LenaWriter [7]3 years ago

Answer: x=1.5811389999999999 , or 1.59

Step-by-step explanation:

First, Subtract 20 from both sides.

      12x2+20−20=50−20

      12x2=30

 Then, Divide both sides by 12:

12x^2/12 = 30/12

⇒ you get : x^2 = 5/2

After, Take square root.

x= ± √ 5/2

Finally you answer is going to be =1.5811389999999999 OR, 1.59

frozen [14]

Answer:

Brad picked 130 apples. Andy picked 45 apples. Krystal picked 115 apples.

Step-by-step explanation:

B = 2Y                A = Y - 20            K = Y + 50        B + A + K + Y = 355

130 = 2(65)        45 = 65 - 20        115 = 65 + 50     130 + 45 = 115 + 65 = 355

130 = 130           45 = 45                115 = 115

Plz answer ASAP need help
Aleks04 [339]

Answer:

4 hours

Step-by-step explanation:

Let the number of hours = x.

Jay reads 55 pages per hour, so in x hours, he reads 55x pages.

After reading for x hours, he has 278 - 55x pages left to read.

Odhran reads 45 pages per hour, so in x hours, he reads 45x pages.

After reading for x hours, he has 238 - 45x pages left to read.

Since we want to know when they have the same number of pages left, we set the expressions equal and solve for x.

278 - 55x = 238 - 45x

Add 45x to both sides.

278 - 10x = 238

Subtract 278 from both sides.

-10x = -40

Divide both sides by -10.

x = 4
