When 11 is subtracted from twice a number, the square root of the result is 4. Find the number.​

Answers

Answer: I think 27/2

Explanation:

Let number = x:

√(2x - 11) = 4

Now to get x, we undo the square root by squaring both sides:

[√(2x - 11)]² = 4²

(2x - 11) = 16

2x = 27

x = 27 / 2

Cell phone plan a cost 70 per month but gives you a free 500 dollar phone plan b coat 50 dollors but has no phone. How long would it take them to reach the same proce

Answers

Answer:

Number of month = 25 month

Step-by-step explanation:

Given:

Plan A $70 per month and $500 phone cost

Plan B $50 per month No phone

Assume;

Number of month = x

So,

50x + 500 = 70x

20x = 500

x = 25

Number of month = 25 month

Mr. Gonzalez drove 30 miles in March. He drove 5 times as many miles in March as he did in January. He drove 2 times as many miles in February as he did in January. How many miles did Mr. Gonzalez drive in February?

Answers

Answer:

12 miles

Step-by-step explanation:

Given information :

Mr. Gonzalez drove 30 miles in March. In January, she drove 1/5 as much as in March.

30 ÷ 5 = 6 miles in January

in JanuaryShe drove 2 times as many miles in February as she did in January. In January, she drove 30 miles.

Fred's art project involves a series of parallel stripes. If he starts by drawing the line 8x+2y=7, select all the equations that could represent lines that could also be drawn for his art project.

Answers

Options:

A. [tex]y-1 = 4(x + 8)[/tex]

B. [tex]y = -4x + 15[/tex]

C. [tex]16x + 4y = 9[/tex]

D. [tex]y=-4x[/tex]

E. [tex]4x + 2y = 3[/tex]

Answer:

B. [tex]y = -4x + 15[/tex]

C. [tex]16x + 4y = 9[/tex]

D. [tex]y=-4x[/tex]

Step-by-step explanation:

Given

[tex]8x + 2y = 7[/tex]

Required

Select all equations that could be used.

Equation that could be used in place of [tex]8x + 2y = 7[/tex] must have the same slope.

Calculating the slope of [tex]8x + 2y = 7[/tex]

Make y the subject

[tex]2y = 7 - 8x[/tex]

[tex]y = \frac{7}{2} - \frac{8x}{2}[/tex]

[tex]y = \frac{7}{2} - 4x[/tex]

[tex]y = - 4x + \frac{7}{2}[/tex]

Using y = mx + b

Where

[tex]m = slope[/tex]

The slope is -4

Option A.

[tex]y-1 = 4(x + 8)[/tex]

Open bracket

[tex]y - 1=4x + 32[/tex]

Collect Like Terms

[tex]y - 4x = 32 + 1[/tex]

[tex]y - 4x = 33[/tex]

Make y the subject

[tex]y = 4x + 33[/tex]

The slope of this line is 4;

Hence, it can not be used.

Option  B.

[tex]y = -4x + 15[/tex]

The slope of this line is -4;

Hence, it can be used.

Option  C.

[tex]16x + 4y = 9[/tex]

Solve for4y

[tex]4y=9 - 16x[/tex]

Solve for y

[tex]\frac{4y}{4} =\frac{9}{4} - \frac{16x}{4}[/tex]

[tex]y =\frac{9}{4} - 4x[/tex]

[tex]y = - 4x + \frac{9}{4}[/tex]

The slope of this line is -4;

Hence, it can be used.

D. [tex]y=-4x[/tex]

The slope of this line is -4;

Hence, it can be used.

E. [tex]4x + 2y = 3[/tex]

Solve for 2y

[tex]2y = 3 - 4x[/tex]

Solve for y

[tex]\frac{2y}{2} = \frac{3}{2} - \frac{4x}{2}[/tex]

[tex]y = \frac{3}{2} - 2x[/tex]

The slope of this line is -2;

Hence, it can not be used.

From the calculations above, equations B, C and D are equivalent

Answer:

Step-by-step explanation:

Which speed is the fastest? Group of answer choices LaTeX:

The formula for speed =

Distance (miles) / Time (hours)

A) 4 miles in 1/3 hours

= 4 / 1/3

= 4 ÷ 1/3

= 4 × 3

= 12 miles per hour

B)1/3 miles in 4 hours

=1/3 miles/4 hours

= 1/3 ÷ 4 miles per hour

= 1/3 × 1/4 miles per hour

= 1/12 miles per hour

C) 1/2 miles in 3 hours

= 1/2 miles / 3 hours

= 1/2 ÷ 3

= 1/2 × 1/3

= 1/6 miles per hour

The fastest speed is A, 4 miles in 1/3 houra

Carlos is picking 6/384 apples. Mateo is picking oranges of 10. How much did Mateo pick?

Answers

Question might be incomplete or incorrect so we'd have to assume Mateo took apples

Answer:

5/189 apples

Step-by-step explanation:

If Carlos picks 6/384 apples then there must be 384 apples available to pick from. Amount of apples left after Carlos picks =384-6=378 apples

If Mateo picks 10 apples after Carlos then how much apples Mateo has taken would depend on the number of apples available, hence the fraction of apples Mateo has taken = 10/378

Reduce to lowest terms to get 5/189 apples

Write the equation of a line perpendicular to y =
3
x-3 and whose y-intercept is (0,12).

Answers

y=1/3x+12

When writing an equation for a line that’s perpendicular, don’t forget to flip the slope to its reciprocal

Answer:

y=-1/3x+12

Step-by-step explanation:

The slope of a line that is perpendicular to another is the negative reciprocal of the first. The slope of the line is 3 so the negative reciprocal will be -1/3.

Using the point-slope formula we can solve for the  equation of a line with a slope of -1/3 and a point of (0,12).

The point slope formula is

y-y1=m(x-x1).

y-12=-1/3(x-0) -------------->Distribute: y-12=-1/3x ---------------> Isolate the y by moving the 12 to the other side. y=-1/3x+12

Find rhe x- and y- intercerpts of the following relationships.(There may be more then one)
[tex]3x^{2} + 2y^2 = 24[/tex]

Answers

Answer:

see explanation

Step-by-step explanation:

Given

3x² + 2y² = 24

To find the x- intercepts , let y = 0 in the equation and solve for x

3x² + 2(0)² = 24, that is

3x² = 24 ( divide both sides by 3 )

x² = 8 ( take the square root of both sides )

x = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex] ← x- intercepts

To find the y- intercepts. let x = 0 in the equation and solve for y

3(0)² + 2y² = 24 , that is

2y² = 24 ( divide both sides by 2 )

y² = 12 ( take the square root of both sides )

y = ± [tex]\sqrt{12}[/tex] = ± 2[tex]\sqrt{3}[/tex] ← y- intercepts
