Which of the this is a mathematical translation of "A number increased by 7".

A. a + 7
B. 7 + a
C. 7a
D. 7/a​

Answers

Answer 1
A
the keyword is “increased”. That shows that you need to add instead of multiply. “a” is the secret number. Think of it like a sandwich... the bread is a (the secret number) and the meat is + (increased by) and the other bread is the 7. Hope this helps!:)
Answer 2
the correct answer is A: whenever you see “by #” that number is going to be put at the end of the equation or at least after the variable. “A number increased by 7” in other words, “this number will go up by 7” in equation form equals, (a+7)

Which equation can be solved

Answers

Answer: Choice B)  2x-60 = 180

===========================================================

Explanation:

A bit of the question got cut off. I'm assuming the full question reads "In this diagram, the measure of angle RQS is 60 degrees less than the measure of angle PQS"

The portion underlined is the part cut off where I'm making the assumption. If that assumption is correct, then we have

angle PQS = xangle RQS = x-60

Those two adjacent angles form a straight line of 180 degrees

(anglePQS) + (angleRQS) = 180

(x) + (x-60) = 180

2x-60 = 180

which points to choice B as the answer.

Answer:

Step-by-step explanation:

∠RQS = x - 60°

∠RQS = 180° - x

x - 60° = 180° - x

2x - 60° = 180°

HELP ASAP WILL GIVE 30 points. A toy box measures 4 ft by 3 ft by 2 ft. Explain whether increasing
the height by four times, from 2 ft to 8 ft, would increase the volume
by four times.

Answers

Answer:

yes, the volume would be increased by 4

Step-by-step explanation:

the volume for a box is l x w x h

lets say l = 4, w = 3, and h = 2

this would give us a volume of 24

now calculate the new volume: l x w x 4h

4 x 3 x (4 x 2) = 96 which is 4 times bigger than 24

yes, it will increase the volume by four times.

2 x 3 x 4 = 24
8 x 3 x 4 = 96

(24 x 4 = 96)

If you think about it, you are essentially stacking four equal size boxes on top of each other, which combines is 4x the original box size.

Answer:

x=21

Step-by-step explanation:

so,

50 - 8 = 42 it means 42 shoul equal to (19x - 17x) = 2x.

so if 2x = 42 = 2x/2 = 42/2 = x = 21...

[tex]\frac{m^{6}}{5}[/tex] / [tex]\frac{5}{m^2}[/tex] = [tex]\frac{m^8}{25}[/tex]

Step-by-step explanation:

  [tex]\frac{m^{6}}{5}[/tex] / [tex]\frac{5}{m^2}[/tex]

= [tex]\frac{m^{6}}{5}[/tex] * [tex]\frac{m^2}{5}[/tex]

Answers

Answer:

n = 250

Step-by-step explanation:

To express the ratio, the quantities must have the same measures

2 cm : 5 m

Divide both parts by 2

If BE = 2x + 2, BD = 5× - 3, and AE = 4× - 6, what are the values of x and AC?​

Answers

Answer:

x = 7

AC = 44

Step-by-step explanation:

Find the diagram attached

According to the parallelogram,

BD = 2BE

5x-3 = 2(2x+2)

5x-3 = 4x+4

5x-4x = 4+3

x = 7

Hence the value of  x is 7

Also AC = 2AE

AC = 2(4x-6)

AC = 8x - 12

AC = 8(7) - 12

AC=  56-12

AC = 44

Hence the measure of AC is 44

What is the area of a triangle whose base measures 3.2 centimeters and whose height is 4.6 centimeters.

Answers

Answer:

7.36 cm²

Step-by-step explanation:

What is the area of a triangle whose base measures 3.2 centimeters and whose height is 4.6 centimeters.

The formula for the area of a triangle is given as:

1/2 × Base × Height

Base = 3.2 cm

Height = 4.6 cm

Hence,

Area of the triangle = 1/2 × 3.2 × 4.6

= 7.36 cm²

What is an equation of the line that passes through the points (4, -6) and
(8,-4)?

Answers

Answer:

y = 1/2x - 8

Step-by-step explanation:

(4, -6) & (8, -4)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-4 - (-6)) / (8 - 4)

Simplify the parentheses.

= (2) / (4)

Simplify the fraction.

2/4

= 1/2

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = 1/2x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (8, -4). Plug in the x and y values into the x and y of the standard equation.

-4 = 1/2(8) + b

To find b, multiply the slope and the input of x(8)

-4 = 4 + b

Now, subtract 4 from both sides to isolate b.

-8 = b

Plug this into your standard equation.

y = 1/2x - 8

This is your equation.

Check this by plugging in the other point you have not checked yet (4, -6).

y = 1/2x - 8

-6 = 1/2(4) - 8

-6 = 2 - 8

-6 = -6

Your equation is correct.

Hope this helps!
