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

A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 8% are pennies and 40% are dimes. There are 3 more nickels than pennies. How much money does the bag contain?
Answer:
Step-by-step explanation:
number of
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
=4+200+35+475
=714 pennies
=7.14 $

Solve x-10 > -2, and then graph the solutions. Use pencil and paper. Explain how you can use mental math to solve the inequality.
Find the area of the region bounded by the y-axis, x-axis and the line y=-2x+4.
Answer:2
Step-by-step explanation:y = 0 : 0 = -2x + 4 → x = -2 is the x-intercept. Similarly, when the line crosses the y-axis, the x-coordinate at this point will be zero and substituting x = 0 into the equation will give us the y-intercept. x = 0 : y = 0 + 4 → y = 4 is the y-intercept.
Answer:
The correct answer is 4

Trapezoid ABFE is similar to trapezoid EFCD. What is the length of DC?
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.
now find the difference whats 3 2/3- 1 4/5 (may mark as brainliest)

Need help with a math problem
Answer:
No
Step-by-step explanation:
Here's what's going on: some person buying their furniture sees this sofa and it's $1200. That person sees theres a 1/3 off sale! They're happy and buy their sofa with a 20% off discount they got.
Now we have to find out if they should use the 20% off discount before or after adding the 1/3 off sale.
The answer is, they're both the same.
Say they add the 1/3 off sale discount and then use their 20% off discount. Find the 1/3 off sale: 1200 divided by 3 (because fractions are division problems) = 400. 20% of 400: 400 x 0.2 = 80. It's not just 80, because it's not an "only pay 20%" discount. 400 - 80 = 320. They'd pay $320 with this method.
This shows that using the 20% discount after the 1/3 off sale the customer spends $320.
Now let's calculate what happens if they use the discount after the 1/3 off sale. 20% of 1200: 1200 x 0.2 = 240. 1200 - 240 = 960. Now adding the 1/3 off sale: 960 divided by 3 = 320. They'd also pay $320 with this method.
If it's a short answer, you could just write something like, "No, both methods end up with the sales associate paying $320."
Hope this helps!
