Answer:3)is $12
4)is $14
Step-by-step explanation:
Cost price=$20=100%
New price percent =100-40=60%
New price=60/100×20
=$12
Tax added selling price=60%+10%
=70/100×$20
=$14

what does 1/7 estimate to 0,1/2,1
Answer:
Estimating sums and differences of fractions to the nearest 1/2 · Fractions < 1/4 are rounded down to 0 · Fractions ≥ 1/4 and ≤ 3/4 are rounded to 1/2 · Fractions > 3
Step-by-step explanation:
Answer:
Well, if you have 1/7 and you can round to 0,1/2 or 1 and sense Ur fraction is less than 4 that means you would round to 0
Step-by-step explanation:
Solve the Quadratic Equation: 2(x - 5)^2 = 18
Answer:
x=2 or x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x2−20x+50=18
Step 2: Subtract 18 from both sides.
2x2−20x+50−18=18−18
2x2−20x+32=0
Step 3: Factor left side of equation.
2(x−2)(x−8)=0
Step 4: Set factors equal to 0.
x−2=0 or x−8=0
x=2 or x=8
Answer:
1. x = 8
2. x = 2
Step-by-step explanation:
2 • (x - 5)2 - 18 = 0
2.1 Evaluate : (x-5)2 = x2-10x+25
3.1 Pull out like factors :
2x2 - 20x + 32 = 2 • (x2 - 10x + 16)
3.2 Factoring x2 - 10x + 16
The first term is, x2 its coefficient is 1 .
The middle term is, -10x its coefficient is -10 .
The last term, "the constant", is +16
Step-1 : Multiply the coefficient of the first term by the constant 1 • 16 = 16
Step-2 : Find two factors of 16 whose sum equals the coefficient of the middle term, which is -10 .
-16 + -1 = -17
-8 + -2 = -10 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and -2
x2 - 8x - 2x - 16
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-8)
Add up the last 2 terms, pulling out common factors :
2 • (x-8)
Step-5 : Add up the four terms of step 4 :
(x-2) • (x-8)
Which is the desired factorization
2 • (x - 2) • (x - 8) = 0
4.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Alani receives a collection of coins from her mother as a gift. She wants to start collecting coins. She
projects the total number of coins she believes she will own over the next 5 years and graphs the
results.
The graph shows the relationship between the number of

Which pair of measurements is not equivalent?
A. 4 tons, 6,000 lb.
B. 5 lb., 80 oz.
C. 160 oz., 10 lb.
D. 14,000 lb., 7 tons
Answer:
A
Step-by-step explanation:
1 ton is equal to 2,000lbs. So if you multiply 4 and 2,000 you should end up with 8,000lbs, not 6,000lbs.

Answer:
6 pack = $7.70
18 pack=$23.10
Answer:
Step-by-step explanation:
d,
7.70 * 3 = 23.10
because 6 goes into 18 ,times.
