Gerald deposits $50 every week into a savings account. At week 16, the account balance is $1650. Write an equation that models the balance, y, and the number of weeks, x.

Answers

50y and 16x would be the answer because yeah
I think y=50x+850
Becauseee y is the balance and x is the weeks so if we plug in the information we’re given about the balance being 1650 at 16 weeks, it’d be
1650=50(16)+850
Which if you do the math it’s 1650=1650

Line M is represented by the following equation: x − y = 8

Which equation completes the system that is satisfied by the solution (18, 10)? (4 points)

a
2x − y = 26

b
x + y = 18

c
2x − 2y = 36

d
x − y = −28

Answers

Answer:Let's plug in (18,10) into each answer choice until we find the one that has it as a solution.

A) 2x - y = 26

2(18) - 10 = 26

36 - 10 = 26

26 = 26

Your answer is A.

I'll just do the rest to show that you the they are incorrect.

B) x + y = 18

18 + 10 = 18

28 ≠ 18

C) 2x - 2y = 36

2(18) - 2(10) = 36

36 - 20 = 36

16 ≠ 36

D) x - y = -28

18 - 10 = -28

8 ≠ -28

Your answer is A) 2x - y = 26.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

2(18) - (10) = 26

The solution to this system of linear equations will be (–1, 3). Then the correct option is D.

What is the solution of the equation?

The solution of the equation means the value of the unknown or variable.

The equations are given below.

 y − 4x = 7   ...1

2y + 4x = 2  ...2

Add both equations, then we have

3y = 9

 y = 3

Put y = 3 in equation 1, then we have

3 − 4x = 7

     4x = –4

       x = –1

The solution to this system of linear equations will be (–1, 3).

Then the correct option is D.

how do i solve for c 0.2(c - 3)= -10

Answers

Answer: c = -47

Step-by-step explanation:

1. Divide both sides

2. Move the constant to the right

3. Calculate

Answer:

c = -47

Step-by-step explanation:

Here's how!

0.2(c - 3) = -10 (distribute 0.2 to c and -3)

0.2c - 0.6 = -10 (add 0.6 to both sides)

0.2c = -9.4 (divide by 0.2 on both sides)

c = -47

Plug in

0.2(-47 - 3) = -10 (add -47 and -3)

0.2(-50) = -10 (distribute)

-10 = -10

Each week mrs endo bikes 0.86 mile to the garden. Then she bikes 2.3 miles along the river back home. About how many miles will mrs endo bike in a year?

Answers

Answer: 164.32 miles

Step-by-step explanation:

Given that:

Weekly coverage :

Miles biked to the river = 0.86 miles

Miles biked along the river back home =. 2.3 miles

Total miles biked weekly:

(0.86 + 2.3) miles = 3.16 miles weekly

Number of weeks per year = 52

Miles biked yearly : (number of weeks per year * miles biked weekly)

= 52 * 3.16 miles

= 164.32 miles

Mrs endo will bike about 164.32 miles in a year.

Yolanda has a 1/6 -cup ladle that she uses to pour gravy over potatoes. She uses one full ladle for each serving of potatoes. Yolanda has 6 cups of gravy. How many servings of potatoes can she make?

Answers

Answer: For 6 cups of gravy, Yolanda will have 36 servings of potatoes

Step-by-step explanation:

Step 1

Since  Yolanda has a  1/6-cup of ladle for one full serving

Then for every serving the 1/6- cup ladle  is used and can be expressed as

1 serving  =1/6-cup of ladle

Step 2--- Solving

Serving of potatoes for  1 cup is

1 serving  =1/6 cup of ladle

?? servings=1 cup of ladle ( cross multiply)

=  1 x 6/1 =  6 servings

Therefore  6 cups of gravy =  6 servings x 6 = 36 servings of potatoes

The 7th grade students at Palm Coast Middle School made some apple pies for a bake sale. The school cafeteria also donated 9 pies toward the effort. All the pies at the sale were cut into 8 pieces. If at least 224 pieces of pie were sold in all, how many pies did the students bake? (shown on number lines)

Answers

Answer: at least 19

Step-by-step explanation:

Since there were at least 224 pieces of pie sold. We would divide the amount of slices of pie sold (224) by the amount of slices in each pie (8). Which would be (28) pies sold and then we would subtract the (9) pies that the school gave us, and we would end up with (19) pies.

She was an adventurous and fun-loving child. That adventurous spirit remained as she grew older. One day in 1920, after going on a plane ride, she was determined to fly planes. She worked at any job she could find to save up for flying lessons, which cost $1,000. At one point, she worked as a nurses aid and a social worker. Six months after receiving flying lessons, Amelia bought her own plane, and she flew as high as 14,000 feet, which set a world record for female pilots. A short time afterward, Amelia became the sixteenth female to earn a pilots license. In 1928, an opportunity arose for Amelia to participate in a transatlantic flight across the Atlantic Ocean as a copilot. This experience later came in handy when she became the first woman to fly solo across the Atlantic in 1938. She received many honors for this achievement, such as the Distinguished Flying Cross from Congress.As Amelia approached her fortieth birthday, she was planning her biggest trip yet: She wanted to be the first woman to fly around the world. Of course, she needed a lot of help to make this happen. She made a first attempt that failed and damaged her plane. But Earhart was not one to give up, so she made another attempt at the ground-breaking mission. She did make some progress by flying 7,000 miles to New Guinea but did not make it to her next stop, Howland Island. Sadly, Earharts plane disappeared, and, despite search and rescue attempts, she was never found. To this day, Earhart is known and celebrated for her bravery, persistence, and commitment to aviation.Which sentence from the passage contains information that could best be used to create a yearbook blurb about Amelia Earhart?As Amelia approached her fortieth birthday, she was planning her biggest trip yet.
