Answer:

A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.

Step-by-step explanation:

Given

[tex]3x - 3y = 1[/tex]

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

Required

A good first step

A good first step is to eliminate x and this is done as follows:

Multiply [tex]3x - 3y = 1[/tex] by 2 (gotten from coefficient of x in the second equation)

Multiply [tex]-2x+ 4y = 2[/tex] by 3 (gotten from coefficient of x in the first equation)

This gives:

[tex]6x - 6y = 2[/tex]

[tex]-6x + 12y = 6[/tex]

Add both equations

[tex]6x - 6x - 6y + 12y = 2 + 6[/tex]

[tex]6y = 8[/tex]

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

Hence (a), is true

Answer:

the simple interest rate is 18.00%

Step-by-step explanation:

The computation of the simple interest rate is shown below:

Amount = Principal × (1 + rate)^years

$4,935 = $3,000 × (1 + rate)^3

After solving it, the rate of percentage is 18.00%

Hence, the simple interest rate is 18.00%

Answer:

b + 1.75f

Step-by-step explanation:

1.75 cups are used for every loaf of pumpkin bread.

Answer:

f(4/7)=b

Step-by-step explanation:

3+1/2=7/2

(7/2)x=2

x=4/7

the constant of the equation is 4/7

so take f and b and put f in place for 7/2 cups and b for 2 loaves of bread.

f(4/7)=b

Hope that helps :)

Answer:

-0.5

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

         = (-4 - 1)/(0-(-10))

         = (-5)/10

         = -0.5

Answer:

It’s -1/2

Step-by-step explanation:

Answer:

$3283.2

Step-by-step explanation:

Given data

Principal= $2700

Rate= 4%

Time= 5 years

Required

the final Amount A

The compound interest formula is

A=P(1+r)^t

Substitute

A=2700(1+0.04)^5

A=2700(1.04)^5

A=2700*1.216

A=$3283.2

Hence the balance in the account after 5 years is $3283.2

Given:

The sides of a triangle are 3 cm, 5 cm, 7 cm.

To find:

The angle classification of the given triangle.

Solution:

Let a,b,c are the three sides of a triangle ABC, where c is the longest side.

1. Triangle ABC is acute, if [tex]c^2<a^2+b^2[/tex].

2. Triangle ABC is acute, if [tex]c^2=a^2+b^2[/tex].

3. Triangle ABC is acute, if [tex]c^2>a^2+b^2[/tex].

The sum of square of two smaller sides is

[tex]3^2+5^2=9+25[/tex]

[tex]3^2+5^2=34[/tex]

In the given triangle 7 cm is the longest sides. So,

[tex]7^2=49[/tex]

It means,

[tex]7^2>3^2+5^2[/tex]

Since [tex]c^2>a^2+b^2[/tex], therefore, the triangle ABC is an acute triangle.

wow so what's the question then

Given:

Some boxes are fully colored.

Each fully colored ten block represents 1 whole.

The number of colored boxes will be divided into 11 equal part.

To find:

The number of squares need to be colored on each of the 10 blocks.

Step-by-step explanation:

From the given figure, it is clear that,

Number of colored box = 55

The number of colored box will be divided into 11.

[tex]\dfrac{55}{11}=5[/tex]

Therefore, 5 squares need to be colored on each of the 10 blocks.

Answer:

13.42

Step-by-step explanation:

[tex]\sqrt{180} =6\sqrt{5} \\\\6\sqrt{5} =13.42[/tex]

Answer:

answer: [tex]6\sqrt{5}[/tex]

Step-by-step explanation:

[tex]\sqrt{180} = \sqrt{4 * 9 * 5} \\= 2*3\sqrt{5} \\= 6\sqrt{5}[/tex]

Answer: b, d

Step-by-step explanation:

Corresponding angles are formed when two parallel  straight lines are cut by a transversal

[tex]\angle b=62^{\circ}[/tex]

In the figure, [tex]\angle d\ \text{and}\ 62^{\circ}[/tex] are alternate angle

[tex]\therefore \angle d=62^{\circ}[/tex]

Answer:

Principal = Total ÷ (1 + Rate)^years

That formula is found here: http://www.1728.org/compint2.htm

Principal = 3.000 / (1.03) ^ 15

Principal = 3.000 / 1.5579674166

Principal = $1,925.59

Answer:

0.57

Step-by-step explanation:

The 7 is in the hundredths place. Next to it is a 4. 4 does not round up, therefore making the answer 0.57.

Answer:

There are no solutions

Step-by-step explanation:

9x+18−5x=2+4x

Step 1: Simplify both sides of the equation.

9x+18−5x=2+4x

9x+18+−5x=2+4x

(9x+−5x)+(18)=4x+2(Combine Like Terms)

4x+18=4x+2

4x+18=4x+2

Step 2: Subtract 4x from both sides.

4x+18−4x=4x+2−4x

18=2

Step 3: Subtract 18 from both sides.

18−18=2−18

0=−16

Answer:

There aren't any values of x that would make the equation true.

NO SOLUTION

Answer:

How tightly packed an object's particles are.

7.4 in fix fraction will look like this:

[tex]7 \frac{2}{5} [/tex]

Answer:

4.5

Step-by-step explanation:

Given the expression ab-0.5

We are to evaluate the expression if a =1 and b = 5

ab- 0.5

=  1(5) - 0.5

= 5 - 0.5

= 4.5

Hence the required result is 4.5
