Answer:

x = 5, and y = 8

Step-by-step explanation:

You can solve this system by solving either of the equations for either x or y, and substituting that into the other.

Since the first equation is already defined for y, let's substitute that into the second equation:

4x - 5y = -20

4x - 5(3x - 7) = -20

4x - 15x + 35 = -20

4x - 15x = -20 - 35

-11x = -55

x = 5

We can then plug that into either of the original equations to find y:

y = 3x - 7

y = 3 * 5 - 7

y = 15 - 7

y = 8

We can also verify our answer by plugging one of the values into either of the original equations and seeing what we get:

4x - 5y = -20

4x - 5 * 8 = -20

4x - 40 = -20

4x = 20

x = 5

So we know the answer is correct.  x is equal to five, and y is equal to eight.

Answer:

eJeriche is correct, the answer is 4m - 3w + 4n, John didn't collect the like terms correctly

Step-by-step explanation:

Answer: 4m - 3w + 4n - this is the right decision.

Step-by-step explanation:

m - 5w + 3m + 4n + 2w = m + 3m - 5w + 2w + 4n = 4m - 3w + 4n

Jericho wrote correctly, and John - not.

John put together various variables n and m, which is not allowed.

Answer: 136 ounces

Step-by-step explanation:

Given: The ratio of cranberries and raspberries is 8:9 .

Let quantity of cranberries= 8x , quantity of raspberries = 9x

If quantity of cranberries = 64 ounces

[tex]\Rightarrow\ 8x=64\\\\\Rightarrow\ x=\dfrac{64}{8}\\\\\Rightarrow\ x=8[/tex]

Quantity of raspberries = 9(8) = 72 ounces

Total quantity = 64 ounces  +  72 ounces =  136 ounces

Hence, the total weight of berries purchased=  136 ounces

Step-by-step explanation:

angles opposite each other are equal as opposed to add up to 180

so

5x = 100

x = 20

Answer:

x = 12

Step-by-step explanation:

[tex]90 + 3x + 16 + 2x + 14 = 180 [/tex]

[tex]5x + 120 = 180[/tex]

[tex]5x = 180 - 120[/tex]

[tex]5x = 60[/tex]

[tex]x = \frac{60}{5} = 12[/tex]

Answer:

x = 12°

Step-by-step explanation:

[tex](3x + 16) + 90 + (2x + 14) = 180 \\ 3x + 2x = 180 - 16 - 90 - 14 \\ 5x = 60 \\ x = \frac{60}{5} \\ x = 12[/tex]

The value of Cosα  from the triangle is 21/29

ABC is a right angled triangle

We have to find the Cosα

We know that cosine function is a ratio of adjacent side and hypotenuse

Let us find the value of  Cosα

The adjacent side of angle α is 21

The hypotenuse is 29 in the triangle

Cosα = Adjacent side/hypotenuse

Plug in the values of adjacent side and hypotenuse

Twenty one divided by twenty nine

=21/29

Hence, the value of Cosα  from the triangle is 21/29

Answer:

Option B: 25 inches, 60 inches and 65 inches is the correct answer.

Step-by-step explanation:

We will use Pythagorean theorem to find out the dimensions that Adam should use.

A. 50 in, 110 in and 130 in

Using Pythagorean theorem;

[tex]a^2+b^2=c^2 \\(50)^2 + (110)^2 = (130)^2\\2500 + 12100 = 16900\\14600\neq 16900[/tex]

These dimensions will not form a right triangle.

B. 25 in, 60 in, and 65 in

[tex](25)^2 + (60)^2=(65)^2\\625+3600= 4225\\4225=4225[/tex]

These dimensions of the frame will form a right triangle.

C. 40 in., 44 in., 58 in.

[tex](40)^2+(44)^2=(58)^2\\1600+1936=3364\\3536\neq 3364[/tex]

These dimensions will not form a right angled triangle.

D. 130 in., 50 in, 60 in

The larger dimension represents the hypotenuse in right angled triangle.

[tex](50)^2+(60)^2=(130)^2\\2500+3600=16900\\6100\neq 16900[/tex]

These dimensions will not form a right angled triangle.

Option B: 25 inches, 60 inches and 65 inches is the correct answer.
