Answer:

First number = 25

Second number  = 14

Step-by-step explanation:

Let the numbers be x & y

The sum of twice the first and thrice the second is 92

2x + 3y = 92   -------------------(I)

Four times the first exceeds seven times the second by 2​

4x - 7y = 2  --------------------(II)

Multiply  equation (I) by -2 and then add the equations

(I)*-2          -4x - 6y = -184

(II)               4x - 7y = 2      { Now add, thus x will be eliminated}

                      - 13y = -182 {Divide both sides by -13}

y = -182/-13

y = 14

Plugin the value of y in equation (I)

2x + 3*14 = 92

2x + 42 = 92

       2x = 92 - 42

       2x = 50

        x  = 50/2

x = 25

First number = 25

Second number  = 14

Answer:

option 4

Step-by-step explanation:

-3.4x + 4.7 - (3 + 2.9x) = -3.4x + 4.7 - 3  - 2.9x  (combine like terms)

                                   = -3.4x - 2.9x + 4.7 - 3

                                  = - 6.3x + 1.7

If two number have same sign, add and put the common sign for the answer.

If two numbers have different sign, subtract and the answer will have the sign of the bigger number

Answer: D also, can i have brainliest?

solution:

The other 2 sides added have to be greater than 13

Option A: 5 + 8 = 13. 13 is not greater than 13 so it's not the answer.

B: 6 + 7 = 13. Same thing as option A

C: 7 + 2 = 9. 9 is less than 13 so not the answer.

D: 8 + 8 = 16. 16 is greater than 13 so D is the correct answer.

Answer:

4y = -7-2x

y = -7-2x/4

now give suitable value for x (Example 3)

Answer:

[tex]y=-\frac{1}{2} x-\frac{7}{4}[/tex]

Step-by-step explanation:

[tex]4y+2x=-7[/tex]

Subtract [tex]2x[/tex] from both sides of the equation.

[tex]4y+2x-2x=-7-2x[/tex]

[tex]4y=-7-2x[/tex]

Divide by 4 on both sides of the equation.

[tex]\frac{4y}{4} =\frac{-7-2x}{4}[/tex]

[tex]y=\frac{-2x-7}{4}[/tex]

Simplify the equation.

[tex]y=-\frac{1}{2} x-\frac{7}{4}[/tex]

Answer:

A

Step-by-step explanation:

we know that the plot decreases from left to right so the slope is negative. that eliminates choices b and d. we also know that they y-intercept is between 5 and 8. that eliminates c.

Answer:

Step 1

Step-by-step explanation:

I believe it's step 1 because he subtracted 6 from 86 before distributing the five. In math, you must follow PEMDAS (parentheses, exponents, multiplication & division, addition & subtraction.) This person skipped the parentheses.

Solution,

4(2n-3)

=4*2n-4*3

=8n-12

Answer:

3.6 and 2

Step-by-step explanation:

Given R is inversely proportional to A then the equation relating them is

R = [tex]\frac{k}{A}[/tex] ← k is the constant of proportion

To find k use the condition R = 12 when A = 1.5, that is

12 = [tex]\frac{k}{1.5}[/tex] ( multiply both sides by 1.5 )

18 = k

R = [tex]\frac{18}{A}[/tex] ← equation of proportion

(a)

when A = 5, then

R = [tex]\frac{18}{5}[/tex] = 3.6

(b)

when R = 9, then

9 = [tex]\frac{18}{A}[/tex] ( multiply both sides by A )

9A = 18 ( divide both sides by 9 )

A = 2

Answer:

$2090

Step-by-step explanation:

The time is 6/12 since it is in months and not years

Interest = [tex]\frac{Principal * Rate * Time}{1}[/tex]

              =[tex]\frac{2000 * 9 * 6}{100*12}[/tex]

              = $90

This means her balance will be $(2000+ 90) = $2090

Answer:

Step-by-step explanation:

by making the length an inequality x height will be 1.5x

Volume=1/3BA xh

X×X×1.5X 1/3=2304

0.5x3=2304

X³=2304÷0.5

X³=4608

X=³√4608

X=16.64cm

H=16.64x1.5=24.96cm

The height of the square pyramid is equal to 24.96 cm.

A square pyramid in geometry is a pyramid with a square base. A right square pyramid is one in which the peak is perpendicular to and above the square's centre.

Given that the height of a square pyramid is one-half the length of each side. The volume of the pyramid is 2,304 cubic inches.

The height of the square pyramid will be calculated as,

Volume=1/3BA xh

X×X×1.5X 1/3=2304

0.5x3=2304

X³=2304÷0.5

X³=4608

X=³√4608

X=16.64cm

H=16.64x1.5=24.96 cm

Therefore, the height of the square pyramid is equal to 24.96 cm.

Answer:

10

Step-by-step explanation:

Align the data from smallest to largest

3,8,9, 11, 14,  15*

The median is the middle number

3,8,9,     11, 14,  15*

It would be between the 9 and 11 since there is an even number of numbers

(9+11)/2 = 20/2 = 10

The median is 10

Solution:

Arranging the data in ascending order:

3,8,9,11,14,15

N(total number of items)=6

Median=(N+1/2) th item

=(6+1/2)th item

=(7/2)th item

=3.5th item.

Median=3rd item+4th item/2

=9+11/2

= 20/2

=10

Median =10

Answer:

6 teaspoons

Step-by-step explanation:

2 teaspoons = 1/3 tsp of salt

6 teaspoons = 1 tsp of salt

This was done by multiplying 2 by 3 since 3 thirds (3/3) make one whole.

So if 2 teaspoons are used for 1/3 teaspoon of salt, 4 teaspoons would be used for 2/3 teaspoon of salt and 6 teaspoons would be used for 1 teaspoon of salt.
