11) Write and solve a system of equations for this situation. Solve for each variable.
As treasurer of her school's 4H club, Carol wants to buy gifts for all 18 members. She
can buy t-shirts for $9 and sweatshirts for $15. The club has $180 to spend and Carol
wants to spend all of the money. How many of each type of gift should she buy?
Equation for members:
Let x =
Equation for money:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: 323 is how many she has ☃☃⛄❄

step-by-step explanation:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
