Answer:
d=104
Dasha's garden had 104 originally
Step-by-step explanation:
let d for dasha and a for Anna
d=4a
a=d/4
d-39=a+39
d-39=d/4 +39
d-d/4=39+39
3/4 d =78
3d=4*78
d=(4*78)/3
d=312/3
d=104
Dasha's garden had 104 originally
cones
cylinders
spheres

Answer:
Step-by-step explanation:
This is an inequality, not an equation. There will be a set of x-values for which the inequality will be true.
First eliminate the fractional coefficient 2/5 by multiplying all terms by 5:
25 < 2x + 15 ≤ 75
Subtracting 15 from each 5, (2/5)x, 3 and 15 yields:
22 < 2x ≤ 60
Dividing all three terms by 2, we get:
11 < x ≤ 30
Thus, any number greater than 11 but equal to or less than 30 is a solution.
