Area,for rectangles is length x width so 2 1/4 inches x 3 1/2 inches is 7 7/8
Answer: the 4th one I think
Step-by-step explanation:
<span>1/5(2x-15) + (3/5)x = 4 1/4
</span><span>x*2/5 - 15/5 + x*3/5 = 4 1/4
</span><span>x*2/5 - 3 + x*3/5 = 4 1/4
</span><span>x*(2/5+3/5) - 3 = 4 1/4
</span><span>x*(5/5) - 3 = 4 1/4
</span>1*x - 3 = 4 1/4
<span>x= 4 1/4 + 3
</span><span>x= 7 1/4 </span>
Let the number of dimes = xLet the number of quarters = y You know that each dime is worth $0.10You know that each quarter is worth $0.25 Using the variables above, we can write two equations that represents the total number of coins and total amount. x + y = 47 eq10.10x + 0.25y = 8 eq2 You can use the substitution/elimination method to solve for x and y.<span>3/6/2017 </span>| Michael J.<span>
