Answers
Answer:
The solution is (0, 4)
Step-by-step explanation:
Please pay attention to the first two equations and drop the last two:
12x−5y=−20 y=x+4 x=x=x, equals y=y=y should ideally be:
12x−5y=−20
y=x+4
Let's find x. Substitute x + 4 for y in the first equation, obtaining:
12x - 5(x + 4) = -20
Carrying out the indicated multiplication, we get:
12x - 5x - 20 = -20, or 7x = 0
If x = 0 then y must be 0 + 4, or 4.
The solution is (0, 4)
Answer:x=0 y=4

El perímetro de una circunferencia es de 40π cm, y tiene un ángulo de 130°. Calcula el área del sector de dicha circunferencia.
Answers
Answer:
Area of sector = 144.4π cm²
Step-by-step explanation:
Given:
Perimeter of circle = 40π cm
Given angle = 130°
Find:
Area of sector
Computation:
Perimeter of circle = 2πr
⇒ 40π = 2πr
⇒ 40 = 2r
⇒ Radius r = 40 / 2
Radius r = 20 cm
Area of sector = [θ/360][π][r]²
⇒ Area of sector = [130/360][π][20]²
⇒ Area of sector = [0.361][π][400]
Area of sector = 144.4π cm²

Answers
Answer:
[tex]2\dfrac{1}{3}\ \text{cups}[/tex]
Step-by-step explanation:
Amount of chopped onions required = [tex]3\dfrac{2}{3}\ \text{cups}[/tex]
Amount of onions Katrina has already chopped = [tex]1\dfrac{1}{3}\ \text{cups}[/tex]
Amount of onions that are required to be chopped is given by
[tex]3\dfrac{2}{3}-1\dfrac{1}{3}\\ =\dfrac{11}{3}-\dfrac{4}{3}\\ =\dfrac{7}{3}\\ =2\dfrac{1}{3}\ \text{cups}[/tex]
Hence, the amount of onions that are required to be chopped is [tex]2\dfrac{1}{3}\ \text{cups}[/tex].

Isaac paid $81 for a new surfboard. The amount paid was 60% of his total savings. How much money did he have in his savings before buying the surfboard?
Answers
Answer:
$135
Step-by-step explanation:
Given data
Amount paid for new surfboard= $81
Percentage of the savings paid= 60%
Let the amount of the savings be x
Hence
60% of x= 81
60/100*x= 81
0.6x=81
x= 81/0.6
x=$135
Hence his savings was $135

Third:
910
___
100
You put the fractions like this and cross out the two zeros to get this:
91
__
10
Lastly you divide 91 and 10 which gives you 9.1 and if you don'y want a decimal then round it to the nearest whole number which gives you 9.
