Answer:

17

Step-by-step explanation:

Let's solve your equation step-by-step.

6x+78=180

Step 1: Subtract 78 from both sides.

6x+78−78=180−78

6x=102

Step 2: Divide both sides by 6

6x/6=102/6

x=17

Answer:

x = 17

Step-by-step explanation:

If you subsitute x in "2x" you get 34. If you subsitute x for "4x - 4" you get 64.

After subtracting 180 from 98 you get 82. Add up 34, 64, and 82 then you get 180.

Answer:

X = 44

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x=44

Step-by-step explanation:

First you add the all the x's.

4x+10-6=180

Then you subtract 6 from 10

4x+4=180

Next, you add subtract 4 from both sides.

4x=176

Divide by 4 and you get 44.

176/4

x=44

Answer:

leftmost empty cell: ⅓

rightmost empty cell: 3

Step-by-step explanation:

✔️If 2 pounds grapes cost $6, then x pounds of grapes cost $1.

Thus;

2 : 6 = x : 1

2/6 = x/1

Multiply both sides by

²/6 × 1 = x/1 × 1

²/6 = x

¹/3 = x

x = ⅓

✔️If 2 pounds grapes cost $6, then 1 pound of grapes cost $x.

Thus;

2 : 6 = 1 : x

²/6 = ¹/x

Cross multiply

2x = 6

Divide both sides by 2

2x/2 = ⁶/2

x = 3

Answer:

  ∠6 = ∠4 = 84°

  ∠5 = ∠3 = 96°

Step-by-step explanation:

Angle 4 and the marked angle (84°) are corresponding angles, so are congruent. Angles 4 and 6 are vertical angles, so are congruent.

  ∠6 = ∠4 = 84°

Angle 3 and the marked angle are a linear pair, so angle 3 is the supplement of 84°:

  ∠3 = 180° -84° = 96°

Angle 3 and angle 5 are alternate interior angles, so are congruent.

  ∠5 = ∠3 = 96°

Step-by-step explanation:

8 times would you expect to draw a blue marble.

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Given:

Total marbles = 10

Blue marbles=2

Number of times= 40

So, the number of times would you expect to draw a blue marble

=2/10 *40

=80/10

=8

Hence, 8 times would you expect to draw a blue marble.

Answer:

can you add the answers?

Step-by-step explanation:

Answer:

Start at -150, then add 3(-5), then add 122.2. -150 + 3(-5) + 122.2 = -45.3.

The answer is -45.3 feet depth. while minus sign shows the descend under the water with water surface as starting point.

Step-by-step explanation:

Initial depth of diver under the water =-150feet=−150feet

Diver descends 5 feet per minute for 3.5 minutes =3.5*(-5)=3.5∗(−5)

                                                                                =-17.5=−17.5

Note: minus sign shows that the diver is under the water.

Diver ascends =122.2feet=122.2feet

Now adding all the terms a below as a numerical expression.

Current Depth of Diver after he descends 5 feet for 3.5 minutes and ascend 122.2 feet after  =-150-17.5+122.2=−150−17.5+122.2

                           =45.3feet=45.3feet

By taking the initial depth of diver from which we add or subtract the changes made when he ascends or descends in the water to get the current depth.
