Answer:

-1.76

Step-by-step explanation:

-2 is equal to -2, so it works (greater or less than -2)

-2.45 is less than -2, so it works

-8 is less than -2, so it works

-1.75 is greater than -2, so it doesn't work

What is the solution to 4 (m-3) + 19 = 8 (2m + 3) + 7?

Flauer [41]

Answer:

x=-2

Step-by-step explanation:

Let m=x

$4(x-3)+19=8(2x+3)+7\\$

Expand the parentheses:

$4x-12+19=16x+24+7\\4x+7=16x+31\\-31+7=16x-4x\\-24=12x\\x=-2$

Anja is creating a triangle using 3 straws. The 2 shorter straws have lengths of 20cm and 21cm. How long, in centimeters, should

Bezzdna [24]

Answer:

The answer is 29 cm.

Step-by-step explanation:

The side we are looking for is the longest side of the right triangle, called a hypotenuse.

To find it, we first have to square 20, which equals 400. Then, square 21, which equals 441. Next, add 400 and 441 to make 841, then find the square root of 841, which is 29.

I hope this helped! :-)

5x+4y=16 -2x-4y=-4 <br>Show your step by step process.<br>Solve the system of linear equations.

slava [35]

Answer:

x=1 and y= 5 $\frac{1}{4}$

Step-by-step explanation:

To solve this, lets take the first equation and find the x value.

Because it is ordered in standard form, we need to convert to slope-intercept form, and isolate the y.

5x+4y=16

-5x -5x

4y=-5x+16

÷4 ÷4 ÷4

y= $\frac{-5}{4}$ +4

y=-1 $\frac{1}{4}$ +4

y= 5 $\frac{1}{4}$

Now that we have the y value, we can use this to find the x value by inserting it into either equation, since they both have y values in them. Going with the first one again, lets try it:

5x+4( $\frac{-5}{4}$ +4)=16

5x-5+16=16

5x+11=16

-11 -11

5x=5

÷5 ÷5

x=1 and y= 5 $\frac{1}{4}$
