Answer:

z<2

Step-by-step explanation:

-2(z + 5) + 20 > 6

Subtract 20 from each side

-2(z + 5) + 20 -20 > 6-20

-2(z + 5) > -14

Divide each side by -2 remembering  to flip the inequality

-2/ -2(z + 5) < -14/-2

z+5 < 7

Subtract 5 from each side

z+5-5 < 7-5

z<2

First you need to distribute
then you’d have -2z - 10 + 20 > 6
-2z + 10 > 6
-2z > 6 - 10
-2z > - 4
z < 2

Franco:
3x+2y=19
Caryl:
2x+4y=24

now use elimination

-2(3x+2y=19)
1(2x+4y=24)
=
-6x-4y=-38
2x+4y=24
add them together
which equals -4x=-14
divide both sides by -4
-4x/-4=-14/-4
x=7/2


we found x, so we subsitute it into the the original equation

3x+2y=19
3(7/2)2y=19
2y+21/2=19
-21/2 -21/2
2y=17/2
divide by 2 on both sides
2y/2= 17/2/2
y=17/4

so x= 7/2 and y= 17/4

What is the greatest common factor of 20x6y+40x4y2−10x5y5 ?
mestny [16]
The greatest common factor: 20x^6y 40x^4y^2 10x^5y^5 is 10x^4y.
20x^6y = 10x^4y*2x^2
40x^4y^2 = 10x^4y*4y
10x^5y^5 = 10x^4y*y^4

8' 4" − 2' 6" = ??' ??"
SCORPION-xisa [38]

Answer:

5' 10"

Step-by-step explanation:

We subtract by converting into one measurement. We will choose inches.

8'4"= 96"+4"=100" since 8' has 8(12) inches

2'6"=24+6=30" since 2' has 2(12) inches

Subtract.

100"-30"=70"

We convert back into feet and inches by dividing by 12.

70/12= 5' 10"
