Math riddle! Correct answer gets brainliest!
Answer with what x and y are equal to.
Answers
Answer:
[tex]\displaystyle [9, 4\frac{1}{2}][/tex]
Step-by-step explanation:
I figure these exercises out by numeric association. I see a 3, so I know right away that there might be a 9 somewhere. So, you start by plugging 3 in for [tex]\displaystyle x,[/tex] THEN plug [tex]\displaystyle 1\frac{1}{2}[/tex] in for [tex]\displaystyle y[/tex] sinse there are twise the quantity of [tex]\displaystyle y[/tex] than there are of [tex]\displaystyle x.[/tex] Now, doing so will give you [tex]\displaystyle 24 ≠ 18.[/tex] This tells you to try another pattern, so go with plugging [tex]\displaystyle 4\frac{1}{2}[/tex] in for [tex]\displaystyle y[/tex] and [tex]\displaystyle 9[/tex] in for [tex]\displaystyle x[/tex]. Doing so gives you what you are looking -- [tex]\displaystyle 36 = 36.[/tex] Therefore, the association wourked perfectly. ☑
I am joyous to assist you at any time.
That locked sign defines that both sides are equal.
The equations are
2x=4y=>x=2y--(1)3x+9=2x+4y=>x+9=4y=>x=4y-9--(2)From (1) and (2)
[tex]\\ \rm\Rrightarrow 4y-9=2y[/tex]
[tex]\\ \rm\Rrightarrow 2y=9[/tex]
[tex]\\ \rm\Rrightarrow y=9/2=4.5[/tex]
Put in eq(1)
x=2(4.5)=9Hence
(x,y)=(9,4.5)Related Questions

Pleaseeeeee help! I don’t understand and I just wanna go to sleep but this is due in 35 minutes
Answers
Answer:
69
Step-by-step explanation:
it is 69 becuase 4x-7+11x-8 equals 69
We have: 2.(4x - 7)° + 2(11x - 8)° = 360°
So: 8x - 14 + 22x - 16 = 360°
<=> 30x - 30 = 360°
<=> 30(x - 1) = 360°
<=> x - 1 = 12
<=> x = 13°
We know: ∠G = ∠F = (11x - 8)° = ( 11.13-8)° = 135°
The answer: ∠G = 135°
Ok done. Thank to me :>

Dan made 85% of his free throws. If he took 45 shots how many did he make?
Answers
Answer:
38
Step-by-step explanation:
85%=.85
So 45 × .85 = 38.25
38 shots he made.
Hope this helps
Work Shown:
85% = 85/100 = 0.85
85% of 45 = 0.85*45 = 38.25
Rounding to the nearest whole number, we get the result 38
As a check, 38/45 = 0.8444 approximately which converts to 84.44% and that's fairly close to 85%. If we tried 39, then 39/45 = 0.8667 = 86.67% which is a bit too high.

Ryan wants to measure the length of a bed cover which of the following would be the most appropriate unit to use?
A) kilogram
B) kilometer
C) meter
D) mile
Answers
The answer is meter since grams is used to measure weight and kilometer and mile are used to measure something larger.
Answer:
C. Meter
Step-by-step explanation:
1. Kilograms measure weight, not distance/length, so it wouldn't make sense to use them to measure a bed.
2. Kilometers are used to measure very long distances, as are miles, so it wouldn't make sense to use them on something small like a bedframe.
That means the only option left is C. Meter.
Hope this helps.

If Mrs. Hill takes out a mortgage for $80,000 with a 4% interest rate, what will her interest be after 20 years? Help ASAP
Answers
Answer:
$6400
Step-by-step explanation:
If Mrs. Hill takes out a mortgage for $80,000 with a 4% interest rate, what will her interest be after 20 years?
First you want to find how much she will get each year.
Turn 4% into a decimal.
Which you have to move the decimal point over to spaces to the left.
4. ----- .4 ----- .04
Now that you have done that you need to multiply,
$80000 × .04
which is $3200.
Now you know she gets $3200 a year.
Now multiply $3200 by 20.
$3200 × 20
which is $6400.
She will get $6400 interest.
