Answer:

5,840 minutes

Step-by-step explanation:

Assuming there are 365 days in a year. If finn brushes his teeth 3 times , for 2 min each time then the time spent to brush his teeth in  a day

=3 * 2 minutes

= 6 minutes

If he flosses twice a day , for 5 minutes each time, then the time spent in a day to floss

= 2 * 5 minutes

= 10 minutes

Hence total time spent in a day brushing and flossing

= 6 + 10

= 16 minutes

Hence the time spent in  a year brushing and flossing

= 16 * 365

= 5,840 minutes

Answer:

x=3 y=4

Step-by-step explanation:

   -3x + 5y = 11

+   3x + y = 13

Add the equation (add the 5y and y. Then add the 11 and 13). The threes cancel each other out. It then leaves us with the equation:

6y = 24

Divide both sides by 6 to isolate the variable.

y=4.

Then just substitute the variable into any of the equations above. (I chose the equation on top)

-3x + 5(4) = 11

Then solve

-3x + 20 = 11 (then subtract 20 from both sides)

-3x = -9 (then divide both sides by -3)

x=3

Answer:

M'(0,-6),N'(2,0),P'(5,0) and Q'(7,-6)

Step-by-step explanation:

We are given that the vertices of quadrilateral MNPQ are M(-3,-2),N(-1,4),P(2,4) and Q(4,-2).

We have to translate the quadrilateral MNPQ using vector <3,-4>

The translate the coordinates of vertices (x,y) using the vector <a,b>  is given by the rule

[tex](x,y)\rightarrow (x+a,y+b)[/tex]

Using the rule

The new coordinates of M

[tex](-3,-2)\rightarrow (-3+3,-4-2)[/tex]

[tex](-3,-2)\rightarrow (0,-6)[/tex]

The new coordinates of N

[tex](-1,4)\rightarrow (2,0)[/tex]

The new coordinates of P

[tex](2,4)\rightarrow (5,0)[/tex]

The new coordinates of Q

[tex](4,-2)\rightarrow (7,-6)[/tex]

Hence, after translation the new vertices of quadrilateral are

M'(0,-6),N'(2,0),P'(5,0) and Q'(7,-6)

Answer:

Scale drawing is Larger

Step-by-step explanation:

There are 10mm in one cm, so scale drawing is larger than original by factor of 10.

Answer:

x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x+4x−68=34−8x

5x+4x+ −68=34+ −8x

(5x+4x)+(−68)=−8x+34(Combine like terms)

9x+−68=−8x+34

9x−68=−8x+34

Step 2: Add 8x to both sides.

9x −68+ 8x= −8x +34 +8x

17x −68 =34

Step 3: Add 68 to both sides.

17x −68 +68= 34 +68

17x=102

Step 4: Divide both sides by 17.

17x /17=  102/17

                                X=6   > final answer hope i could help :)

Step-by-step explanation:

Let's step through this line by line, looking for a spot where the friend could have made a mistake.

[tex]5x+4x-68=34-8x\\5x+4x=102-8x\\5x+4x+8x=102\\17x=102\\x=6[/tex]

So, where could the friend have made their mistake? The key here is the transition from step 1 to step 2. What if we had subtracted 68 instead of adding it?

[tex]5x+4x-68=34-8x\\5x+4x=-34-8x\\5x+4x+8x=-34\\17x=-34\\x=-2[/tex]

There it is. The friend's problem was that they had accidentally subtracted 68 to both sides when they should have added it.

Answer:

x = 43.5°

Step-by-step explanation:

The sum of the angles around a point = 360°

sum the angles and equate to 360

x + x + 72 + 111 + 90= 360

2x + 273° = 360° ( subtract 273° from both sides )

2x = 87° ( divide both sides by 2 )

x = 43.5°

Answer:

Sum of the angles around a given point is 360°.

[tex]x + x + 72 + 90 + 111 =360 \\ 2x + 273 = 360 \\2x = 360 - 273 \\ 2x = 87 \\ x = \frac{87}{2} \\ \boxed{x = 43.5°}✓[/tex]

Answer:

140

Step-by-step explanation:

5 times 4 is 20 which is the amount of browiners 20 times 7 is 140

Answer:

140$

Step-by-step explanation:

muliplication

4x5=20

20x7=140

1. (bh)/2 or (4 x 3)/2 = 6

2. (8 x 12)/2 = 48

3. (11.25 x 15.6)/2 = 87.75

4. (9 x 10)/2 = 45

Answer:

x = 4

Step-by-step explanation:

(7 + 2x) / 3 = 5

Cross product

7 + 2x = 5 * 3

7 + 2x = 15

Subtract 7 from both sides

2x = 15 - 7

2x = 8

Divide both sides by 2

x = 8/2

x = 4

Answer:

[tex]y=2x+7[/tex]

Step-by-step explanation:

All parallel lines have the same slope, so in slope intercept form, our line is going to look like

[tex]y=2x+b[/tex]

To find b, we can plug in the x and y values from the given point (-2, 3) and solve:

[tex]3=2(-2)+b\\3=-4+b\\b=7[/tex]

So our equation becomes

[tex]y=2x+7[/tex]

If you need help understanding why you move the decimal places, you can ask in the comments. :).

(-5, -1) is not a solution to the equation 2y = 2x - 4.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

2y = 2x - 4 _____(1)

Ordered pair: (-5, -1)

Now,

(-5, -1) = (x, y)

Substitute in (1)

2y = 2x - 4

2 x (-1) = 2 x (-5) - 4

-2 = -10 - 4

-2 = -14

This is not true.

Thus,

(-5, -1) is not a solution.
