7(3x + 10)
Simply the expression
Make "t" the subject of the formula s=2t+5.
Answer:
t = [tex]\frac{s-5}{2}[/tex]
Step-by-step explanation:
Given
s = 2t + 5 ( subtract 5 from both sides )
s - 5 = 2t ( divide both sides by 2 )
[tex]\frac{s-5}{2}[/tex] = t

Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.
Answer:
adult tickets 6.9
children tickets 3.9
Step-by-step explanation:
3x + y = 24.60 L1
5x + 4y = 50.10 L2
5L1 - 3L2
15x + 5y = 123
-15x - 12y = -150.3
-7y = -27,3
y = -27,3/-7
y = 3.9
3x + y = 24.60
3x + 3.9 = 24.60
3x = 24.60 - 3.9
3x = 20.7
x = 20.7 / 3
x = 6.9

In a simple frequency distribution, to determine _______________, we divide the observed range by the number of intervals.
Answer:
Interval width
Step-by-step explanation:
In normal statistics, we calculate range as difference between Maximum Value and Minimum Value of the data given.
However, in group simple frequency distribution, we have what we call interval width which is simply the range of values contained in each interval.
To determine this interval width, we we divide the observed range by the number of intervals chosen.
16. The quotient of a number and -2 is the same as the sum of -4 and 10.
Answer: The number is -12
Step-by-step explanation:
The situation can be represent by the equation
[tex]\frac{n}{-2} = -4 + 10[/tex] Now solve for n by combining like terms on the right side
[tex]\frac{n}{-2}[/tex] = 6 multiply both sides by -2
n = -12

FACTOR !!!
a) 5x^2+25
b) 2x^2-3x-2
Step-by-step explanation:
(a): 5x^2 + 25 = 5 * x^2 + 5 * 5 = 5(x^2 + 5).
(b): 2x^2 - 3x - 2 = 2x^2 - 4x + x - 2
= 2x(x - 2) + 1(x - 2) = (2x + 1)(x - 2).

Convert 32% to a fraction. Make sure your answer is fully reduced.
Answer:
8/25
Step-by-step explanation:
32/100
Find what value can divide the numerator's value (32) and the denominator's value (100) into a whole number, for this problem, 4 is the value that can do this.
32/4= 8
100/4= 25
8/25
Rewrite 4 - 5 using the additive inverse and display the new expression on a number line
When you rewrite subtraction using the additive inverse, you add the opposite. That is, -5 becomes +(-5).
The appropriate choice is ...
... 4 + (−5) A horizontal number line is shown with labels from negative 8 to positive 8. A blue arrow begins at 0 and goes to 4. A red arrow begins at 4 and goes to negative 1.

HELP!! What is f(x) = 4x + 8 when x = 7
Answer:
Subtract 2 2 from 2 2 . Add x x and 0 0 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x4−2 f - 1 ( x ) = x 4 - 2 is the inverse of f(x)=4x+8 f ( x ) = 4 x + 8 .

Simplify 5(2r+1)-3(-4r+2)
Answer:
22r-1
Step-by-step explanation:
5(2r+1)-3(-4r+2) Distribute the terms
10r+5+12r-6 Combine like terms
22r-1
Answer:
5 ×( 2r +1) - 3 × ( -4r +2)

what is greather than -7
what is less than -2
Answer:
The greater than of -7 is 7. The less than -2 is 2.
Step-by-step explanation:
It's the same distance from both but, the positive number always been greater than negative number.
Both questions have an infinite number of correct answers.
Here are six numbers that are greater than -7:
-6.99999, -4, 0, 3, π, 4.00001
Here are six numbers that are less than -2:
-2.00001, -3, -π, -4, -136, -201.358

if the fraction 396/x-10 is equivalent to -22, find the value of x.
Answer: x = -8
Step-by-step explanation:
1. Miltiply x-10 on both sides: 396 = -22(x - 10)
2. Distribute -22 to (x - 10): 396 = -22x + 220
3. Subtract 220 from 396: 176 = -22x
4. Divide both sides by -22 to get x by itself: x = -8

The measure of an angle is 149°. What is the measure of its supplementary angle?
Answer: 31°
Step-by-step explanation:
Supplementary angles add up to 180 degrees so add 149 degrees to a number of degrees to get 180 degrees.That can be represent by the equation,
149 + x = 180 where x is the supplement so solve for x
-149 -149
x = 31
