Answer:
2000 = 24x + 20y (x represents hours and y represents money per sale)
she must make 88 sales
Step-by-step explanation:
2000 = 24(10) + 20y
2000 = 240 + 20y
-240 = -240
1760 = 20y
/20 = /20
88 = y
Answer: True
Explanation: Using a^2 + b^2 = c^2 method.
5^2 + 12^2 = 169.
13^2 = 169.
169 = 169.
Hope this helps.
Answer:
The cost of a pair of trousers and a shirt is $46 and $3 respectively.
Step-by-step explanation:
Let us assume the pairs of trousers be X
And, the pairs of trousers be Y
So, the first equation is
2X + 3Y = $101
And, the second equation is
7X + 3Y = $331
Now substituting this two equations
2X + 3Y = $101
7X + 3Y = $331
-5X = -$230
X = $46
Now put the X values in one of the equation to find out the Y value
So,
2 × $46 + 3Y = $101
$92 + 3Y = $101
Y = $3
Answer:
$13.10 represents the rate of change
Step-by-step explanation:
13.1 is the only value in the equation with a variable (g). There is an additional $13.10 charge for every gigabyte used over the limit, and this is the rate of change.
For example, if 5 gigabytes were used over the limit, the charge would be 13.1(5) or $65.50
Answer:
x=0
y=6
Step-by-step explanation:
3y- 12x = 18
2y-8x= 12
rearrange the equation
2y-8x=12
add 8x to both sides
2y=8x+12
divide both sides by 2
y=4x+6
now substitute it into 3y-12x=18
3(4x+6)-12x=18
simplify
12x+18-12x=18
simplify
18=18
x=0
substitute to find y
2y-8(0)=12
2y=12
y=6
Recheck:
3(6)-12(0)=18
18=18
2(6)-8(0)=12
12=12
