Answer:

x= 1 , y=4

Step-by-step explanation:

x-y= -3 => Equation 1

x+5y= 21 => Equation 2

Substitution Method:

Substitute Equation 1=>

x=y-3 <= Equation 3

Put x=y-3 in Equation 2:

x+5y=21

( y-3)+5y=21

y-3+5y=21

6y-3=21

6y=21+3

6y=24

y=24÷6

y=4

Put y=4 in Equation 1:

x-y= -3

x-4=-3

x=4-3

x=1

Hope this helps :)

Answer:

x = 1

y = 4

Step-by-step explanation:

x - y = -3   then x = y - 3

x + 5y = 21

substitute for x:

y - 3 + 5y = 21

reduce:

6y = 24

y = 4

x = 4 - 3 = 1

check:

1 - 4 = -3

-3 = -3

and

1 + 5(4) = 21

21 = 21

Please help ASAP Gavin works as a salesperson at an electronics store and sells phones and phone accessories. Gavin earns a $12 commission for every phone he sells and a $3.50 commission for every accessory he sells. On a given day, Gavin made a total of $135 in commission and sold 12 more accessories than phones. Determine the number of phones sold and the number of accessories sold.

There were
____phones sold and
____ accessories sold.

Answers

Answer:

6 phones and 18 accessories

Step-by-step explanation:

12P + 3.50A = 135

A = 12 + P

12P + 3.50(12 + P) = 135,

12P + 42 +3.50P = 135

15.50P = 93

P = 6 phones

A = 12 + 6 = 18 accessories

There is nothing in the problem statement that suggests this is a right triangle. Without knowing at least one angle, we cannot solve for a numerical value for the perimeter. The problem title suggests we're to leave the result in polynomial form.

Find the values of x and y. y=? x=? PLEASE HELP

Answers

Answer:

x=15.714

y=5.715

Step-by-step explanation:

Answer:

x=10, y=20

Step-by-step explanation:

okay so to find x, or the way I did it, we just have to look at the top, we know one line is 180 degrees, and we see three angles, 7x,90, and 20

so 90+20+7x=180

and:110+7x=180

therefore: 7x=70

and finally: x=10

To find y also isn't had if we just look at the blue and green lines we see they are intersecting and opposite angles in intersecting lines are congruent meaning they are the same. So we now know that:

5x+2y=90

and we know x=10

so 5x=50

meaning that: 50+2y=90

therefore: 2y=40

and in conclusion y=20

Please help!!!!!

Answers

Answer:

96

Step-by-step explanation:

100%-60%=40%

40% of x = 64 students (X=Total no. of students)

(40/100)*x=64

x=64*(100/40)

x=160

Missing no. of students=160-64=96

Answer:

96 students

Pls mark me brainliest!

Step-by-step explanation:

If an unknown amount of students is 60% of the students, the 64 of the students must be 40% of the students because 40+60 = 100.

You want to find what 1% equals, so we will divide 64 by 40 because 40% divided by 40 = 1% and whatever you do to one side you do to the other.

64/40 = 1.6

Assuming that the ? number of students that equals 60% will be a whole number, lets go with 1.6.

If 1.6 = 1%, and we want 60%, then multiply both sides by 60, because 1*60 = 60.

1.6*60 = 96

96 students
