Hi there!!
First, Let plain shirts be x
Let fancy shirts be y
x + y = 7
15x + 28y = 131
Multiply first equation by 28 to eliminate y:
28x + 28y = 196
<span>15x + 28y = 131
</span>Subtracting the two equations:
13x = 65
<span>x = 5 </span>
Substituting x to get y:
x + y = 7
5 + y = 7
<span>y = 2 </span>
<span>Answer: 5 plain shirts and 2 fancy shirts
</span>
Hope this helps u!!
Have an amazing rest of ur day:)))
Answer:
I think its A
Step-by-step explanation:
I factored the polynomial and its factors turned out to be (x-1)(x^2-2x-4), which eliminated the possibilities of 2 and 3. Then i replaced the (-1) in the place of the x and it turned out to be equal to 2, making the first statement true.
Answer:
x=b^2+d^2/a-c
Step-by-step explanation:
Step-by-step explanation:
solve it through simultaneous equations
for fun guys : 10+6.5x=y
for game bank : 22+3.5x=y
10+6.5x=22+3.5x
3x=12
x=4

that cost= $36
Answer:
John's and Amber's wages are proportional to time. John's unit rate it $9 per hour. Amber's unit rate is $8 per hour
Step-by-step explanation:
The table(johns) shows this because he earns $9 more for every extra hour he works. this makes the unit rate $9 an hour.
The graph(ambers) shows that her pay increases at a steady rate, hitting a multiple of 8 every hour. This makes the unit rate $8 an hour.
