In a game, players have 60 seconds to toss rings into boxes.
Rings that land in green boxes, g, earn 5 points
Rings that land in blue boxes, b, earn 10 points
Players must earn at least 50 points to win
Which inequality models the combination of tosses needed to win?
Answer: g*5 + b*10 ≥ 50.
Step-by-step explanation:
Let's define g = number of rings that land in green boxes.
and b = number of rings that land in blue boxes.
For each ring in the green box you earn 5 points, then if there are g rings in the green box, you have g*5 points.
And for the blue is similar, if there are b rings in the blue box, you will have b*10 points.
Then the total number of points that you will get is:
T = g*5 + b*10.
And the minimum that you need to win is 50 points, the inequality will be:
T ≥ 50
or
g*5 + b*10 ≥ 50.
24 POINTS.
(U also have to explain the reasoning you used to find the value of P)
9514 1404 393
Answer:
P = 70 +4x
Step-by-step explanation:
From your previous work with the parking lot, you know its area is ...
A = 560 +32x
The width of the parking lot extension is (52 -20 -24) = 8 yards, so its area is ...
extension area = 8P
We want the extension area to be equal to the original area so that adding the extension will double the area:
extension area = A
8P = 560 +32x
P = 70 +4x . . . . . . divide by 8
What is the value of b? b+4 b+38 b-19
Answer: For the first one b can be a higher or lower number
for the second one b can be a higher or lower number and the last one must be a higher number

If amna bought 1/3 pounds of sausages on Sunday and 2/5 of Turkey on Monday. How much more Turkey did she buy ?
Answer:
1/15
Step-by-step explanation:
1/3=5/15
2/5=6/15
6/15-5/15=1/15
PLEASE GIVE BRAINLIEST
Answer:
Amna bought 1/15 pounds of turkey more on Monday than she bought on Sunday.
Step-by-step explanation:
Turkey bought on Sunday = 1/3 pounds
Turkey bought on Monday = 2/5 pounds
2/5 - 1/3
= 6/15 - 5/15
= 1/15

Brainliest to right answer also based on answer 1 are the equations equivalent?
Answer:
Yes, they are equivalent, and the second question is B
Step-by-step explanation:
If you add x on both sides of equation A, then it comes up to 5x+2=6, which is equivalent to equation B. For the second question, you are just basically adding a variable to each side, so it is B.

PLS HELP I WILL HELP BACK 15 POINTS WILL GIVE BRAINLIEST Write the equation of a polynomial, in standard form, that has:
Zeros: 3, -2/5, 3i
leading coefficient of -5
Answer: -5x^3 -13x^2 -6x + 15ix + 39ix + 18i
Step-by-step explanation:
An equation with zeros at these numbers could be put in form x = number.
So, (x-3) could be set to 0 to get x=3.
So, you can look at these "answers" they give you and work backward to get:
(x-3)(x+2/5)(x-3i)
Multiply first two together.
x^2+2/5x-3x-6/5
simplify
x^2 - 2 3/5x -6/5
Change first term to have same denominator by multiplying by "1" in the form of -5/-5
-5x^2/-5 - 13/5x -6/5
Divide all terms by 1/5 (which is the same as multiplying each term by 5)
(-5x^2 -13x -6)
Now multiply by (x-3i)
-5x^3 -13x^2 -6x + 15ix + 39ix + 18i
Use substitution to solve each system of equations.

16x - 4y = 18
x = -6y - 7
When you use the substitution method you need to plug a value into the corresponding variable of another equation.
In this occasion,"-6y-7" can be plugged into the x of "16x-4y=18" because it represents the x.
16(-6y-7)-4y=18
Distribute 16 into the parentheses
-96y-112-4y=18
Combine like terms
-96y-4y-112+112=18+112
-100y=130
Divide by -100 to get y by itself
y=-1.3 or -13/10
Now plug the y into any equation...I chose "x = -6y - 7" but it doesn't matter
x= -6(-1.3)-7
x=-14.8 or 4/5
Answer:
Step-by-step explanation:
1. 16x-4y=18
4x-9/2:2x+9/8
4x-9/2:m=4
y=4x-9/2
2. x=-6y-7

What is the interval?
Find the total interest:
$520 at 2%
for 6 years
The interest is %2 of 520 which, if you do the math, is 10.4 cents. You want to find out how much interest it is for 6 years so you have to multiply them.
10.4 x 6 = 62.4
The total interest for 6 years is $62.4

Express 4/10 as a decimal number, and identify another decimal number that is equal to it. 4/10 expressed as a decimal number is ___, which is equal to ___
Answer:
Step-by-step explanation:
Decimal number in mathematics is one in which the whole number and the fractional part is separated by a decimal point
If we divide 4 by 10 it will give us a a decimal number which was done below
4/10
=0.4
And also if we divide 40 by 100 we will still have a decimal of 0.4
0.4=40/100
Express 4/10 as a decimal number, and identify another decimal number that is equal to it. 4/10 expressed as a decimal number is 0.4 which is equal to _40/100__

If solving a system of linear equations by elimination or substitution I get that 2=3, it means (check all that apply)
If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutions
If the system of equations is 3 linear equations in 3 variables, there is infinity number of solutions
If the system of equations is 2 linear equations in 2 variables, the system has no solutions
If the system of equations is 3 linear equations in 3 variables, the system has no solutions
Answer:
If I get 2=3 in solving the system, it means the following:
If the system of equations is 2 linear equations in 2 variables, the system has no solutions If the system of equations is 3 linear equations in 3 variables, the system has no solutionsStep-by-step explanation:
The solution of linear system of equations implies that a point has to be found that holds true on all equations involved.
The system may consist of two equations involving two unknowns or may consist of three equation with three unknowns.
When a system of equation has no solution, the variables are removed in solving the equations and we get an equation or values in the form.
constant = constant
So,
If I get 2=3 in solving the system, it means the following:
If the system of equations is 2 linear equations in 2 variables, the system has no solutions If the system of equations is 3 linear equations in 3 variables, the system has no solutions
