7 sums

Step-by-step explanation:

The die is 1,2,3,4,5,6

Ad the card is 6 or 7

We can get

die card   sum         die card   sum

1 6              7              1 7             8

2 6               8            2 7          9

3 6               9             3 7          10

4 6               10           4 7           11  

5 6               11           5 7            12

6 6              12            6 7           13

2. Seiji and Gavin both worked hard over the summer. Together they earned a total of $425. Gavin earned $25 more than Seiji. (a)
Alja [10]
Let Gavin be G
Let Seiji be S

G + S = 425
G = 25 + S


I can't really graph, but plug in some numbers to G and S that works in BOTH equations. Then graph it.

G + S = 425
G = 25 + S

(25 + S) + S = 425
2S + 25 = 425
2S + 25 (-25) = 425 (-25)
2S = 400
2S/2 = 400/2
S = 200

Seiji made 200 dollars

Now choose one of the equations to use (the easier the better) in this case i will choose this one:

G = 25 + S

pug in 200 into S (because that is how much Seiji made)

G = 25 + (200)
G = 225

Seiji made 200, Gavin made 225

200 + 225 = 425, which is the total amount the made

hope this helps

Consider the following system of equations: 10 + y = 5x + x2 5x + y = 1 The first equation is an equation of a . The second equa
aleksley [76]

Answer: The first equation is an equation of a parabola. The second equation is an equation of a line.

Explanation:

The first equation is,

10+y=5x+x^2

In this equation the degree of y is 1 and the degree of x is 2. The degree of both variables are not same. Since the coefficients of y and higher degree of x is positive, therefore it is a graph of an upward parabola.

The second equation is,

5x+y=1

In this equation the degree of x is 1 and the degree of y is 1. The degree of both variables are same. Since both variables have same degree which is 1, therefore it is linear equation and it forms a line.

Therefore, the first equation is an equation of a parabola. The second equation is an equation of a line.

Trent is fishing from a pier.
snow_tiger [21]
To estimate the distance between the tip of his fishingrod which is above the water and the hook which is below the water, you will need to estimate the absolute values of both distances.
|53 3/4| + |12 2/3|54 + 1367 ft
Trents estimate is not reasonable because you would around both of these values up to the next whole number making it greater than 65.
