Answer:
-56
Step-by-step explanation:
Let the said number be x, so
x / -8 = 7
That's the equation
On solving further, we cross multiply to have
x = -8 * 7
x = -56
That means the number is -56

The library is having a book sale. Hardcover books sell for $4 each, and paperback books are $2 each. If Ayanna spends $26 for 8 books, how many hardcover books did she buy?
Answer:
5 hardcover books
Step-by-step explanation:
x + y = 8 ↔ Assume x for hardcover books and y for paperback cover
4x + 2y = 26 ↔ Total cost of 8 books is $26
-2x - 2y = -16 ↔ Multiply Equation 1 by -2 so that the coefficients of y is opposite
2x = 10 ↔ Add the two equations to eliminate y
x = 5 ↔ Divide each side by 2

HELP ASAPPP PELASEEEEE
Answer:
10π cm
Step-by-step explanation:
We require to find the radius (r) of the circle
The area (A ) is calculated as
A = πr² = 25π ( divide both sides by π )
r² = 25 ( take the square root of both sides )
r = [tex]\sqrt{25}[/tex] = 5
The circumference (C) is calculated as
C = 2πr = 2π × 5 = 10π cm

List the steps to solve the fol
lowing equation:
5x - 6 = 44. Then solve for x
Answer:
x = 10
Step-by-step explanation:
Simplifying
5x + -6 = 44
Reorder the terms:
-6 + 5x = 44
Solving
-6 + 5x = 44
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 5x = 44 + 6
Combine like terms: -6 + 6 = 0
0 + 5x = 44 + 6
5x = 44 + 6
Combine like terms: 44 + 6 = 50
5x = 50
Divide each side by '5'.
x = 10
Simplifying
x = 10

Margaret deposits $1,000 in a savings account that pays 1.4% interest compounded
semiannually. What is her balance after 1 year?
Answer:
The balance after 1 year is;
$1,014.05
Step-by-step explanation:
To do this, we use the compound interest formula
That will be ;
A =P (1 + r/n)^nt
A is the amount generated which we want to calculate
r is the rate = 1.4% = 0.014
P is the amount deposited = $1,000
n is the number of times it is compounded annually which is 2 (semi-annually means 2 times in a year)
this the number of years which is 1
we have this as:
A = 1,000( 1 + 0.014/2)^(2*1)
A = 1,000(1 + 0.007)^2
A = 1,000(1.007)^2
A = $1,014.05

In ΔPQR, p = 220 inches, q = 890 inches and ∠R=121°. Find the length of r, to the nearest inch.
the value of r will be 970 inches Approx.
What are the properties of Triangle?The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
Given, In ΔPQR, p = 220 inches, q = 890 inches and ∠R=121°.
From the general formula of side of triangle:
c² = a² +b² - 2ab * cos ∠C
In Our case,
a = p = 220
b = q = 890.
c = r
∠C = ∠R = 121 degrees
Thus,
r² = 220² + 890² - 2*220*890 * cos 121°
r² = 941344.455067
r = 970.229073501
r = 970 inches Approx.
Therefore, the value of r will be 970 inches Approx.

Answer:
radius=6
Step-by-step explanation:
arc ACB=6xPi
Pi=3.14159
arc ACB=18.85 (rounded to 2 places)
ACB is a half circle so a full circle would be 18.85x2 or 37.7
circumference (whole circle)=2 x Pi x radius
37.7=2 x 3.14159 x radius
radius= 37.7/(2 x 3.14159)

Chris had 30 minutes to do a three-problem quiz. He spent 11 3/4 minutes on question A and 4 1/2 minutes on question B. How much time did he have left for question C?
Answer:Chris spent 13 3/4 minutes on question C
Step-by-step explanation:
First let's write an equation:
We know 30 is the total and we are trying to find a part, and 11 3/4 is a part and 4 and 1/2 is a part
So:
30=11 3/4 + 4 1/2 + x
30=16 1/4 + x
- 16 on both sides(to find what x equals to)
13 2/4=x
X=13 3/4
