Answer:

The first equation should be multiplied by - 7 and the second equation by 3

Step-by-step explanation:

Given

[tex]9x + 3y = -18[/tex] -- (1)

[tex]8x + 7y = 10[/tex] -- (2)

Required

How to eliminate y

In (1), the coefficient of y = 3

In (2), the coefficient of y = 7

Multiply the first equation by -7

[tex]-7(9x + 3y = -18)[/tex]

[tex]-63x -21y = 126[/tex] --- (3)

Multiply the second by 3

[tex]3(8x + 7y = 10)[/tex]

[tex]24x + 21y = 30[/tex] -- (4)

Add the results together:

[tex]-63x -21y = 126[/tex]

[tex]24x + 21y = 30[/tex]

[tex]-------------------------[/tex]

[tex]-63x + 24x -21y +21y = 126+30[/tex]

[tex]-63x + 24x = 126+30[/tex]

See that y is eliminated

Answer:

12 times

Step-by-step explanation:

1 quart = 32 ounces

3 quart = x

x = 3 × 32 ounces

x = 96 ounces

The number of times of he need to fill an 8-ounce measuring cup to fill the pot is calculated as:

= 96 ounces/8 ounces measuring cup

= 12 times

Therefore, Alan needs to fill an 8 ounce measuring cup 12 times in order to fill the pot of soup.

Answer: The measure of angle P = 29°

Step-by-step explanation:

We can find the interior supplementary angle at Q by subtracting

180- 56 = 124

The sum of the interior angles must be 180, so we can add ∠Q + ∠R

124 + 27 = 151

Then subtract that from 180:

P = 180 - 151

P = 29°

Answer:

The trip contains 4 miles.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given that A taxi charges $1.75, meaning the initial condition of the trip is to charge $1.75.

Thus, y-intercept b = 1.75

Also, the taxi charges a fee of $0.75 for each mile traveled.

Thus, rate of change or slope m = 0.75

Let 'y' be the total cost

Let 'x' be the number of miles

Given that the total cost of a ride, without a tip, is $4.75.

so substitute y = 4.75, rate of change or slope m = 0.75, and the y-intercept b = 1.75 in the slope-intercept form of the line equation

y = mx + b

4.75 = 0.75(x) + 1.75

switch sides

0.75(x) + 1.75 = 4.75

subtract 1.75 from both sides

0.75x + 1.75 - 1.75 = 4.75 - 1.75

0.75x = 3

divide both sides by 0.75

0.75x/0.75 = 3/0.75

x = 4 miles

Therefore, the trip contains 4 miles.

Answer:

The unknown number = 11

Step-by-step explanation:

Let

The unknown number = x

9 times a number is increased by 30

= 9x + 30

140 is decreased by the number

= 140 - x

9x + 30 = 140 - x

Collect like terms

9x + x = 140 - 30

10x = 110

x = 110 / 10

x = 11

Check:

9x + 30

9(11) + 30

= 99 + 30

= 129

140 - x

= 140 - 11

= 129

Answer:

43

Step-by-step explanation:

Let x=lucy and y=chuck

we know that in total they found 92 arrowheads which means that

x+y=92

we also know that lucy found 6 more than chuck which means taht

x-6=y

Let's solve this through substitution

Looking at the second equation we know exactly what y is equal to in terms of x so we can plug this in (x-6) whenever we see a y in the first equation

so we have

x+(x-6)=92

solve for x and get

2x=98

x=49

Now that we know what x is equal to we can solve for y

49-6=y

y=43

This means that lucy found 49 and chuck found 43

Answer:

x = 10

Step-by-step explanation:

You need to isolate x, so divide by 13. 130/13 = 10.

Simplified, x = 10.

The solution to the given equation is 10.

The given equation is 13x = 130.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, transpose 13 to the other side of the equation, we get

13x = 130

x=130/13

x=10

Therefore, the solution to the given equation is 10.

Answer:

-3/5

Step-by-step explanation:

Slope is calculated with the formula m=(y_2 - y_1)/(x_2-x_2). The starting point I put as (0,0) and the finish is (5,-3). I used one city block is equal to one. Thus 3 blocks south(y-axis), is -3 and 5 east(x-axis) is 5. So plug into the equation with y_2 as -3 and x_2 as 5 then y_1 and x_1 both as zero. Thus slope=m= -3/5.

Answer:

$3,072

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.2%/100 = 0.032 per year,

then, solving our equation

I = 32000 × 0.032 × 3 = 3072

I = $ 3,072.00

The simple interest accumulated

on a principal of $ 32,000.00

at a rate of 3.2% per year

for 3 years is $ 3,072.00.

Answer:

1,350 square cm

Step-by-step explanation:

As we all know, we have to square a dimension of length to get the dimension of an area

So in this case, since the dimension of the length is increasing by a factor of 3, the dimension of the area will be increasing by a factor which is square the factor by which the dimension of the side is increasing

Thus, we have the area dimension increase by a factor of 3^2 = 9 times the area of the smaller

nonagon

So the area of the bigger nonagon will be :

150 * 9 = 1,350 square cm

Answer:

34.134%

Step-by-step explanation:

Given :

Normal distribution ;

Mean, m = 100 ; Standard deviation, s = 10

Percentage score between 90 and 100

P(90 ≤ x ≤ 100)

Recall : Zscore = (x - m) / s

P[(90 - 100) / 10 ; (100 - 100) / 10]

P[(10/10 ; 0 / 10)]

P(Z ≤ 1) - P(Z≤0) (Using Z probability calculator)

0.84134 - 0.5

= 0.34134

= 0.34134 * 100%

= 34.134%

True.

Step-by-step explanation:

Answer:

32

Step-by-step explanation:

So since you can see that two of the sides are equal, that means the 2 angles at the bottom of the triangle are both equal to 25. Since the interior angles in a triangle always add up to 180, so it would be:

25 + 25 + 4x + 2 = 180

Solving,

52 + 4x = 180

subtract 52 from both sides

[tex]4x = 128[/tex]

divide both sides by 4

[tex]x = 32[/tex]°

hope that makes sense!

Answer:

x = 32

Step-by-step explanation:

the tic marks on the two sides of the triangle indicate they are congruent; therefore the two base angles are congruent also - each is 25°.

so, we can set up this equation to solve for 'x':  25 + 25 + 4x + 2 = 180

52 + 4x = 180

4x = 128

x = 32

Answer:

y = -2.5x + 5

Step-by-step explanation:

Here, given the x and y intercept, we want to write the equation of the line

The general equation form is;

y = mx + b

where m is the slope and b is the y-intercept

Using the given points, we have that;

(2,0) and (0,5)

b is 5

so we have;

y = mx + 5

to get m, set (2,0); x = 2 and y = 0

0 = 2m + 5

2m = -5

m = -5/2 = -2.5

So the equation is;

y = -2.5x + 5

1. We need to perform a division by multiplying the dividend with the reciprocal of the divisor. We can apply this rule:

In the problem... [tex]2(x^4 +9)/x(x^2 +1)[/tex]

[tex]2(x^4 +9)/x(x^2 +1)[/tex] changes to [tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex]

2. We need to get rid of all the parenthesis in this term. [tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex]

[tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex] is now [tex]2(x^4+9)(\frac{1}{x(x^2+1)}[/tex]

3. Lastly, we need to perform a multiplication.

Therefore, the answer is:  [tex]\frac{2(x^4+9)}{x(x^2+1)}[/tex]
