Hi there, 3+-10=-7 so, -7+5x=13. First, we add -7 to both sides, which gives us 5x=13+7, 13+7=20, so 5x=20. Now, we divide both sides by 5, Therefore, x=4

3+5x-10=13
Put all like terms together.
5x+3-10=13
5x-7=13
Subtract.
5x=20
Divide.
x=4

Hope this helps :)

Please help <br> The diagram shows a 5ft student standing near a tree
Novosadov [1.4K]

Answer:

25 ft

Step-by-step explanation:

The diagram shows two triangles that are similar.  Similar triangles have equal angles and sides that are proportional to each other.  Since the base of each triangle is given, we can find the proportion of the sides:

\frac{smaller}{larger}=\frac{8}{40}=\frac{1}{5}

Given the ratio of the smaller to larger triangle, we can set up a proportion to find the missing height of the larger triangle:

\frac{1}{5}=\frac{5}{x}, where 'x' represent the height of the tree

cross-multiply:  x = (5)(5) or 25 ft

The length of a rectangle is 2 feet more than 5 its width. The perimeter is 52 feet. Find the dimension of the rectangle
Ber [7]

Answer: The length is 22 feet. The width is 4 feet.

Step-by-step explanation: Create an equation for the length: 2+5w=52.

Now combine the two sides to get 4+10w=52. Plug in some numbers that seem reasonable. I started with 4, checked my work and found that it was right. This problem is all about trial and error.

So, 4+10(4)= 44. Make sure to remember the width, so add 4 for each side: 44+8. 44+8=52. Hope this helps :)
