Step-by-step explanation:
im still in 6th grade
Answer:
55 dimes and 70 quarters
Step-by-step explanation:
Using a simple strategy of guess and check we know that the quarters will always be 15 more than dimes. From this we know it has to be around the 50s as 40s would bring us numbers too low and 60s too high. 55 happens to be answer for dimes as that brings in $5.50. 23-5.5=17.5 multiply that by 4 as each quarter is only valued at $0.25 you get the answer 70 which just so happens to meet the requirements of being 15 more than 55.

Solve the system of equations
-3x+2y=-6
5x-2y=18
Please help me
Answers
Answer:
the answer is (x,y) = (6,6)
Step-by-step explanation:
1) first solve the equation for 2y
you should've gotten:
2y = -6 + 3x
5x - 2y = 18
2) substitute the value of 2y into the equation
5x - 2y = 18
so, 5x -(-6 + 3x) = 18
3) now solve 5x -(-6 + 3x) = 18
4) from that solving that equation, u should've gotten x = 6
5) now plug in 6 for x in the other equation, solve for y
( • stands for multiplication if u didn't know, we use this in higher levels of math so multiplication symbols and x variables aren't confused)
5 • 6 - 2y = 18
6) after solving for y in the previous equation, u should've gotten y = 6
7) now we know that x = 6 and y = 6, however it is always important to check if ur answer is correct by plugging in the x value y values u ended up with into the original system of equations.
checking ur work would look something like this:
2(6) = -6 + 3(6)
5(6) - 2(6) = 18

Answer:408=screen time
Step-by-step explanation:240+168 70%=168
make sure to like with the heart
Answer:
I believe 408 minutes a day
Step-by-step explanation:
So, I have my own method which is to divide the whole (in this case, 240) by 10 and multiply by whatever percent you have to multiply by and you add it to the whole.
ex.
240/10 = 24
24x7=168
240+168= 408
to do with 100s like 73% then divide the whole by 100 :)

What is 9/2 × 20/3 × 9/4?
Answers
Answer:
67.5
Step-by-step explanation:
4.5 times 6.66 times 2.25 will be 67.5
9/2 * 20/3 * 9/4
= (9 * 20 * 9)/(2 * 3 * 4)
= (1620)/(24)
= 1620/24
= 67.5
So, in conclusion, 9/2 * 20/3 * 9/4 is equal to 67.50 or 1620/24.

There are 15 boys in Ella's class and 16 boys in Minh's class.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, The ratio of boys to girls in Ella's class is 3 to 4. The ratio of boys to girls in Minh's class is 4 to 5.
Each class has a total of 20 girls and assuming each class has a total of x students.
∴ 4x/7 = 20.
4x = 140.
x = 35.
No. of boys = 15.
5x/9 = 20.
5x = 180.
x = 36.
No. of boys = 16.

identify the diameter of Q given that a= 169 pie in2
Answers
Answer:
the diameter will be D=26 in.
Step-by-step explanation:
The area of a circle is given by:
[tex]A=\pi R^{2}[/tex] (1)
Where:
A is the areaR is the radius of the circleNow, we know that A = 169 π in²
So, we just need to use equation 1 to find R.
[tex]169\pi = \pi R^{2}[/tex]
[tex]R=\sqrt{169}[/tex]
[tex]R=13 \: in[/tex]
Therefore, the diameter will be D=2*R=26 in.
I hope it helps you!
The diameter of the circle is 26 inches
The area of the circle is given as:
[tex]A = 169\pi[/tex]
The area of a circle is calculated as:
[tex]A = \pi r^2[/tex]
By comparison, we have:
[tex]\pi r^2 = 169\pi[/tex]
Divide both sides of the equation by pi
[tex]r^2 = 169[/tex]
Take the positive square roots of both sides
[tex]r = 13[/tex]
Multiply by 2, to calculate the diameter
[tex]d =2 * 13[/tex]
[tex]d = 26[/tex]
Hence, the diameter of the circle is 26 inches
