Y=1/2x+3<br> -x+27=-6 <br><br> solve using substitution

Nat2105 [25]

Answer:

y= 19.5 x=33

Step-by-step explanation:

-x + 27= -6

(subtract 27 on both sides)

-x= -33

(divide by negative 1 on both sides)

x= 33

(substitute x into the first equation)

y= 1/2x + 3

y= 1/2(33) +3

y= 16.5 +3

y= 19.5

hope this helps :))

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)

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.25 before the discount, and

soldi70 [24.7K]

Answer:

$82.16

Step-by-step explanation:

78.25 * .20 = 15.65 as a tip,

78.25 *.15 = 11.74 as the discount, subtract from initial value:

78.25 - 11.74 = 66.51

then add the tip: 15.65 + 66.51 = $82.16
