María va de compras a una tienda departamental y adquiere los siguientes productos: 2 pantalones, 4 blusas, 3 pares de calcetas y 2 pares de tenis. El precio de los artículos por unidad es: pantalones $ 600.00, blusas: $350.00, calcetas: $120.00 y tenis: $ 950.00. Si María contaba con $5000.00, calcula cuánto dinero le sobró después de las compras realizadas.
Answers
Answer:
Pantalones = $600.00 × 2
$ 1,200.00
Blusas = $350.00 × 4
$ 1,400.00
Calcetas = $120.00 × 3
$ 360.00
Par de tenis = $950.00 × 2
$ 1,900.00
Total a pagar = $4,850.00
$5,000.00
- $4,860.00
Sobrante = $140.00
The expression (2x + a)(4x − 1) is equivalent to 8x2+ bx − 3. Find the value of b.
Answers
Answer:
b = 10
Step-by-step explanation:
Expand the left side and compare the coefficients of like terms
(2x + a)(4x - 1) ← expand using FOIL
= 8x² + 4ax - 2x - a = 8x² + x(4a - 2) - a
Compare coefficients of like terms with
8x² + bx - 3
Then a = 3 ( constant term )
b = 4a - 2 ( coefficients of the x- term )
b = 4(3) - 2 = 12 - 2 = 10
Answer:
b = 10
Step-by-step explanation:
We can break those parenthesis like this
[tex](2x + a)(4x - 1) \\ = 2x(4x - 1) + a(4x - 1) \\ = 8{x}^{2} - 2x + 4ax - a[/tex]
And then combine the terms end with x we get
[tex]8 {x}^{2} - 2x + 4ax - a \\ = 8 {x}^{2} + 4ax - 2x - a \\ = 8 {x}^{2} + (4a - 2)x - a[/tex]
Now by comparing 2 expressions, we can see that a is 3, and b = 4a-2 = 12-2 = 10

Step-by-step explanation:
Mr Hamal had Rs 4,400.He purchased 6 kg of rice at Rs 75 per kg,2packets of oil at Rs 125 per packet and he gave Rs3,300 to his wife. he divided the remaining sum between his son and daughter equally , find the share of each them
Answers
Answer: Therefore, his son and daughter got Rs 200.
Step-by-step explanation:
6 kg of rice = 75*6 = Rs 450
2 packets of oil = RS 2*125 = RS 250
now total money he spent = Rs 450 + Rs 250 + Rs Rs 3,300
= Rs 700 + Rs 3,300
= Rs 4000
Money left = Rs 4,400-Rs 4000 = Rs 400
so
400/2 = Rs 200

There is an error in step 2 where distributive property was not followed.
What is Simple interest?Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
Steps taken by the student to solve the formula of the simple interest for the values of '',
Step 1 : A = P( 1 +rt)
Step 2 : A = P + rt
Step 3 : A - p = rt
Step 4 : r = (A - P)/ t
There is an error in step 2 where distributive property was not followed.
Correct steps should be,
Step 1 : A = P( 1 +rt)
Step 2 : A = P + Prt [By distributive property]
Step 3 : A - P = Prt
Step 4 : r = (A-P)/Pt
Therefore, error was made in step 2.

A chemical company makes two brands of antifreeze. The first brand is 55% pure antifreeze, and the second brand is 80% pure antifreeze. In order to obtain 180 gallons of a mixture that contains 65% pure antifreeze, how many gallons of each brand of antifreeze must be used?
Answers
Step-by-step explanation:
the first brand = (65-55)/(80-55) x 180
= 10/25 × 180
= 72 gallons
the second brand = (80-65)/(80-55)×180
= 15/25 × 180
= 108 gallons
