Answers

Answer 1
Answer: Hello, 

14z - 27z = - 13z 

Have a nice day
Answer 2
Answer: D. -13z is the correct answer...since both values have z the you can simply subtract 27 from 14. Hope this helps and, if you are able to do so, please mark Brainliest!

In the fraction 5/8 what is the term used to designate the 5?

Answers

in a fraction, when we write the fraction like this:

the top one is called "numerator" and the bottom one "denominator"

like this:
 
(numerator)/(denominator)

so 5 here is the numerator!

Sharon is 54 inches tall. tree in her backyard is five times as tall as she is. the floor of her treehouse is at a height that is twice as tall as she is. What is the difference in inches between the top of the tree and the floor of the treehouse?

Answers

First to solve this problem you are going to figure out how tall the tree is. So if Sharon is 54 inches and the tree 5 times the height she is you would do 54*5= 270. Next you go to find out how tall the floor of her tree house is. It says the floor is twice the height of her so you would do 54*2=108. Then the problem asks the difference between the top of the tree and the floor of the tree house. So 270-108=162. I hope this helped. :) Brainliest answer?

Identify the triangle ratio used and then use it to solve for the missing information (Round answer to 2 decimal places)

Answers

Answer: 24 cm

Step-by-step explanation:

33 + 23 + x= 180

56 + x = 180

56-56 +x = 180-56

x = 24 cm

Mustafa buys seed packets for a community garden. One packet of basil seeds costs $1.50. One packet of squash seeds costs $2.50. Let b represent the number of packets of basil seed. Let s represent the number of packets of squash seeds. Mustafa spent $38 on 18 packets of seeds. How many packets of each type of seeds did Mustafa buy?

Answers

There are total 11 packets of squash seeds and 7 packets of basil seeds.

What is system of linear equations?

A system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.

What is substitution method?

The substitution method is the algebraic method to solve simultaneous linear equations. In this method, the value of one variable from one equation is substituted in the other equation.

According to the given question.

Cost of one packet of basil seeds = $1.50

Cost of one packet of squash seeds = $2.50

Cost of 18 packets of seeds = 38

Also, b represents the number of packets of basil seeds and s represents of numbers of squash seeds.

Therefore, from the given conditions we get some system of equations

s + b = 18..(i)

and b(1.50) + s(2.50) = 38...(ii)

From equation (i)

s = 18-b

Substitute the value of s in the equation (ii)

⇒1.50b+(18-b)2.50 =38

⇒ 1.50b + 45 - 2.50b = 38

⇒-b = 38-45

⇒ -1b =- 7

⇒b = 7

So, s = 18 - 7 =11

Hence, there are total 11 packets of squash seeds and 7 packets of basil seeds.

#SPJ2

Answer:

Step-by-step explanation:

b+s=18

s=18-b

1.50 b+2.50 s=38

multiply by 4

6.00 b+10.00 s=152

divide by 2

3 b+5 s=76

3 b+5(18-b)=76

3 b+90-5 b=76

-2b=76-90

-2b=-14

divide by -2

b=7

s=18-7=11

okay so my homework says the measures of two angles of a triangle are given.Find the measure of the third angle please help??????!!!!!!!!!!

Answers

 
Do you remember hearing that the angles of every triangle in the world
all add up to the same number ?  They always add up to 180 degrees.

If you know the measures of two of the angles, then just take those away
(subtract) from 180 degrees, and whatever you have left must be the last angle.

For example, let's take the last one on your list:

54 and 36 are given.

       180 minus 54 = 126
then
       126 minus 36 = 90 . . ==> the missing angle is 90 degrees
===================================================
Another way to do it:  One addition and one subtraction.

(54 + 36) = 90      That's the total amount you have to take away from 180.

180 minus 90 = 90  <== that's the missing angle.
