What is the solution of 6x= 15
Answer:
2.5
Step-by-step explanation:
When a variable is next to a number (coefficient) it means you need to multiply. In this equation 6x are next to eachother.
Because we don't know what x is, we have to work backwards.
The opposite of multiplying is dividing, so here we can do...
15/6 and that equals 2.5
To check you replace x with 2.5 like so,
6(2.5)= 15 and it is true!
Hope this helps and have a great day!

f(x)=22x+14, find f(5)
Answer:
f(5) = 124
Step-by-step explanation:
Step 1: Define
f(x) = 22x + 14
f(5) = x = 5
Step 2: Substitute and evaluate
f(5) = 22(5) + 14
f(5) = 110 + 14
f(5) = 124

Answer:
C) 6
Step-by-step explanation:
I converted the equation into slope-intercept form and then identified the y-intercept.
[tex]4x+2y=12\\\\4x-4x+2y=12-4x\\\\2y=12-4x\\\\\frac{2y=12-4x}{2}\\\\ y=6-2x\\\\y=-2x+6\\\\y=-2x+\boxed{6}[/tex]
C should be the correct answer.
Hope this helps.
Answer: 6
Step-by-step explanation: The y-intercept is a point where a line
crosses the y-axis and all y-intercepts have an x-coordinate of zero.
So to find the y-intercept of this line, we can plug a 0 in for x.
So we have 4(0) + 2y = 12.
So 2y = 12 which means that y = 6.
So the y-intercept of this line is 6.

Ori needed at least $1.47 in postage to mail an envelope to his cousin overseas. If x represents the number of $0.44 cent stamps he has and y represents the number of $0.10 cent stamps he has, the inequality representing the number of stamps he can use to mail the envelope is 0.44x+0.10y≥1.47. If Ori uses all 3 of the $0.44 cent stamps he has, what is the minimum number of $0.10 stamps he needs to use?
The minimum number of $0.10 stamps he needs to use is 1 stamp.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
let x represents the number of $0.44 cent stamps
and, y represents the number of $0.10 cent stamps
Ori uses all 3 of the $0.44 cent
=0.44x3
= 1.32
Then, 1.47-1.32= 0.15
We have at least 2 dimes for the equation
=0.44(3)+0.10(2)≥1.47
= 1.32+0.20≥1.47
= 1.52≥1.47
Then, number of $0.10 stamps he needs to use
= 0.15/ 0.10
= 1.5
= 2 or 1 stamps

Step-by-step explanation:
A group of 6 hikers are preparing for a one week trip. All of the group's supplies will be carried by the hikers in
backpacks. The leader decides that each hiker will carry a backpack that is the same fraction of weight to all the other
hikers' weights. This means that the heaviest hiker would carry the heaviest load. The table below shows the weight of
each hiker and the weight of the backpack
Complete the table. Find the missing, amounts of weighit by applying the same value of the ratio as the first two rows.
Backpack Weight
Hiker's Weight
152 15.402
Total Weight (lb.)
14 1b, 802
107 lb, 10 oz
10 lb. 4 02
129 lb. 15 02
68 10.40
8 lb. 12 oz
10 lb
Answer:
Step-by-step explanation:
1 oz = 0.0625 lb
Ratio of the hiker an backpack in the first row = 152.25 lb : 14.5 lb
= 21 : 2
Hiker's weight Backpack weight Total weight (in lb)
1). 152 lb 4 oz 14 lb 8 oz (152+14) lb (4+8) oz = 164lb 12oz
= 16.75 lb
2). 107 lb 10 oz 10 lb 4 oz (107+10) lb (10+4) oz = 117 lb 14 oz
= 117.875 lb
3). 129 lb 15 oz [tex]\frac{129.9375}{x}=\frac{21}{2}[/tex] (129+12) lb (15+6)oz = 141 lb 21 oz

If two rectangles are congruent, it means they are the exact same shape and size.
I have uploaded an image with this answer. In the image, you can see two rectangles with the same perimeter. However, they are not congruent because they are not of the same size (even though they are of the same shape - a rectangle).
Hence, two rectangles may not be congruent if they have the same perimeter.

The value of x and y from the equation is 1/6 and 5/6 respectively

y = 5/6
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be A
11x - 7y = -4 be equation (1)
Let the second equation be B
-14x - 2y = -4 be equation (2)
On simplifying , we get
Multiply equation (2) by 7 , we get
-98x - 14y = -28 be equation (3)
Multiply equation (1) by 2 , we get
22x - 14y = -8 be equation (4)
Subtract equation (4) from equation (3) , we get
-120x = -20
Divide by 120 on both sides , we get
x = 1/6
Now , substituting the value of x in equation (1) , we get
11x - 7y = -4
11 ( 1/6 ) - 7y = -4
Adding 7y on both sides , we get
7y - 4 = 11/6
Adding 4 on both sides , we get
7y = 11/6 + 4
7y = 35/6
Multiply by 7 on both sides , we get
y = 5/6
Hence , the value of x is 1/6 and value of y is 5/6
