Last year, Kenia got a 350 on her 6th Grade Math EOG. This year Kenia earned a 399, which was a high enough score to make a Level 4. What was the percent of increase in Kenia's score?

Answers

Answer 1

Answer:

14%

Step-by-step explanation:

Last year's score = 350

This year's score = 399

What was the percent of increase in Kenia's score

Percentage increase= (new score - old score) / old score × 100

= (399-350) / 350 × 100

= 49 / 350 × 100

= 0.14 × 100

= 14%

The percent of increase in Kenia's score is 14%

Suppose x = 7 is a solution to the equation 4x - 2(x + a) = 8. Find the value of a that makes the equation true

Answers

Answer:

[tex]a=3[/tex]

Step-by-step explanation:

So we have the equation:

[tex]4x-2(x+a)=8[/tex]

And we want to find a such that x = 7 is a possible solution.

To do so, substitute 7 for x. Thus:

[tex]4(7)-2(7+a)=8[/tex]

Multiply the left and distribute the right:

[tex]28-14-2a=8[/tex]

Subtract:

[tex]14-2a=8[/tex]

Subtract 14 from both sides:

[tex]-2a=-6[/tex]

Divide by -2: "

[tex]a=3[/tex]

So, the value of a is 3.

And our equation would be:

[tex]4x-2(x+3)=8[/tex]

And we're done!

PLS HELP NEED ASAP The formula d=rt gives the distance traveled for a rate r and an amount of time t. A car travels at a rate of 60 miles per hour for 3 hours. What distance did the car travel? 20 miles 57 miles 63 miles 180 miles

Answers

Distance = rate x time

Distance = 60 x 3

Distance = 180 miles.

Answer:

180m

Step-by-step explanation:

d= distance traveled => ?m

r= rate => 60m/h

t= time => 3h

Formula=> d=r.t

>d= 60 x 3=> d= 180m

So

d= distance traveled => 180m

r= rate => 60m/h

t= time => 3h

Answer:

The answer is option C

Step-by-step explanation:

To convert an angle from degrees to radians multiply the number by

[tex] \frac{\pi}{180} [/tex]

To convert 334° to radians multiply it by the value above

That's

[tex]334 \times \frac{\pi}{180} \\ = \frac{334\pi}{180} [/tex]

3.) \$0.78$0.78dollar sign, 0, point, 78 tip for a \$5.20$5.20dollar sign, 5, point, 20 order

Answers

1) proportional to Mike's tip

2) Not proportional to Mike's tip

3) proportional to Mike's tip

Step-by-step explanation:

when two things have the same relative sides, they are said to be proportional.

To determine if the other tips are proportional to Mikel's tip, we will, first of all, determine the size of Mikel's tip, then compare the other tips with it.

Mikel's tip:

$1.32 for $8.80

= [tex]\frac{1.32}{8.80}= 0.15[/tex]

Now, let us compare this with the other tips

1.) $2.22 for 14.80

= [tex]\frac{2.22}{14.80} = 0.15[/tex]

proportional to Mike's tip

2.) $1.86 for $10.50

[tex]\frac{1.86}{10.50} = 0.177\\0.177 \neq 0.15[/tex]

Not proportional to Mike's tip

3.) $0.78 for $5.20

8x - 3 = 3x + 2

A. One solution

B. Infinite solutions

C. No solutions

please explain how you got it

Answers

Answer:

A one solution because it's x=1

Step By Step explanation:

this is the original problem

8x-3=3x+2

we want to have x by itself so. . .

we add three on both sides. it cancels -3. And 2+3=5

8x=3x+5

we subtract 3x on both sides so 8x-3x=5x and 3x cancels on the other side

5x=5

we divide by 5 on both sides to get x by itself

x=1

if it was 1=1 or x=x (the same on both side) it would've been infinite solutions. if the numbers didn't match like 4=6 it would've been no solution

Answers

Answer:

8/5 is the answer

Step-by-step explanation:

7/10+9/10

7+9/10( because if the lcm is same in both the expression we can write one of them and do according to the sign)

16/10( adding the number)

8/5( dividing the numbers and finding the value in fraction form)

OR,

16/10

1.6( dividing and finding the value in decimal form)

You can find 7/10 + by 9/10 By adding 9 and 7 which is 16. Then you have to turn the improper fraction into a mixed number. You can do that by dividing 16 by 10. 16 divided by 10 is 1 with a remainder of 6. Which then you put the 1 as the whole number and the 6 as the numerator. Which would be 1 6/10 after that, you have to simplify your answer so you have to find the GCF (Greatest Common Factor) which is 2. So therefore your answer is 1 3/5.

Answer:  4 3/8 ≈ 4.38

Step-by-step explanation:

To start off, note that 4 3/8 is a mixed number, also known as a mixed fraction. It has a whole number and a fractional number. We have labeled the parts of the mixed number below so it is easier to follow along.

4 = Whole number

3 = Numerator

8 = Denominator

To get 4 3/8 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.Step 1: Multiply the whole number by the denominator:

4 × 8 = 32

Step 2: Add the product you got in Step 1 to the numerator:

32 + 3 = 35

Step 3: Divide the sum from Step 2 by the denominator:

35 ÷ 8 = 4.375

That's it folks! The answer to 4 3/8 in decimal form is displayed below:
