The ratio of the side lengths of a quadrilateral is 3:3:5:8, and the perimeter is 380cm. What is the measure of the longest side
MariettaO [177]

Answer: The second option (160 cm)

Step-by-step explanation:

1. You can obtain the perimeter of a quadrilateral by adding the lenghts of the sides.

2. You know that the ratio of the side lengths is 3:3:5:8 and the perimeter is 380 centimeters.

3. Therefore, you can write the following expression, where x is an integer:

3x+3x+5x+8x=380

4. Solve for x:

3x+3x+5x+8x=380\\19x=380\\x=\frac{380}{19}\\x=20

5. Therefore, the longest side is:

8x=8*20=160 (160 cm)

Find the value of the variable and GH if H is between G and I. GI = 5b + 2, HI = 4b – 5, HI = 3
LenKa [72]

Answer:

b = 2, GH = 9

Step-by-step explanation:

In this problem we have that

GI=GH+HI

Solve for GH

GH=GI-HI -----> equation A

we have

GI=5b+2 -----> equation B

HI=4b-5 ------> equation C

HI=3 -----> equation D

step 1

Substitute equation D in equation C and solve for b

3=4b-5

4b=3+5

4b=8

b=2

step 2

Find the value of GH

substitute equation B and equation D in equation A

GH=(5b+2)-3

GH=5b-1

substitute the value of b

GH=5(2)-1=9

What is the value of x in the equation 4 . 10 X+52 3 +35x+1 5 ?<br><br>:)​
pashok25 [27]

Answer:

x=-3

Step-by-step explanation:

Given:

4\frac{3}{10}-(2\frac{2}{5}x+5\frac{1}{2})=\frac{1}{2}(-3\frac{3}{5}x+1\frac{1}{5})

Distribute to remove parentheses:

4\frac{3}{10}-2\frac{2}{5}x-5\frac{1}{2}=-\frac{18}{10}x+\frac{6}{10}

For simplification and clarity, reduce all mixed numbers to simplified common fractions:

\frac{43}{10}-\frac{12}{5}x-\frac{11}{2}=-\frac{9}{5}x+\frac{3}{5}

Combine like terms:

-\frac{12}{5}x-\frac{6}{5}=-\frac{9}{5}x+\frac{3}{5}

Add 6/5 to both sides, then add 9/5x to both sides:

-\frac{3}{5}x=\frac{9}{5}

Divide both sides by -3/5 to isolate x (recall dividing by a number is equal to multiplying by its reciprocal):

x=\frac{9}{5}\cdot -\frac{5}{3}, \\x=\frac{-9}{3},\\x=\boxed{-3}
