Answer:

4 = n.

13 ft.

Step-by-step explanation:

An equilateral triangle means that all of the sides are equal.

This means: 2n + 5 = 3n + 1 = 5n -7

You can pick two of those sides to set up an equation to solve for n.

For example, 2n + 5 = 3n + 1.

Then you will need to isolate the variable.

Subtract 1 from each side to get 2n + 4 = 3n.

Subtract 2n from each side to get 4 = n.

Substitue 4 for n into one of the equations.

2n + 5

2(4) + 5

8 + 5 = 13

Each side is 13 ft.

Step-by-step explanation:

4(y+3)+2(y+7) = 2(3y`=13)

6(2w+5)+9(w+2) = 3(7w+16)

3(y-2)+4(2y+5) = 11y+4

7(2g+3)-5(g+2)= 9g+11

6(x-2)-4(x-8) = 2(x+10)

2(3y-8)-5(2y-1) = -4y-11

8(5+2m) +3(5-3m) = 55+7m

4(w+7)-2(2w+1) = 26

9(1+2y)+3(3-y) = 3(6+5y)

Answer:

1.) y=4.3

2.) w=2.2

3.) y=1.2

4.)g=1.2

Answer:

Step-by-step explanation:

The general equation of a circle is expressed as;

(x-a)²+(y-b)² = r² where;

(a, b) is the centre of the circle

r is the radius

Given the centre (8, 3) and the radius of 9, the equation of the circle will be;

(x-a)²+(y-b)² = r²

(x-8)²+(y-3)² = 9²

(x-8)²+(y-3)² = 81

hence the required equation is  (x-8)²+(y-3)² = 81

First multiply 10 x 2=20

then you add 82 and 3.8 which is 85.8

then you subtract 20 from 85.8 and you get 65.8

Answer:

1/12

Step-by-step explanation:

Probability is a ratio derived as the number of possible outcomes divided by the total outcome.

On a number cube, the even sides are 2, 4 and 6. This means that the possible outcome for rolling an even is 3 while the total outcome is 6. Hence the probability of rolling an even P(E)

= 3/6

The probability of rolling a 4  P(4)

= 1/6 (4 appears on one side)

Hence  the probability of rolling an even on the first roll and a four on the second roll

P(En4) = 3/6 * 1/6

= 3/36

= 1/12

Given:

A student has $78 in his checking account.

The student spends $12 on lunch.

To find:

The number that could be combined with the amount left in the account to make zero.

Solution:

We have,

Amount in account = $78

Money spend on lunch = $12

Remaining amount = Amount in account - Money spend on lunch

                               = $78 - $12

                               = $66

Remaining amount is $66. So, -66 could be combined with the amount left in the account to make zero.

[tex]66+(-66)=66-66=0[/tex]

Therefore, the correct option is C.

Answer:

the length would be 410.15m

Step-by-step explanation:

The computation of the length is as follows;

Length = 340m

Let us assume x be train length

Now

the distance traveled by the train is  (L + x)

d = L + x

v = 60 km ÷ h

= 16.67 m / s

And,

t = (3 ÷ 4) (60)

= 45s

Now

d = vt

L + x = (16,67) (45)

x = (16,67) (45) - 340m

x = 410.15m

Hence, the length would be 410.15m

Answer:

300

Step-by-step explanation:

Day 1: $70

Day 2: $80

Total commission = day 1 × 2 + day 2 × 2

= 70 × 2 + 80×2

= 140 + 160

= 300

Or

Total commission = 2(day 1 + days 2)

= 2(70 + 80)

= 2(150)

x = 300

120 cubic ft is the volume of  rectangular prism having a length of 10ft, a height of 3ft, and a width of 4ft

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

A rectangular prism is a 3D figure with 6 rectangular faces.

Given, rectangular prism has a length of 10ft, a height of 3ft, and a width of 4ft.

To find the volume of rectangular prism we have to multiply length, width and height.

Volume =Length×Width×Height

Put the values of length, width and height in the above formula.

=10×4×3

=120 cubic ft

Hence 120 cubic ft is the volume of  rectangular prism having a length of 10ft, a height of 3ft, and a width of 4ft

Answer:

The answer to the first one is y=3/2x-27/2

The answer to the second one is y=-3/5x+6/5

Step-by-step explanation:

1. 2y-3x=-27

first, you want to add '3x' to both sides.

2y=3x-27

then you want to divide '2' from both sides. you do not want to use the 'y' because you want to keep the 'y' on its own side.

y=3/2x-27/2

2. 5y+3x=6

First, you want to subtract '3x' from both sides.

5y=-3x+6

Now, you want to divide '5' from both sides.

y=-3/5x+6/5
