Answer:
41,42,43
Step-by-step explanation:
3x+9=36
with 2 times 9kg and 18kg is the solution:
I:2x+y=36
II:y=x+9
if you substitute y of II into I:
3x+9=36
3x=27
x=9
-> 2 boxes with 9kg and 1 with 9+9=18 kg
2*9+18=36kg in total
so the third option/Rashid is the solution
Answer:
√13 + 3 = x
-√13 + 3 = x
Step-by-step explanation:
y = x² - 6x - 4
0 = x² - 6x - 4
0 + 13 = x² - 6x - 4 + 13
13 = x² - 6x + 9
13 = (x-3)²
±√13 = x-3
±√13 + 3 = x
√13 + 3 = x
-√13 + 3 = x
Answer: m24+70
Step-by-step explanation: A. Triangle C'D'E' is a translation of triangle ... C. Sides DE and D'E' have the same length. D. Each vertex is translated 4 units to ... C. ZB and B' are congruent angles. ... She will rotate the figure 90° clockwise, 180°, and then 90° counterclockwise. ... Which angles have the same measure ... The m24 = 70° What is the m27?
Answer:
Step-by-step explanation:
From the figure,
<h3>∠1 = ∠2 </h3>
- (Alternate angles are equal)
<u>We know that:</u>
- ∠1 = 10x + 2
- ∠2 = 12x - 22
So,
<h3>10x + 2 = 12x - 22</h3>
Add 22 to both sides
10x + 2 + 22 = 12x
10x + 24 = 12x
Subtract 10x to both sides
24 = 12x - 10x
24 = 2x
Divide 2 to both sides
12 = x
OR
<h3>x = 12</h3>
Given that,
∠2 = 12x - 22
Put x = 12
∠2 = 12(12) - 22
∠2 = 144 - 22
<h3>∠2 = 122°</h3>
