ILL GIVE BRAINLIEST PLS HELP FAST!!!Estimate the solution to the system of equations. (Please also give me the coordinates on the graph)
y = 4x - 2
y = x + 3

Answers

Answer:

(5/3, 14/3) or (1.66, 4.66)

Step-by-step explanation:

Given system of equations

y = 4x - 2 y = x + 3

The solution is the intersection point of the lines

Determine x- coordinate:

4x - 2 = x + 34x - x = 3 + 23x = 5x = 5/3

Determine y- coordinate:

y = x + 3y = 5/3 + 3 = 14/3

So the point is:

A truck is carrying grapefruit juice, pineapple juice, and tomato juice bottles in a ratio of 3 : 1 : 2. If there are 14 pineapple juice bottles, then how many juice bottles in total are there?

Answers

Answer:

84 juice bottles

Step-by-step explanation:

Given the ratio of grapefruit juice, pineapple juice, and tomato juice bottles as

3:1:2

Let the total number of bottles available be R

If there are 14 pineapple juice bottles, then

1/(3 + 1 + 2) * R = 14

1/6 * R = 14

multiply both sides by 6

R = 14 * 6

= 84

This means there are 84 bottles in all

There is a total of 364 marbles in a jar. The ratio
of blue to red marbles is 3:4. How many red
marbles do you have?

Answers

Answer:

Example 1:

In a bag of red and green sweets, the ratio of red sweets to green sweets is 3:4. If the bag contains 120 green sweets, how many red sweets are there?

Solution:

Step 1: Assign variables :

Let x = red sweets

Write the items in the ratio as a fraction.

red/green

Step 2: Solve the equation

Cross Multiply

3 × 120 = 4 × x

360 = 4x

Isolate variable x

x=360/4

Answer: There are 90 red sweets.

Example 2:

John has 30 marbles, 18 of which are red and 12 of which are blue. Jane has 20 marbles, all of them either red or blue. If the ratio of the red marbles to the blue marbles is the same for both John and Jane, then John has how many more blue marbles than Jane?

Solution:

Step 1: Sentence: Jane has 20 marbles, all of them either red or blue.

Assign variables:

Let x = blue marbles for Jane

20 – x = red marbles for Jane

We get the ratio from John

John has 30 marbles, 18 of which are red and 12 of which are blue.

red/blue

We use the same ratio for Jane.

red/blue

Step 2: Solve the equation

Cross Multiply

3 × x = 2 × (20 – x)

3x = 40 – 2x

Isolate variable x

x=40/5

John has 12 blue marbles. So, he has 12 – 8 = 4 more blue marbles than Jane.

Answer: John has 4 more blue marbles than Jane.

A beekeeper collected 25 kg of honey from one of his hives in 2016. This was 25% more than he collected from the same hive in 2015.
In 2017 he collected 10% less honey than in 2016.
What percentage of the 2015 honey collected is the 2017 honey collected?

Answers

Answer:

40 is the correct answer to this question

Let the amount collected in 2015 = X

In 2016 they collected 25% more so in 2015 they collected 1.25x

1.25x = 25

Divide both sides by 1.25:

x =25/1.25 = 20

They collected 20 kg in 2015

In 2017 they collected 25 x 0.90 = 22.5 kg

20/22.5 = 0.8888

0888 x 100 = 88.888% Round the percentage as needed:

In 2015 they collected 88.89% less than they collected in 2017.
