What's the answer to this math problem 3x+2/5 =7

1 answer:

5 0

3x+2/5=7

3x+2/5=35/5

3x=35/5-2/5

3x=33/5

x=(33/5)/3

x=(33/5)/(3/1)

x=(33/5)*(1/3)

x=33/15

x=30/15+3/15=2+1/5

x=2.2

Answer:

m <1 = 61

Step-by-step explanation:

We know that the angle adjacent to 130 is 50 degrees because linear angles are complementary.

Extending line t to make a triangle, we can find the angle adjacent to the angle labeled 111 ( and above it) is 69.

That makes the angle that touches line q 61 to finish the triangle

This angle and angle 1 are corresponding angles, so they are equal

<1 = 61

Solve the compound inequality for x and identify the graph of its solution. x + 7 < 3 or x - 52 -1 O A. Solution: x < -4 o

aleksley [76]

Answer:

D. x < -4 or x ≥ 4

Step-by-step explanation:

You can eliminate choices A and B because the graph and the inequalities do not agree.

You can eliminate choice C because the first inequality tells you ...

x < some value

That means the shading will be to the left of an open circle.

This is only shown in Choice D.

<em>Additional comment</em>

You can work multiple choice questions several different ways. I like to choose the simplest, which often means you do not actually need to work the problem. You only need to be able to identify ...

answers that are self-consistent
answers that are consistent with problem requirements
answers that are consistent with numerical and geometric facts

Here, we can eliminate incorrect answers by throwing out those that are not self-consistent and that are not consistent with the problem statement.

If we were to solve the inequalities, we would subtract 7 from both sides of the first one:

x +7 < 3

x < -4 . . . . . . subtract 7 from both sides

and we would add 5 to both sides of the second one:

x -5 ≥ -1

x ≥ 4 . . . . . . add 5 to both sides

If you write these inequalities so the symbols point left, you have ...

x < -4 or 4 ≤ x

This tells you shading is "outside" the segment between -4 and 4, and that there is an open-circle at x=-4. This is consistent with the number lines of choices B and D. However, these inequalities are <em>not consistent</em> with what is written in choice B.

Which is the best approximation for the measure of angle ABC?

qwelly [4]

Answer:

58.3°

Step-by-step explanation:

Missing Information:

In this question the diagram is missing Following are the attachment of diagram of the given question.

As we seen that the vertex c is making the right angle i,e 90° also there is an acute angle the Hypotenuse: 20 cm and the perpendicular is 10.5 cm

Now we have find the best approximation of the angle ABC used the cosx trigonometric function.

$cos\ x\ =\ \frac{perpendicular}{Hypotenuse} \\$
