1. x - 2y = 14
x + 3y = 9
2. y = 2x
5x - y = 9
Answers
Answer:
Step-by-step explanation:
x - 2y = 14
x + 3y = 9
subtract the first equation from the second to eliminate the x terms:
x + 3y = 9
-x + 2y = -14
-----------------
5y = -5
y = -1
x - 2(-1) = 14
x = 12
:::::
y = 2x
5x - y = 9
Substitute 2x for y in the second equation?:
5x - 2x = 9
3x = 9
x = 3
y = 6

What is the general equation of a Straight line?The general equation of a straight line is -
y = mx + c[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a graph as shown in the figure.
We can find the slope using a pair of coordinates. Let the two points be -
(50, 125) and (100, 250)
The slope will be -
m = (250 - 125)/(100 - 50)
m = 125/50
m = 2.5
Therefore, the slope of the graph is 2.5 and it represents the profit earned for each box of cookies sold.

Answers
Step-by-step explanation:
.05N + .10D = 1.65
.05 is the value of the nickel and .10 is the value of the dime.
N + D = 21 because you have some combination of them that total 21
solve for N: N = 21- D
substitute into the first equation
0.5 (21-D) + .10D = 1.65
1.05 - .05D + .10D = 1.65
.05D = .6
D = 12 you have 12 dimes
21-12 = 9 nickels

14/1 = x/1.99 what is this awnswer
Answers
Answer:
x = 27.86 thats the answer
Answer:
0.2786
Step-by-step explanation:
Solution Steps:
The following question is of the type "How much X percent of W", where W is the whole amount and X is the percentage figure or rate".
Let's say that you need to find 14 percent of 1.99. What are the steps?
Step 1: First determine the value of the whole amount. We assume that the whole amount is 1.99.
Step 2: determine the percentage, which is 14.
Step 3: Convert the percentage 14% to its decimal form by dividing 14 into 100 to get the decimal number 0.14: 14100 = 0.14
Notice that dividing into 100 is the same as moving the decimal point two places to the left. 14.0 → 1.40 → 0.14
Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount: 0.14 x 1.99 = 0.2786 (answer).
The steps above are expressed by the formula: P = W × X% 100. This formula says that: "To find the portion or the part from the whole amount, multiply the whole by the percentage, then divide the result by 100". The symbol % means the percentage expressed in a fraction or multiple of one hundred.
