Answer:

360

Step-by-step explanation:

3/4a - 16 = 2/3a + 14 ⇒ collect like terms
3/4a - 2/3a = 14 + 16 ⇒ bring the fractions to same denominator
9/12a - 8/12a = 30 ⇒ simplify fraction
1/12a = 30 ⇒ multiply both sides by 12
a = 30*12
a = 360 ⇒ answer

Sorry I suck at math but PLEASE HELP solve these 3!!!

Leto [7]

Answer:

1. x = 10

2. x = 8

3. x = 7

Step-by-step explanation:

1. Sum of Angles in a triangle = 180

(6x + 3) + (5x - 7) + 74 = 180

11x - 4 + 74 = 180

11x + 70 = 180

Subtract 70 from both sides

11x = 110

Divide both sides by 11

x = 10

2. (8x + 1) + (7x + 14) + 45 = 180

15x + 15 + 45 = 180

15x + 60 = 180

Subtract 60 from both sides

15x = 120

Divide both sides by 15

x = 8

3. We first have to get the 3rd angle: 180 - Exterior angle = 3rd angle

180 - 118 = 62

Now we can find the value of x

10x + (6 + 6x) + 62 = 180

16x + 68 = 180

Subtract 68 from both sides

16x = 112

Divide both sides by 16

x = 7

What is an equation of the line that passes through the point ( 6 , − 2 ) (6,−2) and is perpendicular to the line 6 x + y = 2 6x

Diano4ka-milaya [45]

Answer:

An equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be:

$y=\frac{1}{6}x-3$

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept.

Given the line

6x+y=2

Simplifying the equation to write into the slope-intercept form

y = -6x+2

So, the slope = -6

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

Thus, the slope of the perpendicular line will be: -1/-6 = 1/6

Therefore, an equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be

$y-y_1=m\left(x-x_1\right)$

substituting the values m = 1/6 and the point (6, -2)

$y-\left(-2\right)=\frac{1}{6}\left(x-6\right)$

$y+2=\frac{1}{6}\left(x-6\right)$

subtract 2 from both sides

$y+2-2=\frac{1}{6}\left(x-6\right)-2$

$y=\frac{1}{6}x-3$

Therefore, an equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be:

$y=\frac{1}{6}x-3$

Each week. You make $10.00 but you spend $3.00 and save the rest. How much would you save in 8 weeks?

Marianna [84]

10*8=80
3*8=24
80-24=56
You would save $56.00 in 8 weeks

Chen uses mental math to find the sum of 326 and 24. She uses 320, 24, and one other number. What is the missing number?

Leto [7]

Wouldn't be 6? Because 320 is missing 6
