2 x = 72

4 n = 7.5

6 no solution (the variable cancelled itself out)

8 no solution

10 x = 43

12 y=-5.83-x

14 <em>(P-2l)/2 = w</em>

16 Your team's score was 85 (because you scored 13 more points than the other team and 72 + 13 = 85).

18 The other scientist had the greater temperature (950 C > 1725 F), since 950 C = 1742 F

A system of linear equations is given as x + 3y = 36 and 4x + 5y = 9. Which of the following is a possible first step when solvi
Nikitich [7]

Answer:

Rewrite the first equation as x = 36 – 3y.

Step-by-step explanation:

x + 3y = 36 (1)

4x + 5y = 9 (2)

Using substitution method

From (1)

x = 36 - 3y

Substitute x = 36 - 3y into (2)

4x + 5y = 9

4(36 - 3y) + 5y = 9

144 - 12y + 5y = 9

- 12y + 5y = 9 - 144

-7y = -135

y = -135 / -7

y = 19.3

There is an error with the second equation, 4x + 5y can not be equal to 9

Nevertheless, the first step when solving by substitution is:

Rewrite the first equation as

x = 36 – 3y.

Tanzania [10]
The appropriate response is the third one. A Cartesian organize framework is an arrange framework that determines each point exceptionally in a plane by a couple of numerical directions, which are the marked separations to the point from two settled opposite coordinated lines, measured in a similar unit of length. Each reference line is known as an organize pivot or only hub of the framework, and the point where they meet is its birthplace, as a rule at requested combine (0, 0).

Trying to help my daughter can't figure this out.
Anvisha [2.4K]

Answer:

width equals 16

length = 20

Step-by-step explanation:

Hello there!

we know that the perimeter is 72 m

and the width is 4 m less then the length

perimeter is 2w+2l

w=width and l = length

72 + (2x-4) = 72+8 = 80

80 / 4 (because there are 4 values, w, w, l, l ) = 20

so now...

20 - 4 = w

16 = w

and 20 = l

16+16 = 32

20+20 = 40

32+40 = 72
