Mary has 400 slices of pizza. She gives 30 to Cambri,96 to Maria,99 to Falli,43 to Sam and 32 to Callin. How many slices does she have left?

Answers

Answer:

The answer to your problem is, 100 slices.

Step-by-step explanation:

First lets add up all the numbers that she gives away

30+96+99+43+32 =

300.

If she gave out 300 slices of pizza then here left over is:

400 - 300 = 100.

Thus the answer to our problem is, 100 slices.

Mary has 100 slices left over because if you add all the slices she gave away then subtract from the starting amount would come out to 100


30+96+99+43+32=300

400-300=100

Answer:

x = 55°

Step-by-step explanation:

The angles are complementary.  That means that they add to 90.

x + x - 20 = 90  Combine like terms

2x - 20 = 90  Add 20 to both sides

2x - 20 + 20 = 90 + 20

2x = 110  Divide both sides by 2

x = 55

Helping in the name of Jesus.

Answer:

x = 55 degrees; the angles are complementary

Step-by-step explanation:

First of all, the angles are complementary. I say this because complementary angles add up to 90 degrees and the square symbol identifies the angle as being a 90-degree angle.

Next, you add [tex]x-20+x[/tex] and set it equal to 90. With some quick addition and some properties of equality, you get the answer of 55 degrees.

A boat travels at constant speed. After 20 minutes the boat had traveled 2.5 miles. How long does it take the boat to reach the bridge which is 15 miles away?

Answers

Answer:120 minutes

Step by step:

you have to divide 20 by 2.5 to find how many minutes it takes to drive 1 mile. lastly, multiply that by 15 miles

20 divided by 2.5

1 hour - 60 mins
20mins - 2.5 miles
2.5 • 3= 7.5 miles in 1hr
7.5+7.5=15 miles in 2hrs
answer: it takes 120 minutes or 2 hours to reach the bridge

2 birds had 14 babies. The mom kept having babies for the next 43 years. How many babies did she have

Answers

Answer:

14x43=602 babies

Step-by-step explanation:

Is this the whole context of the problem? Going off of the idea that 14 babies are born every year each year the amount of birds would increase by 14. For example after two years (14x2) there would be 28 birds then after three years (14x3) there would be 42 so on so forth.

602 because 14 times 43 equals 602 since she keeps have babies for the next 43 years

Answers

Answer:

B. 335.5 in.²

Step-by-step explanation:

The pencil decoration can be broken down into a rectangle and a triangle.

The area of the pencil decoration is the sum of the areas of the rectangle and triangle.

The rectangle has length b and width a.

The triangle has base a and height a.

total area = area of rectangle + area of triangle

total area = length × width + base × height / 2

total area = b × a + a × a / 2

From the given information, we see that a = 11 in., and b = 25 in.

total area = b × a + a × a / 2

total area = (25 in.) × (11 in.) + (11 in.) × (11 in.) / 2

total area = 275 in.² + 60.5 in.²

total area = 335.5 in.²

The answer is B 335.5 in

I would love an explanation to help me understand how to solve the other problems like this one

Answers

I think is B but I’m not sure

it is A. 0.25x - 6.50

You use distributed property first so the equation will be 3x - 1 - 2.75x - 5.50

Then you combine like terms so 3x - 2.75 will equal 0.25x

The subtraction symbol will stick with 1 making it -1 so the second part will be -1 - 5.50 will equal 6.50

And finally, the expression will be 0.25x - 6.50

How do I graph y = -1 = 2x and y = -4 + 2x?

Answers

Answer:

Slope = Rise/Run

To graph, you first need the y-intercept.

In y = -1 + 2x, the y-intercept is -1. Start in -1 and then go two units up, and 1 unit to the right which will represent the slops, 2.

In y = -4 + 2x, the y-intercept is -4, so you'll start at -4, then go 2 u its up, and 1 to the right which will represent the slope, 2.

To find y-intercept:

y = mx + b            |      main things:      m = slope       b = y-intercept
