What is the value of x?

Mathematics

bazaltina [42]3 years ago

Answer: 15
Explanation:
Let’s assume A = 5x -24 and B = 8x+9. Also, let’s assume the angle right beside B = C just so it doesn’t get confusing.
The two triangles are congruent so all the angle of the vertices for the smaller triangle align with the angle of the vertices for the bigger triangle. Since the triangles are the congruent, we can assume that Angle A also applies to angle C. So far, C = 5x -24. If you look carefully, C and B form a straight line (180 degrees).
180 = C + B
180 = (8x+9) + (5x-24)
180 = 13x- 15
13x = 195
x = 15

Sergeu [11.5K]

Answer:

Perimeter of square Q is 49 inches.

Step-by-step explanation:

Let x be the length of side of square P and y be that of square Q.

It is given in the question that :

\frac{x}{y}=\frac{2}{7}

Also it is given that x=3.5 inches.Hence

\frac{3.5}{y}=\frac{2}{7}

∴ y=12.25 inches.

Perimeter of square Q is 4y = 4\times12.25=49 inches.

Which integer is closest to 0 on the number line?
Elenna [48]
The answer is C, 1.
In a number line, the larger number it gets, the more of the right side they're. The smaller the number, the more left side they get.
So, on a number line, 1 is just at the right side of 0, all the other options are at least one more place away from 0.

<h3>Answer:  2</h3>

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

Explanation:

x = number of years

y = height in feet

The equation for the first tree is

y = x+3

The slope is 1 to represent a rate of 1 ft per year of growth. The y intercept of 3 is the starting height. Refer to y = mx+b form.

For the second tree, the equation is:

y = 0.5x+4

This time we have a slope of 0.5 and a y intercept of 4.

Apply substitution to solve for x

y = x+3

0.5x+4 = x+3

0.5x-x = 3-4

-0.5x = -1

x = -1/(-0.5)

x = 2

The trees will be the same height in <u>  2  </u> years.

What will that height be? Plug x = 2 into either equation to find y. We should get the same y value.

y = x+3

y = 2+3

y = 5

Or we could say

y = 0.5x+4

y = 0.5*2+4

y = 1+4

y = 5

We've shown that both equations lead to y = 5 when x = 2. This means that at the 2 year mark, both trees are 5 feet tall. This helps confirm we have the correct x value.
