Answer:
20 cats
Step-by-step explanation:
A proportion has to be setup to answer this
5/4 = 25/x
x represents the missing number of cats
This fraction represents the relationship amongst dogs and cats
----
To solve cross multiply
5x = 100
(let me down below if you need an explanation on how to cross multiply)
Divide both sides by 5 in order to get the variable by itself
100/5 = 20
x = 20
The shelter has 20 cats

(x+1)-6(x+1)+8 how to factorise it?
Answer:
Step-by-step explanation:
If you have written the question correctly, then you don't need to factor it. You only need to remove the brackets.
x + 1 + 6x + 6 + 8
7x + 15 is your final answer.
However, I think the question is
(x + 1)^2 + 6(x + 1) + 8
Let y = x + 1
y^2 + 6y + 8
(y + 2)(y + 4)
(x + 1 + 2 ) ( x + 1 + 4)
(x + 3)(x + 5)
4 less than y is greater than 5
Answer:
Step-by-step explanation:
The equation would be: y-4>5

A sports store is having a 20% off sale on skis. The original price of the ski is $560.00
The tax rate is 8.5%. What is the total cost of the skis?
Answer:
Total cost: 486.080$
Step-by-step explanation:
Original Price: 560.000$
Sale: 20%
Discount: 560.000$ * 20% = 112.000$
Discounted Price: 560.000$ - 112.000$ = 448.000$
Tax Rate: 8.5%
Tax: 448.000$ * 8.5% = 38.080$
Tax after Tax: 448.000$ + 38.080$ = 486.080$

O DE=2AC
Om BCA = 2(m_BED)
O DE = AC
DEI|AC
Answer:
DE is parallel to AC
DE = 2AC
ExplanationIn triangle ABC, BD = AD
BE = EC
D is mid point of AB
E is the mid point of AC
According to the mid point theorem, ( The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.”) DE is parallel to AC and equal to half of it
Answer:
For clarification, the answer is DE||AC or in other words, DE is parallel to AC.

Answer: Good luck guys
a) 4(9 x - 18) > 3(8x + 12)
The solution to the inequality is x > 9.
Graph A.
b) -1/3 (12x + 6) ≥ -2x + 14
The solution to the inequality is x ≥ -8.
Graph B.
c) 1.6 (x + 8) ≥ 36.4
The solution to the inequality is x ≥ 14.75.
Graph C.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
a)
4(9x - 18) > 3(8x + 12)
First, we can simplify both sides of the inequality:
36x - 72 > 24x + 36
Next, we can isolate the variable on one side by subtracting 24x from both sides:
12x - 72 > 36
Finally, we can isolate x by adding 72 to both sides:
12x > 108
x > 9
Therefore, the solution to the inequality is x > 9.
b)
-1/3(12x + 6) ≥ -2x + 14
First, we can simplify the left-hand side of the inequality:
-4x - 2 ≥ -2x + 14
Next, we can isolate the variable on one side by adding 4x to both sides:
-2 ≥ 2x + 14
Then, we can isolate x by subtracting 14 from both sides:
-16 ≥ 2x
Finally, we can divide both sides by 2, remembering to reverse the direction of the inequality because we are dividing by a negative number:
-8 ≤ x
Therefore, the solution to the inequality is x ≥ -8.
c)
1.6(x + 8) ≥ 36.4
First, we can simplify the left-hand side of the inequality:
1.6x + 12.8 ≥ 36.4
Next, we can isolate the variable on one side by subtracting 12.8 from both sides:
1.6x ≥ 23.6
Finally, we can divide both sides by 1.6:
x ≥ 14.75
Therefore, the solution to the inequality is x ≥ 14.75.
Thus,
a) 4(9 x - 18) > 3(8x + 12)
The solution to the inequality is x > 9.
Graph A.
b) -1/3 (12x + 6) ≥ -2x + 14
The solution to the inequality is x ≥ -8.
Graph B.
c) 1.6 (x + 8) ≥ 36.4
The solution to the inequality is x ≥ 14.75.
Graph C.

Subtract the sum of −7 and 13 from the sum of −2 and −9 *
Answer:
-17
Step-by-step explanation:
The sum of -2 and -9 is (-2) + (-9) = -2 - 9 = -11.
The sum of -7 and 13 is 13 - 7 = 6.
Hence, subtracting 6 from -11 would be -11 - 6 = -17.

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Maurice has a pet hamster. In October he burned through $13.68 on hamster food $7.89 on wood shavings and $21.14 on another hamster wheel.
Then the amount of money that he spent on his hamster will be given by the summation of $13.68, $7.89, and $21.14.
⇒ $13.68 + $7.89 + $21.14
⇒ $42.71

B) AB and A’B’ are parallel to each other.
C) AB and A’B’are perpendicular to each other.
D) AB and A’B’ intersect each other, but are not perpendicular .
Answer:
B)

all you did was move it left so the orientation never changed
Translation involves changing the position of a shape in a coordinate grid.
The statement that must be true is: (b) AB and A’B’ are parallel to each other
From the question, we have the following observations.
Line segment AB is drawnThe line is then translated 4 units left to give A'B'The above highlights imply that:
Both lines are different; this means that (a) is falseBoth lines cannot be perpendicular, because the transformation is not rotation; this means that (c) is falseBoth lines will not intersect; this means that (d) is falseHence, the correct statement is (b), because both lines will be parallel to one another.
