How many quarters are there in 2¼ ?​

Answer:

x = –2

Step-by-step explanation:

– 6(1+4x) = –x +40

–6 – 24x = –x +40

24x –x = –6 –40

23x= – 46

x= – 46 / 23

x= – 2

Answer:

3/6 or 1/2

Step-by-step explanation:

⇒ out of 6 blocks 3 are shaded so, it will be 3/6

⇒ out of 6 blocks 3 are shaded (3 is half of 6) so, it will be 1/2

Answer:

Answer: 3/6 or 1/2

Step-by-step explanation:

Basically there are six bars and we are to find the fractional part of the blue bars. The fractional part of the blue bars is 3/6 or 1/2.

Answer:

–3x + y =1

y= 1 +3x

4x + y =8 —> 4x + ( 1 + 3x ) = 8

7x + 1 = 8 —> 7x = 8 – 1 —> 7x = 7

x = 7/7 —> x = 1

y= 1 + 3x —> y = 1 + 3 (1) —> y = 1+ 3

y= 4

(x , y ) —> ( 1 , 4 )

Step-by-step explanation:

Answer:

1/32

Step-by-step explanation:

First you must multiply the 3 and the -5 because the -5 is out of the parenthases. then you will get 2^-15. You cannot have a negative exponent so you chance it to 1/2^15. Then simplify to get the answer

Answer:

Reason 4 is wrong in Ethan's solution.

Step-by-step explanation:

Reason 4 is incorrect because at this step in the answer we already have one  variable which is unknown on the left side and then one constant which can be seen on the right. So, instead of multiplying the fractions the way Ethan is doing, all you need to do now is just simplify the expression instead of complicating the step.

Answer:

Angle Z = Angle V (as it is already said that ZY = VY and their ending points are Z and V respectively

Step-by-step explanation:

angle z = angle v​ can be proved by the SAS (Side angle side) Property

XZ = TV (Given)

Angle Z = Angle V (as it is already said that ZY = VY and their ending points are Z and V respectively

ZY = VY ( Given )

Answer:

480

Step-by-step explanation:

Let x be the calories in 4 cups

Set it up

[tex]\frac{90}{\frac{3}{4}}=\frac{x}{4}[/tex]

Step 1: Switch sides

[tex]\frac{x}{4}=\frac{90}{\frac{3}{4}}[/tex]

Step 2: Apply fraction rule

[tex]\frac{x}{4}=\frac{90\cdot \:4}{3}[/tex]

Multiply

[tex]\frac{x}{4}=\frac{360}{3}[/tex]

Divide

[tex]\frac{x}{4}=120[/tex]

Step 3: Multiply both sides by 4

[tex]\frac{4x}{4}=120\cdot \:4\\\\=480[/tex]

There are 480 calories in 4 cups of the cereal.

Step-by-step explanation:

because -5 is parallel to AB

The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]

Let the sides of Juan's triangle be x, y and z. So:

[tex]x = 5 \\ y = 8\\ z = 12[/tex]

The perimeter (J) of Juan's triangle is calculated by adding all sides.

So:

[tex]J =x +y +z[/tex]

This gives:

[tex]J =5 + 8 + 12[/tex]

[tex]J =25[/tex]

From the question, we understand that:

The perimeter (S) of Stephanie's triangle is half that of Juan.

This means that:

[tex]S = \frac 12J[/tex]

Substitute 25 for J

[tex]S = \frac 12 \times 25[/tex]

Hence, the numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]

Answer:

10+15i/13

Step-by-step explanation:

This question is about complex numbers.

so,

in this type of questions we have to multiply this fraction by the conjugate of the denominator

   conjugate of the denominator is  3-2i

    1)    5i(3-2i)/(3+2i)(3-2i)

    2) 15i-10i^2/9-4i^2   ( we know that i^2 = -1 )

    3) 15i+10/9+4

Answer:

7/8

Step-by-step explanation:

1/4 + 5/8 = 2/8 + 5/8 = 7/8

= amount used for pepper and tomatoes

2 1/2 - 3/4 = 5/2-3/4 = 10/4 -3/4 = 7/4

= total amount used

so

7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce
