Step-by-step explanation:

Step-by-step explanation:

240,000 = 24 x 10^4

24 followed by 4 zeros = 24 x 104

Just make the number of zeroes be the exponent for 10

24 = 24 x 10^0

240 = 24 x 10^1

2400 = 24 x 10^2

24000 = 24 x 10^3

240,000 = 24 x 10^4 miles

The two lines never intersect

Answer:

A

Step-by-step explanation:

y = 5x + 6 → (1)

y - 5x = 7 ( add 5x to both sides )

y = 5x + 7 → (2)

Substitute y = 5x + 7 into (1)

5x + 7 = 5x + 6 ( subtract 7 from both sides )

5x = 5x - 1 ( subtract 5x from both sides )

0 = - 1 ← is False

This indicates the system has no solution

(7a*2b)+3c=3c+(7a*2b) the property for the given expression is Option A) Commutative Property of Addition.

The given expression is (7a*2b) + 3c = 3c + (7a*2b). This equation demonstrates the Commutative Property of Addition.

The Commutative Property of Addition states that the order in which numbers are added does not affect the result.

In mathematical terms, it can be written as: a + b = b + a.

In your expression, you have terms involving both addition and multiplication. However, since addition is involved on both sides of the equation, we can focus on the addition aspect.

(7a*2b) + 3c = 3c + (7a*2b)

First, we can rearrange the terms on the left side:

7a*2b + 3c = 3c + 7a*2b

Now, observe that the terms on both sides of the equation are the same: 7a*2b and 3c.

They are just arranged in a different order. This aligns with the Commutative Property of Addition, which says the order of addition doesn't matter.

Therefore, the expression is an illustration of this property, and the correct answer is the Commutative Property of Addition (A).

In summary, the expression shows that changing the order of terms within an addition does not change the result, thus demonstrating the Commutative Property of Addition.

Answer:

j=10-3k

Step-by-step explanation:

here you go...i hope it's correct

If the equation is (3j+k)/2=15-4k then j=10-3k

Two or more expressions with an Equal sign is called as Equation.

The given equation is (3j+k)/2=15-4k

We need to prove j=10-3k

(3j+k)/2=15-4k

Apply cross multiplication and solve for k

3j+k=2(15-4k)

3j+k=30-8k

Subtract k from both sides

3j=30-9k

Divide both sides by 3

j=10-3k

Hence, if the equation is (3j+k)/2=15-4k then j=10-3k

Answer:

8 : 24 = 1 : 3

Step-by-step explanation:

The ratio is not in lowest terms so we found an equivalent ratio by simplifying

We can simplify the ratio 8 : 24 by dividing both terms by the greatest common factor (GCF).

The GCF of 8 and 24 is 8.

Divide both terms by 8.

8 ÷ 8 = 1

24 ÷ 8 = 3

Therefore:

8 : 24 = 1 : 3

Step-by-step explanation:

The vertex is the coordinates of the turning point of the parabola

The axis of symmetry is a vertical line passing through the vertex with equation

x = c ( where c is the x- coordinate of the vertex )

vertex = (0, 0 ) , axis of symmetry is x = 0 ( the y- axis )

(1)

vertex = (- 2, 4 ) , axis of symmetry is x = - 2

(2)

vertex = (7, 1 ) , axis of symmetry is x = 7

(4)

vertex = (- 3, - 2 ) , axis of symmetry is x = - 3

Answer:

5 , |-5|

Step-by-step explanation:

2 of the above are the absolute value of 5

The two numbers whose absolute value is 5 are 5 and -5.

Numbers whose absolute value is 5 can be both positive and negative.

The absolute value of a number is its distance from zero on the number line, so any number that is 5 units away from zero in either the positive or negative direction will have an absolute value of 5.

Here are the numbers whose absolute value is 5:

5 (positive 5, because it's 5 units to the right of zero)

-5 (negative 5, because it's 5 units to the left of zero)

Hence, 5 and -5  are the two numbers whose absolute value is 5.

Answer:

207 cm

Step-by-step explanation:

Because ΔPQR ≅ΔSTU and the longest side in the ΔPQR is RP then the longest side in ΔSTU must be SU = 92 cm

Perimeter of triangle PQR is

P(ΔPQR) = 36+48+24 = 108 cm

Because the triangles are are similar their sides are in proportion.

But how much bigger did the second triangle get?...is (92/48) times bigger

P(ΔSTU) = 180*(92/48) = 207 cm

...you can also use proportions to find each side and then find the perimeter

TU = 24*92 /48 = 46

TS = 36*92/48 = 69

SU = 92

P(ΔSTU) = 92+69+46 =207 cm

The answer is n=16

Step-by-step explanation:

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

−29=−13−n

Step 1: Simplify both sides of the equation.

−29=−13−n

−29=−13+−n

−29=−n−13

Step 2: Flip the equation.

−n−13=−29

Step 3: Add 13 to both sides.

−n−13+13=−29+13

−n=−16

Step 4: Divide both sides by -1.

−n/−1 =−16/−1
