let −5x+2y=14 be [1]
& y=3x+2 be [2]
Finding the value of x
By substituting y in [2] for y in [1]
⇒ −5x + 2(3x+2) = 14 [expand the bracket]
⇒ -5x + 6x + 4 = 14 [subract 4 from both sides and simplify]
⇒ x = 10
Finding the value of y
Since x =10, we can substitute value of x into [2]
⇒ y = 3(10) + 2
⇒ y = 32
How do you write 7
11
/
18
as a whole number
Answer: 8
Step-by-step explanation
Write as a decimal
7 11/18 is equal to 7.6111
Round the decimal to the nearest whole number:
If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.
If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.
Since 6 is in the tenths place we round up. 7 11/18 can be written as 8 (as whole number)
3/4 of what number equals 36 ?????????
Answer:
48
Step-by-step explanation:
This question can be written as 3/4 times a number equals 36.
To multiply by 3/4 we would times 36 and 3 and then divide by 4.
We will do the opposite to find our unknown number
36 ÷ 3 = 12
12 × 4 = 48
The number of the solution will be 48.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
3/4 of a number is equal 36.
Now,
Let a number = x
So, we can formulate;
⇒ 3/4 of x = 36
Solve for x as;
⇒ 3/4 × x = 36
Multiply by 4 as;
⇒ 3/4 × 4x = 36 × 4
⇒ 3x = 36 × 4
Divide by 3, we get;
⇒ x = 36 × 4/3
⇒ x = 12 × 4
⇒ x = 48
Thus, The number of the solution will be 48.

Find the missing amount)
Original:_______
New: 260 gallons
%increase: 30%
(not multiple choice)
Answer: 182 gallons
find 30% of 260 by multiplying 260 by 30%
260 x .3 = 78
30% of 260 = 78
Subtract 78 from 260 to get original amount
260 - 78 = 182
Original is 182 gallons
ps. this is an actual impossible question because you need to know the original amount to find what 30% of it is. What i found was a 30% decrease of 260 not a 30% increase of the original. With that being said I think this is what you want?
Answer:
Original = 200 gallons
Step-by-step explanation:
Original: x
New: 260
Percent Increase: 30%
x = 100%
New = 100% + 30%
260 = 130%
To find, original we do:
260/130 * 100 =
2 * 100 = 200

Point B (3,2)
Point C (9,6)
b. x values from A to B: 0 to 3

No, AB has a change of 3 and BC has a change of 6 in x
c. y values from A to B: 0 to 2
y values from B to C: 2 to 6
No, AB has a change of 2 and BC has a change of 4 in y
d. Calculate Slope: [tex]\frac{y{2}-y{1}}{x{2}-x{1}}[/tex]
AB (2-0/3-0) = 2/3
BC (6-2/9-3) = 4/6 = 2/3 simplified

It’s linear so you map out the first differences and then put it into y=Mx+b form. For the y gotta find the y intercept. please help
Answer:
y = 5/3x + 1
y-intercept: (0, 1)
Step-by-step explanation:
In order to determine the linear equation in its slope-intercept form, y = mx + b, where m = slope, b = y-intercept:
You need two ordered pairs from the table to solve for the slope:
We'll use (6, 11) and (9, 16).
Let (x1, y1) = (6, 11)
(x2, y2) = (9, 16)
Substitute thes values into the slope formula:
m = (y2 - y1)/(x2 - x1)
m = (16 - 11) / (9 - 6)
m = 5 / 3
Therefore, the slope of the line is: m = 5/3.
Next, we need to determine the y-intercept of the line. The y-intercept is the y-coordinate of the point (0, b ) where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
To find the y-intercept, we'll use the slope, m = 5/3, and one of the ordered pairs from the table, (6, 11). Substitute these values into y = mx + b to solve for the y-intercept, (b ):
y = mx + b
11 = 5/3(6) + b
11 = 10 + b
Subtract 10 from both sides to solve for b:
11 - 10 = 10 - 10 + b
1 = b
The y-coordinate of the y-intercept, (0, b) is 1. The y-intercept as an ordered pair is (0, 1). For the linear equation in slope-intercept form, you'll use b = 1 to write the equation.
Therefore, given the slope, m = 5/3, and the y-intercept, b = 1:
The slope-intercept form is: y = 5/3x + 1

if Point p is located on the segment between point A (1,4) and point D (7,13) . The distance from A to P is twice the distance from P to D . What are the coordinates of point P
Answer:
P (5 , 10)
Step-by-step explanation:
point A (1,4) and point D (7,13), AP/PD = 2:1
P (x,y) : x = x₁ + (a/(a+b) * (x₂-x₁)) y = y₁ + (a/(a+b) * (y₂-y₁)) .... a=2 b=1
x = 1 + 2/(2+1) * (7-1) = 5
y = 4 + 2/(2+1) * (13-4) = 10
P (5 , 10)

Answer:
The answer would be 84
Step-by-step explanation:
You divide 60 by 25 and get 2.4. Then multiply 30 by 2.4 to get 72. Finally, multiply 35 to get 84.
Hope this helps! Have a great day!! **please give me brainliest :)
Answer:
84
Step-by-step explanation:
because you did 30=72 already and you just need to find the extra 5 mins
you do 25 divided by 5 =5
60 divided by 5=12
then do 30 mins (72) + 5 mins (12) = 35 mins (72+12+84)
In a game, a player has to guess a 3-digit code in an attempt to unlock a trunk containing a prize. If the digits are to be chosen from the integers between 0 and 9 and they can be repeated, what is the probability that the player guesses the correct code on the first try?
Answer:
I think it will be 3/9=1/3
The probability that the player guesses the correct code on the first try is 0.001 or 0.1%.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
In a game, a player has to guess a 3-digit code in an attempt to unlock a trunk containing a prize.
If the digits are to be chosen from the integers between 0 and 9 and they can be repeated.
The total number of outcomes will be
Total outcomes = 10³ = 1000
The player guesses the correct code on the first try. Then the favorable event will be
Favorable event = 1
Then the probability will be
[tex]\rm P = \dfrac{1}{1000}\\\\P = 0.001\\\\P = 0.1 \%[/tex]
The probability that the player guesses the correct code on the first try is 0.001 or 0.1%.

Write each of the numbers 1, 4, 9, 16, and 25 as a base raised to the
second power. Explain why these numbers sometimes are called perfect squares
Answer:
because their principal square roots are also positive integers, square roots of numbers which are not perfect squares like 2 are irrational
step by step:
The square of a number is the number you get ehen you multiply that bumber by itself. so if n is a number then nxn = n2 is the 'square of n' it is called that because the area of a square whose edge lengh is n units is n2 square units
perfect square numbers are the numbers which are ths squares of the positive integers
ibrahim buys bags of coloured marbles blue marbles are sold in bags of 10 green marbles are sold in bags of 6 and white marbles are sold in bags of 12 ibrahim wants to buy an equal number of blue ,green and white marbles ,what is the smallest number of bags of each colour hecould buy
The smallest number of bags of each colour that he could buy is 60.
How to calculate the value?From the information, Ibrahim buys bags of coloured marbles. The blue marbles are sold in bags of 10 green marbles are sold in bags of 6 and white marbles are sold in bags of 12.
Since ibrahim wants to buy an equal number of blue ,green and white marbles, the smallest number of bags will be the lowest common multiple of the numbers. This will be:
6 = 6, 12, 18, 24, 30, 36, 42, 48, 54 and 60
10 = 10, 20, 30, 40, 50, 60
12 = 12, 24, 36, 48 and 60
