3x+15−7x=−7
Simplify:
3x+15−7x=−7
3x+15+−7x=−7
(3x+−7x)+(15)=−7(Combine Like Terms)
−4x+15=−7
Subtract 15 from both sides.
−4x+15−15=−7−15
−4x=−22
Divide both sides by -4.
−4x/−4=−22/−4
x=11/2
Answer:
m= 2/17
Step-by-step explanation:
do the formula x1 and y1 and x2 and y2
x1, y1 x2, y2
(-11,15) (23,19)
when subtracting you ALWAYS START WITH YOUR Ys
19-15= 4
now subtract your Xs
23- (-11)= 34
now your answer is 4/34
but that's not the last step you can simplify it and make it smaller,
they both go into 2 so know divide both of then numbers by 2
and you should get 2/17
your final answer should be 2/17

Answer:
CD = 14 cm; DE = 21 cm
Step-by-step explanation:
The perimeter is the sum of side lengths (in centimeters), so ...
CD + DE + CF + EF = 55
CD + DE + 8 + 12 = 55 . . . . . . . substittute for CF and EF
CD + DE = 35 . . . . . . . . . . . . . . subtract 20
___
The segment DF is a diagonal of the rhombus, so bisects angle D. That angle bisector divides ΔCDE into segments that are proportional. That is, ...
CD/DE = CF/EF = 8/12 = 2/3
___
So, we have two segments whose sum is 35 (cm) and whose ratio is 2 : 3. The total of "ratio units is 2+3=5, so each must stand for a length unit of 35/5 = 7 (cm). The sides are ...
CD = 2·7 cm = 14 cm
DE = 3·7 cm = 21 cm
<em>Check</em>
CD + DE = (14 +21) cm = 35 cm . . . . . matches requirements
Answer:
- <u><em>31 animals</em></u>
Explanation:
The question is in French language. The translation to English is:
<em>1 rabbit saw 6 elephants while going to the river. Each elephant saw 2 monkeys go towards the river. Each monkey holds 1 parrot in its hands.</em>
<em>How many animals are going to the river?</em>
<em />
<h2>Solution</h2>
<em />
Animal amount
Rabbit 1
Elephants 6 (the rabbit saw 6 elephants)
Monkeys: 6 × 2 = 12 (2 monkeys per elephant)
Parrots: 12 × 1 = 12 (1 parrot per monkey)
=============================
Total: 1 + 6 + 12 + 12 = 31 animals ← answer
