Answer

If you didn't it there wouldn't be an easy method to do the problem.Having the same denominator is the easiest method and is pretty basic.If you didn't have a common denominator such as:5/8 + 7/6, it would be virtually impossible to solve.

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Answer:

the customer saves 35%

Step-by-step explanation:

The distances between two points are required.

The Distance from house to school to grocery store is greater than Distance to from house to school to community center.

The points are

\(H(-4,5)\)

\(S(-4,3)\)

\(C(6,3)\)

\(G(-4,-9)\)

The distance between the HS is

\(|HS|=\sqrt{(3-5)^2+(-4-(-4))^2}=2\)

Distance between SG

\(|SG|=\sqrt{(-4-(-4))^2+(-9-3)^2}=12\)

Distance from house to school to grocery store is

\(2+12=14\)

Distance between the SC

\(|SC|=\sqrt{(6-(-4))^2+(3-3)^2}=10\)

Distance to from house to school to community center

\(2+10=12\)

So, the Distance from house to school to grocery store is greater than Distance to from house to school to community center.

Answer:

t = 5

Step-by-step explanation:

by using guess and check, we can plug in the numbers 5 into t, 3 into s, and 10 into r.

if t = 5, then r must mean twice that number meaning it is 10.

the remainder would be s which means it is 3.

r+s=13 into 10 + 3 = 13

2t+s=13 into 2(5) + 3 = 13

Answer:

Step-by-step explanation:

1. 3x + 2y - 2x + y + 12 is equivalent to x + 3y + 12

2. 4y + 3y + 3x - 6y - 10 - 2 is equivalent to 3x + y - 12

3. x + 3y + 2x - 3x + 7 + 5 is equivalent to 3y + 12

4. I do not know unfortunately

Answer:

See attached image

Step-by-step explanation:

To solve this, first simplify the compound expressions - the ones with multiple x, y terms and see which of the other expressions matches the simplified expression

I will tell you how to solve one of the more complex expressions; the technique is the same for the rest

Let's take the very last expression
4y + 3y + 3x - 6y -10 - 2

To simplify,

group like terms:

=(4y + 3y - 6y) + 3x +(-10 -2)

= y + 3x - 12

Rewriting with x before y gives
3x + y - 12

and there is a matching 3x + y - 12

4y + 3y + 3x - 6y -10 - 2   ⇔  3x + y - 12

The solution is in the attached image

Answer:

slope = 1 and y- intercept = 4

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (2, 6) ← 2 points on the line

m = \(\frac{6-4}{2-0}\) = \(\frac{2}{2}\) = 1

The y- intercept is the y- coordinate of the point where the line crosses the y- axis.

Here the y- intercept = 4

Answer:

312km

Step-by-step explanation:

Answer:

225 and 243.4

Step-by-step explanation:

Area of triangle = bh/2

A = 4*4.6/2

A = 9.2 cm sq

A of 2 triangles = 9.2*2 = 18.4 cm sq

Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq

A of 3 rectangles = 75*3 = 225 cm sq

Now, LSA = 225 cm sq. (excluding the triangles)

TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

Step-by-step explanation:

If we are given the equation of a line in this format:

y=mx+b

then it is quite simple to find the gradient and y-intercept.

In the format:

y=mx+b

the m represents the gradient (slope) and b represents the y-interpcept.

1) y=2x+3

gradient= 2

y-intercept= 3

2) y=x-5

gradient=  1

y-intercept= -5

3) y=-2x-4

gradient= -2

y-intercept= -4

4) y=5-x

gradient= -1

y-intercept= 5

5) y=3x+8

gradient= 3

y-intercept= 8

6) y= 1/4x+3

gradient= 1/4

y-intercept= 3
