Answer:

116.1

Step-by-step explanation:

If you round each decimal to the nearest tenth it would be 26.7 + 89.4 because you round up if it is 6 and above and round down for 5 and below. The rest is just simple addition.

(-0.75+6)-1(2.5x+-1.9

fenix001 [56]

Simplifying

(0.75x + 6) + -1(2.5x + -1.9) = 0

Reorder the terms:

(6 + 0.75x) + -1(2.5x + -1.9) = 0

Remove parenthesis around (6 + 0.75x)

6 + 0.75x + -1(2.5x + -1.9) = 0

Reorder the terms:

6 + 0.75x + -1(-1.9 + 2.5x) = 0

6 + 0.75x + (-1.9 * -1 + 2.5x * -1) = 0

6 + 0.75x + (1.9 + -2.5x) = 0

Reorder the terms:

6 + 1.9 + 0.75x + -2.5x = 0

Combine like terms: 6 + 1.9 = 7.9

7.9 + 0.75x + -2.5x = 0

Combine like terms: 0.75x + -2.5x = -1.75x

7.9 + -1.75x = 0

Solving

7.9 + -1.75x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7.9' to each side of the equation.

7.9 + -7.9 + -1.75x = 0 + -7.9

Combine like terms: 7.9 + -7.9 = 0.0

0.0 + -1.75x = 0 + -7.9

-1.75x = 0 + -7.9

Combine like terms: 0 + -7.9 = -7.9

-1.75x = -7.9

Divide each side by '-1.75'.

x = 4.514285714

Simplifying

x = 4.514285714

PLEASE SOLVE!! DUE RIGHT NOW!!! WILL MARK BRAINLIEST IF ANSWERED AND CORRECT!!!!!

Step-by-step explanation:

a) The measure of angle 7 is also 47 degrees. We know this because angle 5 and angle 7 are vertical angles and vertical angles are always equal.

b and c) Since we know that a straight line has an angle of 180 degrees and that the sum of angle 5 and angle 6 will add to this, we can use that to find the value of x like this:

$47+2x-5=180\\47-5+2x=180\\42+2x=180\\42-42+2x=180-42\\2x=138\\\frac{2x}{2} =\frac{138}{2} \\x=69$

Passes through (2,-1) and (1,-7)

Contact [7]

Answer:

y = 6x - 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (1, - 7)

m = $\frac{-7+1}{1-2}$ = $\frac{-6}{-1}$ = 6, thus

y = 6x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, - 7), then

- 7 = 6 + c ⇒ c = - 7 - 6 = - 13

y = 6x - 13 ← equation of line

The sum of two positive integers is 67. When the smaller integer is subtracted from twice the larger, the result is 38. Find the

bixtya [17]

Answer:

Step-by-step explanation:

x+y = 67

2x-y = 38

Add the equations together

3x = 108

x = 36

y = 67-x = 31
