Solve for x if z+4/5=11

Mathematics
1 answer:
Ede4ka [16]3 years ago
3 0

Solve for z. Isolate the z. Note the equal sign. What you do to one side, you do to the other side.

Subtract 4/5 from both sides

z + 4/5 (-4/5) = 11 (-4/5)

z = 10 5/5 - 4/5

Simplify

z = 10 1/5

10 1/5 is your answer for z

hope this helps

Help I can not figure this out at all even my older kids tried
Semenov [28]
Don't repost because somebody will answer (probably)

we got some points
normally it is like
y=mx+b
find m and x
if we assume they are in a straight line
m is slope and b is y intercept
ok so we see the slope betwee (6,11) and (3,5) is 2
because slope between (x1,y1) and (x1,y1) is (y2-y1)/(x2-x1)

y=2x+b
if we solve for b we get
hmm
5=2(3)+b
5=6+b
-1=b

y=2x-1


so double x and minus 1 to get y
10*2=20, 20-1=19


23=2x-1
24=2x
12=x

the missing points are 19 on right side and 12 on left
rule is y=2x-1 or
2x-y=1

Which point slope form equations could be produced with the points (3,2) and (4,6)
Anika [276]

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of a line given two points first find the slope of the line and use the formula

y - y1 = m( x - x1) to find the Equation of the line using any of the points given

Slope of the line using points

(3,2) and (4,6) is

m =  \frac{6 - 2}{4 - 3}   =  \frac{4}{1}  = 4

So the equation of the line using point

( 3 , 2 ) and slope 4 is

<h3>y - 2 = 4( x - 3)</h3>

Hope this helps you

Can 12 cm 12 cm and 28 cm form a triangle
erastova [34]
Using the Theorem of Pythagoras (a² + b² = c²)

Put in the values:

12² + 12² = 28²
Is it correct? (solve)

Nope! Because 12² + 12² = 288, and the square root of 288 is about 17, not 28.

The answer is no, 12cm, 12cm, 28cm cannot form a triangle.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)
