Answer:
To solve for the problem above, let x be the regular price of the shoe.
1/2x is the one-half price of the shoe then we add 6 for the pair of socks,
1/2x + 6, then lola has 32 left so we add that too, 1/2x + 6 + 32 = 75. The total amount of lola spent is 75 - 32, which is 1/2x + 6.

Answer:
Step-by-step explanation:
2) ∠A + ∠B = 146 {Exterior angle theorem}
5y + 3 + 4y + 8 = 146
5y + 4y + 3 + 8 = 146 {combine like terms}
9y + 11 = 146
9y = 146 -11
9y = 135
y = 135/9
y = 15
3) m∠A = 5y + 3
= 5*15 + 3
= 75 + 3
∠A = 78
4) m∠B = 4y + 8
= 4*15 + 8
= 60 + 8
m∠B = 68
5) m∠ACB + m∠A + m∠B = 180 {Angle sum property of triangle}
m∠ACB + 78 + 68 = 180
m∠ACB + 146 = 180
m∠ACB = 180 - 146
m∠ACB = 34
Answer:
The sum of a and (-b) is 2
Step-by-step explanation:
method 1:First, we take the negate(negative) of b to get -2. Then, we take the sum of 4 and -2 to get 2.
method 2: since adding a negative is the same as subtracting a positive, we get 4-2, which is 2.
multiplying polynomials (3m-1)(8m+7)
The product of (3m-1)(8m+7) is 24m² + 13m - 7.
To multiply the polynomials (3m-1)(8m+7), we can use the distributive property. We multiply each term in the first polynomial by each term in the second polynomial and then combine like terms.
(3m-1)(8m+7) = 3m(8m) + 3m(7) - 1(8m) - 1(7)
Simplifying this expression, we get:
24m² + 21m - 8m - 7
Combining like terms, we have:
24m² + 13m - 7
Therefore, the product of (3m-1)(8m+7) is 24m² + 13m - 7.
We can also see that this product represents a quadratic polynomial. The highest power of the variable "m" is 2, which is indicated by the term 24m². The other terms, 13m and -7, represent the linear and constant parts of the polynomial, respectively.
The result is a quadraticpolynomial in standard form, where the terms are arranged in descending order of the variable's exponent. In this case, the quadratic polynomial is 24m² + 13m - 7.
