Please help me what is a NOW a/4 − 5/6 = −1/2

Answers

Answer:

Step-by-step explanation:

Change the denominator of the 1/2 to sixths. Multiply the top and bottom by 3 to get 3/6

[tex]\frac{a}{4}-\frac{5}{6}=-\frac{3}{6} \\[/tex]

Add 5/6 to both sides and simplify

[tex]\frac{a}{4} =\frac{1}{3}[/tex]

Multiply both sides by 4 to get

a=4/3

Multiply numbers
A/4 -1 x 5/6 = -1/2
A/ 4 - 5/6 =-1/2
Add 5/6 to both sides of the equation
A/4 -5/6 =1/2
A/4 -5/6+5/6 =-1/2 +5/6
Simplify
Add the numbers
A/4 =1/3

Multiply all terms by the same value to eliminate fraction denominators
A/4 = 1/3
4x a/4 =4x1/3
Simplify

Cancel multiplied terms that are in the denominator
Multiply the numbers
A=4/3
Solution
A=4/3

StartRoot 40 EndRoot units

Answers

Answer:

the length of the other altitude of the given parallelogram will be 6 units and option B is the correct choice.

The length of the other altitude in the parallelogram will be B. 6 units.

How to calculate the altitude?

The equation to find the altitude in the parallelogram will be:

Altitude 1 × Vertical base = Altitude 2 × Horizontal base

✓22.5 × ✓40 = Altitude 2 × 5

30 = Altitude 2 × 5

Altitude 2 = 30/5

Answer:

∠B = 141

Step-by-step explanation:

n - > number of sides

n = 7

Sum of all interior angles = (n -2 ) * 180

                                         = 5 * 180 = 900

∠B + 148 + 90 + 142 +  130 + 129 + 120 = 900

∠B  + 759 = 900

∠B = 900 - 759 = 141

Deborah spent $70 on food and clothes. She spent $26 more on clothes than on food. On your worksheet, solve the question and write your answer below. How much did she spend on food and how much did she spend on clothes?

Answers

Answer:

She spent $22 on food, and $48 on clothes.

Step-by-step explanation:

Let's define the variables:

C = amount of money that Deborah spent on clothes

F = amount of money that Deborah spent on food.

We know that she spent in total $70, then we have the equation:

F  + C = $70

And we know that she spent $26 more on clothes than on food, then we have the equation:

C = F + $26

This means that we have a system of equations:

F + C = $70

C = F + $26

To solve these type of systems, we usually start by isolating one variable in one of the equations. Here we can see that C is already isolated in the second equation.

Now we can replace it in the first equation.

F + (F + $26) = $70

Now we can solve this for F.

2*F + $26 = $70

2*F = $70 - $26 = $44

F = $44/2 = $22

So she spent $22 on food.

Now we can use the equation:

C = F + $26

To find how much she spent on clothes, where we need to replace F by the value we found.

C = $22 + $26 = $48

She spent $48 on clothes.

Answer:

the x coordinate is 5

Step-by-step explanation:

the x coordinate would be wherever the dot is on the horizontal line

the y coordinate would be wherever the dot is on the vertical line

as shown on the graph, the point is located at numbers (5,4). We see here that on the x-axis, it is 5, making 5 the x coordinate. 4 will be the y-coordinate since it is on the y-axis. Here’s a tip.
the x-axis(line) goes horizontal and the y-axis goes vertical. Just look at what numbers the x and y axis give you on the point and you’ll find your answer.

what is the slope intercept equation for the following line? 

(see image)

Answers

Answer:

y = x + 1

Step-by-step explanation:

You can immediately read off the y-intercept from the graph:  (0, 1).  The slope of this line is negative.  Choosing two different points on this line leads to finding the slope of the line:  (0, 1) and (2, -1)  Going from the first point to the other, we see that x (the run) increases by 2 and y(the rise) decreases by 2.  Thus, the slope is m = rise/run = 2/2 = 1.

The slope-intercept equation of this line is therefore y = x + 1.

Answer:

y=-1x+1

Step-by-step explanation:

To find the slope, we can use rise (vertical) over run (horizontal).

m=rise/run

We can see that from the first point to the second point,  x increased by 2 and y decreased by 2.

The rise is -2 and the run is 2.

m=2/-2=-1.

The slope is -1.

Now let's find the y-intercept (the point where x=0, or where the line crosses the y-axis.)

This point is at (0,1), so b=1.

The y-intercept is 1.

This is the format for slope-intercept form: y=mx+b.

The slope-intercept equation is y=-1x+1.

The width of a rectangle is 32 inches. The width of the rectangle decreased by 8 inches and its length also changed. The area of the rectangle remains the same, 1,440 square inches. What is the new length of the rectangle?

Answers

Answer:

60 in

Step-by-step explanation:

Area = length x width

Area is constant at 1440 in^2

For first rectangle: W1 and L1

For second rectangle: W2 and L2

W1 = 32 in

W2 = W1 - 8 in = 24 in

1440 in^2 = L1 x 32 in = L2 x 24 in

L1 = 45 in

L2 = 60 in

Answers

Answer:

C. Every year the number of subscribers is estimated to increase by 8% over the

number of subscribers the year before.

Step-by-step explanation:

Using the formula :

S = 20,000 (1 + 0.08)^y to estimate ;

S = number of subscribers ; y = years

The expression : (1 + 0.08)^y

0.08 = 0.08 * 100% = 8%

(1 + 0.08)^y represents a continous growth or increase in the number of subcsribers by 8% over the number of subscribers the preceeding year
