we have
x ----> number of hats the sold
y ----> number of scarves they sold
so
12x+15y=690 ------> equation A
y=x+10 -----> equation B
Solve the system of equations
Using substitution Method
substitute equation B in equation A
12x+15(x+10)=690
solve for x
12x+15x+150=690
27x=690-150
27x=540
x=20
Find out the value of y
y=x+10
y=20+10
y=30
therefore
The answer is
<h2>20 hats and 30 scarves</h2>
Answer:
110 1/4
Step-by-step explanation:
5 1/4=21/4
21/4x21/4= 441/4= 110 1/4
im pretty sure thats correct
if not
im so sorry
Answer:
y = (7/8)x + 7
Step-by-step explanation:
"7 over 8 x" is incorrect; you meant "(7/8)x" (which is not the same as "7 over 8 x." Thus, your line is y = (7/8)x - 7. The slope of a parallel line is the same, or (7/8). Given that the line passes thru (8,0), we have enuf info with which to calculate the y-intercept. Write out: y = mx + b. Immediately replace m with (7/8), y with 0 and x with 8, obtaining: 0 = (7/8)(8) + b. Then b = 7, and the equation of this new, parallel, line is y = (7/8)x + 7.

x+x+55+x+38=180
3x+93=180
3x=87
x=29°
