X is t shirt is $8
Y is sweatshirt $11
2x+2y=38
3x+1y=35
We will be using the elimination process so you want even them out same value
2x+2y=38
-6x-2y=-70 ( want get rid of the y-value by increasing to other by when both add or subtract it will equal 0)
-4x=-32
Divide both -4
X=8 So 8 dollars a t-shirt so now will fill x with 8
2(8)+2y=38
16+2y=38
-16
2y=22
Divid by 2
Y = 11 so a sweatshirt is 11 dollars
You can check by fill each by the variable
Answer:
second option
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 
and (a, b) = (4, 
) , thus
y - = (x - 4)
The pertinent formula is i = p*r*t. Here, i = $6,300, r = 0.07 and t = 5 yrs.
We want to solve this for the principal, p. Since i = p*r*t, p = i / (rt). In this case, the principal was:
p = $6,300 / [0.07*5] = $6,300 / 0.35 = $18,000
Hey! The drink was $1.15 because $10 minus the cost of the lunch ($7.75), tax (0.47), and what was given back in change (0.63) leaves you with $1.15
I'm pretty sure it's D because you're subtracting 30 without changing it.
