5.3x + y = 28.5
4.2x + 3.1y = 27.2
find x and y
Answer:
x = 5, y = 2
Step-by-step explanation:
First, isolate y in the top equation.
[tex]y = -5.3x+28.5[/tex]
Next, substitute y in the bottom equation.
[tex]4.2x + 3.1(-5.3x + 28.5) = 27.2[/tex]
[tex]5.3x + y = 28.5[/tex]
Simplify.
[tex]4.2x + -16.43x + 88.35 = 27.2[/tex]
Combine like terms.
[tex]-12.23x + 88.35 = 27.2[/tex]
Isolate x on one side.
[tex]-12.23x = -61.15[/tex]
Isolate x.
[tex]x = 5[/tex]
Substitute x into [tex]5.3x + y = 28.5[/tex]
[tex]5.3(5) + y = 28.5[/tex]
Simplify.
[tex]26.5 + y = 28.5[/tex]
Isolate y.
[tex]y = 2[/tex]
[tex]x = 5 \\y = 2[/tex]

(3^0+2^0)(5^0)
=(3^0+2^0)(5^0)
=(3^0)(5^0)+(2^0)(5^0)
= 1 + 1
= 2
Answer:
2
Step-by-step explanation:
The answer comes from what is inside the brackets.
anything ^ 0 = 1
So 3^0 + 2^0 = 1 + 1 = 2
5^0 = 1
2 *1 = 2
A video posted to the internet had 3,200 views in its first week
(a ) The video got 4, 640 views in its second week. What was the percent increase in the views from the first week?
Answer:
45%
Step-by-step explanation:
The computation of the percentage increase from the first week is shown below:
Given that
In the first week there is 3,200 views
And, in the second week, there is 4,640 views
So, the percentage increase is
= (Second week views - first week views) ÷ (first week views)
= (4,640 - 3,200) ÷ (3,200)
= 45%

A running track has two straight sides with length 140 m and two semicircle ends with radius 70 m. It takes Kat 40 seconds to jog 160 m. How long would it take her to jog around the track 51 times? Give your answer in hours and minutes, to the nearest minute.
It would take her 4590 seconds to jog round the track 51 times
Speed is the ratio of the total distance travelled to total time taken. It is given by:
Speed = distance / time
Kat uses 40 seconds to jog 160 m, hence:
Speed = 160 m / 40 s = 4 m/s
The track length = 140 m + 2 * (π * 70) = 360 m
Time taken to jog round the track (t) is:
4 m/s = 360 m / t
t = 90 s
To jog round the track 51 times, time taken = 51 * 90 s = 4590 seconds
It would take her 4590 seconds to jog round the track 51 times

Jackson and his sister ran a hose from a bucket into their swimming pool. The hose sprays 1/3 of a gallon from the bucket every second. The bucket started with 32 gallons of water. How long will it take to empty the bucket?
Answer:
96 seconds
Step-by-step explanation:
In order to find how long it will take to empty the bucket, you must multiply the number of gallons by the reciprocal of the fraction.
1. Reciprocal of [tex]\frac{1}{3}[/tex] is [tex]\frac{3}{1}[/tex] which is 3
2. multiply 32 by 3 to get your answer, 96.

what is the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1)?
Answer: The other point is (17, -6).
Step-by-step explanation:
Midpoint (x,y) of the line segment joining (a,b) and (c,d) is given by :-
[tex](x,y) =(\dfrac{a+c}{2}, \dfrac{b+d}{2})[/tex]
Here, we need to find the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1).
Let other point be (a,b), then
[tex](7,1)=(\dfrac{-3+a}{2},\dfrac{8+b}{2})\\\\\Rightarrow\ \dfrac{-3+a}{2}=7\ \text{ and }\dfrac{8+b}{2}=1\\\\\Rightarrow\ -3+a = 7\times2 \text{ and } 8+b=1\times2\\\\\Rightarrow\ -3+a=14\text{ and }8+b=2\\\\\Rightarrow\ a=14+3, \ \ \ b= 2-8\\\\\Rightarrow\ a=17, b= -6[/tex]
hence, the other point is (17, -6).

One side of a rectangle is 3 inches shorter than the other side, and the perimeter is 54 inches. What are the dimensions of the rectangle?
Which of the following equations could be used to solve the problem?
A. 2 x + 2( x - 3) = 54
B. 2 x - 3 = 54
C. 2 x + 2 x - 3 = 54
Answer:
A
Step-by-step explanation:
Let the two sides of the rectangle be x and y.
Then the perimeter will be:
[tex]2x+2y=P[/tex]
Since the perimeter is 54:
[tex]2x+2y=54[/tex]
We know that one side of the rectangle is 3 inches shorter than the other.
Let y be the shorter side. It is 3 less than x.
Therefore:
[tex]y=x-3[/tex]
Then by substitution, we acquire:
[tex]2x+2(x-3)=54[/tex]
The answer is A.
