8o+12y=362
12o+8y=388
Im choosing “o” for orchid and “y” for lily
20o+20y=750
20o=750–20y
o=37.5–y
(37.5–y)+20y=750
-y+20y=712.5
19y=712.5
y=37.5
So, lilies sell for $37.50
Answer:
-22/7
Step-by-step explanation:
To divide fractions, we multiply by the reciprocal:
(6/-7)/(3/11)
(6/-7)(11/3)
66/-21
22/-7
-22/7
Therefore, your simplifed answer is -22/7
<u>Given:</u>
A triangle ABC where AD = 12 units, AB = 15 units, and AC = 13 units.
<u>To find:</u>
The length of BC.
<u>Solution:</u>
According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.
There are 2 triangles, ACD and ABD in triangle ABC.
In triangle ACD, AC is the hypotenuse.
In triangle ABD, AB is the hypotenuse.
Assume the length of CD is x and the length of DB is y.
For triangle ACD,
For triangle ABD,
units.
So BC is option C. 14 units long.
Answer:
= -48
Step-by-step explanation:
3x^3 - 8y^2
3 ( 2 )^3 - 8 ( -3 )^2
first you solve the exponents
3 ( 8 ) - 8 ( 9 )
multiply
24 - 72
subtract
= - 48
hope this helps
