Answer: 14 dimes and 8 quarters
<u>Step-by-step explanation:</u>
dimes ($0.10): x + 6
quarters ($0.25): x
Cost*quantity of dimes + Cost*quantity of quarters = Total value
0.10(x + 6) + x(0.25) = 3.40
0.10x + 0.60 + 0.25x = 3.40
0.35x + 0.60 = 3.40
<u> -0.60 </u> <u>-0.60 </u>
0.35x = 2.80
<u>÷0.35 </u> <u>÷0.35 </u>
x = 8
dimes: x + 6 = 8 + 6 = 14
I think its 0.6 because 2-5=3 and 2-(-3)=5 and 3÷5=0.6
Answer: 2.25
Explanation:
Let the width be x
Length = 3x
Perimeter of frame = 18
2(l + w) = 18
2(3x + x) = 18
2(4x) = 18
8x = 18
x = 18/8
x = 2.25 feet
B) {−5, −4, 2}
