n=48
Answer:
108.90
Step-by-step explanation:
You start with finding
10
%
of
90
.
$
90
⋅
.1
=
$
9
You add the money and the interest to get
$
99
for the first year. However, the next year is different. It's compound interest, so you have to multiply
10
%
by
$
99
.
$
99
⋅
.1
=
$
9.90
$
99
+
$
9.90
=
$ 108.90 The total would then be $
108.90 i think lol
Answer:
y = 3x + 12
Step-by-step explanation:
y = 3x - 5 (y = 3x +b)
Parallel lines have same slope.
m = 3; (-2 , 6)
y - y1 = m(x -x1)
y - 6 = 3(x -[-2])
y -6 = 3(x + 2)
y - 6 = 3x + 6
y = 3x + 6 + 6
y = 3x + 12
Answer:
Step-by-step explanation:
- Total number of plants = 15
- Total cost = $96
- Cost of pink flowering plant = $8
- Cost of purple flowering plant = $5
<u>Let x and y be the number of plants bought. Then we have equations:</u>
- 8x + 5y = 96
- x + y = 15 ⇒ y = 15 - x
<u>Substituting y in the first equation:</u>
- 8x + 5y = 96
- 8x + 5(15 - x) = 96
- 8x + 75 - 5x = 96
- 3x = 96 - 75
- 3x = 21
- x = 7
Correct option is the second one
Let x represent the number of spaniels
4x + x = 30
combine like terms
5x = 30
divide each side by 5
x = 6
There are 6 spaniels.
