Assuming that angle a is the smaller angle, angle A measures 30 degrees

Hope it helps!! :)

Answer:

Step-by-step explanation:

Summation means that you are adding together all the numbers that result from putting in the numbers 5-11 for i:

(-7 - 6(5)) + (-7 - 6(6)) + (-7 - 6(7)) + ( -7 - 6(8)) + ( -7 - 6(9)) + ( -7 - 6(10)) + ( -7 - 6(11)) which gives you the numbers:

-37 + -43 + -49 + -55 + -61 + -67 + -73 = -385

What quantity of a 50% acid solution must be mixed with a 20% solution to produce 600 mL of a 45% solution?

Naddika [18.5K]

Answer:

400 mL

Step-by-step explanation:

0.50x + 0.20(600-x) = 0.40*600

50x + 20*600 - 20x = 40*600

30x = 20*600

x = 20*20

x = 400 mL

ABSOLUTEEE VALUEEEE HELPP PLZ

Answer:

Last option; x < 2 and x > -1

Step-by-step explanation:

1. We know 2x − 1 < 3 and 2x − 1 > −3, so let's solve both of these inequalities.

2. (Solving for 1st condition)

Step 1: Add 1 to both sides.

$2x - 1 + 1 < 3 + 1$
$2x < 4$

Step 2: Divide both sides by 2.

$\frac{2x}{2} < \frac{4}{2}$
$x < 2$

3. (Solving for 2nd condition)

Step 1: Add 1 to both sides.

$2x - 1 + 1 > -3 + 1$
$2x > -2$

Step 2: Divide both sides by 2.

$\frac{2x}{2} > \frac{-2}{2}$
$x > -1$

4. Now, we know that the value of x is greater than -1 but less than 2, and we can represent it on a number line like this:

Help with 8th-grade middle school math show work

Answer:

So for the triangle, we have x = 25 and the angles 45-75-60.

So for the quadrilateral, we have x = 75 and the angles 70-110-75-105.

Step-by-step explanation:

For each of these problems, we can simply add the expressions of the angles given matched to the sum of the angles for the shape given below. Once we do this, we can solve for x, and then state the given measures of each angle of the shapes.

<u>For the triangle:</u>

60 + ( x + 20 ) + 3x = 180

60 + x + 20 + 3x = 180

60 + 20 + x + 3x = 180

80 + x ( 1 + 3 ) = 180

80 + x ( 4 ) = 180

80 + 4x = 180

4x = 100

x = 25

We have the given angles:

x + 20 ==> 25 + 20 ==> 45

3x ==> 3 (25) ==> 75

60

So for the triangle, we have the angles 45-75-60.

<u>For the quadrilateral:</u>

( x - 5 ) + ( x + 35 ) + x + 1.4x = 360

x - 5 + x + 35 + x + 1.4x = 360

35 - 5 + x + x + x + 1.4x = 360

30 + x ( 1 + 1 + 1 + 1.4 ) = 360

30 + x ( 4.4 ) = 360

30 + 4.4x = 360

4.4x = 330

x = 75

So, we have the given angles:

x - 5 ==> 75 - 5 ==> 70

x + 35 ==> 75 + 35 ==> 110

x ==> 75

1.4x ==> 1.4(75) ==> 105

So for the quadrilateral, we have the angles 70-110-75-105.

Cheers.
