Answer: 35
Step-by-step explanation:
Alright, so to start with, we have the equation you gave: 4x-5.
Since x = 10, we can replace x with 10 in this equation, so it becomes 4 x 10 - 5.
Using BEDMAS (Brackets, Exponents, Division, Multiplication, Addition, Subtraction), we start with the multiplication first, so since 4 x 10 = 40, we go from (4 x 10) -5, to 40 - 5
And now moving on to subtraction, 40 - 5 = 35. Hope this helps!

The tape diagram represents the ratio of the numbers of planets in two different solar systems. There are 8 planets in Solar System B. How many planets are in Solar System A?
Answer:
I got 6
Step-by-step explanation:
SO basically, we know solar system b has 8 planets, and there are eight bars. I divided 8 by 4 to get 2, which is the amount of planets in every bar. Then I saw solar system a has 3 bars, and multiplied 2 x 3 to get 6 planets in solar system a.
hopes this helps!
Evaluate f(x) = 8-3x, when f(4) +9
A. f(4) +9=5
B. f(4) +9= -13
C. f(4) +9= -10
D. f(4) +9= 29
Answer:
A
Step-by-step explanation:
f(x) = 8 - 3x
f(4) = 8 - 3(4) = -4
-4 + 9 = 5

Liz wanted to buy a new book. When she checked the price last week, it was $19. This week, the same book was listed for $22. Write and solve an equation to show how much the book increased in price.
22 = p + 19; p = $3
22 = p − 19; p = $41
19 + p = 41; p = $22
2p = 22; p = $11

Three different recipes each make a different number of cookies and require a different amount of flour.
Recipe 1: 1 dozen cookies; 1 cup of flour
Recipe 2: 3 dozen cookies; 3.5 cups of flour
Recipe 3: 5 dozen cookies; 6 cups of flour
Determine if the three recipes use a proportional amount of flour.
Yes, it is proportional because the ratios between the number of cookies and cups of flour are all equivalent.
Yes, it is proportional because the cookies increase by 2 dozen for every 2.5 cups of flour.
No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
No, it is not proportional because the number of cookies and cups of flour could not be zero at the same time.
The correct statement is (C) No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that:
Three different recipes each make a different number of cookies and require a different amount of flour.
From the recipe:
The ratios of the number of cookies to the number of cups of flour:
For recipe 1:
= 12/1 = 12
For recipe 2:
= 36/3.5 = 10.28
For recipe 3:
= 60/6 = 10
No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
Thus, the correct statement is (C) No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.

Question
Evaluate.
−[−1 1/5÷0.6(1.3)]−5/6
What is the value of the expression?
Enter your answer as a simplified mixed number in the box.
Answer:
−[−1 1/5 ÷ 0.6(1.3)] − 5/6
First, let's simplify the expression within the square brackets:
−1 1/5 ÷ 0.6(1.3)
To simplify this, let's convert the mixed number to an improper fraction:
−6/5 ÷ 0.6(1.3)
Next, we multiply 0.6 by 1.3:
−6/5 ÷ 0.78
To divide fractions, we can multiply by the reciprocal:
−6/5 * (1/0.78)
Now, let's multiply the numerators and denominators:
-6/5 * 1/0.78 = -6/5 * 1/0.78 = -6/3.9
To simplify this fraction, we can multiply both the numerator and denominator by 10 to eliminate the decimal:
-6/3.9 * 10/10 = -60/39
Now, let's simplify the expression further:
−60/39 − 5/6
To add or subtract fractions, we need a common denominator. In this case, the least common multiple (LCM) of 39 and 6 is 78:
−60/39 − 5/6 = −(60/39 * 2/2) − 5/6 = −120/78 − 5/6
Now, we can combine the fractions:
−120/78 − 5/6 = (−120 * 6)/(78 * 6) − 5/6 = −720/468 − 5/6
To subtract the fractions, we need a common denominator:
−720/468 − 5/6 = −720/468 − (5 * 78)/(6 * 78) = −720/468 − 390/468
Now, we can combine the fractions:
−720/468 − 390/468 = (−720 − 390)/468 = −1110/468
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 78:
−1110/468 = (−1110 ÷ 78)/(468 ÷ 78) = −15/6
The simplified fraction is −15/6.
However, the question asks for the value as a simplified mixed number. To convert the fraction to a mixed number, we divide the numerator by the denominator:
−15 ÷ 6 = −2 remainder 3
Therefore, the value of the expression is -2 3/6, which can be further simplified as -2 1/2.
So, the value of the expression is -2 1/2.

Which expression is equivalent to 7/8 divided 1/3
easy points
why isn't m^3=512 ±8, but just 8? I went onto 2 diff websites and the answer book (yes i have an answer book) and it says 8.
Because of that, when do you add ± in questions like the ones on top? (take into account units and no units, thanks)
i'm confusion
Also, why do you need (x) in questions like (-7)^3? I feel like there is no point, especially when it is just one problem.
Answer: It is only +8 because it is an odd power, so you're only multiplying 3 numbers together and not 2 or 4 and so on. Any odd power is always only going to have 1 answer because if you try the other one then it comes out to be the opposite.
You only need the parenthesis if you want to plug it into a calculator because -7 in a calculator is taken as subtracting 7 while (-7) is taken as a negative 7. They are just building good habits early.

The veterinarian told Sally that her cat needs to lose 5 pounds. A healthy weight loss for her cat would be about 1 pound every 2 weeks. To model this situation, she graphed the following line, where y represents the number of pounds left to lose and x represents time in weeks.
The equation for this line is y =___ x + ___ . If she continues the line, she would see that it would take___weeks for her cat to lose 5 pounds
Answer:
You already know the answer, but anyway it's 10 weeks with y = 0,5x + 0
Step-by-step explanation:
Basically what you have to do to find the equation is to pick 2 random points on the line drawn to get the solution.
I take (0, 0) and (2, 1) because they are the simplest ones.
The equation for finding a line with 2 points (that actually are 4 coordinates x1 = 0, y1 = 0, x2 = 2 and y2 = 0) is:
(x + x1) \ (x2 + x1) = (y + y1) \ (y2 + y1)
that becomes:
(x + 0) \ (2 + 0) = (y + 0) \ (1 + 0)
simplyfing this, it becomes:
x/2 = y ---> y = 1/2x that you can write on the answer page as y = 0,5x + 0
Answer: The equation for this line is y = -1/2 x + 5. If she continues the line, she would see that it would take 10 weeks for her cat to lose 5 pounds.
