Type the integer that makes the following addition sentence true: 9 + what = 2

Answers

I believe the answer to be (-7)

Answer:

-7

Step-by-step explanation:

Step 1: Make an equation.

[tex]9 + x = 2[/tex]

Step 2: Subtract 9 from both sides.

[tex]9 + x - 9 = 2 - 9[/tex] [tex]x = -7[/tex]

Step 3: Check if solution is correct.

[tex]9 + (-7) = 2[/tex] [tex]9 - 7 = 2[/tex] [tex]2 = 2[/tex]

Therefore, the integer that makes the addition sentence true is -7.

A sloth crawled 6 cm in one second. What was its speed in km/h? (1 hr =
3600 s) (1 km = 100,000 cm)

Answers

Step-by-step explanation:

it was measured that the south crawled 6cm in 1 second.

that gets expressed by the ratio

6 cm/sec or formally correct 6/1 cm/sec.

to get that speed in km/h (kilometers per hour), we need to transform the denominator of that ratio to 1 hour.

the only way we can manipulate a fraction or ratio without changing its value is by multiplying numerator and denominator (top and bottom) by the same factor.

like x/y × 3/3 = 3x/3y.

the driver behind a question of this kind is again the denominator. we want the denominator to appear as 1 hour.

so, what do I need to multiply 1 second with to get 1 hour ?

the problem definition tells us : 3600, as there are 3600 seconds in 1 hour.

so, we need to multiply

6/1 × 3600/3600 = (6×3600)/3600 = 21600/3600 =

21600cm/1 hour.

and now, how many km are 21600 cm ?

1 km = 100000 cm

so,

21600cm = 21600/100000 km = 0.216 km

therefore, or full answer is

the sloth's speed was 0.216 km/h

Find the x and y intercepts

Answers

Answer:

x:(-1,0),(5,0)

y:(0,-2)

Answer:

see explanation

Step-by-step explanation:

The x- intercepts are where the graph crosses the x- axis

The graph crosses the x- axis at x = - 1 and x = 5 ← x- intercepts

The y- intercept is where the graph crosses the y- axis

The graph crosses the y- axis at - 2 ← y- intercept

Adult tickets to
the fall play cost $8 and student tickets cost $4. The drama class
sold 20 more adult tickets than student tickets to the fall play. If the class
collected $880 from
ticket sales, how many adult tickets were sold?
The drama class sold
adult tickets.
The solution is?

Answers

Substitution.
Adult tickets = A (cost $8)
student tickets = S (cost $4)

The drama class sold 20 more adult tickets than student tickets:
A = S + 20 (equation 1)

The class collected $880 from tickets:
8A + 4S = 880 (equation 2)

How many adult tickets were sold?
A = S + 20
8A + 4S = 880

we substitute the first equation into the second:
8(S+20) + 4S = 880
8S + 160 + 4S = 880
12S = 720
S = 60

Next we find the adult tickets by substituting back:
A = S + 20
A = 60 + 20
A = 80

Check our answer by substituting our answers in equation 2:
8A + 4S = 880 (equation 2)
8(80) + 4(60) = 880
640 + 240 = 880
880 = 880

Part A Write an expression to find size of the largest jellyfish. Represent the expression in meters as a product of two numbers in scientific notation.

Answers

Answer:

The expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.

Step-by-step explanation:

A jellyfish can be up to 1 × 108 times bigger than femtoplankton. Find the size of the largest jellyfish by multiplying the size of a femtoplankton by 1 × 108 times.

The size of a femtoplankton is 2 × 10-8 meter. That means the expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.

2a+4=3 what is the value of a???????

Answers

Hey there!

2a + 4 = 3

ADD 4 to BOTH SIDES

2a + 4 - 4 = 3 - 4

CANCEL out: 4 - 4 because that gives you 1

KEEP: 3 - 4 because it helps solve for the a-value

2a = 3 - 4

3 - 4 = -1

2a = -1

DIVIDE 2 to BOTH SIDES

2a/2 = -1/2

CANCEL out: 2/2 because it gives you 1

KEEP: -1/2 because it gives you the value of the a-value

a = -1/2

SIMPLIFY IT!

Therefore, your answer is: a = -1/2

Simone applied the distributive property using the greatest common factor to determine the expression that is equivalent to 24 + 56. Her work is shown below.

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56

24 + 56 = 8 (4 + 7)

What statement best describes Simone’s error?
Simone did not use the correct factors for 24 in the equation.
Simone did not use the correct factors for 56 in the equation.
Simone did not use the greatest common factor in the equation.
Simone did not use the correct operations in the equation.

Answers

For this case we have the following expression:
24 + 56
The factors of the numbers are:
24: 1, 2, 3, 4, 6, 8, 12, 24
56: 1, 2, 4, 7, 8, 14, 28, 56
So, factoring we have:
24 + 56 = 8 (3 + 7)
Simone wrote:
24 + 56 = 8 (4 + 7)
Therefore his error is:
Simone did not use the correct factors for 24 in the equation

Solve the system by substitution.
−5x+2y=14
y=3x+2

Answers

Answer: x = 10; y = 32

Step-by-step explanation:

let −5x+2y=14 be [1]

& y=3x+2 be [2]

Finding the value of x

By substituting y in [2] for y in [1]

⇒ −5x + 2(3x+2) = 14 [expand the bracket]

⇒ -5x + 6x + 4 = 14 [subract 4 from both sides and simplify]

⇒ x = 10

Finding the value of y

Since x =10, we can substitute value of x into [2]

⇒ y = 3(10) + 2

⇒ y = 32

Complete the statement. Round to the nearest hundredth if necessary.

The sides of a rectangle are in the ratio of 5:6. If its longer side is 7.2 in., find the shorter side, the perimeter, and the area of this rectangle. PLSSS HELP

Answers

Answer:

43.2

26.4

Step-by-step explanation:

so first if we know that the loger side's ratio is 6 we divided by 7.2

7.2 divided by 6 which is 1.2

so we mulitply the 5 by 1.2

so the shorter side is 6

6 x 7.2 = 43.2 is the area

14.4 + 12 = 26.4 is the perimeter

Answer:P2,700,000

Step-by-step explanation:

P100,000 must be added to the purchase price every year from 2009 to 2021. A formula calculating the value, V, as a function of time, t, where t is years since 2009, would be:

V(t) = P1,500,000 + (t - 2009)*(100,000)

V(2021) = P1,500,000 + (2021 - 2009)*(100,000)

V(2021) = P2,700,000
