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

Answer:
JL = 9√13
Step-by-step explanation:
All of the triangles in this geometry are similar:
∆MKL ~ ∆MLJ ~ ∆LKJ
Corresponding sides of similar triangles are proportional, so you can write the relations ...
JL/JM = JK/JL ⇒ JL² = JM·JK
LM/JM = KM/LM ⇒ LM² = JM·KM
Using the second expression to find JM, we have ...
JM = LM²/KM = 18²/12 = 27
We know that JK = JM +KM. Then the first expression can be ...
JL² = 27·(27 +12) = 9²·13
JL = 9√13
If two unrelated triangles, then C mainly because you're not given any information on DEF.
If ABC=DEF, then the answer would be A.
Gradient of line= (y2-y1)/(x2-x1)
Gradient of line= (10-(-6))/(8-4)
Gradient of line= 16/4
Gradient of line= 4
Y-intercept
Y=4x+c
When x=8, y=10
10=32+c
c= -22
Equation of line
Y=4x-22
When x=b, y=2b
Y=4x-22
2b=4b-22
22=2b
b=11
if we take 6 to be the 100%, what is 8 off of it in percentage?
