Solve for x. ←2x+6 X+9 x = [?]

Mathematics
1 answer:
Scorpion4ik [409]1 year ago
4 0

Answer:

3

Step-by-step explanation:

A simple way to solve this is by substituting, we start with trying 1 for x, 2+6=8, and 1+9=10. Because the two values are different, that means 1 is the incorrect value. We can try 2, 4+6=10, and 2+9=11, once again inequivalent. We finally try 3, and 6+6=12 and 3+9=12 meaning x must be 3

We can multiply the number of parts Marsha has finished by the miles of each part:

5 × 1/10

= 5/10

=1/2

Therefore, she raced 1/2 miles.

Hope it helps!

Suppose a population of 140 crickets doubles in size every month. The function f(x) = 140∗2x gives the population after x months
Tema [17]
The equation would then be f(x) = 140 x 2(24)

There will be 6,720 crickets in 2 years

A grid shows the positions of a subway stop and your house. The subway stop is located at (7, -6) and your house is located at (
Yuri [45]

So the distance between subway stop and house is 19 units

Step-by-step explanation:

The distance formula will be used to calculate the distance between home and subway.

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Here (x1,y1) are the coordinates of first point

and

(x2,y2) are the coordinates of second point

Given

(x1,y1) = (7, -6)

(x2,y2) = (-9,5)

Putting the values in the formula

d=\sqrt{(-9-7)^2+(5-(-6))^2} \\=\sqrt{(-16)^2+(5+6)^2} \\=\sqrt{256+(11)^2}\\=\sqrt{256+121}\\=\sqrt{377}\\=19.41\ units

Rounding off to nearest unit gives us 19.

So the distance between subway stop and house is 19 units
