Answer:
x...third number
4x...second number
x-9...first number
(x)+(4x)+(x-9)=141
x+4x+x-9=141
6x-9=141
Let's add 9 to both sides...
9+6x-9=141+9
6x=150
Let's divide both sides by 6...
(6x)/6=150/6
x=25
third number...25
second number...(4)(25)=100
first number...(25-9)=16
Let's check our work...
25+100+16=141
141=141
Answer:
C
Step-by-step explanation:
Given
24x² - 22x + 5
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 24 × 5 = 120 and sum = - 22
The factors are - 12 and - 10
Use these factors to split the x- term
24x² - 12x - 10x + 5 ( factor the first/second and third/fourth terms )
= 12x(2x - 1) + 5(2x - 1) ← factor out (2x - 1) from each term
= (12x - 5)(2x - 1) ← in factored form → C

Step-by-step explanation:
(8/27)power5 = 5.57533755
(2/3)power7= 9.14494717
then, u just devide... from what i know
For a trapezoid, the area is:
S=(b+B)h/2, where b and B are the bases, and h is the height.
b=2
B=2+2+2=6
h=2.
S=(2+6)×2/2=8
Answer:
2
Step-by-step explanation:
<u>Given AP where:</u>
<u>To find</u>
<u>Since</u>
- a₄ = a₁ + 3d
- a₂ = a₁ + d
- a₆ = a₁ + 5d
<u>Initial equations will change as:</u>
- a₁ + 3d = 2(a₁ + d) - 1 ⇒ a₁ + 3d = 2a₁ + 2d - 1 ⇒ a₁ = d + 1
- a₁ + 5d = 7 ⇒ a₁ = 7 - 5d
<u>Comparing the above:</u>
- d + 1 = 7 - 5d
- 6d = 6
- d = 1
<u>Then:</u>
- a₁ = d + 1 = 1 + 1 = 2
- a₁ = 2
The first term is 2
