Hi There!
-----------------------------------------------------------
Solution:
a = anna
d = dasha
a + 39 = d * 4
We can say that:
a = 1
d = 10
1 + 39 = 10 * 4
40 = 40
Answer:
Dasha had 10 rose bushes originally.
I hope this helps :)
104
Step-by-step explanation:
Hello! :)
-----------------------------------------------------------------------------------------------------------------
Dasha=d, Anna=a
d=4a
d-39=a+39
d=a+78
Plug in d as 4a:
4a=a+78
Solve for a:
3a=78
a=26
Because d=4a, plug in a:
d=4*26
d=104
Dasha originally have 104 rose bushes
x < 6
1. 3x+2x = 5x
2. 5x - 8 < 22
3. 22+ 8 =30
4. 5x < 30
5. 30/5 = 6
6. x < 6
170.72
to find the mean, we must add al the numbers and divide it by n
that is,
164,175,178,166,167,145,176,150,174,162,180,156,173,158,182,184,160,172,186,168,195,169,171,187,170 we have to add al these numbers and divide it by 25
sum- 4628 divided by 25
=170.72
P(X<1) = .216 P(X</=1) = .648
its right
(- 2, 3 )
Given the 2 equations
x + y = 1 → (1)
2y - x = 8 → (2)
Adding the 2 equations term by term will eliminate the x- term
(x - x) + (y + 2y) = (1 + 8), that is
3y = 9 ( divide both sides by 3 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for y
Substituting y = 3 in (1)
x + 3 = 1 ( subtract 3 from both sides )
x = - 2
Solution is (- 2, 3 )
