The value of the expression is -1.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

63 ÷ 7 x 3 - 4

Using PEMDAS rule of operation.

We multiply first.

So,

= 63 ÷ 21 - 4

Using the division.

= 63/21 - 4

= 3 - 4

= -1

Thus,

Answer: 735

Step-by-step explanation:

Answer:

Let s be the distance to Grandma’s and v the speed they went to get to Grandma’s.

So s=8v, because it took them 8 hours to get there.

Coming back they travelled s+20 miles. Since s=8v we can write this as 8v+20 miles.

Their speed was reduced by 10mph so that’s v-10. It took them 10 hours to return so:

8v+20=10(v-10); 8v+20=10v-100; 120=2v

so v=60mph. This is their average speed going to Grandma’s.

The maximum cost Dorothy should pay for the car to stay within her monthly budget amount is $23,518.84. See the explantion below.

A budget is a financial plan that takes into account both income and costs. In other words, it's a projection of how much money you'll make and expend over a specific time period, such as a month or a year.

The calculation that justified the above amount is solved as follows:

Given that:

Rate = 4%

Time = 4 years

The monthly payment is $490, to determine the amount (maximum) in 4 years, we use the Compound Interest formula:

                                          A = P (1+ (r/n)ⁿᵇ

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

b = number of time periods elapsed

A = P (1 + (0.04/1)^(1x4)

A = P (1.04)⁴ in four years

Hence, given that the monthly payment over the four-year period is $490, we say:


P [(1.04)⁴] /12 x4 = 490

⇒ P (1.04)⁴ = 490 x 48
P = (490 x 48)/1.1699
P = 20104.2824173

P [tex]\approx[/tex] 20,104

The maximum amount payable hence

= 20,104 (1.04)⁴

A = 23518.837

A [tex]\approx[/tex] 23,518.84

Mila bought stock in company two years ago that was worth x dollars. During first year that she owned the stock, it decreased by 35%. During second year the value of the stock decreased by 32%, an expression in terms of a that represents the value of the stock after the two years have passed is 2x+0.67.

It is not always obvious from the context what a % is in relation to because of inconsistent usage. The typical meaning of a "10% rise" or "10% decline" in a quantity is that this refers to the quantity's starting value. As an illustration, the new price of a $200 item would be $220 if the price increased by 10%, or $20. The final price is equal to 100% of the starting price (100% + 10% = 110%).

Other instances of % changes include:

If a quantity is increased by 100%, the final amount will be 100% more than the original amount (100% of initial + 100% of increase = 100% of initial). The quantity has therefore doubled.

If an amount is increased by 800%, the final sum will be nine times as large as the original (100% + 800% = 900% = 9 times as large).

When something is reduced by 60%, the final sum equals 40% of the original (100% - 60% = 40%).

A reduction of 100% results in a final value of 0% (100% - 100% = 0%).

In general, if a quantity is changed by x percent, the final amount will be 100 + x percentage of the original amount, or (1 + 0.01x) times the original amount.

The proportionality is the direct relation of two variables thus the constant of proportionality of the given graph is 1/2.

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

For example x ∝ y

The graph of seconds and ounces has shown.

If we look at the graph it is clear that as the ounces are increasing the seconds are also increasing. Therefore, it is a direct proportion.

Let's suppose the proportion is x ∝ y where x is ounces while y is seconds.

Removing proportionality,

x = ky

k = x/y

Substitute,(x,y) = (1,2)

k = 1/2

Answer:

Step-by-step explanation:

The equation of the perpendicular line in slope intercept form is

y = (-3/4)x - 9/4.

The slope is defined as the rate of change of the y-axis with respect to

x-axis.

We know equation of a line in slope intercept form is y = mx + b, where slope = m and y-intercept = b.

We also know that perpendicular lines have a slope that is negative reciprocal of each other.

Given line is 8x - 6y = -5.

-6y = - 8x - 5.

-y = (-8/6)x - 5/6.

-y = (-4/3)x - 5/6.

y = (4/3)x + 5/6.

∴ Slope(m) = 4/3.

So, the line which is perpendicular has a slope(m) = -3/4 with points (1,-3).

∴ - 3 = (-3/4)(1) + b.

- 3 = -3/4 + b.

b = 3/4 - 3.

b = -9/4.

∴ The equation of the line is y = (-3/4)x - 9/4.
