What property justifies 4x=7

Answer:

He gained more than 50 yards in the game.

Step-by-step explanation:

Running back in the first quarter in a football game = -8.5 yards

Running back in second quarter = 23 yards

Running back in 3rd quarter = 42.5 yards

Running back in 4th quarter = -2.25 yards

Total gain in the game = -8.5 + 23 + 42.5 - 2.25 = 54.75 yards

That means he gained more than 50 yards in the game.

Answer:

B. To add a list of numbers in a spreadsheet

Step-by-step explanation:

AutoSum feature in Microsoft Excel is used to automatically sum up a range of numbers within a horizontal row or vertical column without having to input a formula.

When a range of numbers are selected within a row or column, clicking on AutoSum will sum up the numbers in the adjacent empty cell. For example, if you wanted to add the values of cells between B1 and B10, highlight cells B1 through B10 and click the AutoSum button . The sum of B1 to B10 will be given in B11.

In Excel 2010 and later, the AutoSum feature is on the Home tab, in the Editing section.

Answer:

The graph is being stretched vertically, so it will be thinner.

Step-by-step explanation:

g(x) = 8f(x) means that you are multiplying each original y-value by 8, so the graph gets thinner. When there's a number n greater than 1 in front of the function, it's a vertical stretch by n.

Answer: 1/2(x+12)

Step-by-step explanation:

Answer:

×=11/4

Step-by-step explanation:

0=-2x+6x-11

0=4x-11

-4x=-11

x=11/4

Answer n=6

Step-by-step explanation:

Given that, the cost of a ticket = t and

cost of a box of popcorn =  p.

Total members in the team = 13

As each team member buys 1 ticket and 2  boxes of popcorn, so, the amount spent by one member, [tex]C_1 = t+2p[/tex]

So, the total amount that the team spent [tex]= 13C_1[/tex]

(a) So, the first expression, representing the total amount spent by the team, is

[tex]13\times (t+2p)\cdots(i)[/tex]

On simplification, the second expression, representing the total amount spent by the team, is

[tex]13\timest + 13\times (2p)[/tex]

[tex]=13t+26p\cdots(ii)[/tex]

(b) The expression from the equation (i) represent the total amount spent as 13 times the expenses of one member, while equation (ii) is the sum of two terms where the first term, 13t, represents the total amount spent for buying the ticket and the second term, 26p, represents the total amount spent for buying popcorn

Answer:

24.99

Step-by-step explanation:

Answer:

The equation is y = -2x + 6.

Step-by-step explanation:

Given that the slope-form equation is y = mx + b and the gradient is -2. So you have to find the value of b by substituting the coordinates into the equation :

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

[tex]let \: m = - 2,x = 4,y = - 2[/tex]

[tex] - 2 = - 2(4) + b[/tex]

[tex] - 2 = - 8 + b[/tex]

[tex]b = 6[/tex]

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

x = -20

Step-by-step explanation:

just divide -4 into both sides

Answer:

the formula for the area of a triangle is a= b*h/2

Step-by-step explanation:

area= base* height divided by two.

if a triangles base was 5 height was 4 the area would be 10units

5*4=20

20/2=10

I used a random example as the specific example was not listed in the question.

Answer:

SR is 17, using the side, angle, side rule of congruency.

Step-by-step explanation:

Triangle SRV is congruent to triangle STV, so SR would be equal to ST, which is 17. Since SV creates a right angle when it bisects RT, we know the they both share a right angle. We also know that the the side created by SV is the same for both. Since they told us that RV equals VT, we know that the triangles are congruent by the SAS (side angle side) rule. Hope this helps!

Answer: 3ad^3

Step-by-step explanation: they have the same terms

Answer:

b is 90, d is 46, and the bottom two are twenty

Step-by-step explanation:

on the top two the oppisite is the answer so if c=90 then so does b and along with d

each line is 180 and the top and bottom are the same angles along with the two sides so if you subtract 180 from 160 then you get 20

Read the note harder

Answer:

Since the exponent of the scientific notation is negative, move the decimal point 7 places to the left.

0.000000399

Hope this helps!

Answer:

0.000000399

Since 10 is to the power of -7 you count 7 spaces behind the decimal and then you get 0.000000399.

Answer:

-8/6

Step-by-step explanation:

To solve this you subtract y2-y1 and x2-x1. Then you divide these numbers. -3-5=-8. 2--4=6. This makes the answer -8/6.

Answer:

1,414
