0=(-9)
Step-by-step explanation:
4x + 7 = -2 + 4x
4x + 7 = 4x -2
subtract 7 from both sides of the equation.
simplify your answer.
subtract 4x from both sides of the equation.
simplify your answer again.
4x + 7 = 4x -2
___-7 = 4x -7
4x __ = 4x -9
__4x = 4x -9
-4x = -4x -9
__0 = -9

Los hombres adultos tienen alturas con una media de 69.0 pulgadas y una desviación estándar de 2.8 pulgadas. Encuentre la puntuación z de un hombre de 70.3 pulgadas de alto. (Redondee la respuesta con 4 decimales)
Answer:
0.4643
Step-by-step explanation:
z = (x-μ) / σ, donde
x es la puntuación bruta = 70.3 pulgadas
μ es la media de la población = 69 pulgadas
σ es la desviación estándar de la población = 2.8 pulgadas
z = (70.3 - 69) /2.8
z = 0.46429
Aproximadamente a 4 lugares decimales = 0.4643

One game had an attendance of 25,000 visitors. Based on the table, how many people out of 25,000 could be expected to buy a flag?
A.
1,375
B.
1,650
C.
3,850
D.
2,750
The number of people who could be expected to buy a flag using the expression (22/200) x 25,000 is 2,750.
Option D is the correct answer.
We have,
Based on the table,
The number of people who could be expected to buy a flag out of 25,000 visitors is:
(22/total items sold) x 25,000
To find the total items sold, you can add up the number of caps, jerseys, flags, and programs:
Total items sold.
= 68 + 19 + 22 + 91
= 200
The number of people who could be expected to buy a flag is:
(22/200) x 25,000 = 2,750
Thus,
The number of people who could be expected to buy a flag is 2,750.

The base of the triangle is 4 inches more than the length of the sides and the total the total perimeter is 64 inches. Write an equation to find the length of each side of the triangle
Answer:
Both the sides are equal to 20 inches and the base is equal to 24 inches.
b=s3= s1+4----equation 1
s1=s2----equation 2
Perimeter of the triangle = s1+s2+s3--------equation 3
Step-by-step explanation:
Let the sides be denoted by s1 and s2 . Then the base is denoted by b=s3= s1+4----equation 1
According to the statement s1=s2----equation 2
Perimeter of the triangle = s1+s2+s3--------equation 3
64= s1+s2+ s1+4
64 = 3s1+4
60= 3s1
20 = s1
Both the sides are equal to 20 inches and the base is equal to 24 inches.

Can someone help me I’m stuck and I don’t get it
Answer:
The first one (highlighted one)
Step-by-step explanation:
The answer is the one selected. When multiplying and subtracting numbers, you do the combination that is multiplying before you subtract-unless there are numbers in parenthese. You work parentheses first. In all of the other options, you are multiplying first so not subtracting from 3. For example the second option, you would multiply 4x7 BEFORE you subtract from 3 which doesn’t work. You are also multiplying first in options 3 and 4.

What is the surface area of the rectangle below?
Step-by-step explanation:
First, we must take into account that there will be 3 pairs of sides that are the same. Starting at the front, we have 9 * 12. Since the rectangular prism is measured in units squared, this side is 108 units squared. The opposite side is the same. Our current total is 216 units. The side is 15 * 9. This is 135 units, multiplied by 2 since it has the other side, to get 270 units. Our current total is 486 units, so it already can't be A. The top and bottom sides are 15 * 12 units, giving us 180 on each, 360 in total. 360 plus 486 = 846 units squared.
A population of 2500 frogs increases exponentially at an annual rate of 25%. Which equation below best represents the population (P) in t years?
P=2500(0.25)^t
P=2500+0.25t
P=2500(0.75)^t
P=2500(1+0.25)^t
Answer:
P=2500(1+0.25)
Step-by-step explanation:
Given data
Initial population= 2500
Rate= 25%
The exponential increase is described using the expression
P=A(1+r)^t
Hence the correct representation is
P=2500(1+0.25)
