The value of a is 8.

Step-by-step explanation:

Vertical Angles:

The angles opposite each other when two lines cross.

They are always equal.

∠ 2(3a-7)° and ∠ (5a-6)° are vertical angles.Hence are equal.

So on Substituting we get

$2(3a-7)\°=(5a-6)\°$

Applying distributive property we get

$2\times 3a-2\times 7=5a-6\\6a-14=5a-6\\6a-5a=14-6\\\\\therefore a=8$

The value of a is 8

The Correct option is A) 8

Answer:

hmmmmmmmm, cool

well, here ya go

Step-by-step explanation:

0.7 is AKA 7/10, which is a little less than 3/4, AKA 0.75, so in between 3/4 and 1

1/3 is larger than 1/4 but smaller than 1/2, so prob somewhere in the middle of those two.

8/7, since the numerator is larger than the denominator, is larger than 1 by 1/7, so goes right in front of 1.

0.4, AKA 4/10, is a little less than 1/2, AKA 0.5, but larger than 1/3, AKA 0.333333333(goes on forever) so it goes in the middle of those

0.125, AKA 1/8, is the smallest of the bunch, and it's half of 1/4, AKA 0.25. That means its dead last, half between 1/4 and 0.

5/6 is the largest, around 8.333333(more foreverness)/10, which is larger than 3/4, AKA 0.75, so it goes between that and 1.

So, for your final answer:

0---0.125---1/4---1/3---0.4---1/2---0.7---3/4---5/6---1---8/7

I am not sure if thats what your structure for the question is, so I hope that that order helps. i could also put it in all decimals if it helps, or all fractions, so let me know in the comments.

Complete 6,7 for 5-8 points.

Answer:

Step-by-step explanation:

6)Let the number be x

Product of a number and -4 = x * -4 = -4x

Product of a number and -4 increase by 3 : -4x + 3

-4x +3 = 9

Subtract 3 from both sides

-4x + 3 - 3 = 9 - 3

-4x = 6

Divide both sides by (-4)

-4x/-4 = 6/-4

x = -3/2

x = -1 1/2

7)Let the number be x

$\frac{x}{6}-9=11\\\\$

Add 9 to both sides

$\frac{x}{6}-9+9=11+9\\\\\frac{x}{6}=20\\$

Multiply both sides with 6

$\frac{x}{6}*6=20*6\\\\$

x = 120
