Write an expression for the sequence of operations described below.subtract 4 from the sum of 2 and y

Answer:

B. 135, 45, 15, 5...

Step-by-step explanation:

I'll go in order from 135 using the pattern shown (tᵇ/3)

135 / 3

135 = 120 + 15

135/3 = (120/3) + (15/3)

135/3 = 40 + 5

135/3 = 45

All four answer choices show this, so no elimination yet.

45 / 3

45 = 30 + 15

45/3 = (30/3) + (15/3)

45/3 = 10 + 5

45/3 = 15

A and D show 30 as term 3, so they are out.

15 / 3

15/3 = 5

C shows 2 as term 4, so that is also out.

This leaves B as the correct answer.

y=-3.5

Step-by-step explanation:

Answer: 20

Step-by-step explanation:

Answer: x < -1

Step-by-step explanation:

x + 6 < 5

x + 6 = 5

x = -1

x < -1

Now try to prove its correct

A number less than -1 is -2 so we'll try that.

x + 6 < 5

(-2) + 6 < 5

4 < 5

We can tell after substituting -2 for x, that the answer is correct

Oh and I changed the less than sign to an equal sign so it's easier to solve.

Does that help?

Answer:

11.5

Step-by-step explanation:

Find new values:  

140(1+0.05)=147  

68(1+0.25)=85

Last Year This Year

Boys 140 147

Girls 68 85

Total 208 232  

Find overall increase:  

208(1+r)=232

1+r=1.115385  

r=0.115385

Final Answer: 11.5%

The total number of students on the honor roll increased by 11.5%.

The percentage is defined as a ratio expressed as a fraction of 100.

The percentage increase in the number of boys on the honor roll is 5%, which means that the number of boys on the honor roll this year is 1.05 times the number of boys on the honor roll last year:

1.05 x 140 = 147

The percentage increase in the number of girls on the honor roll is 25%, which means that the number of girls on the honor roll this year is 1.25 times the number of girls on the honor roll last year:

1.25 x 68 = 85

Therefore, the total number of students on the honor roll this year is:

147 + 85 = 232

The percentage increase in the total number of students on the honor roll is:

((232 - 208) / 208) x 100% = 11.5385%

Rounding to the nearest tenth gives an answer of 11.5%.

Therefore, the total number of students on the honor roll increased by 11.5%.

Answer:

y=-3/2x+8

Step-by-step explanation:

Alright so first we need to convert this equation to Y=mx+b form.

We get y=2/3x-2

In order for it to be perpendicular, we must use -3/2 as the slope.

y=-3/2x+b

Next we need to find the y-intercept of this

Plug in 6 for x and -1 for y and solve for b

b=8

Hope this helps :-)

problem:

Answer:

No

Step-by-step explanation:

Step-by-step explanation:

the difference of 2x and 15 is less than or equal to the

sum of 4x and 17

i.e.,

2x - 15 < 4x + 17

if you want to find ahead then

2x - 15 = 4x + 17

2x - 4x = 17 + 15

- 2x = 32

x = - 32/2

x = - 2

Answer:

The number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.

Step-by-step explanation:

Every third day implies that they both go the beach and then have a two day break, and then go the beach on the day after.

Put simply, every third day implies one day in three days.

Based on the above, the number times both Mark and Jen will be at the beach on the same day over the next 30 days can be calculated by dividing 30 by 3 as follows:

Number times both Mark and Jen will be at the beach = 30 / 3 = 10

Therefore, the number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.

Answer:

4x +  -6.03 = 2.07

Step-by-step explanation:

first one:

there are four big white boxes so that equals 4x

6 negative ones so its -6

3 negative 0.1 so its -0.3

add up 06 and -0.3 and that's -6.03

second one:

there are two squares that each equal one so that would be two and add the 7 0.1's and that will be 2.07
