Answer: 12.5%
Step-by-step explanation:
80x 12.5%=10
80+10=90
X=skirt
y=sweater
z=shoes
x+y+z=165
y=8/7x
z=x+11
plug it in
x+(8/7x)+(x+11)=165
2x+8/7x=154
22/7x=154
x=49
y=56
z=60
a skirt cost $49, a sweater cost $56, and a pair of shoes cost $60
Answer:
18/10
Step-by-step explanation:
Answer:
Step-by-step explanation:
The point slope form of a straight line is expressed as
y - y1 = m(x - x1)
Where
m represents slope of the line
y1 represents the initial value of y
x1 represents the initial value of x
If two lines are parallel, it means that they have the same slope. From the equation of the given line, slope = 1/2
Therefore,
m = 1/2
x1 = - 3
y1 = - 2
Substituting into the point slope equation, it becomes
y - - 2 = 1/2(x - - 3)
y + 2 = 1/2(x + 3)
The equation is
y + 2 = 1/2(x + 3)
Answer:
21
Step-by-step explanation:
<em>Step 1: add 2 to 5</em>
=> 2 + 5
=> 7
<em>Step 2: Multiply the result by 3:</em>
=> 7 * 3
=> 21
Therefore the <u>final answer = 21</u>
Hope this helps!
