Answer:

equation 2into minus 3 into equation 1

8x+ 3y= -28

-3x-3y=18

----------------

5x=10

x =2

put value of y in equation 2

8 into 2+3y=-28

16+3y= -28

3y= -28+16

3y= -12

y= -4

What is the volume of the triangular prism?

maxonik [38]

Answer:

Step-by-step explanation:

The volume of the triangular prism is

$V=A_{base}\cdot h,$

where

h = height

Base = triangle.

In your case,

$A_{base}=\dfrac{1}{2}\cdot 4\cdot 4=8\ ft^2\\ \\h=1\ ft,$

then

$V=8\cdot 1=8\ ft^3$

Answer:

See Explanation

Step-by-step explanation:

Given

See attachment

Solving (1): What is asked

The requirement of the question is to determine the difference between the amount of sugar used between yesterday and today

Solving (2): The given facts

$Yesterday = \frac{9}{10}kg$

$Today = \frac{3}{5}kg$

Solving (3): Operation to be used

We use subtraction operation

Solving (4): The mathematical sentence

$D = Yesterday - Today$

$D = \frac{9}{10}kg - \frac{3}{5}kg$

D represents the difference

Solving (5): The solution

$D = \frac{9}{10}kg - \frac{3}{5}kg$

Take LCM

$D = \frac{9 - 6}{10}kg$

$D = \frac{3}{10}kg$

Answer:

( C ) ΔMLN ≅ΔTSR

Step-by-step explanation:

Okay I got you!

So if the triangle <u>str</u> was flipped and rotated the other way then you will see that they are similar. They are asking what other "pairs" could you do to make it equivalent. Since M = T then you got your first pair. Next you go to N and when you look at the shape you'll see it will be S. N=S. And the last one would be L=R. I hope I was helpful enough! uwu Try to draw them out it will be helpful!!

The angle measurements in the diagram are represented by the following expressions

KIM [24]

Answer:

x = 12

∠A = 144

Step-by-step explanation:

+ We have: ∠A = ∠C (alternate interior)

∠D = ∠C ( vertically opposite angles)

=> ∠A = ∠C (because = ∠C)

=> 10x + 24 = 6x + 72

=> 10x - 6x = 72 - 24

4x = 48

x = 12

+ ∠A = 10x + 24

∠A = 10 x 12 + 24

∠A = 144
