Answer:
Add -3+8
Step-by-step explanation:
You would do this first because it is in the brackets. Usually you would do (*) first but those are just there because the 4 is negative and if they were not there it would get confusing and look like this::[-3+8]--4. So the next step would be the [*].
HOPE THIS HELPS!!!
Answer:
Use PEMDAS
Step-by-step explanation:
Parenthesis, If there are none move on to exponents if there are no exponents move to multiplication. No multiplication? use division. If you dont see division use addition and lastly if there is no addition use subtraction. In the equation, it looks like you have to make the -3 and 8 positive. So, since the -4 is in the parenthesis(P) multiply(M) 4 by 3 and 8 once the three is positive. So your final answer would be either C or D

4.5 times what equals 5
Answer:
REEEEEEEEEEEEEEEEEEEEE
Step-by-step explanation:
i thnk that the answer is .9333 !!
The 4.5 times 10/9 equals 5. In other words, if you multiply 4.5 by 10/9, you get the value of 5.
To find the number that, when multiplied by 4.5, equals 5, we can set up an equation and solve for the unknown number.
Let's represent the unknown number as 'x':
4.5 * x = 5
To isolate 'x', we need to get rid of the coefficient 4.5. To do that, we'll divide both sides of the equation by 4.5:
x = 5 / 4.5
Now, perform the division:
x = 1.111...
The result is a repeating decimal, which means the number that satisfies the equation is 1.111... (with 1 repeating indefinitely).
To express the result more precisely, we can write it as a fraction:
x = 5 / 4.5 = 10 / 9
Therefore, 4.5 times 10/9 equals 5. In other words, if you multiply 4.5 by 10/9, you get the value of 5.

You add 4 drops of food coloring to 2 cups of white frosting and get the orange frosting above. Francisco wants his frosting to be the same color as yours, but he has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add.
Answer:
Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting
Step-by-step explanation:
4 drops of food coloring to 2 cups of white frosting and get the orange frosting.
He has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add
Let x = drops of food coloring he will add
Drops of food coloring : cups of white frosting
4 : 2 = x : 5
4 / 2 = x / 5
Cross multiplication
4 * 5 = 2 * x
20 = 2x
Divide both sides by 2
x = 20 / 2
= 10
x = 10 drops of food coloring
Therefore, Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting

The owners of a golf course hired a company to determine how many squirrels were living on their property. First, the company put marks on 22 squirrels. Later, the company returned and counted a total of 220 squirrels, of which 11 were marked. To the nearest whole number, what is the best estimate for the squirrel population?
Answer:
Squirrel population is 440 squirrels.
Step-by-step explanation:
It is given that there are 22 squirrels are marked.
Later the company returned and counted a total of 220 squirrels of which are marked were 11.
So, we can set up proportional equation to find the squirrel population.
Let squirrel population is x.
We can set up proportional equation as
[tex]\frac{11}{220}=\frac{22}{x}[/tex]
Cross multiply
11 x=4840
Divide both sides by 11
x=440
Best estimate is 440.

Find the value of X in the triangle shown below.
Answer:
x = 33°
Step-by-step explanation:
All angles in a triangle add up to 180°.
Step 1: Set up equation
x + 114 + 33 = 180
Step 2: Solve for x
Combine like terms: x + 147 = 180Subtract 147 on both sides: x = 33Foster is centering a photo that is 1 1/2 inches wide on a scrapbook page that is 16 inches wide. How far from each side of the page should he put the picture? Enter your answer as a mixed number.

Step-by-step explanation:
A kilogram of potatoes cost $25.A dozen bananas cost $40.
a) Write an algebraic expression for the total cost of n kilograms of potatoes and one dozen bananas.
b) Evaluate your expression to determine the cost of 15kg of potatoes and one dozen bananas
Answer:
a) T = 25n + 40
b) T = $415
Step-by-step explanation:
The total cost of 'n' kilograms of something can be expressed as 'n' multiplied by the cost, since it is a constant cost per unit. Therefore the price for n kg of potatoes can be expressed as 25n. We are also told that a dozen bananas cost $40, so our expression is the cost of potatoes added to the cost of bananas. So, is we use 'T' for total cost, our expression will look like this:
T = 25n + 40
Now we can use this expression to find the cost of 15kg of potatoes and the same amount of bananas. We can do this by simply substituting the given amount for n:
T = 25(15) + 40
T = 375 + 40
T = $415
The cost of 15kg of potatoes and one dozen bananas is $415.

Answer:
a=9/100 b= 7/20
Step-by-step explanation:
For a all you do is take the 9 out of the 100 in 1.
For b, all you do is take the 35/100, and then simplify it, so in this case it is 7/10 if you divide both the numerator and denominator by 5.
So a = 9/100 and b = 7/20
If α , β are roots of x2 + 5x + a =0 and 2α + 5β = -1 then α is equal to _____?
9514 1404 393
Answer:
-8
Step-by-step explanation:
If α and β are roots of x^2 +5x +a = 0, then we must have ...
(x -α)(x -β) = x^2 +5x +a
x^2 -(α+b)x +αβ = x^2 +5x +a
Then ...
α + β = -5
Together with the other relation between the roots, we have a system of equations in α and β.
Using the above to write an expression for β, we get ...
β = -α -5
Substituting this into the given relation, we have an equation for α:
2α +5(-α -5) = -1
-3α -25 = -1 . . . . . . eliminate parentheses
-24 = 3α . . . . . . . . add 3α +1
-8 = α
The root α is equal to -8.

<PQR=134
<SQR=46
Answer:
[tex]\boxed {\angle PQR = 134\textdegree}[/tex]
Step-by-step explanation:
Both angles are Supplementary (Two angles that add up to 180°). So, write an expression using the following measurements of both [tex]\angle PQR[/tex] and [tex]\angle RQS[/tex] and 180:
[tex]\angle PQR = 3x + 5[/tex]
[tex]\angle RQS = x + 3[/tex]
[tex]3x + 5 + x + 3 = 180[/tex]
Solve:
[tex]3x + 5 + x + 3 = 180[/tex]
[tex]4x + 5 + 3 = 180[/tex]
[tex]4x + 8 = 180[/tex]
[tex]4x + 8 - 8 = 180 - 8[/tex]
[tex]4x = 172[/tex]
[tex]\frac{4x}{4} = \frac{172}{4}[/tex]
[tex]x = 43[/tex]
-After you have the value of [tex]x[/tex], use it to the expression of [tex]\angle {PQR}[/tex] to get the actual answer of [tex]\angle PQR[/tex]:
-The value of [tex]x[/tex]:
[tex]x = 43[/tex]
-Solve for the measurement of [tex]\angle PQR[/tex]:
[tex]3x + 5[/tex]
[tex]3(43) + 5[/tex]
[tex]129 + 5[/tex]

(a)If a t-shirt costs Rs. 375, what will be the total cost of the t-shirts for the team?(b)A sponsor agrees to pay Rs. 7020 out of the total cost of the t-shirts. The balance amount will be paid by each player. How much will be paid by each player?
Answer:
Rs. 210Step-by-step explanation:
Given that a t-shirt cost Rs. 375,
then 2 t-shirt will cost Rs. 375*2
=Rs.750
a. the total cost will be
13*750
=Rs.9750
b. a sponsor pays Rs.7020
there will be a deficit of
9750-7020
=2730
since there are 13 players each player will pay
2730/13
Rs. 210
