Answer:
give me the brainliest
Step-by-step explanation:
Let x is the ones digit
Let y is the tens digit
Given that:
You use a total of 15 base ten blocks to show this number:
<=> x + y = 15 (1)
One of the digits is 6, so substitute into (1) we have another digit equals to: 9
Because the number of ones block is greater than the number of ten blocks
<=> y > x
<=> y = 9 and x= 6
So that number is: 69.

If the price of a yo-yo in a shop increased by 20% and is now $3.60, what was the original price?
Answer:
$3.00
Step-by-step explanation:
$3.00 x .2 = 0.60. added to original
The original price of the yo-yo in a shop is $3.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
It is given that the price of a yo-yo in a shop increased by 20% and is now $3.60.
The original price will be calculated as let the original price is x dollars. Then from the question, the expression will be formed as below:-
1.20x = 3.60
x = 3.60 / 1.20
Divide 3.60 by 1.20 to get the value of x.
x = $3
It means that the 20 percent is equal to the amount of $0.6.
Therefore, the original price of the yo-yo in a shop is $3.

Step-by-step explanation:
just did the math
Correct Answer is 0.13
Probability:
The probability formula is the number of favourable outcomes to the total number of all the possible outcomes.
The probability of an Event = (Number of favourable outcomes) / (Total number of possible outcomes)
P(A) = n(E) / n(S)
Here, (Given)
n(E) = The participant prefers football and the event is foam finger = 39
n(S) = Total number of outcomes = 300
P(A) = probability the participant prefers football and the event foam finger.
P(A) = 39 / 300

Answer:
Green line
Step-by-step explanation:
This is the only line that has coordinates (1,2) and the slope is positive.
Answer: You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.

Equation of a line that goes through point (4,2) and perpendicular to -x+y=1
Answer:
y= -x + 6
Step-by-step explanation:
-x + y =1 ---> y = x+1
the line perpendicular to this line should have negative inverse slope
the slope is 1 so the negative inverse of 1 is -1
set up
y = -x +b
since it goes through (4,2)
then we have
2 = -4 +b
b=6
so the linear equation is y = -x+6

Answer:b) If there are 20 squares there will be 25 triangles.
c) There are 20 girls
Step-by-step explanation:
b) The ratio here is 4(squares):5(triangles), so if there are 20 squares you have to divide that by the original number of squares, 4. Once you get that, you multiply it by the number of triangles, 5. The work should look something like this:
20/4 = 5
5 x 5 = 25
c) For this one you have to add the total number of students within the ratio. Since there 5 girls and 2 boys, that is 7 people in total. Since you’re trying to reach a total of 28, you divide 28 by 7, which will give you 4. Now, you multiply 4 by the number of just girls, (5), which gives you a total of 20.

A shopkeep offers a discount of 20% on all the articles at his shop and still makes a profit of 12%. What is the CP of an article whose MP is Rs280?
CORRECT answer will be mark as brainliest.
Help me!
Given info:-
A shop keeper offers a discount of 20% on all the articles at his shop and all makes a profit of 12%.
What is the CP of an article whose MP is Rs. 280 ?
Explanation:-
Given that
The Marked Price of an article (M) = Rs. 280
Discount on it = 20%
Discount (D) = MD/100
⇛ Discount = (280×20)/100
⇛ Discount = 28×2
⇛ Discount =56
Selling Price = Marked Price - Discount
⇛ Selling Price = 280-56
⇛ Selling Price = Rs. 224
Selling Price of the article = 224
Profit on it = 12%
We know that
Cost Price = (100×SP)/(100+g)
⇛ CP = (100×224)/(100+12)
⇛ CP = 22400/112
⇛ CP = 200
Therefore, The CP = Rs. 200
The Cost Price of the article = Rs. 200.
Formula:-
Discount (D) = MD/100M = Marked Price
Selling Price = Marked Price - Discount Cost Price = (100×SP)/(100+g)SP = Selling Price
g = gain or profit

Write an equation for a line parallel to 4x – 2y = 4 that passes through the point (3,22)
Answer:
y = 2x + 16
Step-by-step explanation:
4x - 2y = 4
-2y = -4x + 4
y = -4/-2x + 4/-2
y = 2x - 2
Slope: 2
Point: (3,22)
y-intercept: 22 - (2)(3) = 22 - 6 = 16
Answer:
y=2x+16 or 2x-y=-16
Step-by-step explanation:
Hi there!
We are given the equation 4x-2y=4, and we want to write an equation for the line parallel to it, that also passes through (3, 22)
First, let's find the slope of the line, as parallel lines have the same slope.
In order to find the slope, we can convert the equation from standard form (ax+by=c) into slope-intercept form (y=mx+b).
Start by subtracting 4x from both sides:
-2y=-4x+4
Divide both sides by -2
y=2x-2
2 is in the place where x is, so the slope of the line is 2
It's also the slope of the line parallel to it.
Writing the equation in slope-intercept form, this is the equation so far:
y=2x+b
Now let's find b
Since the equation passes through the point (3,22), we can use it to help solve for b
Substitute 22 as y and 3 as x:
22=2(3)+b
Multiply
22=6+b
Subtract 6 from both sides
16=b
Substitute 16 as b in the equation.
y=2x+16
We can stop right here, but we can also re-convert it into standard form
To do that, subtract 2x from both sides:
-2x+y=16
There's a rule that the coefficient in front of x CANNOT be negative; in order to change the sign, multiply both sides of the equation by -1
2x-y=-16
Hope this helps!
