Answer:

1st answer is 6, 2nd is 5, 3rd is 5

Step-by-step explanation:

3x-2=x+10

3x-x=10+2

2x=12

x=12÷2

x=6

x+4=19-2x

x+2x=19-4

3x=15

x=15÷3

x=5

8z-20=z+15

8z-z=15+20

7z=35

z=35÷7

z=5

plzz mark me as brainliest

Answer:

3x-2=x+10

x=6

x+4=19-2x

x=5

8z-20=z+15

z=5

Step-by-step explanation:

3x-2=x+10

+2 on both sides

3x-2(+2)=x+10(+2)  =>  3x=x+12

subtract x on both sides

3x(-x)=x(-x)+12   =>  2x=12

divide 2 on both sides

2x/2=12/2

= x=6

x+4=19-2x

subtract 4 on both sides

x+4(-4)=19(-4)-2x    =>    x=15-2x

add 2x on both sides    

x(+2x)=15-2x(+2x)     =>    3x=15

divide 3 on both sides

3x/3=15/3

= x=5

8z-20=z+15

subtract z on both sides

8z(-z)-20=z(-z)+15    =>  7z-20=15

add 20 on both sides

7z-20(+20)=15(+20)

7z=35

divide 7 on both sides

7z/7=35/7

= z=5

Step-by-step explanation:

by dojng lenght into breadth

Answer:

55 degrees

Step-by-step explanation:

Complementary angles are two angles that equal 90 degrees together so if one angle is 35 degrees then the other must be able to add towards that to make 90 degrees

90=35+∠2

-35     -35

55=∠2

Answer:

2/3

Step-by-step explanation:

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?

1 decametre = 10 metres

Hence,

10 meters = 6 pieces of ribbon

1 meter = x pieces

Cross Multiply

10x = 6

x = 6/10

x = 2/3 (1 meter pieces of ribbon)

Answer: 5 lattes

Step-by-step explanation: Our equation is 20 − 3.5x = 2.5, which means x = 5 lattes.

Answer:

Step-by-step explanation:

y=3.5x (cost function where y is cost and x is the number of lattes)

20-2.5=3.5x

17.5=3.5x

5=x

So she bought 5 lattes.

Answer:

b and d

Step-by-step explanation:

Answer:

[tex]\sqrt{8x^{2} }[/tex]+5-3 = 8.12

8.12 rounded to nears whole number is 8

therefore 8.12 rounded down to three decimal places is 8.1

Therefore your answer would be 8.1

If it wont let you add a decimal your answer would also be 8

3

Step-by-step explanation:

The dot is called a decimal point. It is also called the decimal separator. It separates whole numbers from fractional numbers.

In this example;

24.671

The numbers before the point, 24 is the whole number

The numbers after the point, 671 are the fractional portion of the number. They represent 6 tenths, 7 hundredths and 1 thousandths.

Also, the number of digits after the point tells you how many decimal place the number is in. In this example the number of decimal places is 3.

Answer: B. Megan can divide the number 24 by 3 and then multiply the result by 2 to find the number of striped bows.

C. Megan can multiply the number 24 by 2 and then divide the result by 3 to find the number of striped bows.

F The number of striped bows in the package is 16.

Step-by-step explanation:

Here's the options:

A. Megan can divide the number 3 by 24 and then multiply the result by 2 to find the number of striped bows.

B. Megan can divide the number 24 by 3 and then multiply the result by 2 to find the number of striped bows.

C. Megan can multiply the number 24 by 2 and then divide the result by 3 to find the number of striped bows.

D. Megan can multiply the number 24 by 3 and then divide the result by 2 to find the number of striped bows.

E The number of striped bows in the package is 36.

F The number of striped bows in the package is 16.

The number of bows in the package that are striped will be calculated as:

= 2/3 × 24

= 16

Based on the options given, the correct answers will be:

B. Megan can divide the number 24 by 3 and then multiply the result by 2 to find the number of striped bows.

C. Megan can multiply the number 24 by 2 and then divide the result by 3 to find the number of striped bows.

F The number of striped bows in the package is 16.

The correct options are B, C and F.

Complete Question

Mis. Jackson wants to rent a van for a week it will cost a weekly fee plus 0.20 per mile driven let m equal the number of miles Ms. Jackson drives during the week write an algebraic expression that shows a week rent Jackson will pay for the van for the week

Answer:

A = w + 0.20m

Step-by-step explanation:

Step 1

We find the equation for the total amount spent in a week

The total amount to rent the van in a week = A

Weekly fee = w

Number of miles = m

Therefore, thw algebraic expression that shows a week rent Jackson will pay for the van for the week is

A = w + 0.20m
