Answer:
17
Step-by-step explanation:
Remember to solve by the order by operations, or PEMDAS. PEMDAS says that when simplifying an expression, you need to solve parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right) in that order.
1) Knowing this, start by solving what's in the parentheses:
[tex]4(5-2)2-7\\= 4 (3)2-7[/tex]
2) Then - still following the order of operations - multiply the 4, 3, and 2 together.
[tex](4)(3)(2)-7\\(24)-7[/tex]
3) Finally, subtract 7 from 24.
[tex]24-7\\= 17[/tex]
Therefore, 17 is the answer.

What is the midpoint of the segment shown below? (-1,5) (-6,-2)
Answer:
(-7/2, 3/2)
Step-by-step explanation:
picture below ;)
A line became by joining two coordinates, the midpoint of the given line segment is (-3.5,1.5).
What is a line segment?
A line segment is become by joining two points which has specific coordinates.
To find the midpoint coordinate between any two points then we have to add the x's coordinates and divide by two and similarly y's coordinates and divide by two.
For example, if you have two points as (a,b) and (c,d) then the coordinate of the midpoint joining this line will be ( [tex]\frac{a+c}{2}[/tex], [tex]\frac{b+d}{2}[/tex] ).
Since the points are (-1,5) (-6,-2) so the midpoint joining this line segment will be
( [tex]\frac{-6-1}{2}[/tex], [tex]\frac{5-2}{2}[/tex] ) so (-3.5,1.5) will be the midpoint of the line segment.

PLEASE HELP ILL OFFER MONEY I DONT CARE PLEASSEEEEE Mark has $75 to spend on salmon at $5.00 per pound and/or chicken at $3.00 per
pound. If he buys s pounds of salmon and c pounds of chicken, the equation 5s + 30
= 75 must be satisfied. How much salmon did Mark buy if he bought 5 pounds of
chicken?
a) 12 lb
Ob) 16 lb
C) 17 lb
d) 19 lb
Answer:
a) 12 lb
Step-by-step explanation:
First we find the lb for the chicken
5 * $3 = $15
Then we subtract it from the total amount of money Mark has
75$ - $15 = $60
Mark has 60$ remaining to spend on salmon
60 divided by 5 = 12
So he can buy 12 lb of salmon

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a small petting zoo has Llamas and Kangaroos. There are 120 legs and 47 heads on this farm.
The equations will be formed as,
4L + 2K = 120
L + K = 47
Solve the above equations by elimination method,
4L + 2K = 120
-4L -4k = -188
____________
0 - 2K = -68
K = 34
The number of the Lamas will be,
L + K = 47
L = 47 - K
L = 47 - 34
L = 13

Year = x
Weight (kg) = y
Rate of change between 2010 and 2011 = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Where,
[tex] (2010, 35) = (x_1, y_1) [/tex]
[tex] (2011, 30) = (x_2, y_2) [/tex]
Plug in the values
[tex] = \frac{30 - 35}{2011 - 2010} [/tex]
[tex] = \frac{-5}{1} = -5 [/tex]
Rate of change = -5kg per year
This means that there was a decrease in the weight of the winning dog form 2010 to 2011 by 5 kilograms
The scale factor of the two shapes is 0.5 (or 1/2). True or false? B 32.4 km W 36 km 18 km True False
Answer: True
Step-by-step explanation:
The scale factor between shapes is the number that when multiplied by the dimensions of the original shape will give the dimensions of the transformed shape.
Likewise when the dimensions of the transformed shape is divided by this number, it will yield the dimensions of the original shape.
The original shape has a length of 36km.
= 36 * 0.5
= 18 km
This proves that 0.5 is the scale factor because when the length of the original shape was multiplied by it, the result was the length of the transformed shape.
A park started with 12 oak trees, and the number of oak trees increased at a rate of 25% each year. Write the function that models the situation, substituting numerical values for A and r into the expression.
f(x)=A(1+r)X
Answer:
[tex]f(x) = 12(1.25)^{x}[/tex]
Step-by-step explanation:
The number of oak trees after x years is given by a function in the following format:
[tex]f(x) = A(1+r)^{x}[/tex]
In which A is the initial number of oak trees, and r is the growth rate, as a decimal.
A park started with 12 oak trees
This means that [tex]A = 12[/tex]
The number of oak trees increased at a rate of 25% each year.
This means that [tex]r = 0.25[/tex]
So
[tex]f(x) = A(1+r)^{x}[/tex]
[tex]f(x) = 12(1+0.25)^{x}[/tex]
[tex]f(x) = 12(1.25)^{x}[/tex]
