What Is The Value Of X And Y?

Answers

Answer 1

Answer:

[tex] x=\boxed{2} [/tex]

[tex] y=\boxed{4}[/tex]

Step-by-step explanation:

[tex] \begin{cases} y= 6x-8... (1)\\\\y=-3x+10...(2)\end{cases} [/tex]

From equations (1) & (2), we find:

6x - 8 = - 3x +10

[tex] \therefore 6x+3x = 8+10[/tex]

[tex] \therefore 9x = 18[/tex]

[tex] \therefore x =\frac{18}{9}[/tex]

[tex] \therefore x = 2[/tex]

Plug x = 2 in equation (1)

y = 6(2)-8 = 12-8 =4

So,

[tex] x=\boxed{2} [/tex]

[tex] y=\boxed{4}[/tex]

Answer:

(4, 5)

Step-by-step explanation:

5x + y = 25

-3x + 2y = -2

5x + y = 25

y = 25 - 5x

-3x + 2 * (25 - 5x) = -2

-3x + 50 - 10x = -2

-13x = -52

x = 4

5 * 4 + y = 25

20 + y = 25

y = 5

x=4
y=5

Area of 3D triangle and then 3D rectangle

S = 1/2hbl

S= 1/2*4*5*8.5

S = 85 inch

+

S= blh

S = 5*6*8.5

S = 255 inch

S = 340 cube inches

B. 340 cubic inches

Divide shape into a rectangular prism and triangular prism:

HEIGHT of triangular prism:
10 in. - 6 in. = 4 in.

VOLUME of triangular prism (1/2 • l • w • h):
1/2 • 5 in. • 8.5 in. • 4 in. = 85 in^3

VOLUME of rectangular prism (l • w • h):
5 in • 8.5 in. • 6 in. = 255 in^3

ADD THE VOLUME OF BOTH FIGURES:
255 in^3 + 85 in^3 = 340 in^3

FINAL ANSWER:

Step-by-step explanation:

2/3 a - 1/6 = 1/3

answer this math question asap pls​

Answers

Answer:

a=3/4

Step-by-step explanation:

1. Get 2/3a by itself.

•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.

•Because you only add and subtract like denominators

This will make it look like:

2/3a - 1/6 = 2/6

Then, add 1/6 to both sides to get 2/3a by itself.

It'll look like this:

2/3a = 3/6

2. Get a by itself.

•Multiply the reciprocal (opposite) of 2/3 to get a alone.

This will look like:

(3/2) • 2/3a = (3/2) • 3/6

a = 18/24

3. Simplify.

Find the largest number that can simplify the equation.

For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.

But the largest number you can divide both sides by is 6.

18 ÷ 6 = 3 and 24 ÷ 6 = 4.

3/4.

the answer is a= 3/4
