pennies=8 % of 50=8/100×50=4

dimes=40 % of 50=40/100×50=20

nickels=4+3=7

quarters=50-(4+20+7)=50-31=19

total money=4+20×10+7×5+19×25

Answers

Essentially just turn the big number into an exponent so u can cancel out and be left with just the x for example 128 is the same as 2^7 and when you have it like that you simply cancel the 2 and are left with x=7

A) x=7
B) x=6
C) x=4
D) x=8
E) got cut off theres no value
F) x=2
G) x=3

Solve the equation.
1/10 (x + 34) = −2(4 − x)
x = _____

HELPPP PLZZ DUEE TODAYY

Answers

Answer:

−0.383

Step-by-step explanation:

Let's solve your equation step-by-step.

1/10 (x+34)=(−2(4−x))(x)

Step 1: Simplify both sides of the equation.

1/10 x+ 17/5 =2x2−8x

Step 2: Subtract 2x^2-8x from both sides.

1/10 x+ 17/5 −(2x2−8x)=2x2−8x−(2x2−8x)

−2x2+ 81/10 x+17/5 =0

For this equation: a=-2, b=8.1, c=3.4

−2x2+8.1x+3.4=0

Step 3: Use quadratic formula with a=-2, b=8.1, c=3.4.

x=

−b±√b2−4ac

2a

x=

−(8.1)±√(8.1)2−4(−2)(3.4)

2(−2)

x=

−8.1±√92.81

−4

x=−0.38344867082526823,4.433448670825268

Step 4: round to the nearest hundred

X= -0.383

Trapezoid ABFE is similar to trapezoid EFCD. What is the length of DC?

Answers

Answer:

6.75

Step-by-step explanation:

Find the relationship between the trapezoids. You can see that the top of trapezoid ABFE is 3 units and the top of EFCD is 4.5 units. 3 * 1.5 = 4.5, so t the sides of trapezoid EFCD are 1.5 times more than the sides of ABFE.

Now, you know the bottom of ABFE is 4.5, so the bottom of EFCD is 1.5 times longer because they are proportional, so you can do 4.5 * 1.5 = 6.75 units.
