Answer:

9

Step-by-step explanation:

You know that the the center line is equal to half the sum of the legs, because it is the midline. You add the legs together (7x+13) and (5x+7), and you get 12x+20. Divide that by 2 and you get 6x + 10. The midline is 8x-8, so you set up an equation, and get 6x+10 = 8x-8. That simplifies to 18=2x. Divide both sides by 2 and you get x = 9

Answer:

7

Step-by-step explanation:

Move the -8 to the other side and use the rule change side change sign:

2x=6+8

2x=14

Move the 2 and convert the multiplication(as its 2×x ) into division:

x= 14÷2

The ratio between two no is 2:3 . if the consequent is 24 the antecendent is

Irina18 [472]

antecedent : 16

ratio: 2 : 3

=========

antecedent : 2

consequent : 3

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

$\rightarrow \sf \dfrac{2}{3}=\dfrac{x}{24}$ [ x is antecedent ]

$\rightarrow \sf 2(24)=3(x)$

$\rightarrow \sf 48=3(x)$

$\rightarrow \sf x= 16$

Additional information:

In the ratio, a : b Here the "antecedent is a" and "consequent is b"

A rectangular box is 10 in. wide, 10 in. tall, and 8 in. long. What is the diameter of the smallest circular opening through w

lutik1710 [3]

Answer:

Diameter of smallest circular opening = 12.81 in

Step-by-step explanation:

Given:-

Width of rectangular box(W)=10 in.

Length of rectangular box(L)=8 in.

Height of rectangular box(H)=10 in.

For box to fit in the smallest circular opening we need to find the diagonal of the rectangular box, therefore

diagonal of rectangular box=diameter of smallest circular opening

So,

$Diagonal\ (d)=\sqrt{width^{2}+length^{2} }$

$d=\sqrt{W^{2} +L^{2} }$

$d=\sqrt{10^{2}+8^{2}}$

$d=\sqrt{100+64}$

$d=\sqrt{164}$

$d=12.81\ in.$

$\therefore\ diagonal\ (d)=12.81\ in$

Therefore diameter of smallest circular opening = 12.81 in.

You can put a fraction in an exponent. x2/3 should be typed like x^(2/3). ... might think this means "the quantity 'x-squared plus 1' over the quantity 'x minus 5'.Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x ...3 over x minus 5 over x plus 2 (232693) | Wyzant Resourceshttps://www.wyzant.com › Resources › AnswersAug 1, 2013 - Anton, for this kind of problem you have to use parentheses, to avoid double reading!!
