Answer:x=7/5

Step-by-step explanation:

Answer:

x= [tex]\frac{7}{\\5}[/tex]

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x−5=2−x

4x+−5=2+−x

4x−5=−x+2

Step 2: Add x to both sides.

4x−5+x=−x+2+x

5x−5=2

Step 3: Add 5 to both sides.

5x−5+5=2+5

5x=7

Step 4: Divide both sides by 5.

[tex]\frac{5x}{5}[/tex]  = [tex]\frac{7}{5}[/tex]

Answer:

Solution given;

3-(7-3x)=2x+2

3-7+3x=2x+2

3x-2x=2+4

x=6 is your answer.

To find your answer I believe you need to add or multiply your exponents and since their is already three p then your answer is 3p^ and then you put your answer. Hopefully this helps.

Answer:

7/12

Step-by-step explanation:

You need to get -7 to be a positive number so that its zero

-7+7=0

Then just add the denominator!!!

0/12=0

I hope this helps!!!!

Answer:

63.33 or 190/3

Step-by-step explanation:

1. vertical opposite angles are equal

2. corresponding angles some up to 180°

=> 3x - 20 + 10 = 180

=> 3x = 180+10

=> 3x = 190

=> x = 190/3

=> x = 63.333333333333333

Answer:

Step-by-step explanation:=(1+sinA)2+cos2A/cosA(1+sinA)

=1+sin2 A+2sin A+cos2 A/cos A(1+sin A)

=1+2sin A+1/cos A(1+sin A)

=2(1+sin A)/cos A(1+ sin A)

=2sec A

Answer:

see explanation

Step-by-step explanation:

Consider the left side

[tex]\frac{1+sinA}{cosA}[/tex] + [tex]\frac{cosA}{1+sinA}[/tex] ← combine into a single fraction

= [tex]\frac{(1+sinA)^2+cos^2A}{cosA(1+sinA)}[/tex] ← expand and simplify numerator

= [tex]\frac{1+2sinA+sin^2A+cos^2A}{cosA(1+sinA)}[/tex] [ sin²A + cos²A = 1 ]

= [tex]\frac{1+2sinA+1}{cosA(1+sinA)}[/tex]

= [tex]\frac{2+2sinA}{cosA(1+sinA)}[/tex] ← factor out 2 on the numerator

= [tex]\frac{2(1+sinA)}{cosA(1+sinA)}[/tex] ← cancel (1 + sinA) on numerator/ denominator

= [tex]\frac{2}{cosA}[/tex]

= 2secA = right side, thus verified

Answer:

736

Step-by-step explanation:

789-53=736

Answer:

4.46cm

Step-by-step explanation:

Volume of a frustum is expressed as;

V = (1/3) * π * h * (r₁² + r₂² + (r₁* r₂))

h is the height of the frustum

r₁ and r₂ are the radii of its ends

V is the volume

Given

V = 9100cm₃

r₁ = 10cm

r₂ = 30cm

Substitute

9100 = (1/3) * (3.14) * h * (10² + 30² + (10* 30))

9100 = 1/2(3.14)*h*(100+900+300)

9100 = 1.57*h*(1300)

9100 = 2,041h

h = 9100/2,041

h = 4.46cm

Hence the height of the cap is 4.46cm

Answer:

0.21186

Step-by-step explanation:

We solve the above question using the z score formula.

z = (x-μ)/σ, where

x is the raw score = 3100g

μ is the population mean = 3500g

σ is the population standard deviation = 500g

z = 3100 - 3500/500

z = -0.8

Probability value from Z-Table:

P(x<3100) = 0.21186

The probability that a baby is born that weighs less than 3100g is 0.21186

Answer:

3 Whole pieces

Step-by-step explanation:

A turkey was cut into 10 equal pieces.

For Katie

If Katie ate 2/10 of the turkey

Number of Whole pieces of turkey Katie ate =

2/10 × 10 whole pieces = 2 whole pieces

For Lorenzo

Lorenzo ate 5/10 of the turkey

Number of Whole pieces of turkey Lorenzo ate =

5/10 × 10 whole pieces = 5 whole pieces

how many whole pieces of the turkey are left?

This is calculated as:

10 pieces - (2 piece + 5 pieces)

10 pieces - 7 pieces

= 3 pieces

Therefore, we have 3 whole pieces of turkey left.

Answer:

3 Whole pieces

Step-by-step explanation:

A turkey was cut into 10 equal pieces.

For Katie

If Katie ate 2/10 of the turkey

Number of Whole pieces of turkey Katie ate =

2/10 × 10 whole pieces = 2 whole pieces

For Lorenzo

Lorenzo ate 5/10 of the turkey

Number of Whole pieces of turkey Lorenzo ate =

5/10 × 10 whole pieces = 5 whole pieces

how many whole pieces of the turkey are left?

This is calculated as:

10 pieces - (2 piece + 5 pieces)

10 pieces - 7 pieces

= 3 pieces

Therefore, we have 3 whole pieces of turkey left.

Answer:

1728ft³

Step-by-step explanation:
