Mrs. Pena is buying 3 kinds of sandwiches for a family reunion. She buys x egg salad sandwiches at $3.10 each. She buys
y corned beef sandwiches at $3.35 each. Finally, she buys z cheese sandwiches at $2.85 each. Mrs. Pena spent a total of
$148.55 on the sandwiches. Which equation could be used to represent the situation?
A 3.10x + 3.35y + 2.85z = 148.55
00
(3.10 + 3.35 + 2.85)xyz = 148.55
(x + y + 2)(3.10 + 3.35 + 2.85) = 148.55
D
x + y + z = 148.55

Answer:

y+7 = 1/7(x+3)

Step-by-step explanation:

Point slope form of a line is given by

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is a point on the line

(y -  -7) = 1/7(x - -3)

y+7 = 1/7(x+3)

Answer:

Increased by 37.5%

Step-by-step explanation:

1. Approach

First, find the amount by which the bill increased. This can be found by subtracting the final amount from the previous amount. Then set up a proportion to find out the percent by which the bill increased. Remember, a proportion is;

[tex]\frac{part}{whole} = \frac{percent}{100}[/tex]

2. Find the increase

Subtract the bill in March from the bill in June;

June - March

110 - 80

= 30

3. Find the percent change

In this case, these are the value which will be used;

[tex]\frac{increase}{March} = \frac{percent}{100}[/tex]

[tex]\frac{30}{80} = \frac{percent}{100}[/tex]

80 percent = 3000

percent = 37.5

Answer:

n = 17

Step-by-step explanation:

+(-6) is the same thing as n - 6 = 11 to take out the + sign in order to avoid confusion.  Add 6 on both sides to get your n value which is 17.

Answer:

Step-by-step explanation:

here you go mate

step 1

n +-6 = 11  equation/Question

step 2

n +-6 = 11  add 6 to each side

Answer:

In this item, we are given that out of 12 ounces of ingredients comprising the milkshake, there are 4 ounces vanilla. Expressing this into fraction will give us an answer of 4/12. This fraction can be one of the answers. Since we are asked for two fractions, we can simplify 4/12 such that we get an equivalent fraction that is equal to 2/6. Hence, the answers to this question are 4/12 and 2/6.

Answer:

The equation of a line is y = ax + b, where a is the slope and b is the y-intercept.  

Since we have the y-intercept, all we need to do is find the slope. To find the slope, you need 2 coordinates.

The y-intercept is where the line crosses the y axis, so it is where x is 0. Since the y intercept is -2, that means the first coordinate is (0, -2)

The x-intercept is where the line crosses the x axis, so it is where y is 0. Since the x intercept is 4, that means the second coordinate is (4, 0)

Since we already have the y-intercept, all we do is put the slope in the equation: y = 1/2x - 2.

Step-by-step explanation:

Answer: A

3/4 equals 6/8 and 9/12 and 12/16

y=-x+4 is the Equation of the Line Passes through the points (-4,8) and (1,3).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The slope of line passing through points (-4,8) and (1,3)

m=3-8/1+4

=-5/5=-1

Now we need to find the y intercept

8=-1(-4)+b

8=4+b

b=4

Hence, y=-x+4 is the Equation of the Line Passes through the points (-4,8) and (1,3).
