Find an equivalent expression for -3(2x+5)-(x-1)

Answers

Answer:

-7x - 14

Step-by-step explanation:

By simplifying the expression:

-3(2x+5) - (x - 1)

-6x-15 -x + 1

-7x - 14

Answer:

-7x - 14

Step-by-step explanation:

You can use the distributive property to find an equivalent expression.

Distribute -3 to 2x + 5.

(-3 × 2x) + (-3 × 5) = -6x + (-15) = -6x - 15

Distribute -1 to x - 1. (It is -1 because there is always a 1 in front of things like x = 1x and (x + 1) = 1(x + 1). 1 times anything equals the number it is multiplied by. There is a - sign in front of the parenthesis, which makes the invisible 1 a -1.)

(-1 × x) + (-1 × -1) = -x + 1

You can simplify the expression.

(-6x - 15) + (-x + 1) = -7x - 15 + 1 = -7x - 14

A drawer contains 5 red socks, 9 white socks, and 6 blue socks. Without looking, you draw out a sock and then draw out a second sock without returning the first sock.
Find P(blue, then blue).
Your answer:

Answers

P = Number of favourable outcomes ÷ Sum of total outcomes

So, Probability of drawing a blue sock is

Number of blue socks ÷ Number of total socks

= 6 ÷ 20

= 3 ÷ 10

= 0.3

Now as we have drawn a sock already the total number of socks in the drawer are 19

So, the probability of drawing a blue sock now will be :

= 6 ÷ 19

= 0.31

Answers

Answer:

12,000, 900, 210, 18       4376x3=13128

Step-by-step explanation:

In the 1st box, you put the product of 4,000 x 3 = 12,000

In the 2nd, you put the product of 300 x 3 = 900

In the 3rd, you put the product of 70 x 3 = 210

In the 4th, you put the product of 6 x 3 = 18

Then you add your answers

12,000 + 900 + 210 + 18 = 13,128

The required partial product of 4376 × 3 is 13128.

What is the partial product?

In mathematics, partial products are defined as multiplying each digit of one integer by each digit of another number while keeping each digit's place value.

Here,
4376 × 3 = [4000 + 300 + 70 + 6] × 3

Simplifying using the distribution of 3,
= 4000 × 3 + 300 × 3 + 70 × 3 + 6 × 3
= 12000 + 900 + 210 + 18
= 13128

Thus, the required partial product of 4376 × 3 is 13128.

If each box (from slide 4) used material that cost $0.03 per square inch to make, how much does a company save by choosing to make fifty boxes of the smaller box in comparison to fifty boxes of the larger box?

Answers

Answer:

1st box: 385 in squared x .03 = $11.55 per box.

$11.55 x 50 boxes = $577.50

2nd box: 439.75 in squared x .03 = $13.1925

$13.1925 x 50 boxes = about $659.63

The company would save $659.63 - $577.50= $82.13 per 50 boxes if they go with the smaller box.

If a square has an area of 100ft², what is the length of one of the sides.

Answers

Answer:

The length of one side is 10 feet

Step-by-step explanation:

This is because the area of a square can be found through the formula side x side or [tex]side^{2}[/tex]. You can find the length of one side by finding the square root of the area. You would get both a positive and negative value for the square root but you want a positive value because a length cannot be negative.

I buy a bed which normally costs £270 on a scheme where the price of the bed is increased by 60% but I only pay back £18 a month.
How long will it take to fully purchase the bed?

Answers

Answer:

it would take 2 years or 24 months

Step-by-step explanation:

60 percent of 270 is 162 add that to 270 and you get 432 divide that by 18 because that's what you're paying every month and you get 24 which is the numbe rof months it will take you to pay the bed off.

To cross check we can multiply 18 and 24 and you get 432.

Answer:

=432

Step-by-step explanation:

270-60%=162

162+270=432

432÷18=24

24×18=432

The area of the actual floor is ................... square feet.
The ratio of the area in the drawing to the actual area is 1 square centimeter:............. square ft

Answers

Answer: Ok let's say the area is 100 sq cm because it is 10x10 square. Now if 1 cm is 2 ft then 10 cm is 20 ft. So 20 x 20 is 400 sq ft which is the actual area.

It can grow as high as 75 feet tall. The fall season brings shorter days and cooler temperatures. Fall also brings changes to the leaves of the northern red oak. Leaves turn from green to shades of yellow, orange, and red, which is an amazing sight. It makes the northern red oak an eye-catching stand out among other trees in the oak family.In summer, the gray rough branches of the northern red oak grow long and wide. This is the season when branches can become overly long and heavy. The weight of the branches' leaves adds even more pounds. If the growth of the tree is not managed, the entire appearance of the tree can be changed. Early trimming helps groom the tree and keeps it from looking like a rounded triangle by summer's end.Both the size and the shape of the northern red oak's leaves are especially interesting. It is easy to find leaves that are larger than a man's hand. They often have 8 or more pointed fingers. That makes northern red oak leaves look like large, flattened evergreen trees.Residents in the Midwest especially enjoy the beauty of their northern red oaks in October. A common sight is to see people walking or relaxing under them. They gaze up, watching the colored leaves dance in the cool fall breeze, knowing that winter will soon come to take the leaves away.Second Passage: The Hardy Live OakThe live oak tree is one of the toughest trees found in the United States. It is not a tall tree. It grows only 30 to 40 feet high. But its branches are broad and strong. The branches make up for the tree's rather short height. How? The branches stretch out from the trunk like thick arms on a giant. The leaves on the branches are simple. They are oval in shape. They glisten in the sun. Most importantly, live oak leaves are always there. Live oaks stay green all year round.The live oak is also a fast growing tree. It is often planted in the lawns of new houses. This lets people living in the house have shade in just a few years. However, the owner of the tree needs to keep the lower branches trimmed. If the lower branches are not trimmed, over time the lower tree limbs will grow downward toward the ground. These branches will seem to almost slither like a snake. In time, they will be only inches above the ground. They will also spread out over the lawn for up to 25 feet from the trunk of the tree.The live oak tree is popular for a very important reason. It can live in very hot weather. Strong sunlight does not kill it. People in the southern United States see so many live oaks that they no longer really notice them. Live oak trees just blend into the landscape. Yet, live oaks contribute to the landscape in many ways. They provide shade in the summer heat. They also provide food for many animals. Each live oak tree can produce thousands of acorns. Squirrels are just one type of animal that scurries to feast on the little brown nuts. Live oaks are certainly a treasure in hot places with harsh sunny weather. Solve all this1) 2x-8=11x-102)6x-6=3x+13)1/2x+4=1/3x+14)-2/5x+1/3=1/2x+1/45)5/3x2=1/2x-2/3 Sharon is buying candy.
