Solve The System Of Equations

Answers

Answer 1

Answer:

x= -8

y=7

Step-by-step explanation:

make it so the x's cancel out

to do this multiply the bottom equation by 2

2x+3y=5

2x+4y=12

subtract to cancel out the x

-y=-7

y=7

now substitute y into one of the equations(I'm going to do x+2y=6)

x+2(7)=6

x+14=6

x=-8

Answer 2
Multiply the bottom equation by -2

2x + 3y = 5
-2x + -4y = -12
-y = -7
y = 7

x + 2(7) = 6
x + 14 = 6
x = 6 - 14
x = -8

x = -8, y = 7
(-8,7)

15) 2/5 or 3/10
16) 1/5 or 1/4
17) 3/4 or 18/24​

Answers

2/5 because it’s the same as 4/10
1/4 because it’s 5/20 and 1/5 is 4/20
they are both the same because 3/4 is the same as 18/24
hope that helps!

Answer:

15) 2/5

16) 1/4

17) Same

Step-by-step explanation:

15) Multiply 2/5 by 2 on both the numerator and denominator which is 4/10 now you can clearly tell that 2/5 is greater.

16) Multiply 1/5 by 4 on both the numerator and denominator and multiply 5 on both the numerator and denominator in 1/4 for 1/4 you will get 5/20 and for 1/5 you will get 4/20 and you can tell that 5/20 is greater which is 1/4.

17) Multiply 3/4 by 6 on both the numerator and denominator you will get 18/24 so 18/24 and 3/4 are equivalent.

Slope!! Need help thank you!!

Step-by-step explanation:

slope is rise over run the rise is 1 and the run is 4

I’m not the best at slopes but I think it’s d.

Reasoning : well it’s takes for time got it to get to one full number so therefore it’s going up 1/4 for each one space.

Well now is it a positive or a negative the line reading left to right going up means it’s a positive this I know for sure.

Again I’m not the best at these so take my answer with a gain of slat. I’m so sorry If I’m wrong but please put the right answer if I am for others that need this question I don’t mind being corrected I encourage you to do it.

But if I am right please give me brainiest I need it to go to the next level XD

A farmer has chickens and pigs on a farm. The farmer counted 22 heads and 56 feet on all the animals. How many chickens and pigs does the farmer have?

Answers

Answer: 16 chickens, 6 Pigs

Step-by-step explanation:

Given

Toal heads=22

Total feet=56

Suppose there are x chickens and y pigs

each animal possess a single head

[tex]\therefore\ x+y=22\quad \ldots(i)[/tex]

Chicken has 2 legs and pig has 4 legs

So, [tex]2x+4y=56\quad \ldots(ii)[/tex]

Solving (i) and (ii) we get

x=16 and y=6

So, farmer has 16 chickens and 6 pigs

Find and simplify an expression for the area of three rows of m squares with side lengths of m centimeters. Please help

Answers

The expression for the area of three rows of m squares with side lengths of m centimeters is [tex]3m^3[/tex] square centimeters.

To find the area of three rows of m squares with side lengths of m centimeters, determine the total number of squares.

Each row consists of m squares, and there are three rows in total. Therefore, the total number of squares is 3m.

The area of each square is given by the formula

[tex]A = s^2[/tex],

where s is the length of the side.

Multiply the area of one square by the total number of squares:

Area = (Area of one square)  (Total number of squares)

Area = [tex]m^2[/tex] * 3m

Area = [tex]3m^3[/tex]

Therefore, the expression for the area is [tex]3m^3[/tex] square centimeters.

The simplified expression for the area of three rows of m squares with side lengths of m centimeters is 3 * m^3 square centimeters.

To find the area of three rows of m squares with side lengths of m centimeters, we need to determine the total area covered by the squares.

Each row consists of m squares, and each square has a side length of m centimeters. Therefore, the length of each row is m * m = m^2 centimeters.

Since there are three rows, the total length covered by the rows is 3 * m^2 centimeters.

To find the area, we need to multiply the total length by the width, which is also m centimeters. Thus, the area of the three rows of squares is:

Area = Length * Width

Area = (3 * m^2) * m

Area = 3 * m^3 square centimeters

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 17)(0,17) and (2, 1700)(2,1700).

Answers

Answer:

y = 17 · 10ˣ

Step-by-step explanation:

We can already get some idea of what this function might be by looking at what happens to the y value as we increase the x value of the function. We start at x = 0 with y = 17, and increasing x by 2 to x = 2 makes y = 1700. Notice that by increasing x by 2, we've added two zeroes to the end of 17. The only number which has this property in the decimal system is 10, so that must be our base, and our initial value must be 17. So our function is

[tex]y=17\cdot10^x[/tex]

We can verify this by running each of those points through the equation:

[tex]17=17\cdot10^0=17\cdot1=17\\1700=17\cdot10^2=17\cdot100=1700[/tex]

Answers

Given :

A building casts a shadow 46 feet long.

At the same time, a 36 foot tall flagpole costs a shadow of 9.2 feet long.

To Find :

The height of the building.

Solution :

Since, all readings are taken in same time.

Ratio of height and shadow remains for all objects.

Let, height of building is H.

So,

[tex]\dfrac{H}{46}=\dfrac{36}{9.2}\\\\H = \dfrac{36}{9.2}\times 46\\\\H = 180\ feet[/tex]

Therefore, height of the building is 180 feet.

I keep getting this question wrong

Answers

Answer: see below

Step-by-step explanation:

Set up two equations, one for each scenario

88w + 21b = 5840

84w + 82b = 9044

Use one equation and isolate one of the variables. We'll isolate w in the first equation.

88w + 21b = 5840

88w = 5840 - 21b

w = (5840 - 21b)/88

Then substitute that into the second equation.

84w + 82b = 9044

42w + 41b = 4522 (simplified)

42((5840 - 21b)/88) + 41b = 4522

21((5840 - 21b)/44) + 41b = 4522 (simplified)

(122640 - 441b)/44 + 1804b/44 = 4522

(122640 - 441b + 1804b)/44 = 4522

122640 + 1363b = 198968

1363b = 76328

b = 56

Now that we know belts are $56, we can substitute that back into any equation and solve for w.

w = (5840 - 21b)/88

w = (5840 - 21(56))/88

w = (5840 - 1176)/88

w = 4664/88

w = 53
