Answer: x= -2 and y=7

Step-by-step explanation:

4×20x+11y=37

20×4x+3y=13

Using elimination method

80x+44y=148

80x+60y=260

-16y/-16=-112/-16

Y=7

Substitute for Y in equation (1)

20x+ 11(7)=37

20x+77=37

20x=37-77

20x/20= -40/20

X= -2

therefore, x=-2 and y=7

What is the unit rate for 16 ounces (pint) at $3.93?
Juli2301 [7.4K]

Answer:

25 cents/ounce

Step-by-step explanation:

The unit rate means how much is one of the thing you are working with.  In this case, the unit rate of a pint (16 ounces) is how much just one ounce will cost.  So divide $3.93 by 16

$3.93/16 =  $0.245625

Since we're working with money, round to the nearest hundredth

Unit rate is $0.25 per ounce, or 25 cents per ounce

Help me please. I don’t understand this math. My math teacher is mean. :(((((
Verdich [7]

Answer:

The height of the given rectangular prism is 5cm.

Step-by-step explanation:

Given that the volume of the rectangular prism is 5cm^3

And length is \frac{3}{4} and width is 1\frac{1}{3}

That is V=5cm^3[/tex] , l=\frac{3}{4}cm and w=1\frac{1}{3}cm

We have the  volume of the rectangular prism V=lwh cubic centimeter

V=lwhcm^3

Substituting the values in above formula

5=\frac{3}{4}\times 1\frac{1}{3}\times h

5=\frac{3}{4}\times \frac{4}{3}\times h

5=1\times h

5=h

Rewritting as below

h=5cm

Therefore the height is 5cm

Answer:

y = 3x + 2; y = -x + 4

Step-by-step explanation:

Slope intercept form is in y = mx + b, where m is the slope and b is the y-intercept. In the first image, 2 is the y-intercept and 3 is the slope, yielding the equation y = 3x + 2.

For the second, 4 is the y-intercept and -1 is the slope, so the answer to the second image is y = -x + 4.
