Answer:
Jerry has a number of 39, and Mary has a number of 50.
Step-by-step explanation:
Let's say mary's number is x, and jerry's is y.
x-y=11 and y+x=89. This means if we subtract 11 from 89 we get jerry's number times 2, which is 78. 78 divided by 2 is 39.
Jerry has a number of 39
and Mary has a number of 50.
Answer:
yes
Step-by-step explanation:
y = - 5x + 4
x = - 2
y = -5(-2) + 4 Two minuses make a plus
y = 10 + 4 Add
y = 14
((r²+7r+10)/3) × (3r-30)/(r²-5r=50)
= Factoring the expression (r²+7r+10) we get (r+2)(r+5)
Then multiply it with the other numerator, we get
= (r+2)(r+5)(3(r-10)
Then we factorise
= (r²-5r-50) = (r+5)(r-10)
Multiplying it with the other denominator, we have;
= 3(r+5)(r-10)
Therefore dividing
(r+2)(r+5)(3(r-10)/(3(r+5)(r-10) we get;
= r+2
Therefore, the correct answer is r+2
Answer:
Step-by-step explanation:
AD = DC and BE=EC ⇒
DE = 1/2AB
- 4x + 1 = 1/2(11x - 25)
- 2(4x + 1) = 11x - 25
- 8x + 2 = 11x - 25
- 11x - 8x = 2 + 25
- 3x = 27
- x = 27/3
- x = 9
DE = 4*9 + 1 = 36 + 1 = 37
