(t+9)20=140 what is t
GarryVolchara [31]

Answer:

t=-2

Step-by-step explanation:

(t+9)20=140

20t +180 = 140

Subtract 180 from each side

20t +180-180 = 140-180

20t = -40

Divide by 20

20t/20 = -40/20

t=-2

How many real number solutions does the equation have 0=5x^2+2x-12
Harman [31]
 Rearrange the equation to standard form of a quadratic equation (ax^2+bx+c=0) by switching sides: 5x^2+2x-12=0. Now, use the quadratic equation formula to solve. You should come out with x_1=sqrt61-1/5 and x_2=-1+sqrt61/5. Thus, your answer is B, or two solutions.

****BRAINLIEST GOES TO THE FIRST CORRECT ANSWER****
monitta

2x =50 since it is an isosceles triangle

x =25


the sum of all angles in a triangle is 180

5y + 10 + 50 + 2x=180

5y + 10 + 50 +50 =180  because  2x = 50

combine like terms

5y +110 = 180

subtract 110 from each side

5y = 70

y = 14
