 is 5/3

first find the common denominator which is 15 so like this:

3 6 9 12 15

5 10 15

the common denominator is 15 now we have to multiply the numerator by how many time we did to the bottom so now are new number are

51/15 -20/15

=31 15

now make it to a proper fraction and 1 1/15 is the anwser

have a good day have any question just ask in the comments also look at this is would help also if you have question please ask away

Ne4ueva [31]

A) x+y+z=23
B) y+z=14
C) z=9
Since z = 9 then
A) x + y = 14
B) y = 5
A) x + y+ z=23
A) x + 5 + 9 = 23
A) x = 9

Solve the system of equations.

Alenkasestr [34]

Step-by-step explanation:

Step 1: Substitute x from the second equation into the second one

$2x - 9y = 14$

$2(-6y + 7) - 9y = 14$

$(2 * -6y) + (2 * 7) - 9y = 14$

$-12y + 14 - 9y = 14$

$-21y +14 - 14 = 14 - 14$

$-21y/-21 = 0 / -21$

$y = 0$

Step 2: Substitute y into the second equation

$x = -6y + 7$

$x = -6(0) + 7$

$x = 0 + 7$

$x = 7$

Answer: $x = 7, y = 0$

The area of a rectangle is 1,036 cm and its length is 74 cm.

Nikitich [7]

Answer:

(i) Breadth = 14 cm

(ii) Perimeter = 176 cm

Step-by-step explanation:

Given,

Area of a rectangle = $1036$ cm²

Length = $74$ cm

(i) Breadth = ?

We know that, Area of a rectangle = length × breadth.

Then,

$1036 = 74 \times Breadth\\1036 \div 74 = Breadth\\\boxed{\bf\:14 \:cm = Breadth }$

(ii) Perimeter of a rectangle = 2 (length + breadth)

Then,

$Perimeter = 2(74 + 14)\\Perimeter = 2(88)\\\boxed{\bf\: Perimeter = 176 \: cm}$

$\rule{150pt}{2pt}$

Round to the nearest tenth wa hit is the perimeter of the triangle

klio [65]

Answer:

D. 11.8 cm

Step-by-step explanation:

This triangle is a 30°-60°-90° triangle. There is a shortcut to find the lengths of the sides of a 30°-60°-90° triangle. The longest side is the hypotenuse. The longest side is double the shortest side or, the shortest side is half the longest side. Here the longest side is 5, so the short leg (shortest side) is 2.5

The other shortcut is that the longer leg is the

short leg×sqroot3

Here, the short leg is 2.5, so the long leg is 2.5×sqroot3

Perimeter is all the sides added together.

5 + 2.5+ 2.5×sqrt3

Do the times first.

5 + 2.5 + 4.3

= 11.8
