Answer:

  4, 5, 6

Step-by-step explanation:

Let x represent the middle one. Then the sum of the first two is ...

  (x -1) +x

And we want that to be 3 more than the third:

  (x -1) +x = (x +1) +3

  2x = x +5 . . . . . . . . . add 1, simplify

  x = 5 . . . . . . . . . . . . . subtract x

Since 5 is the middle integer, the three integers are ...

  4, 5, 6

Answer:

y=7x

Step-by-step explanation:

When finding the slope intercept form using 2 points, we do the following.

y=mx+b (Slope intercept from)

y=7x+b (7 is slope)

Substitute the point

7=7(1)+b

7=7+b

b=0

y=7x

The slope intercept equation is y = 7x

===========================================================

Explanation:

Recall that for y = a| x-h | + k, the vertex is (h,k).

Since all of the answer choices have a > 0, this means all of the vertexes are the lowest point for each absolute value graph.

Consequently it tells us the lowest possible y value.

Choices A, C and D indicate that getting y = -5 is impossible. For instance, if y = 2 is the smallest, then there's no way to get y = -5. I recommend making a number line.

The only thing left is choice B. If we plug in y = -5 then we get...

y = |x-2| - 6

-5 = |x-2| - 6

-5+6 = |x-2|

|x-2| = 1

x-2 = 1 or x-2 = -1

x = 1+2 or x = -1+2

x = 3 or x = 1

Plugging either of those x values into y = |x-2| - 6 leads to y = -5

You could try solving something like -5 = |x-6| + 2 for x, but you'll find that it has no solutions.

As another alternative, you can graph each answer choice. Then see which one intersects the horizontal line y = -5. You should see that only y = |x-2| - 6 does so.

Answer:

2n + 4

n = 12

Step-by-step explanation:

Given that :

Initial :

Dai has four more cards than twice the number that Maura has.

Maura's initial card = n

Dai's initial card = 2n + 4

B.)

If Dai must give Maura 8 cards, so they have equal amount

Dai's initial card - 8 = Maura's initial card + 8

2n + 4 - 8 = n + 8

2n - 4 = n + 8

2n - n = 8 + 4

n = 12

Answer:

The answer is 36 adults and 88 children.

Step-by-step explanation:

The two equations are:

x+y=124 and 5x+3y=444

Using substitution method:

5x+3(124+x)=444

5x+372-3x=444

2x=72

x=36

5(36)+3y=444

180+3y=444

3y=264

y=88

Answer: x = 1/5 and y= -7/5

Step-by-step explanation: Let's solve your system by elimination.

Multiply the first equation by -3,and multiply the second equation by 1.

-3 (x - 2y = 3)

1 (3x - y = 2)

Becomes:

-3x + 6y = -9

3x -y = 2

Add these equations to eliminate x:

5y = -7

Then solve 5y = -7

5y/7 = -7/5

y = -7/5

Now that we‘ve found y, let’s plug it back in and solve for x.

Write down an original equation:

x - 2y = 3

Answer:

The number of syringe filled with water that would be needed to fill the semi-sphere is approximately 8.714 syringes

Step-by-step explanation:

The height of the syringe = 6.8 cm

The diameter of the syringe = 2.37 cm

The circumference of the hemisphere = 31.4 cm

Let r represent the radius of the hemisphere, we have;

2·π·r = 31.4 cm

r = 31.4/(2 × π) ≈ 4.9975 cm

The volume of the hemisphere = 2/3 × π × r³ = 2/3 × π × (31.4/(2 × π))³ ≈ 261.4 cm³

The volume of the syringe = π × d²/4 × h = π × 2.37²/4 × 6.8 ≈ 29.998 cm³

The number of syringe filled with water that would be needed to fill the semi-sphere = (The volume of the hemisphere)/(The volume of the syringe)

Therefore;

The number of syringe filled with water that would be needed to fill the semi-sphere = 261.4 cm³/(29.998 cm³) ≈ 8.714 syringes.

The value of the given expression 7) (-7) + (-10) – 5 +2 is -20, 8) (-9) + 4 + (-8) – (-7) is -6, 9) (-6) – (2 x 4) – (-1) is -11, 10) (-8) + (-4 ÷ -4) – 8 is -15.

BODMAS stands for B- bracket, O- order, D-division, M-multiplication, A- addition, S- subtraction. We use this rule when there is more than one operation are present in the mathematical expression.

7)  (-7) + (-10) – 5 +2

here, we will use the BODMAS rule, the addition and subtraction will go from left to right.

= -7 -10 -5 + 2

= -17 -5 + 2

= -22 + 2

= -20

8) (-9) + 4 + (-8) – (-7)

=  -9 +4 -8 +7

= -5 -8 +7

= -13 + 7

= -6

9) (-6) – (2 x 4) – (-1)

= -6 - 8 +1

= -12 + 1

= -11

10) (-8) + (-4 ÷ -4) – 8

= -8 -4/ (-4) - 8

= -8 +1 -8

= -7 -8

= -15

Therefore, the value of the given expression 7) (-7) + (-10) – 5 +2 is -20, 8) (-9) + 4 + (-8) – (-7) is -6, 9) (-6) – (2 x 4) – (-1) is -11, 10) (-8) + (-4 ÷ -4) – 8 is -15.
