Answer:
E; 8x9 is equal to 72 which estimated is 70
Answer:
Step-by-step explanation:
As they are similar triangles
24/AB = 24/2AD = 12/AD = (x + 2)/AD
12 = x + 2
x = 10
(y + 6) + (x - 3) / 24 = (y + 6)/(x + 2)
(y + 6) + (10 - 3) / 24 = (y + 6)/(10 + 2)
(y + 13) / 24 = (y + 6)/12
12(y + 13) = 24(y + 6)
12y + 156 = 24y + 144
12y = 12
y = 1
AC = (y + 6) + (x - 3)
AC = (1 + 6) + (10 - 3)
AC = 14
Answer:
do you have a pic
Step-by-step explanation:
Answer:
1. Incomplete
2. 8≥ 3 x + 5
⇒8-5≥3 x
⇒ 3 ≥ 3 x
Dividing both sides by 3
1≤ x or x ≥ 1 is the solution of above inequality.i.e x∈[1,0).
The solution of the above inequality is that x lies in the interval from 0 to 1 represented as 0≤x<1.
3. -2 x + 3 > 3(2 x - 1)
⇒ -2 x + 3> 3× 2 x - 3× 1 ⇒ [using distributive property which is a(b+c)=a×b + a× c]
⇒-2 x - 6 x > -3-3 →[ Bringing like terms together]
⇒ - 8 x > -6
Cancelling negative sign from both sides
if ,-a>-b, then a<b.
⇒8 x< 6
⇒x<6/8
⇒x<3/4
x∈(-∞,3/4)
The solution of the above inequality is x should be less than three by four.
Answer:
B. The solution is valid because all steps to solve the inequality for F are correct.
Step-by-step explanation:
F - 32 ≤ 0
Add 32 to both sides of the equation to have;
F -32 + 32 ≤ 0 + 32
F ≤ 0 + 32
F ≤ 32
It can be observed that to solve for F, the steps are correct. Thus the solution is valid. Therefore, the correct choice in the given question is the solution is valid because all steps to solve the inequality for F are correct.
